Vapex Instant AA Rechargeable Batteries 2500 mAh are the latest in rechargeable batteries technology that retain 80% of their capacity after 6 months and 70% after 12 months compared to standard Ni-MH rechargeable batteries that lose 1% capacity per day. So after 1 month on the shelf regular high capacity 2900 mAh batteries will be down to 2000 mAh.
They are very similar to Sanyo's Eneloop batteries. Suitable for all high drain devices such as cameras, MP3 players, CD players, walkmans, radios, torches, flashlights, toys, remote control cars or indeed any device that uses standard AA size batteries.
Also suitable for low drain devices that are used infrequently such as remote controls and transistor radios.
