I've heard both good and bad about about zapping, but as far as I understand, zapping basically can prolong battery life a little, but when it's time to use it, there aint much back anyway.

However, I dont know if that's the case with your packs.

What I do know for sure, is that discharging down to 0,9 volt pr. cell - preferable with an active equalizer - will help a lot. Afterwards, give them a complete charge.

A tray usually takes the cells all the way down to zero volt. This increases the output voltage, when the pack is in charged state. But it's also known for decreasing capasity. Since you're using a tray, this is probably a part of your problem. Taking cells down to zero volts usually introduce some false peaks, which might be your main problem.

Another issue might be your power supply or charger, which can cause false peaks.

Another source to the problem: Storing.

Please tell how the packs perform on the track, mainly about punch, but also about runtime. Also, is your packs sligthly warm after a complete charge? This can help diagnosticing the problem.

the sanyo's have not as much punch as the gp's but that is pretty much normal

i dont have a tray myself i might borrow my cousin's to fix these batteries

im using a millenium pro and im setting it to nimh 2 which doesnt overcharge it. once it hits the peak it stops.
charging them at 5 amps

the batteries come out warm like normal it seems its a bit hotter then it was when i frist got it. but when first got it i was running indoors in the winter. now im running outdoors in around 27 degress celcius weather. thats why its a bit hotter

so what should i do? thanx!

how did you know that your 3300mah battery had turned into 3000mah and 2400 into 1800???

I recommend you get a equalizer with auto-cut off. Integy and Robitronic got some nice ones.
