Cameron Sino CS-800LI replacement battery

The Cameron Sino CS-800LI is a 950mAh 3.52Wh lithium polymer battery built for Eartec ComStar Wireless Headsets. It supplies 3.7V and measures 43.00 x 35.80 x 13.00mm. The pack weighs 27.0g and includes a fully decoded chip that works like the original. Overcharge, over discharge, over voltage and short circuit protection are integrated.

Replaces the original Eartec headset pack

This cell replaces the factory battery when runtime drops or the headset will not hold a charge. The jump is worth it when the original pack no longer lasts a full shift or shows swelling. It restores the original 950mAh capacity without modification. Buyers who need a higher capacity than 950mAh cannot use this model.

Simple two-wire connector swap

Installation requires opening the headset housing and plugging the new connector into the existing socket. Most users complete the swap in minutes with basic tools. The most common issue is reversing the connector polarity, which prevents the headset from powering on. A second issue is failing to seat the pack flat, which can stress the wires. The battery reaches peak performance after two or three full charge cycles.
