Batteries are 4 years old. I check the fluid level at monthly intervals, spray the battery tops with a great spray can from Walmart that turns pink color if it detects any acid on the case, then you flush with water(actually I wipe off with a wet paper towel). This spray (which I can't remember the name of now) takes all that white corrosion right off the terminals as well .

Glad to hear that .2 A is basically what to expct in the float mode. I am reading "idiot" lights on bottom of the Link that indicate I am in the Absorption mode. It used to light up in the Float mode when fully charged. Perhaps that circuitry is messed up.

I will check this weekend for water level, test all cells with hydrometer, and reboot the Link to see if I can get it to light up in the Float mode again.

Thanks for great info here!
