Battery Light on dash

[durango kid]

I started my Spyder and the battery light was flashing.I pulled the battery out and checked the volts 12.1. I put it on my battery charger and it went to 12.8 I also tested the battery with a battery tester(no dead cells, was fine). I reinstalled and checked voltage going in. 13 volts. Does anyone know what voltage is suposed to be going into the battery? Thanks
