Re: APC BACKUPS-RS550 not charging battery
If you left this idle for a year, it's likely your batteries are dead. Lead acid batteries do not take well to being left idle, just like in your car. I have a UPS that I'm not using at the moment, but I leave it plugged in. Best case is these batteries last 2-5 years when plugged in all the time. Dead UPS are always avaliable because the batteries go so quickly.
