Granny bought me a auto care 4 amp battery charger for christmas (bless her), suitable for most 12 volt 6 cell lead acid batteries from 20ah to 70ah.

My battery is a "Banner Starting Bull" 571/014, which happens to be 71ah What I need to know is will the charger she bought me charge the battery properly or will it damage it?

Thanks in advance.

Big-Dan.
