Panasonic K-KJS2MCA2BA AA 2000 mAh 2-pack standard battery

Ready-to-use AA rechargeables

Panasonic Eneloop AA cells arrive pre-charged at 1.2 V and 2000 mAh so they work straight from the pack. The 2-pack suits households that need a few spares for everyday devices. Nickel-metal-hydride chemistry avoids the memory effect of older rechargeables. They replace disposable alkalines in any standard AA slot.

2100 recharge cycles and C-size flexibility

Rated for 2100 charge cycles the pair delivers years of service before capacity fades noticeably. Included C-size spacers let each AA cell power larger-format torches, toys or radios without buying dedicated C cells. Runtime scales with the 2000 mAh rating so high-drain gadgets drain the cells faster than low-draw clocks. Spacers add no electronic function, only mechanical fit.

Low self-discharge chemistry

Eneloop cells retain most of their charge during months of storage so they are ready for emergencies. The 1.2 V output matches nominal NiMH voltage and is compatible with equipment designed for 1.5 V alkalines. No proprietary charger is required; any NiMH charger will replenish the pack. Buyers needing lithium voltage or higher single-cell capacity should look elsewhere.
