LILEAD S80 dual 12 volt lithium battery performs better than lead acid batteries in more weather conditions. It can charge between temps of 0 and 55 32°F ~ 131°Fand can discharge between -20 and 60 -4°F ~ 140°F at 100% rate.

LILEAD dual lithium leisure batteries need to be above freezing in order to charge them. As a result, it is best to use the batteries in a climate controlled location (not on the tongue of a trailer or using a lead acid battery compartment that has to be ventilated, thus allowing freezing air to circulate around the battery).

LILEAD dual lithium leisure batteries can be placed in an insulated space, inside the yacht/ boat/ RV or other climate controlled areas. Some users have suggested using a Battery Heating Pad that you can find online. We recommend using the battery in a climate controlled location.
