If your Dyson V11 cordless vacuum cleaner is no longer delivering the suction power and runtime it once had, it’s probably time to replace its battery.

With a premium Dyson V11 replacement battery from CELLONIC, you can restore your vacuum’s full performance without the cost of buying a whole new Dyson or an expensive OEM battery – a reliable, sustainable and cost-saving alternative for effective cleaning.

100% compatibility – which Dyson models use the V11 battery?

Click-in batteries: for newer models such as V11 Outsize, V11 Torque Drive, V11 Absolute Extra, V11 Fluffy Extra and V11 Total Clean Extra, batteries can be easily swapped at the push of a button.

Screw-in batteries: for earlier models such as the Dyson V11 SV14, replacement is still simple but requires a screwdriver.

Important: Always check the battery type (Click-in or Screw-in) and the part number (e.g. 970938-01, 970425-01, SV14, SV15, SV18) on your current battery before ordering to ensure full compatibility.

Replacing the battery in your Dyson V11 is quick and straightforward. First, identify whether you have a Click-in or Screw-in battery:

For Click-in batteries

1. Switch off your Dyson V11 and disconnect it from the charger
2. Press the release button to remove the old battery pack
3. Slide the new Click-in battery into place until it locks securely
4. Fully charge before first use

For Screw-in batteries

1. Switch off your Dyson V11 and disconnect it from the charger
2. Use a screwdriver to remove the screws holding the battery in place (usually one on the handle and one underneath the unit)
3. Carefully remove the old battery
4. Insert the new CELLONIC battery
5. Refit the screws
6. Fully charge before first use

Most Dyson V11 replacement batteries are compatible with the original Dyson charger, so you can continue using your existing dock or cable.

• First charge: fully charge the battery before first use
• Avoid deep discharges: recharge when capacity drops to around 20%
• Boost mode: only use when needed, as it drains the battery faster
• Storage: store in a cool, dry place at around 40% charge if unused for long periods
• Safety: never expose batteries to heat, open them or damage them. Always recycle at a battery collection point – never in your household waste
