    • No. Never mix battery types—such as include alkaline, heavy duty, and rechargeable—in a single device. Battery leakage may occur.

    • No. Never mix old and new batteries in a single device—battery leakage may occur. Replace all batteries in a device at the same time.

    • Do NOT put loose batteries in your pocket. Batteries should be stored in a cool, dry location. Avoid temperature extremes. Keep batteries in original package until you are ready to use them.

    • Batteries can't deliver much power when they are cold. You may find that the flashlight kept in your car in the middle of winter casts a faint beam. Let the batteries warm up to normal temperature, and try them again before you decide to replace the batteries.

    • No. Batteries should be removed from any device that will be stored for long periods of time.

    • Alkaline batteries can be safely disposed of with normal household waste, since the Mercury-Containing and Rechargeable Battery Management Act passed in 1996 that phased out the use of mercury in alkaline batteries. That means they aren't nearly so toxic when disposed in landfills. Never dispose of batteries in fire, as this could cause an explosion.

    • No. Household batteries (RAYOVAC® FUSION™, HIGH ENERGY™, Zinc Carbon batteries and rechargeable batteries such as RAYOVAC®'s Recharge and Recharge Plus (NiMH), and fully drained lithium primary batteries) are not hazardous waste. They are qualified as non-hazardous after having undergone government required testing.

      Certain others, such as lead acid rechargeables and Nickel-Cadmium (NiCd) batteries, are required by regulation to be recycled. If you throw them away then they are a hazardous waste. Recycling logos on these products contain the information you need for finding your recycling outlets.

      For specific chemical and technical information check out our Safety Data Sheets.

      Additional Information

      All Alkaline, Rechargeable Alkaline, Rechargeable Nickel Metal Hydride (NiMH), Zinc Carbon, and drained lithium primary batteries made by RAYOVAC® are not a USEPA hazardous waste. Zinc Air and Silver Oxide in typical consumer quantities are not USEPA hazardous waste (see below for information pertaining to industrial large quantity generators). Our Material Safety Data Sheets note that non-hazardous wastes are suitable for ordinary disposal methods, providing that there is not some other applicable state or local regulation which directs otherwise. Please view the MSDS pertaining to your particular battery type to find proper disposal methods - Safety Data Sheets.

      From time to time some states, counties, or local governments enact regulations naming a specific compound or element hazardous. In effect, this makes many of the consumer products that contain that material potentially covered by the rules. In other cases, "batteries" is used generically when the rule is targeted toward automotive lead acid batteries. In these cases, it takes time to correct the regulatory language. In other cases, the household batteries we produce may be undesirable for the type of waste management chosen by a city or municipality such as when composting or waste-to-energy incineration is used. Those rules do not make the household battery waste hazardous; they just require different management, often making that management more difficult or costly.

      Part II :

      There are some batteries, such as Nickel-Cadmium (NiCd), which are Universal Waste (the term "universal waste" is potentially applicable to waste batteries only if they are considered "hazardous"). Collection of Nickel-Cadmium batteries is required by law. They are not classified as EPA hazardous waste as long as their destination is recycling. For specific information about environmental legislation relating to batteries, please visit NEMA's web site, the EPA, search the US Code of Federal Regulations, in Europe search EUR-LEX, or contact an appropriate government agency. Other types of commonly used batteries, such as silver oxide batteries, are not regulated for the general consumer but may be regulated for the industrial user. Industrial users who may generate over 100 Kilograms per month of certain regulated hazardous wastes or over 1000 kilograms of any type of hazardous waste may need to treat their waste silver oxide batteries as hazardous waste. Silver oxide batteries contain precious metals that may be recycled. For a list of potential recyclers go to www.nema.org. Many retailers who replace watch batteries as a customer service will also take small quantities of silver oxide batteries from the consumer for recycling.

    • You can find a list of recycling firms that may be able to process waste batteries at the National Electrical Manufacturers Association web site, www.nema.org.. These firms generally charge fees and may require pre-sorting of various batteries. Mixtures of waste batteries will require special packaging and transportation. For details contact the recycling firm of your choice.

