If you have the security system, you should have the larger Gr. 40R battery (60Ah). I know it's not a perfect solution, but maybe worth checking to make sure you have the 40R instead of the smaller 96R (52Ah) battery.

It buys a little bit of extra capacity.

Many stores will check the battery and charging system (but not for small 'leaks') with a handheld device. Youir Ford dealer has this too, it's a Rotunda Midtronics tester. It will test the battery state of heath, the starter, and charging system, and is very accurate.

I'd suggest first making sure the battery / charging system has no faults before trying to trace down smaller drains, which can be hard to identify.


Good luck!
