Replacement Battery for DUAL-LITE Emergency Lighting

This Cameron Sino lithium-ion pack replaces the original 784H74 cell in DUAL-LITE SEWLDG, SEWLDR and SEWLSG series units. It delivers 4.8 volts and 800 milliampere-hours in a 100.00 by 28.60 by 14.40 millimetre form factor weighing 82.0 grams. The pack includes a decoded chip that communicates with the host unit exactly like the factory battery.

Upgrade from Degraded Original Cells

The jump is worth it when the existing pack no longer holds a full 3.84 watt-hour charge or shows voltage sag under load. A fresh cell restores the rated runtime and ensures the emergency luminaire meets its mandated duration without rewiring or firmware changes.

Limits of the 4.8 Volt Lithium-Ion Platform

The chemistry is rated for storage up to 60 degrees Celsius and must not be exposed to fire, water or physical disassembly. Performance stabilises after two or three full charge-discharge cycles, and a low-quality charger will shorten service life. No provision exists for series or parallel strings beyond the single-pack design.

Questions about this item

Will the 100.00 x 28.60 x 14.40 mm dimensions fit my DUAL-LITE emergency light?

Yes, the pack matches the original 784H74 footprint exactly, so it slots into the SEWLDG and SEWLS series housings without modification.

What is the installation step people often miss when fitting this 4.8 V pack?

The decoded chip must click fully into the device connector; a loose plug prevents the light from recognising the new cell.

How many charge cycles before the 800 mAh capacity stabilises?

The manufacturer advises two or three full charge-and-discharge cycles for the lithium-ion cells to reach rated runtime.
