Panasonic HHR-70AAA AAA NiMH 700 mAh 1.2 V Flat Top standard battery

Panasonic AAA NiMH 700 mAh Rechargeable Cell

These AAA NiMH cells deliver 700 mAh at 1.2 V and arrive pre-charged with a flat-top terminal. They suit cordless phones, remote controls, wireless keyboards and other low-drain devices that specify AAA NiMH chemistry. The flat-top design means they will not fit equipment that requires a button-top contact. Buyers needing button-top terminals or a different chemistry should look elsewhere.

Check device compatibility before ordering

Verify that your device accepts flat-top AAA NiMH cells and that its charging circuit is designed for 1.2 V nickel-metal-hydride chemistry. Equipment built for alkaline 1.5 V primaries or for Li-ion rechargeables may not charge these cells correctly or could cut off early. The pack contains no charger; an appropriate NiMH charger must be used. If the manual specifies button-top terminals or a different voltage, these cells are not suitable.

Thermals noise and power in normal use

NiMH chemistry runs cool during typical charge and discharge cycles and produces no audible noise. Self-discharge is low: the cells retain about 85 % of their charge after a year in storage. Rated cycle life reaches 1000 recharges, reducing the cost per use compared with single-use alkaline batteries. No active cooling or special ventilation is required in normal indoor operation.
