What 12V? Battery for box starter or power supply for the charger? If power supply advised to get minimum 8amp. If battery, 7amp.

Recommend you get a Gel-Cel (more expensive VS lead acid but more easy to handle), > 50Ah. I have a 40Ah battery, not bad pretty heavy when bring to races though.

tat would depend on the type of charger or watever u r going 2 use.different chargers have different ratings,the best would be 2 buy a charger which will provide the charging current slightly above the needed current 2 charge the battery.

eg...
LRP quick charger has a rating of 4Amp,so a power supply slightly above 4Amp would b good such as 5Amp,...

Batteries DO have a ampherage rating. They are rated at Amphere-Hours. So our 3000mAh cells (equals 3Ah) are good for powering a 1 amphere item (say a fan which pulls 1A) for 3 hours.
