An excellent way to deliberately reduce the life of the battery. A lead-acid battery must be taken to a higher voltage for a minimum period of time, until the current tapers off and can then be maintained at 13.5 volts. The 13.5 volt float voltage must be temperature compensated.
Therefore, in cyclic applications where the discharge rate is often greater than 0.1C, a lower rated lithium battery will often have a higher actual capacity than the comparable lead acid battery. This means that at the same capacity rating, the lithium will cost more ...
The 24V lead-acid battery state of charge voltage ranges from 25.46V (100% capacity) to 22.72V (0% capacity). The 48V lead-acid battery state of charge voltage ranges from 50.92 (100% capacity) to 45.44V (0% capacity). It is important to note that the voltage
This buildup can reduce the battery''s capacity to hold a charge, increase internal resistance, and eventually lead to battery failure. Lead Acid Battery Sulfation Is One Of The Leading Causes of Battery Failure. Several factors can contribute to the formation of harmful lead sulfate crystals on battery plates. The most common causes include:
Introduction of carbon materials to the negative electrodes of LAB could suppress sulfation problem and enhance the battery performance efficiently. This paper will attempt here …
@Ann Yes, if its a lead acid battery there should be permanent damage if you stored it for two years and never charged it. As you can see, all lead acid battery have a natural discharge rate between 1% to 20% monthly, so at 20% monthly your battery would be 100% discharged in just 5 months and that is using the worst case scenario discharge rate, at the …
