Charging
KiloVault 2100 PLC batteries are usually charged using a three-stage charging cycle: bulk,
absorption, and float stages. Bulk is a constant-current stage. The purpose of the bulk stage is to
raise the battery voltage to a relatively high level with an initial fast charge. Absorption is a
constant voltage stage. It is established upon reaching the absorb voltage settings. The battery
is considered to be full when the following conditions are met: The charge current must taper
down to a level between 1% and 2% of the total battery amp-hours while maintaining the
absorption voltage. The charger can then exit absorption and then enter the float stage. The
float stage is a maintenance stage which ensures the battery remains fully charged.
