Dreaded P0A80 Code - Car Running / Charging Good.

They were definitely giving out different readings even at static as mentioned above. depending where I placed the probe, it gave out different readings due to the heavy corrosion. Only way to get the proper reading was to probe the tip of the actual battery terminal and thats how I was able to get proper standing voltage readings. I cleaned the front bus bars (top) and haven't done the rear (bottom).




I a should be getting the new busbar/nuts kit today or tomorrow and will install them and very confident readings will no longer variate. If there was variation in readings due to the corrosion at static, I can only imagine while under load and driving.

As for the Prolong, I would love to have one of those kits but #1 they are too expensive new andI cannot find a used one at a good price. If you have one or know someone at a good price LMK.

 

Are you able to see the serial numbers while they are still on the car? Because, I am not removing the modules at this time. BTW, there is a clear vent tube that goes on the end attached to the long black tubes that is missing the tubing that goes into the back of the seat into the bottom of the car. I have read that latter gen 3 went away with that tube but want to confirm.

 

Agreed.

 

ill check

 

I got the serial numbers. most of the cells have the first 9 alpha/digits the same and 3 are totally different numbers. Does that mean those have been replaced? I can tell someone has been in the battery before because some securing bolts are missing and the orange safety screw on top was also missing.
