How Long Will My Toyota’s Car Battery Last? Honestly, there is no true answer and it may vary drastically from one driver to another. On average, your battery will serve you well for about three to five years when you have a conventional gas-powered model. Hybrid models (like the Toyota Prius) have batteries that can last for up to eight years. In order to do this safely, you need to charge at 0.05C, which for a 6.5 Ah Prius module is 325 mA and it is highly recommended that cooling of the charging modules is applied during the charge. Normally a forming-charge is the first charge applied to a new battery in order to ensure it is fully charged and top-balanced before being placed in This plug-in ability will charge the Prius Prime for up to 25 miles of battery-only use. Beyond this range, the regular hybrid system kicks in. In theory, someone who drives less than 25 miles a day with a Prius Prime could rely solely on plug-in power to charge the car and never need to stop at a gas station. Because Prius hybrids are still relatively new cars, there is only a small sample size concerning how long a Toyota Prius hybrid battery will last. Most Prius owners with vehicles from the early 2000’s claim that their Toyota Prius battery lasted anywhere between 12 and 15 years before it needs a battery replacement. Although the security system for your Prius only requires a small amount of electrical power, it is enough to discharge the battery in about 3 weeks altogether. As a result of this, the Toyota user manual advises that every Prius should be run for at least 30 minutes every two weeks. If your battery does discharge, it may be possible to jeffrey New Member.

I have read that no drive battery has yet to be replaced, although a small number had bad cells that were replaced. It is warranteed for 7 or 8 years, 100k miles anyway, so I would not worry about it, Pete. The latest addition to the hooptie fleet is a 2005 Toyota Prius, and it came from my favorite local wholesale auction, which happened to have a few cheap hybrid vehicles for sale. This Prius was traded in to the Toyota dealer after probably getting a $4000-plus repair estimate for a replacement hybrid battery back. The car was in decent shape Hybrid batteries consist of several individual cells. Like every other battery, they have a shelf life, which means they will eventually lose power capacity. So, how long does a hybrid battery last in a car, anyway? Most hybrid vehicle manufacturers give 80,000 to 100,000 miles or eight to ten years warranty on their hybrid batteries. Here's another option for $1600. New Prius Battery Kit (GEN2, 2004-2009) - New Prius Batteries LLC. Higher capacity than OEM.
