Hours/cycles remaining chart

There are numerous factors that affect a battery’s service life that make the Estimated hours/cycles remaining chart less of a definitive calculation of when a battery is spent and more a decision making tool.

  • The Estimated temperature corrected remaining hours/cycles chart is based on the expectation that a battery made up of 2 volt cells with 11 or more plates will last for approximately 1500 6 hour cycles or approximately 9000 hours of battery life.
  • 2 volt cells with 9 plates or less and 6, 8 and 12 volt batteries have a lower life expectancy of approximately 300 5 hours cycles or approximately 1500 hours of battery life.
  • If your battery is showing negative hours remaining it is an indication that the battery has out-performed it’s expected service life.
  • It does not mean that the battery should be replaced immediately.
  • If the battery is still performing the work required of it it can remain in service until it is noticed that it is having difficulty keeping up to it’s work load.
  • Once the battery is having trouble performing the work required of it your decision to repair or replace is simplified as you have received warning in advance of it’s impending failure.
  • If regular battery inspections are performed and they indicate that there is only 1 or 2 problem cells while the rest of the cells remain consistent cell replacements could be considered to extend the life of the battery.
