Nice one Robert...Interesting but wrong! Deep discharge is damaging to Li-ion batteries, doing one every few months will reduce the life of the battery. Pressing that Cal button on the MH22 results in a deep discharge, don't press Cal unless the Cal light illuminates.
Tripped over this site about Charging :
http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table
Mentions that when Fuel-gauge becomes " erratic "Li-ion`s do need to Discharg/Refresh every 1- 3 month .
When recharging I always press the Refresh button on the MH-22 , so far so good ,but I`m beginning to have doubts now.
Before relying on internet information, READ THE MANUAL for the device, the manufacturer really does know how best to use its products.
