(English) UMS4 User Manual
Automatic Battery Internal Resistance Detection
When the UMS4 is on and the battery is installed, it will automatically detect and display
the Internal Resistance below the "CHG. STATUS". When the Internal Resistance is below
250mΩ, it will show "Good" on the screen. When it is above 250mΩ, it will show "Poor"
on the screen to indicate that the battery should be replaced.
Charged Volume Calculation
During the charging process, the system will automatically calculate and display the
Charged Volume below the "CHG. STATUS".
Anti-short Circuiting and Reverse Polarity Protection
If there are batteries inserted with polar reversed or short-circuited, the screen will flash
to show "EE EE".
Energy Saving Function
If there is no action to the buttons or batteries in 3 minutes, the screen will automatically
go dim to save energy. Perform any action to light up the screen.
Over-Discharged Li-ion Battery Activation
The UMS4 is capable of activating over-discharged Li-ion batteries with a protective
circuit. After battery installation, UMS4 will test and activate the battery before charging.
When a battery is detected as damaged, the screen will show "EE EE".
Over-Discharged IMR Battery Restoration
When an over-discharged IMR battery is inserted, the screen will show "EE EE". In
this case, long press the V button to enter Restoration Mode. After that, the charging
process will continue. The battery should be replaced if it fails to be restored after several
attempts.
NOTE: When attempting to restore an IMR battery, reverse polarity protection is
temporarily disabled. Please ensure batteries are correctly inserted. Failing to do so may
result in fire or explosion.
Overtime Charging Protection
The UMS4 will separately calculate the charging time of each battery. When the charging
time exceeds 20 hours in one slot, it will automatically cease the charging process of this
slot and display "END" below the "CHG. STATUS". This is to prevent possible overheat or
even explosion due to battery quality issue.
Precautions
1. The charger is restricted to charging Li-ion, IMR, LiFePO4, Ni-MH/Ni-Cd rechargeable
