Battery Charging

Charging batteries properly requires administering the right amount of current at the right voltage. Most charging equipment automatically regulates these values. Some chargers allow the user to set these values.

In either case the original instructions for your charging equipment should also be referenced for proper charging. Here is list of helpful items to remember when charging.

  • Become familiar with and follow the instructions issued by the charger manufacturer.
  • Batteries should be charged after each period of use.
  • Lead acid batteries do not develop a memory and need not be fully discharged before recharging.
  • Charge only in well-ventilated area. Keep sparks or flames away from a charging battery.
  • Verify charger voltage settings are correct.
  • Check water level (see the Watering section).
  • Tighten all vent caps before charging.
  • Prevent overcharging the batteries. Overcharging causes excessive gassing (water breakdown), heat buildup, and battery aging.
  • Prevent undercharging the batteries. Undercharging causes stratification.
  • Do not charge a frozen battery.
  • Avoid charging at temperatures above 120 degrees F.

Proper Charging

  • Verify charger condition by plugging into the wall receptacle and by inserting the charger handle into the car. LED lights will flash red or green (Powerwise QE) or the ammeter will indicate 21 amps (Powerwise 1&2) based on depth of discharge.
  • Allow the charger to complete the charge process by turning off on it’s own.
  • Short charging will promote unbalanced batteries and needless battery replacement.
  • Equalization charges are recommended monthly. Equalization is an overcharge performed on flooded lead-acid batteries after they have been fully charged. It helps eliminate stratification and sulfation, two conditions that can reduce the overall performance of a battery.

Visual LED Display Information

LED Operation Codes:
SHORT LED flash green = less than 80% charged
LONG LED flash green = more than 80% charged
SOLID LED green = 100% charged
RED LED flash = fault code
