Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems) With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge.
This mode works well for installations that do not draw a load when on standby. Lead acid batteries must always be stored in a charged state. A topping charge should be applied every 6 months to prevent the voltage from dropping below 2.05V/cell and causing the battery to sulfate. With AGM, these requirements can be relaxed.
When installing a lead-acid battery, insulation measures shall be taken for the tools which are being used. When connecting, connect the electrical appliances other than the battery first, ensure there is no short circuit, and finally connect the battery.
The chaining current is kept constant throughout the charging period by reducing the resistance in the circuit as the battery voltage goes up. This method is usually employed for initial charging of lead-acid batteries and for charging portable batteries in general.
