Charging LiFePO4 Batteries

Charging LiFePO4 batteries requires the use of a battery charger that does not have a "desulfation" or "pulse" mode. These batteries require the use of a battery charger specifically developed for charging LiFePO4 batteries. Luckily, with the evolution of lithium batteries in starting and cycling applications there are many options. We highly recommend Battery Tender or NOCO LiFePO4 compatiable battery chargers. 

Off-Season Storage Recommendations

While storing your power sports vehicle recommend the following:

  1. Store your battery in a cool, dry place. (Heat causes your battery to discharge at a faster rate.)
  2. Never allow your battery to remain in a discharged condition for a long period of time. When your battery is to be stored, it should first be fully charged. Recharge your battery approximately once every two months, or when the specific gravity of the electrolyte drops to 1.225.
  3. Do not overcharge your battery. This will cause damage to the cell plates. When charging your battery, feel the sides of the battery container from time to time. When the battery is warm, is has an adequate charge. The specific gravity of a fully charged battery is 1.265.
  4. Never allow the battery to freeze.
  5. As a battery gives off flammable hydrogen gasses when it is charging, never bring an open flame near a battery. Always charge your battery in a well-ventilated area.

To extend the life of your battery we recommend using a battery maintainer. A battery maintainer will safely keep the battery fully charged while in off-season long term storage.