      Neither NEMA or RAYOVAC® guarantee the list includes all potential recycling firms. The list does not constitute a recommendation regarding listed firms.

    • We do not take them back. However, RAYOVAC® does fund the RBRC, a take back program for rechargeable batteries.

      Additional Information:

      RAYOVAC® policy does not allow the return of batteries from consumers and other accounts for several reasons:

      • There is no systematic collection scheme nation-wide handling all batteries, and no method for sorting when collections have occurred.
      • Collection and transportation back to RAYOVAC® facilities would result in a net negative effect on the environment, (fuel use, recoverable material, and safety concerns).
      • Alkaline, Zinc Chloride (Heavy Duty & General Purpose), Rechargeable Alkaline, Rechargeable Nickel Metal Hydride (NiMH), Zinc Air, Silver Oxide, and drained lithium primary batteries are clearly not a hazardous waste as confirmed by EPA methods of testing.
      • Current recycling efforts rely on the customer to sort, ship, and in some cases (such as large volume generators such as RAYOVAC®) pay the cost of recycling. The Rechargeable Battery Recycling Company (RBRC), funded in part by RAYOVAC®, offers free recycling of some battery types, visit them at www.call2recycle.org for more information. However; for other battery types current sorting and recovery technology makes it unfeasible for potential recyclers to set up a process due to cost, limited usefulness of recovered materials, and small volumes. Independent studies have shown that there is a net negative environmental effect of recycling due to collection, transportation, sorting and handling these products.

    • Each year in the US thousands of people swallow button cell batteries, including hearing aid batteries. In most cases the battery passes through the body; however, sometimes they can get lodged in the body and cause serious problems.

      It is important to make sure to correctly dispose of your hearing aid batteries. Follow these tips to help prevent accidental ingestion.

      • Keep out of the reach of children
      • Make sure all battery compartments of games and toys are secure
      • Do not leave batteries out where they can be mistaken for medicines or pills
      • Do not put batteries near the mouth

      If a battery has been swallowed call Poison Control immediately at 1-800-222-1222.

      For more information about battery safety please visit: http://www.poison.org/battery/

    • Most manufactures removed mercury from hearing aid batteries by June 2011. (While household batteries (such as alkaline) containing mercury were eliminated in the mid-1990s, button-cell batteries like those for hearing aids were exempt.)
    • Battery life is determined by the type and amplification of your hearing aid, as well as the hours you wear it. Your hearing care professional can tell you the battery life to expect.
    • The most commonly used hearing aid battery sizes are 10, 13, 312, and 675. Most manufacturers use an industry-standard color code to identify the battery size.

      You may notice that different manufacturers often place different letters before or after the battery size. For instance, 13A or R13ZA may look different, but both codes represent size 13 batteries.

    • Zinc air batteries are ideal for hearing aids. With a unique construction that utilizes air from outside the battery, these batteries pack maximum energy into each cell. Using zinc air batteries in your hearing aid will give you clearer tones, fewer volume adjustments, and fewer battery replacements.
    • Store your hearing aid batteries at room temperature. Avoid temperature extremes, as heat will shorten the life of the batteries, and refrigeration is not recommended.

      Metal objects such as coins and keys can short out batteries, so don't carry batteries your pocket or purse. Always be sure to store and discard batteries in places that cannot be reached by infants or children.

      If a battery is swallowed, see a doctor immediately. For recommended treatment you can call the National Button Battery Hotline at 202-625-3333.

      For more information on hearing loss, call the-not-for-profit Better Hearing Institute at: 1-800-EAR- WELL (327-9355) Monday to Friday 9:00 a.m. to 5:00 p.m. EST.

    • Zinc air batteries uses air as a source of power, and the tab provides a seal that ensures freshness until the battery is ready for use. To activate the battery, simply remove the tab, wait one minute to allow air to activate the ingredients, and insert the battery into your hearing aid. (Note that replacing the tab when the battery is not in use will not extend the battery life.)

