stick/saddle? can check voltage of individual cell in saddle config. if you have voltmeter handy. Might have a dead cell or more yet charging will still show some current going into the pack.

Heard any hissing sound or saw fluid oozing out of any cell during charging?
How was temp. during/after charging? Can you hold the pack after charging or it got unbearably hot?

Should the pack wakes up magically...do reduce the delta-v a bit; 10mv per cell is a tad bit too much i believe

can we know your charging and discharging profiles? amp/cut-off/temp if available; discharge amp/cut-off plus any battery conditioning yada yada yada...

seriously 1 year is really too long for NiMH to be "sleeping" without serious "wakeup call". NiCad behaves differently, even GP and IB do not want to be treated similarly

Hi all,

it has been at least a year i did'nt use my battery, & last weekend, i decided to take out my R/C and play.

At my surprise after 2, 3 times charging and discharging, my NiMH GP3300 battery could charge around 3450. but the problem is when i try to play with it.. there no punch at all... the car not even moved...

My other battery NiCd 1700 works very well...

any suggestion??? by the way, i'm using LRP Pulsar Competition (The 1st version)

Thanks
