I recently got a 2005 Prius, it needs a new HV battery (or at least it's not working properly). Fan goes on almost straight away, engine never turns off. Big triangle warning light and a couple of others. The "Problem" notification on the Touch screen. Went for a drive today and got another "Problem" with main battery symbol on the Touch screen. Car had bad acceleration, engine higher revs, electric motor not in use afaik. So the battery is the first step to fix it ;p
Should I go for a new one (about $3k installed or maybe I can do it myself) or should I look for a reconditioned one?
Car has done ~200,000km, everything else seems ok so far.
Another question, is there a warranty on the batteries if you do it yourself?
