Our take on the Dyson DC31, DC34, DC35, and DC44 Type B Battery

This is a replacement battery pack for older Dyson cordless vacuums that use the Type B screw-release battery: DC31, DC34, DC35 and DC44 models, including the Animal and Exclusive variants. It is the fix for a vacuum that won't start, won't hold a charge or runs for only a few minutes. It suits owners keeping an older handheld running rather than buying a new machine. The catch is fit: Dyson used several battery mounts across these models, so the screw-release Type B has to match your vacuum exactly. Expect the runtime of a fresh original pack, not an upgrade.

Best forOwners of a DC31, DC34, DC35 or DC44 whose battery no longer holds chargeKeeping an older Dyson handheld out of the trashA spare pack for a second vacuum or a backup charge
Pros
  • Restores a vacuum that won't turn on or hold a charge
  • Fits the listed DC31, DC34, DC35 and DC44 variants
  • Screw-release Type B mount is simple to swap
  • Cheaper than replacing the whole vacuum
Cons
  • Only fits Type B screw-release models, not other Dyson batteries
  • No runtime gain over the original pack
  • Older models have limited parts support elsewhere
  • Off-brand cells may age faster than Dyson's own

Questions and answers

Will it fit my Dyson?
Only if your vacuum uses the Type B screw-release battery. It is listed for DC31, DC31 Animal, DC34, DC35, DC35 Animal, DC35 Exclusive and DC44. Check the battery mount before ordering.
Will it bring a dead vacuum back to life?
If the battery is the problem, yes. A vacuum that won't turn on, won't hold a charge or dies quickly is the usual sign. If the motor or trigger is faulty, a new battery won't help.
Does it last as long as the original?
Expect roughly the original runtime when new. Capacity fades with age and charge cycles, as with any cordless pack.
Is it better than a newer Dyson?
It keeps an older machine running for less than a new vacuum. Newer Dyson cordless models run longer and have more power, so weigh the repair against an upgrade.
What's in the box?
The battery pack. The screw-release mount is part of the battery, so no separate adapter is needed for compatible models.
Where is the Dyson DC31, DC34, DC35, and DC44 Type B Battery cheapest?
At iFixit, for $49.99, as of our latest check.
