For example a 26Ah lead acid battery (20 hour discharge rate) is approximately only 22Ah at the 5 hour discharge rate. Low weight - approximately one third of a similar capacity lead acid battery. Deep cycle - recharges up to 2000 times at 80% depth of discharge.
So, there are mainly a few key performance indicators that are important on battery day: C-Rate/ Charging rates of the batteries (This key figure is currently still important, but is becoming increasingly unimportant. The cheaper and more energy-tight batteries become, the less important a high charging capacity will be.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
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. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.
However, due to the corrosive nature the elecrolyte, all batteries to some extent introduce an additional maintenance component into a PV system. Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%.
The results show better performance with different discharging rates. The cyclic performance of the battery was carried out at different discharge rates. In the performance assessment, state of charge (SOC) have been estimated and correlated with coulomb counting method which resulted in close agreement.

discharge indicators - The discharge indicator should be protected from manipulation, i.e. the unplugging of the battery must not lead to a reset of the discharge indicator. -The deep discharge signalling respectively shut-off of the lifting for counterbalance trucks at a depth of discharge of 80 % must be given in any case.

A lead-acid battery is a type of rechargeable battery that stores electrical energy through a chemical reaction between lead oxide and sulfuric acid. This battery comprises two lead plates immersed in an electrolyte solution, which facilitates the movement of ions, enabling energy storage and discharge.
The solubility of lead in battery acid is very approximately 4 parts per million. The charge-discharge and discharge-charge reactions proceed regardless of lead''s low solubility because lead is able to move around quite easily across the surface formations of the electrodes.
Regularly discharging a lead acid battery below 50% can lead to sulfation, which decreases performance and capacity. The Society of Automotive Engineers (SAE) defines sulfation as the formation of lead sulfate crystals during discharge, which can harden over time and become difficult to reverse.
