[QUOTE="audiolife, post: 7179366, member: 541383"] A fully charged agm battery will rest higher than 12.6 volts (2.1 volts per cell ) most will rest between 13 to 12.8. Every major manufacturer will tell you when it is at 12.6 they need to be recharged. A battery is parishable and has self discharge. The more you let it drop in that range and leave it sit under full charge without bringing the cell up to full charge is a good chunk of the battery you can lose. Is 2.1v per cell a real number or is it estimated? Is 2.12 volts per cell bad? What about 2.14? [/QUOTE]
