Default Erratic batteries

I bought some used batteries about a month ago, see them here...

http://www.rctech.net/forum/attachme...3&d=1205880649

They seem to work erratically. I have two different chargers but they don't charge well on either. After a couple of cycles now, they don't hold a charge well at all.

They were assembled except for wire. I soldered deans & 12 gauge wire on (the wire is from Lowes... I couldn't get ahold of any of the noodling deans wire).

We have some GP3300's that are still working well. What am I doing wrong? Did I buy bad batteries? Is it the wire? The charger I bought with them, a Duratrax Intellipeak Digital, doesn't seem to work now, either (it did at first). The charger status light comes on, but won't go into a charge mode. I use only DC, not the AC adapter.

Thanks in advance for any advice.

Find someone with a CE Turbo Charger and Novak Discharge Tray. Have then cycled and see what numbers you get on the turbo. High resistance probably means they are bad. If you can find someone to cycle them individually and you can find enough good ones to make a pack or so; it might we worth the work. However they must be unsoldered and the ends cleaned for a cycler to work correctly.

Some series of 4200s were bad. Many have exploded. I have seen three at my track. I bought 8 packs and within a month only two were dependable. I gave them to a guy who couldn't afford much and said if the local guy who did matching could make something out of them, he could keep whatever he was able to restore and match. I think he ended up with 3 decent packs.
