Two NiMH lines for two different jobs: maximum runtime for demanding gear, or a battery that's ready the moment you open the drawer.
High-capacity AA cells engineered for high-drain devices, rated from -20°C to 50°C and good for roughly 500 recharge cycles.
Low self-discharge cells shipped already charged, across AA, AAA, C, D, and 9V, so devices don't sit waiting for a first charge.
Maximum-runtime AA cells, 4-pack, built for high-drain, professional devices.
Maximum-runtime AA cells, 8-pack, built for high-drain, professional devices.
Low self-discharge AAA cells, 4-pack, for everyday household and office gear.
Ready-to-use AA cells, 4-pack, for everyday household and office gear.
High-capacity C cells, 2-pack, for lanterns, radios, and larger devices.
The largest Powerex cell, 2-pack, built for power-hungry D-size equipment.
A precharged 8.4V 9-volt replacement, ready to swap in.
A slightly higher-voltage 9.6V cell for gear that wants a bit more headroom.
Every size, side by side — capacity, storage life and low-temperature performance for the full Powerex Pro and Precharged lineup.
