A techy at Boats US told me that if an Optima battery is charged at over
13.8 volts for 90 days it is toast... I do not know where he got his info
but he believes it and sells a lot of Optima batteries... he is recommending
some sort of voltage reducer from radio shack or the high price spread
custom voltage regulators ... his real advice was not to buy an optima
unless you are prepared to check the voltage regularly and will dampen down
alternator charge rates to 13.8

Does anyone have the skinny on this?
