Battery

[Matt_focus_zetec]

Right i think most of my problems are down to the shear fact i have a naf battery on my car its only a 390 70ah i think same as mrs fiesta one and i was told by ford a calcium one is desgined for the focus as it uses a smart charging system using anthor battery could harm damage or even make it misfire slightly which my car still trys to stall a little but not as bad and when using auxially equipent it dims lights and all sorts is it worth buying one of these batterys

Thanks

Matt

calciun batterys are recomended for the focus smart charge system which is to complicated for a lead acid battery. go with whats recomended as a normal battery would only last a few months before cells will start to give up.
