Duracell AA HR6 Rechargeable Batteries 1300mAh NiMH (4 Pack)

The Duracell AA HR6 is a 1300mAh nickel-metal hydride (NiMH) rechargeable battery supplied pre-charged in a 4-pack. Each cell delivers 1.2V nominal voltage and can be recharged hundreds of times in any NiMH-compatible charger, offering a reusable alternative to single-use alkaline batteries for devices with moderate to high power draw.

Designed for wireless keyboards, game controllers, remote controls, digital cameras, torches and other household electronics that cycle through batteries frequently, the 1300mAh capacity provides extended runtime between charges compared to lower-capacity rechargeable cells. The batteries arrive pre-charged and ready to use out of the pack, and Duracell's Power Preserve Technology retains charge for up to 12 months when stored unused, so they remain functional even after long periods in a drawer.

The NiMH chemistry handles the charge-discharge cycles required by devices that draw current in bursts, such as camera flashes or wireless mice, without developing the memory effect associated with older nickel-cadmium (NiCd) batteries. Unused cells carry a 5-year shelf life guarantee from Duracell, and the rechargeable format reduces both the volume of disposable batteries sent to landfill and the long-term cost per use compared to buying fresh alkalines repeatedly.

How many times can these batteries be recharged?

Duracell states these can be recharged hundreds of times. The exact cycle count depends on usage patterns, charger quality and discharge depth, but typical NiMH cells of this capacity deliver 500-1000 charge cycles before noticeable capacity loss.

Do they come charged or do I need to charge them first?

The batteries arrive pre-charged and ready to use immediately. You can insert them into a device straight from the pack without needing to charge them first.

What charger do I need?

Any NiMH battery charger rated for AA cells will work. Duracell produces dedicated chargers for their rechargeable range, but third-party NiMH chargers are also compatible. Avoid using chargers designed only for NiCd batteries, as they may not deliver the correct charge profile.

How long do they hold their charge when not in use?

Duracell's Power Preserve Technology allows these batteries to retain charge for up to 12 months when stored unused. This makes them suitable for emergency torches, remote controls and other devices that sit idle for long periods between uses.
