ENERGIZER NH12BP-4 AAA Ni-MH 850mAh 1.2V 4-pack standard battery

Ready-to-use AAA Ni-MH cells

This pack supplies four 1.2 V rechargeable AAA batteries rated at 850 mAh each. They arrive pre-charged and ready for immediate installation in compatible devices. The nickel-metal-hydride chemistry avoids the memory effect common in older rechargeable types. Each cell delivers the standard AAA form factor for direct replacement of disposable alkalines.

Reusable cycle life reduces waste

Because the cells are rechargeable, a single pack replaces hundreds of single-use batteries over its service life. Users simply return depleted cells to any compatible Ni-MH charger instead of discarding them. This cuts ongoing cost and landfill contribution for high-drain gadgets. The 4-pack format keeps a spare set on hand while the first pair charges.

Suits everyday electronics with moderate draw

The 850 mAh capacity comfortably powers remote controls, wireless keyboards, clocks and similar low-to-moderate drain devices for extended periods. Digital cameras or portable audio players with heavier current demands will see shorter run times per charge. Very high-drain applications such as powerful flash units or motorised toys may exhaust the cells quickly. For those uses, higher-capacity AAA cells or a different chemistry are more appropriate.
