I just ran a reverse pulse charge through on one of my 6 year old sets of trinity 2000's on my novak millenium charger and it gave me these values;
10.62V 1884seconds 2617mAH to me that seems a little high i was giving them 5.0A and using the recommended voltage cutoff threshold.
Comments/explaination please

Those are very Nice High Resistance Batteries!!

Ya those things look dead Maybe a good cycle or just practice packs.

Why do they look dead, admittedly they are a few years old (read 7) but ive looked after then, they took ages to charge due to reverse pulse charging.

The reverse pulse charge could give a misledaing capacity rating on charge, because it also includes a small amount of discharge as part of the cycle.

The high peak voltage level indicates a battery with high internal resistance, which means it will have less punch on the track.

Okay, can someone give me some "good" values that i would be looking at for a linear charge at 5.0A. I thought that the higher the voltage the better as it gave more punch for racing stock, you guys have told me the opposite. :-/

Lately, the better packs I've seen are showing around 9.0-9.3 volts at peak(that's at 5 amps, it can be a tick higher at higher charge rates). When you see the peak voltage topping 10, that generally means that the pack's internal resistance has gone up considerably, so while it's early voltage may be ok, it'll drop off FAST, & heat up more than one with lower resistance, & at that point, I usually relegate that pack to practice duty.....
