AUTOMATIC AA NICAD Battery Charger with 4541
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 it’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.
