It includes a 16-bay smart LCD charger with independent slots, 4 AA Ni-MH 3000mAh batteries, 12 AAA Ni-MH 1100mAh batteries and 3 battery cases. The cells are 1.2v and have low self-discharge.

Holding the REFASH button starts a discharge cycle intended to help restore and extend battery life. A rear heat-dissipation hole helps prevent overheating during extended charging. The batteries can retain charge for up to 3 years after a full charge and operate down to -20° C. The AAA cells arrive partly pre-charged; a full charge before first use is recommended.

The source says performance is best after 3-5 charge/discharge cycles and that the cells can be recharged up to 1200 times. Rechargeable Ni-MH cells reduce disposable-battery waste and heavy-metal pollution. Suitable devices include remote controls, digital cameras, electronic toys, hand-held games, radios, flashlights, alarm-clocks, toothbrushes and shavers that use AA or AAA batteries.
