LEAD ACID BATTERIES : 5.1 The batteries shall be made of closed type lead acid cells of very low internal resistance having high cycling capability ,moderate size, high service life minimum 20 years, excellent performance for both low & high rates of discharge, rigid cell plates design type manufactured to conform to
The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
In order to achieve the optimum service life for vented lead acid batteries on float charge, a maximum effective value of the alternating current of 2 A per 100 Ah battery capacity (C 10) is recommended. Every lead acid battery decomposes certain amounts of water into hydrogen and oxygen gas.
1. Construction of sealed lead acid batteries Positive plate: Pasting the lead paste onto the grid, and transforming the paste with curing and formation processes to lead dioxide active material. The grid is made of Pb-Ca alloy, and the lead paste is a mixture of lead oxide and sulfuric acid.
The recommended operating temperature for lead-acid batteries is between 10 °C and 30 °C. Technical data is valid for the nominal temperature of 20 °C. The ideal operating temperature range is 20 °C ± 5 K. Higher temperatures shorten the service life of the battery. Lower temperatures decre-ase battery capacity.
Lead acid batteries loose capacity with decreasing temperature and vice versa, as shown in fig. 7-6. This should be considered when sizing the battery. As corrosion processes in lead acid batteries are significantly depending on battery temperature, the battery service life time is directly related to the ambient temperature.
