My yellow Optima started playing up during the week. Even after a charge it failed to register more than 11.5 volts. When left connected to the cranking battery all day it managed to flatten it, necessitating the use of jumper leads.
I took it back to place of purchase and they charged it overnight, and noted that one cell became very hot.
The sticker on the side says purchased 6 April 2001, so just under 8 yrs old. It has been roundly abused throughout its life.
I reckon if you get twice the mileage of a conventional battery, the premium price becomes very reasonable.
The cranking battery is a red optima about six years old. I wonder how much longer it will last, and will it die when I least want it to.
What sort of life have others had from their deep cycle batteries?
