Replacement Battery for Astro A50

This Centenex Electronics DS-CS-AGM500SL battery restores power to the Astro A50 wireless headset. It matches the original SRP603443 part number and delivers 3.7 V at 800 mAh capacity. The lithium-polymer cell is built to OEM specifications for direct compatibility.

Compact Li-Polymer Build and Direct Fit

The black pack measures 44.80 by 33.40 by 5.00 mm and slides into the headset without modification. A pre-wired connector aligns with the existing socket, so no soldering or adapter is required. The slim profile preserves the original weight balance and ear-cup clearance.

Swaps Out a Depleted Original Cell

This unit replaces a worn-out Astro SRP603443 battery that no longer holds a usable charge. The upgrade is worth it when the headset cuts out early or fails to power on after a full cycle. It is not for users who need a higher-capacity pack or a different voltage.

Questions about this item

What voltage and capacity does the 3.7V 800mAh Li-Polymer cell deliver in practice?

It supplies 3.7 volts and 800 milliampere-hours, giving 2.96 watt-hours of energy for the Astro A50 headset.

Will the 44.80 x 33.40 x 5.00 mm pack fit the original battery compartment?

Yes, those exact dimensions match the SRP603443 form factor so the cell seats correctly in the A50 housing.

Which connector orientation is required when fitting the replacement cell?

Align the plug with the header on the headset PCB before pressing it in; reversing the connector prevents the headset from powering on.
