Frequently Asked Questions

  • How do you know the batteries are fully charged?
    • The charger has four independent smart charging slots, that show bar levels as the status of the battery. When a battery is fully charged, the corresponding battery capacity indicator will be full.
  • What charger is best for me?
    • The best charger for your battery depends on the type of battery you want to charge and your budget.

      TN299 charger would be best for you if you need to charge both Li-ion/LiFe batteries (size 18650/14500/10440) and NiMH/NiCd batteries. This charger is versatile and can handle multiple battery types.

      If you only need to charge NiMH/NiCd batteries and also require a discharging function, then the T9688 charger would be best for you. This charger is specifically designed for NiMH/NiCd batteries and includes a discharge function to help prolong the life of your batteries.
  • Will TN299 charge 3.0V RCR123A battery?
    • Unfortunately, no. This charger is only compatible with the following:
      NiMH/NiCd: AAA, AA, C, D, & 9V
      Li-ion/LiFePO4: 18650, 14500, 10400
  • Can I charge AA and AAA batteries at the same time?
    • Yes. The Tenergy chargers in this listing have individual charging slots and customer can charge both sizes at the same time, and there is no need to charge in pairs.
  • How long does it take to charge NiMH/NiCD batteries?
    • The estimated charging time will mostly depend on the charger's charging current and the capacity of the battery.

      To calculate the estimated charging time, divide the battery capacity(mAh) by the charging current(mA). Ex. 2500mAh / 500mA = 5 hours
  • Can I charge Li-ion 1.5V AA/14500 battery on TN299 charger?
    • No, a special charger compatible with Li-ion 1.5V is required for the Li-ion AA/14500 battery, as it cannot be charged using a regular charger.
