Twenty-four Powerex NiMH batteries, twelve AA and twelve AAA, on cards with a storage case

Maha Energy Corp.

Maha Energy Corp. Powerex AA 2700mAh AAA 1000mAh NiMH rechargeable batteries combo

SKU CH-VQ3K-7PYMA

Combo pack of twelve AA cells at 2700 mAh and twelve AAA cells at 1000 mAh, NiMH rechargeable, retaining up to 75 and 85 percent charge after storage

  • Battery typeAA & AAA Ni-MH
  • High-capacity AA cells deliver 2700 mAh for longer device runtimes
  • AAA cells provide 1000 mAh capacity for extended use in compact electronics
  • NiMH chemistry enables fast and efficient full charges across both sizes
  • Improved low-temperature performance keeps devices powered in cold conditions
  • Extended storage retention up to 75% for AA and 85% for AAA cells

AA & AAA NiMH combo for everyday devices

This pack contains twelve AA cells rated at 2700 mAh and twelve AAA cells rated at 1000 mAh, all using nickel metal hydride chemistry. It suits households, photographers and hobbyists who run remotes, flash units, toys or wireless peripherals and want a single rechargeable solution for both common sizes. The cells arrive new and ready to charge.

Sustained discharge and recharge behaviour

Under continuous drain the AA cells deliver their 2700 mAh rating while the AAA cells provide 1000 mAh, maintaining steady voltage through the cycle rather than dropping sharply after an initial burst. Both sizes accept fast, efficient full charges and keep that performance over many cycles. After long storage the AA cells retain up to 75 percent of their charge and the AAA cells retain up to 85 percent.

Practical limits of the NiMH standard

Nickel metal hydride chemistry self-discharges faster than primary lithium or alkaline cells, so the pack is not ideal for devices that sit unused for years between uses. The 1.2 V nominal voltage is lower than the 1.5 V of disposable alkaline batteries, which can prevent operation in a few voltage-sensitive gadgets. Extreme cold still reduces available capacity despite the improved low-temperature formulation.

Questions about this item

Do the 2700 mAh AA cells and 1000 mAh AAA cells generate noticeable heat when left in devices all day?

No, NiMH chemistry runs cool during normal discharge; neither the AA nor AAA cells produce noticeable heat in typical use.

What charger do I already need to recharge these Powerex NiMH cells?

Any standard NiMH charger that accepts AA and AAA sizes will work; the pack includes no charger of its own.

Will these new Powerex cells work reliably in older devices that originally took alkaline AA or AAA batteries?

Yes, the 1.2 V NiMH voltage is compatible with equipment designed for 1.5 V alkaline AA and AAA cells.
