I am trying to recharge a 8 cell 600mA NiCad battery for my transmitter. I'm using an Accu-cycle elite charger. The problem is that I can't get the battery to have a strong voltage. When I test the battery on a voltmeter, the voltage isn't sufficient for it to be safe to use. I think the voltage reads about 4.4v. I tried cycle charging the battery to see if that would improve, but the maximum charge the battery will hold is 80mah. I don't know much about batteries, so much help would be appreciated. Is there anything I can do to retrieve the battery's voltage and the 600 mA it use to hold? Thanks

If you are setting the charger properly (you most likely are or it probably would give a warning message) then I'd say the battery is history. Sounds like it's a transmitter battery? I wouldn't take a chance; I'd just replace the battery.

Have you tried cycling the pack?

Using your voltmeter check the individual cells. There are probably some dead cells in the pack. As has already been mentioned, probably best to throw it away. Replace it with NIMH cells. Same physical size, much greater capacity.

It is gone. That is what those chargers are for, determining if the pack is good or not. You can get your volt meter and check each cell and see which ones are bad just to confirm the bad ones. Sounds like a pack that has sit a long time without use.

Nicd and Nimh packs are only good for about 3 years maximum if they are maintained properly. Many do last longer, but the chances of a pack failure go up quite a bit at that point. Toss it and get a new one. They don't cost much as new pulls from Ebay, or get one from all battery or hangtimes.

My Feedback: (2)

sometimes those chargers dont like charging through the TX charge port. if you are doing that, try unpluging the battery charging it that way

there is a diode in most transmitters......that is why you can't cycle a battery through the transmitters charge port.....unplug the battery and hook it directly to the charger before buying a new battery
