Quick answer

Match the battery to how your Dyson handheld holds its pack, not to the model name alone. If your DC44, DC45, DC34, DC31 or DC35 battery slides in and latches with no separate fasteners, choose the CELLONIC click-in 2500mAh battery (product 2062090). If a cover or bracket is fixed with screws, choose the CELLONIC screw-fit 2500mAh battery (product 2062169). Both are 2500mAh replacements, so the deciding factor is the mount, not the capacity.

Why the same Dyson handheld can take two different batteries

Dyson built the DC30, DC31, DC34, DC35, DC44 and DC45 across several production runs, and the battery housing changed between them. Some versions clip the pack straight into the handle; others trap it behind a screwed-down cover or bracket. That is why two 2500mAh CELLONIC batteries exist for the same list of vacuum models: they are mechanically different, not electrically different.

The practical consequence is simple. A click-in pack will not bolt into a screw-fit housing, and a screw-fit pack will not latch into a click-in slot. Before ordering a Dyson DC44 battery replacement, look at the underside of your handheld and note whether you can release the pack by hand or whether you need a screwdriver.

How to identify your mount in under a minute

Remove the wand and bin first so you can turn the handheld over safely. On a click-in design you will see a release catch or button that frees the battery directly. On a screw-fit design you will see a cover, plate or bracket held by screws, with the battery sitting underneath it.

If the housing is ambiguous, photograph the battery bay and compare it with the product images before you buy. Neither CELLONIC listing supplies a full compatibility list by serial number, so the physical mount is the only reliable check.

  • Click-in: battery releases by hand, no tools needed.
  • Screw-fit: battery sits behind a screwed cover or bracket.
  • When in doubt, check the bay, not the model number on the rating label.

What 2500mAh actually changes for you

Both batteries are rated at 2500mAh, so run time between charges should be comparable whichever mount you choose. That figure matters most if your original pack has faded: a tired cell often shows up as a vacuum that cuts out after a few minutes on max power, not as a vacuum that fails to start.

Capacity is not a reason to pick one version over the other here. Treat 2500mAh as the baseline both options share, and make your decision on fit, price and whether you want screws included.

Practical notes before you order

Dyson part number 967813-03 appears on the click-in listing, which is useful if you are replacing a pack whose label you can still read. The screw-fit listing instead names more specific variants, including the DC34 Animal, DC44 Animal and DC35 Multi Floor, so owners of those versions should start there.

Neither product record states a cell chemistry, cycle rating or warranty term beyond the general listing claims, so do not assume those details. If a long guarantee is your priority, check the product page before checkout rather than relying on the model list.

Decision rules for buying a Dyson handheld battery

  • Battery releases by hand: Choose the click-in 2500mAh pack (product 2062090) and confirm your old label shows 967813-03 if it is still legible. No tools required for the swap.
  • Battery hides behind a screwed cover: Choose the screw-fit 2500mAh pack (product 2062169), which ships with screws for the cover or bracket. Keep the old screws as spares in case one strips.
  • You own a named variant: DC34 Animal, DC44 Animal, DC31 Animal or DC35 Multi Floor owners should start with the screw-fit listing, which names those versions explicitly. Variant names are a stronger signal than the base model number.
  • Run time is your main complaint: Both packs are 2500mAh, so neither offers extra capacity over the other; a sudden cut-out on max power usually points to a worn cell rather than a wrong mount. Replace the pack, then re-test run time before assuming a motor fault.
  • You cannot confirm the mount: Do not order on model name alone. Compare your battery bay with the product images first, because neither listing gives a serial-number compatibility table. A five-minute check avoids a return.

The two CELLONIC options side by side

Is this the right battery for your Dyson?

Best for

  • Owners of a DC30, DC31, DC34, DC35, DC44 or DC45 whose pack releases by hand or sits behind a screwed cover
  • Anyone replacing a faded original pack who wants a 2500mAh replacement without changing tools or chargers
  • DC34 Animal, DC44 Animal, DC31 Animal and DC35 Multi Floor owners who need the screw-fit version

Not for

  • Dyson models outside the DC30 to DC45 handheld range, which are not named in either listing
  • Anyone who needs a confirmed warranty term, cell chemistry or cycle rating before buying
  • Velux or Albrecht device owners, who need their own model-specific packs instead
