When referring to the hybrid
When referring to the hybrid's battery, it failed to be specific. There is a 12 volt in the rear and then then there are cells located and encased behind and below the rear seats. My 12-volt lasted over 9 years. As for the cells, I have 28. If one cell should fail to maintain say an at least 6.5 charge then you can simply replace ithat cell at about $90 per cartridge, at your own labor in about 2 hrs. the first time, only bc you want to be sure you know what you're doing as to not get electrocuted or cause damage to car. It isn't difficult; I learned from a how-to video. I keep hearing stories from others, their Prius costing them several thousand for "battery" replacement. I only paid $210.00 for my 12 volt battery. I simply can't understand why or how thousands were necessary to shell out. How can that be possible? Does that mean the dealer changed out all cells, instead of testing for the non performing one? If so, that seems unnecessary, unless of course, for their own profit.
