DIY help on cell replacment/balancing

I am sitting at aswresm house today working on an 01 hybrid battery today and I thought I'd give you guys an idea of what I find. Both physical condition and battery voltages. This car has been sitting for 4 months with no starting. Initially I removed the casing and right away I notice a module that has exploded amazingly it still is producing 7v and had 4400mah. Next we take an initial reading the voltages are all over the place from 4.87 to 7.39. No surprise this car won't start. I'm charging them in pairs and it's taking a long time some of these have taken 5200mah according to the chargers. I'm using 4 of my 6 iMax B6AC to charge these. Settings: Manual: Battery type - NIMH, 5amp charge Notice the weakest modules are 15-20 and 9.
