Why choose an EarthX lithium battery?   S.P.E.E.D

  • S = SPEEDY CHARGING- EarthX ETZ batteries will charge 2-3X faster than a lead acid battery.
  • P = POWERFUL and LONG LASTING- EarthX ETZ batteries crank your engine over easily and will improve your starting performance as their resting voltage is 13.3V compared to a lead acid which is only 12.6V. Also EarthX ETZ batteries life span is much longer than a lead acid battery and can last years longer!
  • E = EXTREMELY LIGHT WEIGHT- EarthX ETZ batteries are up to 80 percent lighter than their lead acid equivalents. Lighter weight = better performance! This saves an average of 2-3 lbs. for dirt bikes, 6-8 lbs. for street bikes and 10-20 lbs. for touring and cruiser bikes.
  • E = ENVIRONMENTALLY FRIENDLY- EarthX ETZ batteries are environmentally and user friendly. Nonhazardous, nontoxic, nonpoisonous. Will not sulfate, will not corrode, will not freeze, will not boil over, will never need water added and will not spill acid EVER!
  • D = DISCHARGE RATE- EarthX ETZ batteries have a much slower discharge rate than a lead acid and the need to charge them is greatly reduced.


What is the difference between the ETX18C and the ETZ14C?

 The ETX18C has 230CCA, 340PCA; weighs 2.2 pounds; has 6.2Ah capacity and has the full battery management system with a 1 year warranty.

The ETZ14C has 330CCA, 690PCA; weighs 2.5 pounds; has 6.8Ah capacity and has the battery management system minus over discharge protection and excessive cranking protection so it will not cut off in cold weather starts with a 1 year warranty. This battery was designed for high cranking amps in the cold.

They are both the exact same physical size.
