thats very much approx, just an indication. May not what A the charger actually charges at.
Chances are its a dumb charger, so it wont be able to detect when the batts are fully charged .
However Nicad's are more robust than more modern rechargeables, I guess that why they are still used.

btw, dont assume that fully discharging batts is the way to do things.
Its the fastest way to permanently ruin some type of batts .

1242245 2011-11-06 22:59:00 The plug in timer sounds like an excellent idea. 1101 (13337)
1242246 2011-11-06 23:42:00 Thank you 1101.
I realise it is only approximate so the timer will be used.
Thanks all for your input.

1242247 2011-11-07 10:14:00 A simple way is to divide the capacity by 10 and charge at that rate for 14 hours, so 1.2AH = 120 mA for 14H, if you charge at a higher rate reduce the time proprtionately. 350mA would be approx a 3rd of the time so 4-5 hours, except the higher current probably means it's a little less.

Another even simpler thing to check, fully charged NiCads get warm, when overcharged they get hot. So if it's warm turn it off.
