Accupower AccuLoop NiMH battery pack 16 AA 2600 mAh 16 AAA 1100 mAh 4 C 4500 mAh 4 D 10000 mAh

Mixed-size NiMH pack

This bundle supplies 16 AA cells rated at 2600 mAh, 16 AAA cells at 1100 mAh, 4 C cells at 4500 mAh and 4 D cells at 10000 mAh. Every cell uses NiMH chemistry and delivers a nominal 1.2 Volt output. The assortment suits households or workshops that run devices across all four common cylindrical sizes. Buyers needing 9 Volt cells or lithium chemistry will not find them here.

Pre-charged low-self-discharge cells

The batteries arrive pre-charged and hold 85 percent of their capacity after one year in storage. This means spares can sit in a drawer or emergency kit without a top-up cycle before first use. The low-self-discharge trait also reduces waste from cells that go flat on the shelf. Users who require a higher first-use voltage or a chemistry that tolerates extreme cold will need a different technology.

1.2 Volt NiMH limitations

Each cell provides 1.2 Volt, which is lower than the 1.5 Volt of alkaline primaries, so some voltage-sensitive gear may show reduced runtime or fail to start. The fixed capacities of 2600, 1100, 4500 and 10000 mAh cannot be altered, and the pack contains no charger, so a compatible NiMH charger must be sourced separately. Devices that demand a 9 Volt form factor or a higher single-cell voltage are not supported by this assortment.
