I just bought a new set of Philips Multilife 1.2 V NiMH rechargeable batteries (AA). They're 2600 NiMH.
Thing is, I really wanna maximize the use of these, and get as many years of use out of 'em as poss. My last set of rechargeables had a disappointing lifespan. I've heard that correct initial charging of them is the key.
1) For how long should I first charge 'em?
2) After that initial charge, should I just use them until there's no power in them, and then do another recharge of XX hours? Or should rechargeable batteries be constantly recharged?
3) What about storage? (If I don't use them for months on end, what's the correct charging procedure/frequency?)
4) Is it true that if rechargeable batteries are dropped accidentally, even from a short height, this greatly reduces their lifespan, or does it only moderately reduce it? (I sometimes have butterfingers, lol.)
5) What about my old-ish batteries, which I haven't disposed of yet. Bought them 3 years ago, but have used them irregularly. They're 2100 NiMH. I'm sure there's still some life in them. I have a multimeter. How do I test if there's any power in them? What reading will tell me that there now only fit for the rubbish bin?
Sorry for the long post. Will be very appreciative of your advice on these issues.
Cheers,
