Why OPTIMA YELLOWTOP is the Better Choice for a 4X4

Many 4x4s are heavily-modified from an electrical standpoint. Popular electrical modifications can include winches, refrigerators, aftermarket stereos, auxiliary lighting, onboard compressors and more. With all these added demands, a YELLOWTOP OPTIMA battery that is designed for both starting and deep-cycle use, is a better option over a REDTOP battery, that is designed and warrantied for starting applications and not deep-cycle use, including winching. 

We would also recommend keeping your YELLOWTOP fully-charged to at least 13.0-13.2 volts whenever possible to maximize battery performance and lifespan. We're so confident this is the case, if you buy an OPTIMA battery from us and an OPTIMA Digital 1200 battery charger at the same time, we'll extend the free replacement warranty coverage on your battery by an additional year!
