the voltmeter said 77.3, so it's off a volt, and was when I added up the old battery numbers.
Should I try and run the batteries down low before I charge, or does it matter?
Should I let the vehicle rest after my drive home before charging or just plug it in as soon as I get out?
Should I let it rest for a while after charging before I drive?
The numbers were higher when the batteries were brand new, like 13.23 or so. It could just be they are stabilizing. Or I damaged them somehow.
Sometimes my daily ride will only be 25 miles or so, and when I get home the voltmeter will be around 70v. I'm sure after they rest from the drive they come back up to at least 72 or so. I was wondering if since they are not drained, it might affect the length the charger runs.
Thanks
If they are floodies don't worry about it too much, mine are up to a half volt out of balance and there is nothing I can do about it (and their gel which is worse)
