For more information, check out our battery expiration guide! What AA battery brand lasts the longest? We list the rated shelf life on all our product listings when available so you can make an informed choice when buying spares or bulk cells. AA batteries have a range of shelf lives between 3 and 20 years, wholly dependent on the battery's chemistry and storage conditions. Always check with your device's user manual to see if a battery voltage, chemistry and terminal-type is compatible. Note that non-rechargeble double-A batteries typically have a 1.5V voltage, which may differ from most 14500 batteries (3.6V) and rechargeable NiMH AAs (1.2V). You can also buy 14500 li-ion batteries, which are the same size as AA cells. Yes, most rechargeable AA batteries use either NiMH (nickel-metal hydride) or NiCd (nickel-cadmium) chemistries.

This is extremely important if you want to keep a bunch of extra AA and AAA rechargeable batteries in your drawer and grab fresh ones when you need them instead of waiting for the charger.Įmmeline Kaser is an experienced product researcher and reviewer in the field of consumer tech. This refers to how much charge the batteries lose when they aren’t in use. If you’re buying batteries for devices that require less power, like wall clocks and remote controls, a lower capacity is fine. If your devices use a lot of power, then high-charge capacity is essential. Rechargeable AA and AAA batteries are defined by charge capacity, which is given in mAH. Look for rechargeable AA and AAA batteries that are rated for at least 500 recharge cycles, or up to 2,000 recharge cycles for higher-end batteries. The life of a rechargeable battery is defined by how many times you can charge it, use it, and charge it again before it no longer works. What to Look for in a Rechargeable Battery Long Life To avoid ruptures, be sure you're not inserting batteries in the wrong direction, especially for long periods of time, and store your batteries (or the devices they're living in) away from heat sources and in dry conditions (to avoid corrosion and deteriorating the case, as well as the battery cavity of the device itself) It's extremely rare that consumer AA or AAA batteries will explode. Size: AAA | Type: NiMH (nickel metal hybrid) | Capacity: 1,100mAh | Recharge Cycles: 1,200 | Pre-charged: Yes, only 15% Their larger capacity also means they typically take longer to charge than 800mAh AAA batteries. While these batteries are technically pre-charged and useable out of the pack, they’re charged only to 15% capacity and will need several hours on the charger before they’re at full power. They’re good for up to 1,200 recharge cycles. These batteries are also LSD, or “low self discharge,” so they retain that larger capacity for longer-after three years of regular use, they should still be able to charge to 80%. While most AAA rechargeable batteries have an 800mAh capacity, these have a whopping 1,100mAh capacity, meaning they last longer between charges and are an ideal choice for electronics that draw a lot of power. Size: AA | Type: NiMH (nickel metal hybrid) | Capacity: 2,000mAh | Recharge Cycles: 1,000 | Pre-charged: YesĮBL may not be the most recognizable brand name, but these rechargeable batteries are an Amazon favorite for a reason. But if you want to use these in electronics that are on for longer stretches of time or use a lot of power, like a set of string lights or a video game controller, you may find you need to recharge these batteries pretty frequently. That’s quite a bit of time for devices that are used infrequently or draw a minimal amount of power, like TV remotes or flashlights. If you aren’t using them right away, they can maintain a charge for up to a year in storage.Įach charge gives these batteries 5.5 to 8 hours of use. These batteries are pre-charged and ready to use right out of the package and can be recharged about 1,000 times in their lifecycle, potentially replacing hundreds of single-use batteries.Įnergizer’s “Extended Life Composition” also promises up to five years of regular use before they need to be recycled. They’re also made from 4% recycled batteries, which makes them that much more environmentally friendly. This set of eight AA batteries from Energizer is a great household pack for keeping remotes, cameras, and kids’ toys up and running year-round. Runs down somewhat quickly between charges
