Panasonic BK-4HCCA4BA Eneloop Pro AAA 950mAh 4-pack

High-capacity AAA Ni-MH pack

This four-pack of Panasonic Eneloop Pro AAA cells delivers 950mAh typical capacity for high-drain devices. They arrive pre-charged using solar energy at the factory and are ready to use immediately. The low self-discharge chemistry holds up to 85% of charge after one year of storage. Each cell can be recharged up to 500 times without memory effect.

Ni-MH chemistry and cycle limits

Nickel-metal hydride chemistry provides stable voltage under load but has lower energy density than lithium alternatives. The 500-cycle rating assumes proper charging and storage conditions; deeper discharges or high-temperature use will reduce total service life. Self-discharge is low yet not zero, so cells left unused for many months will eventually need a top-up charge. Extreme cold performance is rated down to -4°F.

950mAh typical capacity threshold

The 950mAh typical and 900mAh minimum ratings determine whether these cells meet the runtime demands of your device. High-drain electronics such as camera flashes or wireless controllers benefit from the elevated capacity versus standard Eneloop AAA cells. Devices requiring longer single-charge runtime or higher current delivery may need a different chemistry or larger form factor.
