I wasn't clear. 

battery.runtime.low is not a counter, but a value estimated in seconds that is decreasing conforming the battery is discharging. It's mean: How much time (in seconds) will be necessary until the battery achieve the depleted status ( http://www.networkupstools.org/protocols/sec.html#Estimated_Minutes ) . If the UPS don't have a load, this value will be higher than the value when the UPS have 100% of load. 

The battery.run.low is not related with battery.runtime this is important explain. Battery.runtime will count in seconds (http://www.networkupstools.org/protocols/sec.html#Seconds_on_Battery) how much time the UPS is in the Battery status and doesn't depend of load or other parameter as battery.run.low depends.

battery.run.low is a dynamic timer, initially without a load in UPS it will be a high seconds estimator. It will change dynamically conforms I can increase the UPS load or not. It's a value calculated from the UPS to notice the User how much time he have until the UPs battery achieve the depleted status.

The battery.run.low can be higher than battery.runtime, do you agree?

I admit that the documentation is not clear that battery.runtime.low should be a configuration value, rather than a counter.

However, I am still confused as to why the runtime.low number is larger than runtime (which would be the time until the battery is completely empty, versus just low).

Since this might be hard to work around with the current driver, we can put a note in the DDL, but at this point I don't know what the note should say.
