What are AAA Batteries?
The AAA (triple-A) battery is a dry cylindrical cell defined by its roughly 44.5mm length and 10.5mm diameter. The AAA is commonly used in smaller home devices such as remotes and electronic toys. Triple-A batteries are typically button tops with either a 1.2 or 1.5 voltage, and come with an array of chemistries such as aklaline, NiMH, and lithium. Learn more about AAA batteries here.

Are there rechargeable AAA batteries?
Yes, rechargeable AAA batteries use NiMH (nickel-metal hydride) chemistry and have a 1.2V voltage compared to the typical 1.5V. You can also buy 10440 li-ion batteries, which are the same size as AAA cells.
Note that non-rechargeble triple-A batteries typically have a 1.5V voltage, which may differ from most 10440 batteries (3.6V) and rechargeable NiMH AAAs (1.2V). Always check with your device's user manual to see if a battery voltage, chemistry and terminal-type is compatible.
Do AAA batteries expire?
Yes, all batteries eventually expire. AAA batteries have a range of shelf lives between 3 and 20 years, wholly dependent on the battery's chemistry and storage conditions. 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. For more information, check out our battery expiration guide!
What AAA battery brand lasts the longest?
We don't play favorites at Battery Junction, and runtimes are often dependent on your device's battery drain and operating temperature. Typically, batteries with larger capacities (mAh) have longer overall runtimes. Triple-A cells tend to max out at 2,600 mAh, and you can filter our wide-selection of batteries by 'Capacity (mAh)'.
Do you offer bulk-pricing on AAA batteries?
Yes! A large selection of our batteries can be bought in bulk, letting you take advantage of huge discounts! You can filter our selection of batteries by bulk-eligibility, fill out a wholesale request form, or directly contact a member of our sales team now via phone or email!
