  4. Turn your batteries off when you go inside for a break or lunch.

  10. If storing over the summer, we recommend charging in July.

Important things to know about Therm IC Batteries:

  1. The Max and SuperMax batteries will not work at peak performance during their first use or after prolong storage. 2-3 charging and discharging cycles are required to get them to full operating capacity.
  2. SuperMax chargers may turn off prematurely during the first charging cycle after prolong storage because the batteries will not yet be capable of being fully charged. In this case, disconnect the battery pack from the charger and reconnect it.
