What voltage equals 100% charge?

This depends on what kind of battery you are using, such as 12V lead-acid battery 13.2V full charge, Terpolymer lithium battery 4.2V full charge, lithium iron phosphate battery about 3.4V full charge, this parameter can be seen from the battery or charger. Thanks for your questons.

Mine doesn't show 100% charge when the batteries are fully charged. I know the batteries are good and at 100%. I have a 36 volt system. Help?
