Charges AA cells on a 5-hour or 14-hour rate
with automatic turn off
Rechargeable batteries are very popular for use in all sorts of devices, especially those requiring a high current.
The most common type of cell is the AA or penlight and although thousands have been sold, there are very few low-cost chargers to keep them in tip-top condition.
Most of them simply charge them at the slow rate and never turn off – you have to remember. Charging a cell for longer than necessary reduces its life so itâ€™s important to cease the charging operation when the time is up.
To solve this problem we have designed an automatic charger to charge any number of AA cells, from 1 to 8 and turn off when the cells are charged.
