Product information

Description

The Nitecore UM4 battery charger is a compact household charger designed to handle multiple common battery chemistries, including Lithium Iron Phosphate (LiFePO4), Lithium‑Ion (Li‑ion) and Nickel‑Cadmium (Ni‑Cd). It accepts a DC input of 9V and provides an output voltage of 4.35V per charging channel, and supports simultaneous charging of up to four batteries. Compatible battery sizes include AA, AAA, AAAA, C and D. The unit's black finish and slim profile are suited to everyday home use and storage.

Advantages

The UM4 provides multi-chemistry support, allowing the same charger to service LiFePO4, Li‑ion and Ni‑Cd cells. With four charging slots it enables parallel charging of several batteries, reducing waiting time. The charger’s DC input and standardized 4.35V output simplify integration with common DC power sources. Compact dimensions and a discreet black colour make it convenient to place on a shelf or in a drawer without occupying much space.

Suitable for (tasks / use cases)

Charging AA and AAA rechargeable batteries for household devices such as remotes, toys and clocks
Refreshing AAAA, C and D rechargeable cells used in flashlights, radios and portable equipment
Maintaining a small set of spare Li‑ion or LiFePO4 batteries for hobby electronics

How to use

Insert rechargeable batteries into the appropriate slots respecting polarity markings. Connect a compatible 9V DC power source to the charger, then switch the unit on if a power control is present. Monitor charging status as indicated by the charger's built‑in indicators and remove batteries once charging is complete. For mixed battery sizes, place each battery in its own correctly sized slot and avoid charging non‑rechargeable cells.

Usage recommendations

Use only rechargeable batteries of the supported chemistries and sizes. Ensure the DC power adapter supplies the required 9V and is compatible with the charger connector. Charge batteries in a well‑ventilated area on a non‑flammable surface and avoid leaving batteries unattended for extended periods. Store the charger and batteries in a cool, dry place when not in use.
