For Telecom applications, the 10-hour rate is usually the name-plate rating of the
battery. However, once again, check the battery manufacturer's data sheets as some
manufacturers state the 20-hour rate (which is usually a little more "optimistic").
The second rate is required specifically for the time-remaining algorithm. A 4-hour
rate is usually a good one to use. This information is available from the battery
manufacturer's data sheet.
The Battery SoC adjust can be used at the time of installation (or for testing purposes)
in case the installed battery is not initially fully charged. If you think the battery is only
80% charged, then simply enter that value. The value displayed here will correct itself
once the battery has been on charge for some time or gone through a few
charge/discharge cycles.
Battery Recharge Efficiency considers the ohmic and any other losses in the battery
charge/discharge cycle. The effect is that more energy (Ah) needs to be put back into
the battery than was taken out. With the efficiency set to 96%, then 4% more Ah is
needed to be returned to the battery before the EM4x will register that the battery is
at 100% SoC (State of Charge).
The Battery Discharge Threshold is a buffer to prevent false triggering of discharge
notification and is usually related to the size of the battery shunt. A larger shunt
requires a larger discharge threshold.
