Any of the DC experts out there that can help me out, on a 12V sealed lead acid battery what should the voltage be on a healthy fully charged battery? These are the batteries commonly used on emergency lighting, gate openers and alarm systems.
Also, what is the optimum charging voltage?
I am troubleshooting one of my toys that has a low battery shutoff, but I don't know what it shuts off at. The battery measures about 13.5 volts. As soon as the load is applied it drops to around 12 volts and the automatic shutoff kicks in.
Thanks...Brian
