Yes but very few do this because there's either a $1350 core charge fee or you need to return an OEM pack as core so a set of new modules costs...
Temperature and cooling certainly plays a role in charging curve, higher temperature leads to reduced charge amount and earlier peaks. I stopped...
This is excellent data, along with your individual voltage numbers point at module 4 and 5 as being the problem. The rest of the pack seem to be...
All those Dr. Prius screenshots were taken with the battery charging or with a very slight discharge @ high SOC, outside of the delta SOC reading...
Check each latch sensor for continuity with a multimeter. If you don't have a multimeter you can use a wire to jump each sensor plug to find the...
You don't need to open the cover to see whats inside, you can get peek by removing the upper plastic vent, the opening should be large enough to...
I've seen this on many 3rd gen Prius with a bad hybrid battery. The hybrid system uses the generator motor to quickly spin down the gas engine,...
This is all good advice. With a typical MAF failure the vehicle will not stay start or stay running but will run after unplugging the sensor. I...
Delta is an unreliable parameter for a multi-cell module. You can trigger the delta early in the charge if you have insufficient cooling while...
Battery ECU secrets and teardown (warning: geek content) | Page 2 | PriusChat I've been replacing these connectors for 8 years now. If the...
The corrosion you see on the battery computer pins actually starts at the negative battery module terminals, travels down the sensing wires into...
So, I did reduce the charge to 6500 mah after seeing others also recommend that mentioning that any charge past 6500 is dead and useless and all...
I would recommend to not charge them to 7500mah, you're probably cooking them and your battery doesn't have that much capacity anyway. Stick to...
It definitely sounds like you have weak/failing hybrid battery. With a good battery the charge indicator rises and falls slowly. This was done...
This is true if your testing method involves using a multimeter to probe voltage at rest or under a light load. It use to be easy, just swap some...
Wanted to share some data and observations about hybrid battery reconditioning and how a failing battery can be brought back to life without...
I know this is old but in case somebody runs across this thread looking for answers I just replaced a 260 with a 220, according to the above table...
Any place that does nickel plating will probably know what to do but I suggest doing the prep work beforehand to save on costs/convince them to...
This is the classic battery ECU/sensing harness issue. You need to address this ASAP before it gets worse and results in a burned out ECU,...
Dr Prius and Hybrid Assistant monitor all 14 block voltages and plot/log them and compare the differences between them. This difference between...
