Topping up battery with distilled water

I'll drink to that !!!

The wet cell deep cycle in my patrol didn't last 2 years, but I checked the levels probably 4 times a year. I think the bigger killer was the discharging.

I got better results just using standard "starting" type batteries, which is why I've gone to a sealed calcium/calcium cranking battery on both sides of the car.

I guess I'll find out in a year or two?

At any rate, if i have to replace the aux battery every couple of years @ $100 a pop, then life aint so bad.
