Maximum Charge Voltage (SLA and Li-ion only)
The Maximum Charge Voltage parameter defines the voltage threshold of SLA and
Li-ion batteries that must be maintained until the End of Charge conditions are
reached. The charge current drops while the maximum charge voltage is
maintained.
Available settings: 2.20 – 2.65V/cell (SLA); 3.90 – 4.35V/cell (Li-ion); 3.40 –
3.85V/cell (Li-Ph)
Default Max. Charge Voltage: SLA: 2.40V/cell; Li-ion: 4.2V/cell; Li-Ph 3.60V/cell
Refer to the manufacturer’s specifications for proper settings as these values vary
depending on the charge rate used and the ambient temperature.
End of Charge (SLA and Li-ion only)
The End of Charge parameter defines the rate of charge the analyzer uses to
determine if the battery is fully charged. When the charge current drops below the
End of Charge setting while maintaining the Maximum Charge Voltage, the battery
is considered fully charged. Refer to the manufacturers specification for proper
setting as these values vary depending on the charge rate being used. For some
batteries, a lower setting is required to ensure adequate charge.
The Charge Optimization setting affects the way the end-of-charge setting is used
during a charge (see
Optimizing Charge Time or Capacity
, page 79).
Available settings: 0.01 C – 0.10 C
Default: SLA and Li-ion: 0.05C.
Default: Li-Ph: 0.03C
