Methinks that depleting the battery to 10 is a very severe wear on it. I would go for 50% tops. If the system is not capable of going down fast...
If you try to power down my machine at 23:50 hours, it will not go down till 00:15, or worse, 00:30. Other times, yes, it will go down fast.
Eh..., Normally I agree, but here you are just handling the power fail case. I always get to my machines and shut them down before they reach 10%. Only time they exhaust the battery to 10% is if the office goes down at night -- and well, that's what the $25 batteries are supposed to do. Regardless of the number of discharges, I always get 3-5 years out of the batteries. I have a separate UPS that only powers the cable modem and wireless router, I will let go to the 10% for any outage that lasts that long. Generally gives about 2.5 hours of runtime. Setting at 50% would be fine, that would just shorten the runtime to power off. Whatever you set it at is fine -- just make sure it is set :) -- David C. Rankin, J.D.,P.E.
