Followup to Prius battery woes

[kj]

I would just replace it. I was having odd electrical problems, two different stores tested the battery and said it was fine. Difficulties starting, lights turning on by themselves, weird stuff. I went back in, the guy at autozone literally berated me for buying a new battery, but it immediately fixed all the problems. In fact, it's been a few years. No way it wasn't the battery, so the testing doesn't always work. In my opinion, it's basically the cheapest troubleshooting step you can take.
