High-capacity AA rechargeables

Panasonic Eneloop Pro AA cells deliver 2550mAh typical capacity in a four-pack of nickel-metal-hydride batteries. They arrive pre-charged using solar energy at the factory and are ready for immediate use in cameras, flashes, game controllers and other high-drain devices.

Low-self-discharge chemistry

The Ni-MH cells hold up to 85 percent of their charge after one year of storage, reducing the need for top-up cycles before a shoot or trip. They tolerate recharging at any state of discharge without memory effect and operate reliably in temperatures down to minus four degrees Fahrenheit.

500-cycle service life

Each cell is rated for up to 500 recharge cycles, making the pack suitable for professionals who cycle batteries daily. The 2450mAh minimum capacity ensures consistent runtime, while the low-self-discharge trait keeps spares viable for occasional users who cannot meet that cycle count.
