ENERGIZER AAA

AAA batteries are your trusty sidekick for all those small electronics around the house, like TV remotes, MP3 players, and digital cameras. Though some gadgets that need more juice opt for the larger AA batteries, which pack triple the power of a AAA.

Thanks to modern tech being more efficient and compact, many devices that once needed AAs are now designed to go with AAAs. For the curious: a AAA battery measures 44.5mm in length and 10.5mm in diameter.

Alkaline AAA batteries tip the scales at about 11.5 grams, while their lithium counterparts are lighter at 7.6 grams. If you go for rechargeable (Ni-MH), expect them to weigh in between 14 and 15 grams. AAA alkalines and lithiums run at 1.5V, whereas Ni-MH or NiCd batteries come in at 1.2V. The alkaline AAA batteries usually offer a capacity between 900 and 1155mAh.

Battery Life: How long your AAA batteries last depends on the type and usage. Typically, alkaline AAAs can last from 10 to 24 months when stored properly. Rechargeables (Ni-MH) can keep going for up to 5 years with the right care and recharging practices.

Rechargeable Batteries: AAA rechargeables, mostly built with Ni-MH (Nickel Metal Hydride) technology, are a smart, cost-effective, and eco-friendly choice, letting you power back up multiple times.

Manufacturing Materials: You can find AAA batteries in various types, with alkaline, lithium, and Ni-MH rechargeables being the most common players out there.

Pack Quantity: Your typical AAA battery pack usually comes with a set of 4, though this can vary based on the maker and battery type you pick.
