Friends: 0 | The 12v battery on my 06 Prius died very suddenly. I was able to easily jump start it from another car. I called around to various battery and auto parts stores and could not find a compatible battery, and ended up having to pay the dealer $200 for the battery ($170) plus installation and fees. This is unconscionable profiteering IMHO. Anyone know the best channel for filing a complaint and registering my displeasure? |

Friends: 2 | jhg, Welcome to PriusChat. Typically, the recommended 12V battery replacement interval is 4 years. But hard service and extreme temps tend to reduce that number. For the record, how many miles are on your car? Do you live in a very hot or cold climate? Other than the final incident, did you ever have to recharge the battery before? |

Friends: 0 | Thanks Rokeby, I have 46K miles, none of it high-stress. I live in Austin, TX so summer runs from early May thru the middle of October, and the last two winters have been non-existent (4-5 days below freezing each year). The battery failed completely without warning. It started fine in the morning, and was completely dead after a stop at an errand at 3:30 PM. Pressing START resulted in nothing but a very dim Check Engine light that faded out quickly. After hooking up the jumper cables it started immediately, and I was able to drive it to the dealer normally. There was a smell of H2S around the battery, but no evidence of any leaking fluids. |

Since you are driving >15K miles per year, lack of use does not seem to be a problem. My guess is that your battery's failure after two years was a fluke. | |

Friends: 0 | If you feel up to doing a little work yourself, a much better though no cheaper Optima battery installation is described here: Prius Optima Aux That page includes a link to a seller of the Optima and a custom installation kit. |
