Hello - first time on forum here. I just paid nearly $450 for a new battery for my 2015 Prius C, and wanted others opinion on if this was a right move or not, and looking for advise on how to maintain my battery going forth, given I only drive once or twice a week (10-20 miles per week) nowadays, working from home since March 2020. I bought my 2015 Prius C brand new in 2015 and had my first real problem today.. (Feb. 2021 today).. the car would not start and the check engine light was on. It turned back on when the car was jumped - it didn't take much, like 30 seconds and it was back up and running. I took it to the dealer to make sure everything is okay and they recommend the battery to be replaced. And so I did.. and paid nearly $450 for it The techs said the battery went bad because I haven't been driving the car often. Like I mentioned earlier, I only drive once or twice a week (10-20 miles per week) since March 2020. Does this sound right? I guess I don't understand the logic, because since there's way less usage and wear and tear, I expected less maintenance on my end. Also, I don't understand why the battery maintenance indicator didn't light up, and instead the check engine indicator lighted up? They recommended I buy a automated-battery charger to maintain the battery going forth. If this is true, is there any recommendation on what I should buy and how often do I need to do this? It seems I need a plug-in, but I live in a condo with outside parking... Has anyone had similar experience? Any suggestion, advice would be greatly appreciated. Thank you for your time.
