The good news is that the battery computer can be repaired. We reconditioned a hybrid battery for Auto Electrical Solutions Ltd in Palmerston North It had a faulty computer. The tortoise would come on when the battery indicator showed half or 3/4 charge. This is a sure indicator that one of the diode sensors is faulty.
Because the battery is now fixed, it is now possible to check the diodes in the computer and change the faulty ones. This is what AES did and all error codes also went away.
This is good news as it completes the process of repairing and reconditioning the series 1 hybrid battery.
