How do you revive faulty rechargeables? (powerex)

[Mankul]

I left a pair of faulty rechargeables (AAA powerex 900mAh) for quite a long time without charging in an FM transmitter and after several months I can't charge the batteries anymore... The batts are less than a year old..

when I used the powerex cold rapid charger (MH-C401FS) , it gave me blinking red light.... I left the batts in the charger (with the red blinking lights) for more than 24 hrs, and try to recharge again... still the same, blinking red lights...


whats happening to the rechargeables? how come can die just like that? :cry:

eastgear.com can do something about it? ... :dunno::dunno:

pair of "faulty rechargeables"

if they were faulty, why didn't you replace them in the first place?

try using the refresh function

maybe not faulty.. but dead is a better word... they worked fine last time.... now they can't be charged...

the C401FS charger doesn't have a refresh option

you can bring it down to EastGear for them to use the C9000 to jump start.

You should bring them down to Eastgear and get them to exchange a new set for you.

nimh are not good for low power consumption stuff

you ahve to charge and discharge them a few times to get the capacity back. but it may not work if its too damaged..

Try a different charger?

My Sony 2500mAh batteries now cannot be used with the 15-minutes Sony charger they came with. The fast-charger will always blink at me, indicating that there's something wrong with the batteries.

Funny thing is that I am still able to charge them up using my 2-hours charger, and a super-slow overnight charger and they work fine.
