Many similar batteries only have a cycle life of about 2,000 cycles. The 3.2V 60Ah and 100Ah Lithium Batteries each have a cycle life of over 3,000 cycles. Price breaks are available for these batteries starting at 16 each. See complete pricing and specifications by following the links above.
What is the Life Expectancy
of the Aluminum Batteries?
- Factor 1: Depth of Discharge…Percentage
of Capacity Used Per Cycle.
- DOD, short for the Depth of Discharge, is
used to describe how deeply the battery is discharged. If we say a battery is
100% fully charged, it means the DOD of this battery is 0%, If we say the
battery have delivered 30% of its energy, here are 70% energy reserved, we say
the DOD of this battery is 30%.
- Factor 2: Discharge Rate, The AMPS
Divided by the Capacity
- To Read the Chart Above, here are Some
Examples
A. All Numbers are at a 1C Discharge Rate, which
is Aggressive…
B. At a 90% Depth of Discharge, Our Batteries
Will Provide 2400 Cycle to 80% State-of-Original-Capacity (SOIC)
C. At a 10% Depth of Discharge (Say, Engine
Starting) Our Batteries Will Provide 35,000 Cycles Until 80% SOIC. Beyond
35,000 Cycles the Battery is Still Functioning but Gradually Losing Capacity,
but not Performance
Conclusion: By recharging a
lithium battery more frequently, thus reducing the DOD (depth of discharge),
the battery cycle life is Increased. Solar is very often a beneficial method to
reduce DOD and increase life!
