I currently have 4 Optima Blue Tops for the stereo and 1 Odessey Battery for the boat itself. They can all be run when switched to ALL on the Perko which is what I normally do.
When charging I switch to ALL and let them all charge.
I use a charger that has 2A, 10A and engine start options. I switch this to 10A to charge.
Lately it seems that they are not getting fully charged.
Do I need a different charger that allows for a deeper charge? Can I switch it to engine start (75A I think) to charge or is that too much?
What about buying a different charger that will let me switch to a higher amperage like maybe 20A or something like that?
Ideas or suggestions are appreciated.
