I noticed that, at least with my unit, the Battery Meter only functions correctly when using Sleep Mode. When using Shutdown Mode, it does not reflect the actual battery charge.

I like to do a full charge via the wall outlet when the Battery Meter drops from 4 bars to 1 bar. I ran 4 cycles so far. The first 2 cycles were done using Sleep Mode and lasted 16 days for the first cycle and 18 days for the second cycle.

On the third cycle I used only Shutdown Mode and the battery lasted 46 days and then required a Reset to revive it. The Battery Meter stayed at 4 bars throughout the cycle right down to where the Reset was required.

On the fourth cycle I used Shutdown Mode for 30 days and then used Sleep Mode for the last 11 days. At the end of the 30 days the Battery Meter stayed at 4 bars. During the last 11 days it dropped gradually to one bar at which time I applied a 2 hour charge using the wall outlet.

Thus, it appears the best way to maximize the battery life without being forced to use a Reset at the end is to use Shutdown Mode for 30 days and then switch to Sleep Mode for the remaining battery life.
