Charge it.
Read it.
Trust the number.
Every Powerex charger runs on one idea: don't guess at battery health — measure it. Independent channels, real capacity readouts, and conditioning cycles that bring tired NiMH cells back to spec.
Charger-Analyzers
Five chargers built for different bays, budgets, and battery formats — from a pocket USB charger to an 8-slot rig that takes AA through D cells.
A pocket-sized USB smart charger for 1–4 AA or AAA cells, powered straight from any 5V/2A USB port — no wall brick required.
8 independent bays with Soft, Turbo, and Conditioning modes. Fanless and thermally protected, with a capacity readout after every deep-condition cycle.
The Turbo model: 8 bays at up to 2A per cell, a one-touch battery health analyzer, and active thermal management to keep packs cool at speed.
4 fully programmable channels — Charge, Break-In, Discharge, and Refresh & Analyze — for anyone who wants to test, not just top up, a battery.
The all-format charger: 8 slots take any mix of AA, AAA, C, or D cells at once, with rugged fixed contacts built for daily professional use.
Not sure which charger fits your setup? Match bay count and battery format first — everything else is a bonus.
Rechargeable Batteries
Two NiMH lines for two different jobs: maximum runtime for demanding gear, or a battery that's ready the moment you open the drawer.
Built for runtime
High-capacity AA cells engineered for high-drain devices, rated from -20°C to 50°C and good for roughly 500 recharge cycles.
Ready out of the pack
Low self-discharge cells shipped already charged, across AA, AAA, C, D, and 9V, so devices don't sit waiting for a first charge.
Low self-discharge AAA cells, 4-pack, for everyday household and office gear.
Maximum-runtime AA cells, 4-pack, built for high-drain, professional devices.
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.
