3-Pack Li-Ion Replacement for URC Remotes

This three-pack supplies 1900mAh lithium-ion cells rated at 3.7V and 7.03Wh each. They are built as direct replacements for URC MX-990, MX-980, MX-950, MX-890, MX-880 and MX-810 handsets. Installers and homeowners who maintain multiple remotes can swap fresh packs without waiting for a single unit to recharge. Buyers needing higher-capacity cells or different form factors should look elsewhere.

Thermal Behaviour and Power Draw

Lithium-ion chemistry runs cool during typical remote-control duty cycles. The integrated protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. Cells meet UL1642 and CE safety standards. No active cooling or special ventilation is required in normal use. The pack is not suited for high-drain devices that demand sustained heavy current.

Bundled Value and Protection

Three matched batteries arrive ready to deploy across a household or job site. The over-charge, over-discharge, over-voltage, over-current and over-heating safeguards extend cycle life and reduce replacement frequency. Compatibility covers URC models including 11N09T, NC0910, RLI-007-1, LIT0404, MX-1200, X-8, TRC-1080 and TRC-820. No charger or firmware is included in the package.

Questions about this item

How do I install the Kastar MX990 battery in my URC MX-990 remote, and what step is often missed?

Open the battery compartment, insert the 3.7V Li-Ion cell matching the polarity markings, and close the cover. The step often missed is ensuring the protection circuit board sits flush so the cover latches fully.

What maintenance or replacement will the Kastar 1900mAh pack need over time?

Lithium-ion cells degrade with charge cycles. Expect reduced run-time after several hundred cycles; replace the pack when the remote no longer holds a full day's charge.

What limit appears first during sustained use of the Kastar 7.03 Wh battery?

The built-in over-heating protection circuit will interrupt output if the cell temperature rises too high during continuous heavy transmission, pausing the remote until it cools.
