Replacement battery for AeroFlex IFR 8800S

This lithium-ion pack replaces the original battery in AeroFlex IFR 3550R, 3500A, IFR 8800S, IFR 6000, IFR 4000 and Cobham AvComm 8800S test equipment. It matches the 7020-0012-500 part number and delivers 11.1 volts with a rated capacity of 7800mAh. The cell chemistry is lithium and the pack is sold as a single unit.

Built-in protection and certifications

Over-charge, over-discharge, over-voltage and short-circuit protection circuits are integrated to extend service life and prevent damage during fault conditions. The pack carries ISO 9001, RoHS, CE, UN 38.3 and MSDS certifications, confirming compliance with quality, substance-restriction and transport-safety standards. Dimensions are 166.0 by 70.0 by 18.6 millimetres and weight is 555.0 grams.

Capacity and voltage limits

The nominal energy content is 86.58 watt-hours, which defines the maximum energy available per charge cycle at 11.1 volts. Runtime depends entirely on the current draw of the specific IFR instrument in use; no universal operating time can be stated. The pack is not intended for devices requiring a different voltage, connector pinout or physical envelope.

Questions about this item

When will the 7800mAh lithium pack need replacing?

Lithium cells typically last several hundred charge cycles before capacity drops noticeably; the 86.58Wh rating means each full cycle delivers that energy until aging reduces usable runtime.

What limits continuous operation of the 11.1V battery?

The 7800mAh capacity sets the energy ceiling; once the stored 86.58Wh is depleted the pack must be recharged before the IFR 8800S can run again.

How hot or noisy does the 555g battery get during all-day use?

The pack has no moving parts and generates only modest warmth during discharge; it runs silently and stays within normal operating temperature for lithium chemistry.
