Replacement Battery for Cardo Headsets

This Centenex Electronics lithium-polymer cell is built to replace the original power pack in Cardo Q1 and Q3 Scala Rider headsets. It delivers the same 3.7 V nominal voltage and 320 mAh capacity as the factory unit. The pack measures 51.50 x 20.40 x 4.60 mm and finishes in black.

3.7 V 320 mAh Li-Polymer Specification

The single figure that decides fit is the 1.18 Wh energy rating matched to the WW452050PL_C part number. Only devices listed for that exact part number will accept this cell. No other voltage or capacity combination is supported by the host headset.

Riders Needing a Direct Swap

Suits owners of a Cardo Q1 or Q3 Scala Rider whose original battery has faded. Buyers whose headset uses a different part number or who require a higher capacity cell should look at something else.

Questions about this item

How long will the 320 mAh capacity run my Cardo headset?

The 320 mAh cell stores 1.18 Wh at 3.7 V, giving typical talk time in line with the original Cardo Q1 and Q3 specifications.

Does the Li‑polymer chemistry need a special charger or connector?

It uses the standard two‑wire JST‑style connector fitted to Cardo WW452050PL_C packs, so the headset’s own charging circuit handles it.

Will the 51.50 × 20.40 × 4.60 mm pack fit inside my Q1 or Q3 housing?

Those dimensions match the factory battery cavity exactly, allowing the pack to sit flush under the original cover.
