But before we dive into SLA batteries, we need to understand what lead-acid batteries are. Lead-acid batteries, at their core, are rechargeable devices that utilize a chemical reaction between lead plates and sulfuric acid to generate electrical energy. These batteries are known for their reliability, cost-effectiveness, and ability to deliver
During the float charging stage, the voltage is typically set around 2.25 to 2.27 volts per cell, which amounts to about 13.5 to 13.8 volts for a 12-volt battery. This voltage level is sufficient to counteract self-discharge, keeping the battery topped up without causing excess gassing or water loss.

The use of instruments to directly or indirectly measure the internal resistance of the valve-regulated lead-acid (VRLA) cell has dramatically increased in recent years. There is a desire to establish a technique to determine the state-of-health of the battery in an attempt to improve the reliability and service life of the battery system. The
For example, a lead-acid battery with an internal resistance of 20 milliohms or above is considered bad. Similarly, a lithium-ion battery with an internal resistance over 250 milliohms is considered bad. Conclusion. Understanding battery internal resistance is crucial for determining the overall health and performance of a battery. By using a battery internal resistance chart,

State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature. The FCC is derived from the maximum chemical capacity of the fully charged battery Q MAX and the battery impedance R DC (see Fig. 1) .
Three common SoC monitoring methods – voltage correlation, current integration, and Impedance Track are discussed. State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature.
R DC must be compensated for a discharge current and temperature. Texas Instruments uses the Impedance Track method to determine SoC of lead acid batteries . While current off, the OCV is measured, which is used to determine the SoC and to update Q MAX. When discharging, both discharge current and voltage are measured.
Lead-acid batteries naturally degrade as they age. One effect of this deterioration is the increase in resistance of the various paths of conductance of the internal cell element. The internal ohmic test units are generally designed to detect this internal change.
When the battery is in idle mode, the SoC is determined by the battery voltage and the predefined table of the OCV/SoC relationship, which is temperature-compensated. Instead of a table, it is possible to use a suitable mathematical function describing this dependence obtained by regression analysis.
There were variations in the internal ohmic readings that were unrelated to the test variables. Based on the preliminary results of this study, it is recommended that internal ohmic readings not be used as the sole acceptance criteria for lead-acid batteries.
