SmartUPS C1000 code L.01 on display

[MikeInMA]

I have a SmartUPS C1000 that is displaying code L.01 on the front panel - the UPS seems to be working normally otherwise.  What does this code mean - I cannot find reference to it in the owners manual or in my online searches.

Thanks

The owner's manual says the meaning of this code is "LifeTimeNearEnd". What I don't know is, does this refer to the batteries or the unit as a whole.

This refers to the battery

I have replaced the battery and the code is still there. Is there anyway to reset unit after battery has been changed?
