Notes:
Seamless switch between AC and battery.12V and 5V won’t turn off during the switch.
The battery voltage lower than 1V won’t impact 12V,5V output if there’s AC input. Charging LED won’t light on.
The battery voltage corresponding to the battery capacity linearly. 11V corresponding to 1.2-1.8V, 11.5V corresponding to 1.7-2.3V, 12V corresponding to 2.2-2.8V, 12.5V corresponding to 2.7-3.3V

Notes:
Criterion A: Normal performance during and after test.
Criterion B: Low-voltage protection or reset is not allowed. Temporary output voltage fluctuation ceases after disturbances ceases, and from which the EUT recovers its normal performance automatically. During the system test, output voltage fluctuation or reset is not allowed too.
Criterion C: Temporary loss of output is allowed, but the hardware can’t be damaged. The EUT recovers its normal performance automatically or operator intervention.
Criterion R: Loss of output which is not recoverable is allowed. The primary protective component (fuse) can be damaged. The EUT recovers its normal performance after replace the damaged component.
