Customer ServiceCharging lead acid batteries in cold weather requires special consideration. A higher charge voltage is needed at low temperatures.
The charging method is another key procedure in any test specification. Most documents follow the approach that it shall be ensured that the lead–acid battery is completely charged after each single test. The goal is that the testing results are not influenced by an insufficient state-of-charge of the battery.
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.
Initial performance parameters are the key properties of a lead–acid starter battery. These are the total energy or capacity content and the ability to be discharged with a high current at low temperatures to start an internal combustion engine.
Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
In the case of a lead-antimony battery, measure and record the specific gravity of 10% of the cells and float charging current.
