Just picked up an 09 Street glide this week. The voltage meeting has been reading right on 15 all the time. Is this normal? I'm used to 13-14.

 

Anything above 12 is good.....jmo

 

Lead/acid batterys like we all used to run required constant maintenance (which most never got) and running them above 13.8 would cook out the water pretty quick.

The gauges on these things aren't the most accurate, but 15 is good. It's likely running around 14.8 or so. The AGM batterys like being kept "hot" which allows them a longer life. They don't loose water since they're sealed, so boiling one dry doesn't happen.

 

Good info, thanks. That's what I wanted to be sure of.
