About how long does the high voltage battery last? I’m use my car mostly on local roads so the electrons are being used as designed. So your 2013 Prius C hybridIt depends on your 12v battery health, but no longer than 2 weeks. If the battery is weak then it may last even less time. If you're not going to drive for long periods you should disconnect the 12v battery entirely or put it on a battery tender. The hybrid battery only needs to be topped up once every 2 months or so.
If you’re wondering just how often you should do it, there is no definite answer. On average, you should replace your Toyota’s battery every 8-10 years or 100,000-150,000 miles. However, it’s also possible your battery will last till you finally sell the car, but it’s best to be cautious and still look under the hood from time to time.
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 If you buy a new battery from Toyota for about $3000, that will be good for another 10 years. At that time, it would be a VERY GOOD car to pass on to a new driver. Nothing will be comparable for that money. Do not spend money on a rebuilt battery as that will fail again shortly and you'll keep doing that over and over again. IUpAQ.
