Replacement Battery for Avionics Test Sets

This lithium-ion pack replaces the original power source in Cobham AvComm 8800S, IFR 3550R, IFR 4000, IFR 6000 and IFR 8800S analysers. It delivers 7800mAh at 11.1V and matches the OEM dimensions of 164.80 x 70.90 x 18.60mm. The integrated decoded chip communicates with the host instrument exactly like the factory cell.

Steady Output During Extended Test Sessions

The 86.58Wh capacity supports prolonged RF measurements, signal monitoring and calibration routines without the voltage sag seen in aged cells. Protection circuits guard against over-charge, over-discharge, over-voltage and short-circuit events during continuous operation. A fresh pack reaches full rated runtime after two or three complete charge cycles.

Rugged Construction for Field and Bench Use

The 422.2g housing fits the battery bay without modification and the connector aligns with the original keying. Shock-absorbing foam in the retail package protects the cell during transport to remote sites. Do not disassemble, expose to fire or water, or store above 60°C.

Questions about this item

Does the 11.1V 7800mAh lithium-ion pack run hot during extended test sessions?

The battery is rated at 11.1V and 7800mAh with over-charge, over-discharge, over-voltage and short-circuit protection built in to limit heat rise during long use.

Which analyser models accept the 7020-0012-500 pack without an adapter?

It fits the 3500A, Cobham AvComm 8800S, IFR 3550R, IFR 4000, IFR 6000 and IFR 8800S analysers directly.

Will the 164.80 x 70.90 x 18.60 mm pack sit in the same bay as the original battery in an IFR 4000?

Yes, the dimensions match the original specification so the pack occupies the identical bay in the IFR 4000.
