I have a 1998 NWH10 Toyota Prius. My problem with the car is when i first turn the car on, its runs normal for a few seconds, then all of a sudden the turtle mode light comes on indicating low battery and the car begins over revving the engine to what sounds like 4500-5000 rpm. When i check the battery meter on the multi function display unit on the dashboard, it shows the battery is full and in the green section and not dropping into the orange/low section. please help
I had found a guide that let you rebuild Toyota Prius hybrid battery. This Guide would also be a good investment for the future. Hybrid batteries have a limited life span of 8 years or 150,000 miles on average. So if your car hasn't had a bad battery yet you can be expecting it soon as the 8 year mark is coming up on all 01'-03' Prius.

Have both your battery and alternator inspected. Turn it on, disconnect your negative battery cable, if it dies, you need an alternator, if not, then you may want to test your battery for bad cells.

I dont think the problem lies with the 12v battery, my car being a hybrid has the 12v battery to first start the electric motor which then starts the petrol motor, once the car has started the 288v hybrid battery takes over, the 12v is a standard car battery with positive/negative terminals, whereas my main 288v battery is nothing like ive seen before. 2nd is the car doesnt have an alternator, the electric motor recharges the battery's. One more problem i noticed the other night is when the car begins to over rev, the cooling fans of the main 288v battery seem to also over spin, as if the battery is overheating or something, its got me really confused
