  Battery Charger Ideas
The charger is a small molded unit that probably doesn't supply more than an amp and this circuit would have trouble with much more.
Here is how it works: When the battery voltage is low, the voltage at the base of the first 2N4401 (on the right) is not sufficient to turn it on and the second 2N4401 is biased on by the 10k resistor.
When the battery is nearing full charge the light will begin to flash on and off and after a few hours the light will only come on occasionally.

 NiCd Battery Charger
Proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life.
I decided from the specifications and from my preferred style of use (throw it in the charger and expect it to be good next time I reached for it) that the design of a better battery charger would require the charger to sense the condition of cells and charge accordingly.
Most users know where the battery's "knee" occurs; it is when the original equipment first starts to show signs that the battery performance (and hence voltage) is suddenly dropping, and it is a good idea to place it straight on charge at this point.

 NiMH Battery Charger FAQs
Although most manufacturers do not recommend that you leave a battery in the charger for long periods of time, many people leave their batteries in the charger on trickle charge for days or weeks to keep their batteries "ready to use".
While a timer type charger is less expensive to manufacture than a smart charger, it can lead to overcharging and battery damage if batteries are frequently charged before they have been discharged (that is, the batteries are used for a short time and then fully charged again).
Other features that contribute to a battery chargers smart status are: temperature sensor, discharge and conditioning features, battery test features and even timers to limit the total length of the charge so even if you leave it plugged in, it turns itself off after a preset time.
