There are several factors that affect this. The most important is the rate at which the device consumes power. A high-drain device like a digital camera will deplete a battery much faster than a low-drain device like a clock. Other factors affecting how long they last are environmental conditions, device usage patterns (whether it is used often or infrequently) and battery size/chemistry.
It’s safe to drop them right in the household rubbish. In 1989, Energizer became the first company to remove all added mercury from alkaline batteries.
Standard alkaline batteries are not designed to be recharged and should never be placed in any battery charger. Attempting to charge alkaline batteries will significantly increase the likelihood for leakage to occur. Rechargeable alkaline batteries made by other manufacturers may also leak if placed in a charger and should only be recharged in a charger designed for that system. Of course, Energizer rechargeable batteries have all the rechargeable power you’ll ever need.
Energizer® Ultimate Lithium batteries provide extraordinary life in digital cameras; they're lightweight and operate well in extreme temperatures. They are the world's longest lasting AA and AAA 1.5 volt cells in high-tech devices.
Battery chemistry and construction differ in the two systems. Energizer® Ultimate Lithium batteries are built in a spirally wound construction. This design helps the battery meet the high current drains of many of today's devices.
Since lithium is a very active material, it provides a great deal of power relative to the amount of material used.
Yes. Much of the concern with the environment centres on heavy metals. Lithium is the lightest metal known.
They provide exceptional life in cameras; they're lightweight and operate well in extreme temperatures.
Yes, Energizer® NiMH Rechargeable batteries are not fully charged upon purchase, so they need to be charged before the first use. However, because they are not fully discharged, either, they should actually charge in less time before the first use.
No. Energizer® NiMH Rechargeable batteries do not have the memory problems typically associated with older Nickel Cadmium rechargeable battery technology. NiMH Rechargeable batteries can be recharged after a few hours of use or whenever convenient. If batteries have been stored for more than 1 month, be sure to recharge before using to maximise power.
Energizer® Advanced Lithium batteries differ from alkaline batteries in chemistry and construction. They are built in a spirally wound construction. This design helps to meet the power demands of many of today’s devices. They provide long-life in digital cameras, as well as gaming and audio devices. Due to proprietary lithium battery technology, Energizer® Advanced Lithium batteries are lightweight and operate well in extreme temperatures.
No. You should never mix different battery chemistries. Different battery chemistries discharge different in a device, which could potentially lead to premature battery failure of the lower capacity battery.
Energizer scientist Lew Urry hand-built the first commercially viable alkaline battery in 1959. Today, his prototype cell is on display at the Smithsonian Museum of Natural History in Washington DC.
To get the best performance, keep moisture from clogging the air hole by opening the hearing aid compartment every night. Turning your hearing aid off when not in use can also help get the best hearing aid battery life possible.
Store your flashlight in a cool, dry place that is conveniently located and easy to reach in case of an emergency or power outage. Don't store your flashlight in direct sunlight.
Energizer® MAX® is the perfect alkaline battery for long-lasting, high performance power. They are perfectly suited for low-drain everyday devices like torches, smoke detectors and radios. However, if you’re using high-tech, high-drain electronics such as a digital camera you may want to use Energizer® High Tech Batteries.
It is not recommended to mix different types of batteries in a device. This can significantly increase leakage and reduced performance. Always replace used batteries with new, fresh batteries of the same brand and chemical make-up — preferably Energizer.
Yes. Batteries can be short-circuited by metal items such as coins, keys, paper clips, etc. A battery that experiences a short circuit can become very hot, increasing the potential for leakage and personal injury.
Typically, alkaline batteries will not leak under normal conditions. However, the potential for leakage is significantly increased if batteries are subjected to overcharging, mixing with other types of battery in a device, mixing of fresh and used batteries, physical damage, extended exposure to high temperature or deep discharging. Alkaline battery leakage is extremely dangerous and contact with bare skin should be avoided. In the event that battery leakage comes in contact with your skin, flush the area for 15 minutes with large amounts of water.
It is normal for batteries to become warm during the charging. This is because the charger is passing energy into the battery. However, battery temperatures should return to room conditions within minutes after the charging process stops.
We do not recommend using our chargers in foreign countries that have a different power supply. Using overseas voltage adapters can result in permanent damage to the charger or wall plug.
We recommend that chargers be unplugged from the wall plug and the batteries be removed after the charging sequence is complete. This allows the charger to reset prior to the next usage.
Batteries that are not loaded into the charger will not charge.
It depends on the charger. But beware, some chargers only charge pairs of batteries at a time (2 or 4). If one or three batteries are installed in these chargers, the single battery (not in a pair) will not charge.
"Flashlight" is the American term for what we know as a Torch.
Identify the one that best suits your needs. Generally, you’ll want something reliable and tough, that shines a bright beam and that uses batteries efficiently.
Keep the batteries in your torch when you aren’t using it.
That way, it’ll work when you need it. Turn it on and off occasionally if you don’t use it for a prolonged period to ensure it still works and that the batteries still contain charge. Always make sure you have back-up batteries at hand just in case.
They provide exceptional life in cameras; they're lightweight and operate well in extreme temperatures.
Zinc air batteries can and should be disposed of in your normal household rubbish.
Battery sizes are standardised across all brands. Most manufacturers colour code hearing aid batteries according to industry standards: Just look for the colour standard to find your battery size. The most common battery sizes are 10, 13, 312 and 675. To make recognition easier: 10—yellow, 13—orange, 312—brown, 675—blue.
The lifespan of a hearing aid battery is determined by the amount of time it is used continuously, as well as the volume to which the hearing aid is set and, in many cases, the make of hearing aid itself. Consult your hearing care professional to determine length of hearing aid battery life.
