does anyone know if the Battery Tender Plus charger is ok to use on optima batteries?

 

I've used them on my motorcycle batteries, and my deep cycle battery for my boat. They work great, and I haven't had to buy a battery yet. I see no reason they wouldn't work, or harm a optima battery.

 

I have a dual battery charger on our rescue boat. I installed 2 blue tops in it cause one of the firemen cept filling the regular batteries to the top of the cells. I had to set the charger for the optima (had choice of regular lead/acid or gel battery). Slightly different final charge settings. It charges both batteries separately, priority to the starting battery.

NOTE: This charger was for boat applications and was not cheap.
