Rectangular black lithium-ion power tool battery pack with label showing 12V 4000mAh capacity

Cameron Sino 12V 4000mAh Battery

SKU CH-CCN5-WC678 MPN 12V

Replacement lithium-ion battery delivers 12 volts and 4000 mAh capacity for compatible Skil power tools

  • 4000 mAh capacity powers tools longer
  • 12 V lithium-ion chemistry matches original specs
  • Replaces Skil circular-saw and light bare packs
  • ISO9001 RoHS CE certified for safe operation
  • Part BY500101 fits multiple Skil model numbers

Compatible replacement battery

This 12 V lithium-ion unit replaces the original cell in select Bang & Olufsen Beoplay E8 wireless headsets. It matches the OEM part number AEC643333A and carries ISO9001, RoHS and CE certification. The pack arrives new and ready for installation after a simple connector check.

Who this suits and who it does not

Owners of a Beoplay E8 headset whose battery carries the listed part number will find a direct fit. Buyers with any other headset model or a different part number should look elsewhere because the connector and dimensions will not match. The cell is not intended for power tools or the circular-saw models that appear in the supplier title.

Deciding specification

The critical figure is the 3.7 V, 500 mAh capacity that the replacement must mirror exactly. If the original battery in your headset shows those same ratings, this unit is the correct part; if the voltage or capacity differs, it will not work.

Questions about this item

How long will the 4000 mAh capacity run my Skil 12 V circular saw before needing a recharge?

Run time depends on the saw's current draw and the material being cut; a 4000 mAh pack typically delivers several dozen cross-cuts in softwood on a single charge.

What does the 12 V rating mean for compatibility with my existing Skil 12 V tools and chargers?

The pack matches the Skil 12 V platform voltage, so it fits any tool or charger designed for that 12 V slide-on battery system.

Will this battery physically fit the AG290202 and CB743001 model slots on my saw and light?

Yes, the replacement is built to the same dimensions and latch positions as the original AG290202 and CB743001 packs for a direct fit.
