Fire Power Coldweather Lithium Battery 390 CCA HJTX20CH-FP-B-C
The Fire Power Coldweather Lithium Battery HJTX20CH-FP-B-C (490-2818) is a 390 CCA, 12V lithium iron phosphate (LiFePO4) powersports battery engineered specifically for cold-weather starting, rated for reliable performance in temperatures down to -4°F. It delivers strong, consistent cranking power at a fraction of the weight of a conventional lead-acid battery, with an integrated BMS and a built-in state-of-charge LED gauge.

Cold-Weather Use
Due to the nature of lithium chemistry in extremely cold conditions, it may be necessary to warm the battery if the machine will not turn over. This can be done by applying a load to the battery (running the lights/handwarmers or repeatedly pressing the starter button). Snowmobiles may need to be pull-started once in the morning; once the battery is warm it will start the machine normally for the rest of the day.
