MB/TS25 PC211 UPGRADE Battery Charger
Operators Manual
4.3 CHARGING BATTERIES
To keep batteries in good condition it is important that correct charging procedures
are observed.
The TS25 UPGRADE is an important tool in ensuring the its flexibility allows the user to
choose charge processes that are best suited to the battery. The TS25 UPGRADE has
two inbuilt charging processes that suite a wide range of batteries.
The use of constant voltage charging is best suited to lead acid types of batteries and
the TS25 UPGRADE controls constant voltage charging to ensure that no excess of
current can be driven into the batteries causing it damage.
Constant voltage charging is achieved by inserting a maximum specified current into a
battery until its terminal voltage reached the voltage set point. Once this voltage set
point has been reached the unit will reduce the current injected to maintain the
voltage set point. The charging process will continue until the charge time has
elapsed.
Constant current charging is employed mainly for Nickel Cadmium and Nickel Metal
hydride types if batteries, where a constant current can be driven into a battery for a
specified time and parameters can be set to prevent over charging.
Constant current charging is achieved by the unit driving a specified constant current
into the battery for a specified amount of time. During this time it will monitor the
battery voltage and auto terminate the process if this voltage is reached. This voltage
set point can be either the rise point of the battery or can be used as an over-voltage
parameter.
The TS25 UPGRADE has a new charge mode implemented, which is more suitable to
alkaline batteries. In this mode known as Constant Current Plus mode the unit will
drive the constant current into the battery until the voltage set point is reached. Once
this point is reached the unit will continue charging at the same current for the time
specified.
4.3.1 MANUAL CHARGING
The unit required four parameters to perform a constant voltage charge. These
are: -
Maximum charge current (Amperes).
Charge time or charge additional time (Hours).
Voltage set point (Volts).
Charge mode.
To program these values the unit needs to powered and not performing either a
capacity test or charge on the channel to be used.
