Where to mount a second Battery??

[Joe_Black]

You should really try just using the Yellow Top and a high-output alternator before resorting to a second battery setup. Even with two batteries now, if the Red Top is getting drained a second battery will as well but just not as quick. That means your battery is picking up the demand the stock alternator can't meet. Two, three or more batteries just means you'll go a bit longer before having to recharge. Batteries are for supplying start and overload power, while your alternator recharges the battery and supplies operating power.

Optima recently released a significantly higher capacity battery YellowTop Group D75/25 in a larger case that might be easier to mount than 2 batteries.

Thanks again for all the input . . .

I have decied to go with a big Yellow Top and a Kill Switch to prevent drain when I park her for long periods of time.
