  • Includes protective case for eight AA cells

High-capacity AA cells for demanding devices

These Powerex PRO AA NiMH batteries deliver 2700 mAh of capacity at 1.2 V. They suit high-drain electronics such as flash units, wireless transmitters and portable audio gear. The pack includes eight cells and a protective storage case.

Cool operation with efficient charging

Nickel-metal-hydride chemistry keeps the cells cool during normal charge and discharge cycles. Fast, efficient full charges are supported without excess heat. Self-discharge is low enough that the pack retains up to 75 % capacity after extended storage.

Consistent output through long sessions

Improved low-temperature performance helps maintain voltage under sustained load. The ultra-high capacity design supports prolonged use in continuous-drain applications. Cells are manufactured in Taiwan for reliable long-lasting performance.

Questions about this item

How do I install the eight AA NiMH cells and which step do people get wrong?

Insert each cell with the positive button toward the device's + contact; the common mistake is reversing one cell, which prevents the pack from delivering 1.2 Volt per cell.

What maintenance or replacement will these 2700 mAh NiMH batteries need later?

Recharge them every few months during storage; they retain up to 75% capacity after extended periods, but will eventually require replacement when run-time drops noticeably.

What limit appears first under sustained high-drain use?

Voltage sag under heavy load is the first limit; the 1.2 Volt nominal output drops faster than lower-capacity cells, signalling the need to recharge.
