Oops. I forgot to set the battery pack for weekend running. Now it gets to recharge.
It finally hit 3 cycles, after 23 days and change. Used as I am, this pack should be good for 7500-15000 cycles. It takes more than a week for a cycle at this pace. Ergo, this pack (not taking into account utility company power failures, leading to longer times running off of batteries), should last somewhere between 150 and 300 years, assuming the batteries don't need hip replacements by then.
