Mirror to all on the list; All trucks that are NiMH, whether they were original, or converted later, can be reprogrammed for PbA battery operation. To reprogram the truck it does require the GM Tech2 scan tool as well as the GM TIS application. Due to health issues, I have don...

The BPCM tracks the SOC (State Of Charge) through the shunt during charging and discharging. Your vehicle has a nice charging system. Why not use it? Jeff On Aug 27, 2009, at 4:35 AM, McMullin, Kevin wrote: > I'm replacing the batteries in my truck with a Deka AGM 80AH. They >...

Well, the information you were told is somewhat misleading. The 2A VRLA end of charge leveling is never intended to exceed 14.75v There are instances where extreme imbalance can result in one or more modules exceeding 15v before termination. I have some experience with this, a...

12v replaced only a couple of months ago. I spoke to Jeff and he doesn't think anything I did with the new wiring is the problem. i.e. something new is broken. The "new" thing is the APCM which is apparently $4000 wholesale, $6000 retail and impossible to get anyway. That kind...

Usually, when you buy a part from GM, GM wants the old one back. For some reason I cannot recall now, this one did not go back. The Power Steering Control Module in my S-10E went out years ago, I paid for a replacement, and the replacement failed within the warranty period. Th...

They are not incorrectly labeled. Your truck is native NiMH, the sensor map you're referencing is PbA. The battery # assignment map is entirely different between PbA and NiMH. As your pack is NiMH, the sensor location assignment is 18,19,15,1,4,5 On Jul 11, 2009, at 9:02 PM, M...

Toyota used larger batteries (95AH v 85AH) If the size and number of the cells in modules were exactly the same this would apply. However Volts times Amps equal watts. So if you increase the volts but decrease the amps or increase the amps and lower the volts that needs to be...
