Okay so I have an Imax B6AC charger and the plan was to cycle through my batteries thats been sitting over the winter.
Anyways so I start discharging my glowdriver battery and I got absolutely nothing out of it. Okay fine I think and set it on charge. But I only get about 200 mAh into it before its finished. I discharge it again and get like 700 out of it :S
I do repeat that a few times, the last time I put it on charge it went up to over 4k and still wasnt finished. The battery got really hot so I pulled it off and went to bed. I put it on discharge again and again only got like 700 out of it. The funny thing is that after it had discharged, I tried it on a loose glowplug and it still had charge, I even left it there for a while and it was glowing perfectly.
I thought the battery must be busted so I thought Ill try with a starter battery.
These are 2 7.2 volt Nimh cells with 3000 mAh in each.
First I charge it but I only get around 720 mAh into it but I hadnt discharged it first so I thought it still had some charge.
I then discharge it and get almost exactly 3k out of it. Which is fine. Put it on charge again, and this time I only get 140 mAh into it
Now I put it on charge again directly after that and its on 260 now and keeps going, well see when it thinks its finished.

So whats going on? Are all the batteries busted or is the charger broken, cause its only about a year old.
