I have 6 volt Optima's in our 40,47, and 48. Recently following the Texas Packard Meet, the 48 failed and it was less than a yr old. Replaced it and 4 months later it failed. Advance Auto refunded my money as they could no longer source them. I use a trickle charger on them and start them at least once a week. Do they need a maintainer or some other charger or am I just charging too much? Or, are they no longer dependable?? Tommy
