Set Battery Current Limit
Consult battery manufacturer’s data for maximum battery recharge current
settings.
The Battery Current Limit is set as a percentage of the 10-hour rate entered
above.
It is recommended this value is set at the highest rate allowable to ensure the
battery is recharged as fast as possible.
In some systems, especially larger systems, this may require limiting further
because of the number of rectifiers available, rather than the maximum
setting.

For telecom settings, this limit is often set to 10% (or 0.1C10, i.e., a 10A current limit
for a 100Ahr battery). This is more typical of a design parameter than the need for the
setting to be at this level but a setting higher than this level should be considered to
enable the fastest recharge possible without exceeding the battery manufacturer’s
maximum value.
Ensure sufficient rectifier capacity is available to cover battery recharge and load
requirements.
