Compatible ventilator battery

The KingSener 1113779 is a 14.8V 4.4Ah lithium-ion replacement battery rated at 66Wh. It matches part numbers 1043572, 1055806 and 1113779 for Trilogy 202 and Trilogy 100 ventilators. Users who need a direct swap for the original pack will find the voltage and capacity identical. Buyers requiring a different voltage or a higher capacity pack should look elsewhere.

Thermal and power profile

The pack uses standard Li-ion cells assembled in China with a black outer casing. No active cooling or fan is included, so heat dissipation relies on the ventilator’s own enclosure during normal operation. Internal resistance is typical for this chemistry and capacity, keeping voltage sag modest under the load profiles specified by the manufacturer. The battery does not add audible noise to the system.

Build and daily handling

The housing is a rigid black shell shaped to the original footprint, allowing tool-free insertion into the ventilator’s battery compartment. Connectors align with the OEM interface so the latch engages securely on each swap. No extra cables, mounting brackets or charging hardware are supplied; the unit is intended to be charged inside the host device. Users who need an external charger or a different connector layout will not be served by this model.

Questions about this item

How do I install the KingSener 1113779 battery in my Trilogy 202 ventilator and what step is often missed?

Align the battery contacts with the compartment rails, slide it in until the latch clicks, then verify the device powers on without the AC adapter connected.

What maintenance or replacement will the KingSener 1113779 battery need over time?

As a Li-ion pack rated at 4.4Ah and 66Wh, it will gradually lose capacity; plan to replace it once runtime no longer supports your prescribed therapy duration.

What limit appears first during continuous use of the KingSener 1113779 battery on a Trilogy 100?

The 66Wh capacity sets the runtime ceiling; under sustained load the pack will deplete before any thermal or voltage cutoff is reached.
