AccuPower 2900 mAh NiMH AA 4-pack

This pack supplies four AA nickel-metal hydride cells rated at 2900 mAh and 1.2 V each. They suit households, photographers and gadget owners who want reusable power for remotes, toys, flashlights and similar devices.

Best for frequent AA users.

Frequent AA users gain up to 1000 recharge cycles and avoid the memory effect common in older chemistries. Buyers who need lithium voltage, larger capacities, or proprietary cell formats should choose a different chemistry.

2900 mAh capacity sets runtime expectation

Each cell delivers 2900 mAh at 1.2 V, defining how long a device runs between charges. The bundled smart charger refills two or four AA or AAA batteries in four to five hours for AA and 1.5 to three hours for AAA using negative delta-V cut-off and safety timers.

Questions about this item

Does the UltraLast smart charger need anything besides a 120 V 60 Hz wall outlet to charge the four AccuPower AA cells?

No — the charger plugs directly into 120 V 60 Hz mains and can also run from the included car cord or USB cord, so no extra equipment is required.

Will the charger still handle older NiCd AA cells that I already own?

Yes — the charger supports both NiMH and NiCd chemistries and charges two or four AA or AAA cells at a time.

How do I know the 2900 mAh batteries have finished charging?

The LED flashes red while charging and turns solid red when the negative delta V cut-off detects full charge.
