This HAT board is completely USELESS as UPS: when you switch the main power off (simulating a black out), the battery starts discharging (ok), but when you switch the main power on again (e.g. black out is over), the battery keeps on discharging. For a correct recharge of the battery after the main power returns, you have to: 1 - safely shutdown the Raspberry 2 - manually switch off the UPS HAT button 3 - manually switch on the UPS HAT button In practice, the man must be in the loop each time a black out (or a power surge) occurs...
