Replacement battery for Cardo headsets

This 3.7 V 800 mAh lithium-polymer cell replaces the original BAT00002 pack used in Cardo G4, G9 and G9x communicators as well as the SCHUBERTH C3 system. It matches the 2.96 Wh energy rating and fits the 49.20 x 19.50 x 9.20 mm cavity without modification. The black housing keeps the original look.

Direct swap for WW452050-2P and ZN452050PC-1S2P

The cell is a one-to-one substitute for part numbers WW452050-2P and ZN452050PC-1S2P, restoring talk time when the factory battery no longer holds a charge. Installation requires only opening the headset compartment and reconnecting the existing lead. The jump is worth it when runtime has dropped below a usable level.

Riders needing a fresh OEM-spec cell

Motorcyclists who want a new 100 % OEM-compatible battery for the listed Cardo and SCHUBERTH units will find this a direct fit. Buyers with other headset brands or different form-factor requirements should look elsewhere.

Questions about this item

Will the 49.20 x 19.50 x 9.20 mm dimensions fit my Scala Rider G9 battery compartment?

Yes, those are the exact dimensions of the DS-CS-SRD400SL; it matches the original Cardo BAT00002 form factor for G4, G9, G9x and SCHUBERTH C3 headsets.

What is the correct way to connect the 2-pin plug during installation?

Align the red and black leads with the corresponding terminals on the headset PCB; reversing polarity will prevent the unit from powering on.

When should I replace this 3.7V 800mAh Li-Polymer cell?

Replace it when the headset no longer reaches full charge or runtime drops noticeably below the original 2.96 Wh capacity.
