Compatible Battery Pack

This Kastar four-pack replaces the original power cells in Nevo C3, UEI-NEVO C3, One For All ARRX18G, URC 11-8603, URC 8603 and Xsight Touch remotes. Each lithium-ion unit delivers 3.7 V and 1900 mAh for extended control sessions. The bundle suits households that manage several universal remotes from a single charger.

Simple Drop-In Swap

Installation is a straightforward battery-door exchange; no tools or firmware steps are required. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating during the swap. The only common issue is inserting a cell with reversed polarity, which the keyed compartment prevents.

Capacity and Runtime Limits

Four cells rated at 7.03 Wh each provide ample headroom for daily universal-remote use across multiple rooms. Heavy macro programming or continuous backlight demand will drain a cell faster than casual channel changes. The pack is not intended for high-draw devices such as digital cameras or video lights.

Questions about this item

How do I verify the Kastar MX990 batteries are working correctly after installing them in my Nevo C3 remote?

The Nevo C3 should power on immediately and show normal battery-level indication; each cell delivers 3.7 V and 1900 mAh with built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection.

What comes in the 4-pack and do I need a separate charger for these Li-Ion cells?

The box contains four Kastar MX990 lithium-ion batteries (model BA-4B-MX990-I); a compatible charger for 3.7 V Li-Ion cells is not included and must be purchased separately.

Which capacity should I choose between the listed 1900 mAh and 7.03 Wh ratings for my One For All ARRX18G?

Both figures describe the same cell — 1900 mAh at 3.7 V equals 7.03 Wh — so the single 4-pack version covers both specifications.
