Energizer Power AA LR6 alkaline batteries, pack of 8

Energizer alkaline AAA batteries are the compact equivalent of AA batteries. They efficiently power the small electronic devices used every day. I consider these batteries essential for every home—they’re genuinely useful in all kinds of situations.

Technical specifications of AAA batteries

These alkaline batteries provide a nominal voltage of 1.5 V and an energy capacity of 900 to 1155 mAh (equivalent to 3240 to 4158 coulombs). That’s three times less than an AA battery, but it’s exactly what small devices need. Each battery weighs approximately 11.5 grams, with a very compact format: 44.5 mm in length and 10.5 mm in diameter. For comparison, AAA lithium batteries weigh around 7.6 g (making them lighter), while Ni-MH rechargeable batteries weigh between 14 and 15 g.

Common uses and compatibility

AAA batteries are commonly used in remote controls (TVs, set-top boxes, air conditioners), portable MP3 players, compact digital cameras, pocket flashlights, lightweight electric toothbrushes, wireless mice, and small toys. Honestly, this is the most requested battery size in stores for last-minute replacements. If you need a battery and aren’t sure which one to choose, AAA is often the right answer for small devices.

Advantages of alkaline technology

• Stable 1.5 V voltage throughout the battery’s life
• High capacity (900-1155 mAh) for extended power
• Ultra-compact and lightweight format (11.5 g)
• Long shelf life without rapid self-discharge
• Compatible with all standard AAA devices

How to choose between AAA, AA, and other sizes

AAA batteries are smaller and less powerful than AA batteries, but they are more than sufficient for lightweight devices. If your device consumes a lot of power (a professional camera, high-powered music player), an AA battery will be better. For small everyday devices, AAA is the logical choice. Between us, I always recommend keeping a supply of AAA batteries at home—they’re so often useful that you’ll wonder how you ever managed without them.

Who these batteries are for—and who they aren’t

Ideal for: Any household that uses portable electronic devices (remote controls, toys, small lamps, cameras). It’s a practical, straightforward purchase. Less suitable for: If you’re looking for a power source for a high-consumption device or prefer rechargeable batteries (Ni-MH) for environmental reasons, take a look at our rechargeable accessories in the rechargeable sex toy collection.

A friend’s advice— Buy your batteries in packs and store them in a cool, dry place. Alkaline batteries can be stored for years without any problems, unlike rechargeable batteries, which slowly self-discharge. It’s an investment you won’t regret.
