[sci.electronics] How to recharge NiCd

tolboel@iesd.auc.dk (Morten Tolboel) (01/14/91)

Can anybody tell me which way is best to recharge NiCd batteries in
order to achieve:

1) Fast recharging or
2) Maximum recharging or
3) Long battery lifetime or
4) Any combination of 1), 2) and 3)

(constant current/voltage or even some kind of modulated current ?)

Please give examples for the following:

 - 2200 mAh 'C'  (baby)     (1.2 V)
 - 1800 mAh 'C'  (baby)     (1.2 V)
 -  500 mAh 'AA' (penlight) (1.2 V)

What if the battery is not completely "dead" but still have 50% of its
power left?
