Replacement Power for Universal Remotes

This three-pack of Kastar MX990 lithium-ion cells replaces the original batteries in a range of universal remote controls. Each unit delivers 1900mAh at 3.7V for extended operating time between charges. The pack suits households that rely on multiple remotes and want a single spare set.

Built-In Protection and Direct Fit

The cells meet UL1642 and CE safety standards and include circuits that guard against over-charge, over-discharge, over-voltage, over-current and over-heating. They match the form factor of the Acoustic Research ARRX18G, Nevo HK-NP60-850 and One For All SN03043TF part numbers, so they slot into the Nevo C3, UEI-NEVO C3, One For All ARRX18G, URC 11-8603, URC 8603 and Xsight Touch without adapters.

Steady Output with No Active Cooling

Lithium-ion chemistry provides consistent voltage through the discharge cycle and the protection circuit prevents thermal events during normal use. There are no fans or moving parts, so operation is silent and power draw is limited to the remote's own consumption. The 7.03 Wh rating supports long sessions before a recharge is needed.

Questions about this item

Does the 3.7 V lithium-ion chemistry limit the usable capacity to the rated 1900 mAh?

Yes, the 3.7 V Li-ion cells deliver the stated 1900 mAh (7.03 Wh) and include built-in protection against over-charge, over-discharge, over-voltage, over-current and over-heating.

What physical size must the battery compartment accommodate for each MX990 cell?

Each cell measures 3 by 2 by 3 inches, so the compartment needs at least that much space per battery.

How are the MX990 batteries installed in a Nevo C3 remote, and what step is often missed?

Open the battery cover, insert the three cells matching the polarity markings, then close the cover securely; the step often missed is verifying the correct orientation for each cell before snapping the cover shut.
