Once the charger is attached to a sealed lead acid battery and plugged in, the charging process will begin. The charger will subject the lead acid battery to three steps of charging.
In the first step, the charger will enter into 'boost' mode. During this step, the charger is in constant current mode with the current rate remaining at its maximum value (note- the battery voltage is lower than the switching level of the timer).
In step two, the battery will be nominally 80-95% charged, and the charger will switch into time controlled/ constant voltage mode (current is no longer being provided at its maximum rate). The charger will continue to provide a constant voltage until the time interval is completed.
The third and final step will place the charger in float/standby mode as the battery will be fully charged. Because the charge voltage is at a standby level, the charger can continue to be connected to the battery. Should the battery be used, the charger can return to rapid charging (step 1).
Note: The Prices include CORDSETS and adapters. Please call / specify the country this will be used in for us to send an appropriate cord. If no country is specified, we assume that it is for North America.
(Please mention the voltage and Amp Hour ( Ah) rating and or the watt hour (Wh) rating of the battery pack the charger will be used for while you place your order)
