3.6 Discharge the batteries

1) When the UPS is in battery mode, the buzzer will beep according to

different battery level. If the battery level is normal, the buzzer will

beep once every 4 seconds; If the battery voltage drops to the

alarming level, the buzzer will beep hurry (once every sec) to

remind the user that the battery is low level and the UPS will be

shutdown automatically soon. The user could switch off some

non-critical loads to avoid the shutdown alarming and prolong the

backup time. If have no more load to be switched off at that time,

you have to shutdown all loads as soon as possible to protect the

loads or save data. Otherwise there is the risk of data loss or load

failure.

2) In battery mode if the user don’t like the buzzer noise, the beep

could be muted by short-press the button.

3) The backup time of the long backup time model is dependent on the

external battery capacity except the load capacity mainly.

4) The backup time may vary from different environment temperature

and load type.

3.7 Test the batteries

1) If you need to check the battery level or aging status when the UPS

is running on normal mode (line mode), you could short-press the

button to let the UPS transfer to battery test mode.

2) To make the system more reliable, the UPS will perform the battery

test automatically periodically. The default period is once per week.

4) If the UPS enter the battery test mode, the display and buzzer

indication will be the same as the battery mode except that the

Battery icon is flashing and the mains icon lighten constantly. So you

can check the battery level at this mode.
