Any suggestions for the best deal on a replacement 12v battery? I see costco offering an AGM with a 36 month warranty for $178. I've heard AAA will come and install a battery, but I can't find price or warranty info.
This battery has way more amp-hours and is only $110... I put these in all the Prius I work on. Great battery! 12 Volt (12V) 55 Amp (55Ah) VRLA AGM Sealed Lead Acid Battery 55 AMPS HIGH CAP | eBay
Wow that's great thanks. The yellow top battery I used to buy has skyrocketed in price to $289. But this one you found is a big savings even over the less expensive batteries available at costco/walmart. It will fit properly in 2010 Prius?
You put washers slightly large than size of terminal on the top and bottom of terminal and use a bolt, slightly longer than ones it comes with. As in the washers are like the bread of a club sandwich and the bolt is a tooth pick and the car's battery terminal is the meat in the middle.
