Four-pack Li-ion replacement

This set provides four Kastar lithium-ion cells rated at 3.7 V and 1900 mAh each, delivering 7.03 Wh per battery. They are built as direct replacements for a wide range of Universal Remote Control handsets. The pack suits installers or owners who maintain multiple remotes and want a single purchase to cover all units. Buyers needing cells for non-URC devices should verify compatibility before ordering.

Built-in protection circuits

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards that meet UL1642 and CE requirements. These circuits prevent damage from faulty chargers or extended storage and help extend the usable cycle life of every battery. No external management board or firmware update is required; the protection is integrated into the pack itself.

7.03 Wh per cell capacity

At 7.03 Wh each, the batteries comfortably power URC MX 950, MX 980, MX 990, MX 1200, X-8, TRC-1080, TRC-820 and earlier 810, 880, 890 models through typical daily use. Runtime will fall short for remotes with continuous backlighting or RF transmitters that draw higher peak currents. The four-pack gives enough spares to rotate cells and avoid downtime during heavy sessions.

Questions about this item

How often will the 1900mAh Li-Ion cells need replacing?

Lithium-ion cells typically last several hundred charge cycles; with built-in over-charge and over-discharge protection the usable lifespan is extended.

What limits runtime during continuous remote operation?

The 7.03 Wh capacity sets the energy budget; sustained backlight or RF use will drain the 1900mAh reserve faster.

Do the batteries get hot or draw extra power when the remote is used all day?

Integrated over-heating and over-current protection circuits keep temperature and power draw within safe limits during extended use.
