Replacement battery for Dyson handhelds

The Cameron Sino DC31 is a new replacement battery built for select Dyson cordless vacuums. It fits models DC31 Animal, DC34, DC34 Animal, DC35, DC35 Multi Floor, DC56 and DC57. The pack restores runtime on units whose original cells have faded. Buyers needing power for other vacuum brands or for upright Dyson models cannot use this part.

Direct-fit design with robust cells

The battery matches the original form factor so it slides into the handle without adapters or tools. Its casing aligns with the vacuum’s latch and charging contacts, keeping the device balanced during cleaning. Quality cells deliver steady current to maintain suction through a full charge cycle. No soldering or firmware steps are required for installation.

2500 mAh capacity at 57.00 Wh

This energy rating determines how long the vacuum runs between charges on the supported models. A lower figure would cut cleaning time short; a higher one is not offered for this form factor. Match the mAh and Wh to the label on your old pack before ordering.

Questions about this item

What voltage does the 2500mAh 57.00Wh DC31 battery deliver?

This replacement battery supplies the same voltage as the original Dyson pack for the DC31 Animal, DC34, DC34 Animal, DC35, DC35 Multi Floor, DC56 and DC57 models, so the vacuum runs at its designed power level.

Will the DC31 battery pack fit inside my DC35 Multi Floor handheld vacuum?

Yes, the Cameron Sino DC31 battery is shaped to match the original pack dimensions for the DC31 Animal, DC34, DC34 Animal, DC35, DC35 Multi Floor, DC56 and DC57, so it slides into the battery compartment without modification.

How do I install the DC31 replacement battery and what step is often missed?

Remove the old pack, insert the new DC31 battery until it clicks, then charge it fully before first use; the step people skip is that initial full charge, which calibrates the 2500mAh 57.00Wh cells for maximum runtime.