    • It stands for milliampere hour. It indicates the battery's capacity. The higher the mAh, the more charging of devices you can do before you need to recharge the battery.

    • The number of times you can recharge the battery before it will no longer perform.

    • Any device that can be charged by a cord that has a Standard USB end, which will plug into the portable charger.

    • Our batteries are rigorously tested and sealed with industry certified standards. What does this mean for you? RAYOVAC® products are both safe and reliable.

    • For optimal performance, recharge before use. Using the included cable, plug the Micro-USB end into your RAYOVAC® Portable Charger. Connect the opposite end into a USB power source (wall, car, or computer). Charging should start automatically. Most RAYOVAC® Portable Charger Models also have LEDs that will illuminate when charging is complete.

    • The battery pack can be recharged at any time, no matter what the battery level is. The battery does not need to be empty prior to recharging.

    • RAYOVAC®'s 9V Lithium battery will only last 10 years in ionization smoke alarms. However, RAYOVAC®'s 9V Lithium will extend the life of most high drain 9V lithium devices significantly more than a standard alkaline battery.

    • The RAYOVAC® 9V Lithium will work properly in any other smoke alarm requiring the Ultralife lithium battery. Under normal use conditions, the battery should power ionization smoke alarms for up to 10 years. Please note that smoke alarms should be replaced every 10 years, as they lose sensitivity over time due to age and dust.

      Also note that many smoke alarms come with recommendations to replace the battery with a specific brand of 9V battery (oftentimes Alkaline or Zinc Carbon chemistries). The RAYOVAC® 9V Lithium is also an acceptable replacement battery in these devices and will power any ionization smoke alarm for up to 10 years.

    • As a general rule, batteries, including lithium, should not be left in a product once the battery is discharged. The 9 V lithium batteries from RAYOVAC® are hermetically sealed and the chance of leakage is quite small.

    • The specified storage temperature range for RAYOVAC® 9V Lithium batteries is -40° C to 60° C. However, all batteries do best when stored in a cool (not cold) dry location.

    • An Ionization smoke alarm uses an ionization chamber, which is an air-filled space between two electrodes, and permits a small, constant current between the electrodes. Any smoke that enters the chamber absorbs the alpha particles, which reduces the ionization and interrupts this current setting off the alarm.

    • To determine whether you have an ionization-type or photoelectric-type smoke alarm, look at the label on the back of the alarm. If it's an ionization type there will be a statement on the label similar to the following: "This device contains 0.9 microcurie of americium." If such a statement is not on the label then you have a photoelectric alarm.

    • In the US, Oregon state law (ORS 497.297) requires a 10 year smoke alarm battery. Michigan state law (MCL 125.1504c) requires a 5 year smoke alarm battery which can be satisfied by some alkaline batteries but they recommend a Lithium 9V battery. Louisiana state law (R.S. 40:1573 and 1581) requires a 10 year sealed lithium battery smoke detector in one or two family dwellings sold or leased after January 1st, 2011. Many other towns, cities, and municipalities also require 10 year smoke alarm batteries. Please contact your local authorizes to learn more.

      • Installation
        The National Fire Protection Association recommends installing smoke alarms on every level of your home, including the basement, making sure that there is an alarm outside every separate sleeping area. New homes are required to have a smoke alarm in every sleeping room and all smoke alarms must be interconnected.
      • Maintenance
        Regular cleaning of smoke alarms can prevent false alarms caused by the buildup of dust or other contamination such as flies. Photoelectric (optical) type alarms are more susceptible to contamination due to possible interference with the light source and sensor. A vacuum cleaner can be used to clean both ionization and photoelectric alarms externally and internally.
      • Testing
        Test alarms at least monthly by pushing the test button.
      • Replacement
        Smoke alarms become less reliable with time, primarily due to aging of their electronic components, as well as from dust and contamination, making them susceptible to nuisance false alarms. Replace all smoke alarms, including alarms that use long-life 10 year non-replaceable batteries and hard-wired alarms, when they are 10 years old, or sooner if they do not respond properly when tested.
    • Following is advice from the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration's SafeTravel.dot.gov web site on flying with battery-powered devices:

      • Batteries pose little risk contained in the devices they power. Taking the battery out of the device does not enhance safety. To be safest, carry the device with you, not in your checked baggage. Do not remove the battery!
      • Carry your battery-powered devices or spare batteries in your carry-on baggage. In the passenger compartment, flight crews can better monitor safety conditions to prevent an incident, and can access fire extinguishers, if an incident does happen.
      • Finally, if you must carry a battery-powered device in your checked baggage, package it to prevent inadvertent activation. Cordless power tools, for instance, should be packed in a protective case, with a trigger lock engaged.

