Warranty Details
2. Inserting Battery: Insert a battery as instructed. An incorrectly inserted battery will prevent the UM10 from
3. Battery Test: After battery installation, the UM10 will run a quick battery test before charging. If a problem
is detected (for example the battery is installed backwards), the UM10 will terminate the charging
process and stay in standby mode to notify the user.
4. Charging: During the charging process, charging current will adjust automatically based on the detected
battery type, power level and internal battery resistance. For example, when charging batteries of smaller
capacities such as 14500 and 16340, charging current will automatically be set to 500mA, ensuring safe
use and preserving battery longevity.
5. Charging Progress: The UM10 will indicate battery status and charging progress. When the battery is
fully charged, 5 power level indicator bars and “100%” will illuminate steadily on the LCD display.

Worldwide Warranty Service
When there is a power deficit for the UM10 to charge both the battery and USB device simultaneously, the
UM10 will prioritize the charging of the battery or the device following the user’s preference.
When the top switch is set to BATTERY, battery priority mode will be activated. In this mode, the UM10 will
charge the battery first. When the battery is fully charged or removed, the UM10 will then charge / power
the USB device automatically.
When the top switch is set to USB, USB priority mode will be activated. In this mode, the UM10 will charge /
power the USB device first. When the USB device is fully charged or disconnected, the UM10 will charge
the battery automatically.
NOTE: A small electrical current will keep passing through to the external device connected to maintain the
device in its full power state when it is charged.
The UM10 is capable of activating over discharged protected Li-ion batteries. After battery installation, the
UM10 will test and activate the batteries before charging. Batteries detected as damaged cannot be
activated by the UM10 and “EE” will be displayed on the LCD to indicate an error.
NOTE: Nitecore does not recommend charging zero volt (0V) (over discharged) unprotected Li-ion batteries
with the UM10 and doing so can result in battery leakage fire, or explosion.
1. Nitecore recommends using only quality USB adapters with the UM10. Using poor quality adaptors may
result in the LCD displaying “EE” to indicate an error.
2. The charger is restricted to charging Li-ion, IMR rechargeable batteries only. Never use the charger with
other types of batteries as this could result in battery explosion, cracking or leaking, causing property
damage and/or personal injury.
3. The safe operation temperature for the charger is between -10 to 40°C, and the safe storage
