Are you looking to fix your dead Prius hybrid battery because your car won't start? Well, before you jump to the conclusion that your hybrid battery is root of your car troubles, you may want to first take a look at your 12 volt battery in your Prius. If the 12 volt battery is dead, your car will be unable to start as well. Fixing your 12 volt is much easier than dealing with the hybrid cells. To repair your 12 volt battery, here is what you want to do: 1. Open the Prius' hood by pulling on the handle located on the bottom left of the steering wheel. 2. Open the plastic protector to the battery on the top right-hand side of the engine and open the small red plastic lid covering the positive port to the battery. 3. Hook the positive cable, which typically has a white line painted on the rubber, to the positive port of the car giving the Prius current. 4. Hook the negative cable (all black) to the negative port of the car giving current, making sure the opposite end does not touch any other metal before connecting it to the Prius, because the cables may already be electrically charged. 5. Turn on the car giving the charge and press the accelerator slightly to pass enough current to spark the battery in the Prius. 6. Turn the Prius on and drive for a minimum of 20 minutes without turning the engine off; this will re-charge the battery enough so it won't go dead when turning off the engine. If using a battery charger, start the Prius and leave it charging overnight. If this did not fix the problem, then you may have a more serious problem with the hybrid cells.