      Many travelers like the convenience of readily available spare batteries. It's safe to travel with spare batteries, as long as you follow these simple spare battery tips:

      • Pack spare batteries in carry-on baggage. In the passenger compartment, flight crews can better monitor safety conditions to prevent an incident, and can access fire extinguishers, if an incident does happen.
      • Keep spare batteries in the original retail packaging, to prevent unintentional activation or short-circuiting.
      • For loose batteries, place tape across the battery's contacts to isolate terminals. Isolating terminals prevents short-circuiting.
      • If original packaging is not available, effectively insulate battery terminals by isolating spare batteries from contact with other batteries and metal. Place each battery in its own protective case, plastic bag, or package. Do not permit a loose battery to come in contact with metal objects, such as coins, keys, or jewelry.
      • Use only chargers designed for your type of batteries. If unsure about compatibility, contact the product manufacturer.
      • Take steps to prevent crushing, puncturing, or putting a high degree of pressure on the battery, as this can cause an internal short-circuit, resulting in overheating.
      • Please see the following site for more information about traveling with batteries:
        http://safetravel.dot.gov/whats_new_batteries.html
    • RAYOVAC®'s 9-volt battery is designed for safe operation under a wide range of usage and environmental conditions. A key design feature is the use of Safety Shutdown Separator.

      RAYOVAC®'s 9-volt battery is constructed using a safety shutdown separator, which upon either an internal or external short circuit, or current overload condition, will prevent thermal runaway within the cell. The cell electrodes, consisting of a lithium anode and manganese dioxide cathode, are separated by a safety shutdown separator, which is a microporous tri-layer membrane with a single layer of polyethylene membrane between two layers of polypropylene membrane. When a cell is overloaded or short circuited, the polyethylene membrane layer melts upon reaching a temperature of 134° C, significantly reducing ion flow (i.e., current). The reduction in current permits the cell to accept a short circuit or overload condition and shutdown without venting. The safety shutdown is a non-reversible process; once the cell has shutdown it is no longer usable.

    • Lithium batteries will last longer than any other battery types, including alkaline and zinc carbon (lowest cost) batteries, in most high drain devices. For example, RAYOVAC®'s 9-volt lithium battery will last for 10 years in an ionization-type smoke alarm (the most common type), compared to about 3 to 5 years for an alkaline battery and just 1 year for a zinc carbon battery. In a photoelectric smoke alarm the lithium battery will last anywhere from 3 to 7 years vs. about a year for alkaline. Depending on the specific device, the same approximate ratio holds true for other security devices such as door/window transmitters, infrared motion detectors and glass break detectors. It is generally a good idea to follow the manufacturer's battery recommendations.

    • Lithium batteries can be used in intrinsically safe circuits in some cases. A current limiting device may or may not be necessary depending on the device. The battery itself is usually not rated as being intrinsically safe but is tested as part of the entire device. One example where a RAYOVAC® 9-volt lithium battery is being used in an intrinsically safe device is a Personal Alert Safety System (PASS) carried by firefighters, sometimes called a "fireman down alarm."

    • Lithium-manganese dioxide batteries do not exhibit an actual self-discharge mechanism due to the physical separation of the lithium anode and manganese-dioxide cathode. What does occur, however, is a very gradual degradation of the chemistry over time, which can be equated to self-discharge from a capacity loss perspective. In that regard, you can expect a capacity loss of approximately 1.5% per year for our batteries. This loss occurs both in storage and in use.
