A few weeks ago in Colorado had 30 below for 3 nights and had to jump the stock battery every morning, so bought the 20 cell antigravity battery. Had a 30 below night and was still 10 below and it cranked it over for quite a while before it finally started. It is a little heavier at 4.2 lbs than some of the others but has 600 cranking amps and is easy to mount. It is not quite as tall or wide as the stock battery but the mounting posts locations are identical.
awesome customer service!!!
