This guide to IEC/EN standards aims to increase the awareness, understanding and use of valve regulated lead-acid batteries for stationary applications and to provide the ‘user’ with guidance in the preparation of a Purchasing Specification.
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
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.
The charging voltage for the valve regulated lead acid battery should not be in excess of the gassing voltage, which is 2.4~2.5V/cell. The gassing voltage varies with temperature, and is decreased as the temperature is increased. Its temperature coefficient is –5.0mV/°C/cell.
Batteries after long period storage will lose some capacity due to self-discharge, and need recharge to restore its full performance. Do not put sealed lead acid batteries in airtight containers, or install the batteries in a room without ventilation.
Thisstandard was first published in1960, superseding IS 541 :1954. The standard prescribed the dimensions, capacities andperformance requirements of stationary cells and batteries of lead-acid type with plante positive plates.
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service …
