Replacement Battery for AeroFlex 3500A

This lithium-ion pack replaces the original battery in AeroFlex 3500A and Cobham AvComm 8800S test equipment. It delivers 10200mAh at 11.1V and matches the factory part number AeroFlex 7020-0012-500. The unit is built to ISO9001, RoHS and CE specifications and includes a fully decoded chip that communicates with the host device exactly as the original did.

Installation and Common Issues

The pack fits into the instrument's battery compartment using the existing connector; many users report the swap takes only a few minutes after watching online guides. The main risk is seating the connector incompletely, which can prevent the device from recognising the new cell. Using a low-quality charger may also reduce cycle life, so the original or an equivalent power supply is recommended.

Sustained Load Behaviour

Under continuous operation the battery maintains a stable 11.1V output until the protection circuit triggers at the end of discharge. Overcharge, over-discharge, over-voltage and short-circuit safeguards prevent damage during long test sessions. The 113.22Wh capacity supports extended field use, and the pack reaches full rated performance after two or three complete charge-discharge cycles.
