CHLX Series lithium batteries include all the advantages of the HLX Series with the added benefit of cold weather operation. Internal heating technology allows the battery to continue charging, even when the ambient temperature is well below zero.
When the ambient temperature is below 32ºF / 0°C, the charging current will flow to heating film to warm up the battery first, and switch to normal charging when the battery internal temperature raises up to 32ºF / 0°C.
