This is due to the fact that the nominal voltage for lead acid batteries is 2 V/cell while real-world OCV values for 100 % SOC are in the 2.25 .. 2.35 V. Fully charged voltage: see above. Depends on cell chemistry details. More important: do not exceed 2.4 V (lower values for sealed batteries) during charging as this will damage the battery.
This article describes the technical specifications parameters of lead-acid batteries. This article uses the Eastman Tall Tubular Conventional Battery (lead-acid) specifications as an example. Battery Specified Capacity Test @ 27 °C and 10.5V The most important aspect of a battery is its C-rating.
Proper temperature management, such as insulation or ventilation during cold storage or hot operation, would ensure optimum lead acid battery performance and prolong its operational life. 11. JIS Standard
Lead-acid batteries are highly sensitive to temperature. Testing should ideally be conducted at room temperature to ensure accurate results. Extremely high or low temperatures can skew the results of voltage, capacity, and resistance tests. To ensure optimal performance, it is recommended to perform battery testing at regular intervals.
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.
Batteries delivering above 80% are generally still in good condition, though they should be monitored for any decline. Capacity testing is one of the most reliable methods for evaluating the true health of a lead-acid battery. However, it can be time-consuming, as the battery must be fully discharged and then recharged. 3.
