What happens if you keep a lead acid battery in discharge?
If a Lead Acid battery is kept in a discharged state for a long period of time, it will increase the speed of the sulphation. The sulphation refers to the deposit of Lead Sulphate on the plates of the Lead Acid battery. This will cause the battery to be irreversibly damaged and thus will end up getting wasted and unusable.
Should I use a lead acid or a lithium-ion battery?
Both lead acid and lithium-ion batteries can be effective options for a battery backup system. However, it's usually the right decision to install a lithium-ion battery given the many advantages of the technology, such as longer lifetime, higher efficiencies, and higher energy density.
Why is a lead acid battery still widely used?
Lead-Acid batteries are still widely used due to their features, such as: Each cell can be checked for charge status using a hydrometer, cell tester, or multimeter. The electrolyte level can also be maintained by adding distilled water.
How long does a deep-cycle lead acid battery last?
A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery.
