EGR DC31 22.2V replacement battery for Dyson DC45 DC34 DC35 DC44 (Type A, not Type B) – 917083-01

What it is and why you’d want it

This EGR replacement battery is designed for Dyson handheld vacuum models in the Type A DC31 family, including DC31, DC34, DC35, DC44 and DC45 models listed under 917083-01. If your current battery no longer holds charge for long enough, swapping it for a compatible replacement can be the simplest way to get your handheld back to proper day-to-day use.

On paper, this is aimed at people who want more runtime and a safer, more modern lithium-ion charging experience, rather than hunting for an upgrade they don’t actually need. It’s a battery-focused purchase: the goal is to restore cleaning time, not change how the vacuum works.

Compatibility you should double-check first

The biggest “gotcha” here is compatibility. The listing is clear that it is for Type A, and not for Type B. It also names a set of compatible series and part references, including 917083-01 and other codes such as 17083-2811, 18172-01-04, 17083-4211, 18172-0201, and 917083-03.

If you’re unsure whether your Dyson unit is Type A or Type B, it’s worth verifying before you buy. Buying the wrong type is usually a dead end: the vacuum won’t be the one you expect, even if the part numbers look similar.

Battery life: what to realistically expect

This is the area where the listing makes its strongest case. It’s described as an upgraded lithium-ion replacement with high-energy-density cells. The claimed performance targets are: - around 28 minutes in normal cleaning mode - up to 15 minutes in high-performance mode for stronger suction

That’s useful context when you’re deciding whether it’s “enough” for your routine. For example, if you mostly do quick kitchen crumbs, stairs, or car-seat detailing, normal mode timing can be the one you care about most. If you regularly do deep cleaning on upholstery using high suction, you may feel more limited by the shorter high-performance window.

Also, remember that real runtime can depend on how you use the vacuum (and which mode you stick to), so treat the figures as indicative rather than a guarantee.

What stands out in day-to-day use

A few practical details are included that matter more than marketing language.

First, it uses an intelligent control chip with protection against overcharge, overvoltage, overheat, and short circuit. That doesn’t make batteries invulnerable, but it does speak to the aim of safer charging and operation.

Second, the listing states the battery has no memory effect and can be charged at any time. In normal household use, that usually means you’re not overly restricted by charging habits—handy if you tend to top up rather than fully drain.

Third, the battery packaging includes an anti-slip strip design. This is described as helpful when the vacuum is positioned against a wall, improving grip and helping prevent the unit from falling. It’s a small thing, but it directly relates to how handhelds often live in real homes—resting awkwardly between uses.

What you get in the box (and where the value comes from)

According to the listing, you receive: - 1× DC31 battery - 2× filters

That bundled filter quantity can make this feel more complete than a “battery only” replacement, especially if your filters are also due for attention. Still, it’s not a full vacuum overhaul: if the filters, seals, or suction path need more than basic maintenance, a battery swap alone might not feel like a complete fix.

Pros and limitations to consider

Where it makes sense: - You’re specifically replacing a Type A DC31-family battery and want the stated improvement in runtime. - You want charging flexibility (no memory effect) rather than strict charge cycles. - You value the included safety protections and the anti-slip strip for wall-position storage.

Where you might want to skip it: - If your Dyson is Type B, this isn’t compatible (so it’s a straightforward avoid). - If you’re expecting a dramatic change beyond battery performance—like a new suction system, motor upgrade, or airflow redesign—this won’t be that kind of purchase. It’s primarily about battery restoration.

Care, charging, and the quick checks before you buy

Because this is a replacement battery, small checks help you avoid wasted effort: - Confirm your vacuum is Type A and matches the listed DC models/part references. - Check that the part code on your existing battery aligns with what’s stated (for example, 917083-01 where relevant). - Expect performance to vary with mode choice, high-performance mode is typically where runtime runs shorter.

Mini FAQ

Is this battery compatible with Type B Dyson handheld vacuums?

It’s described as compatible with Type A DC31 series handhelds, including DC31, DC34, DC35, DC44 and DC45 models listed in the compatibility notes.

How long does the battery last?

The listing claims about 28 minutes in normal mode and 15 minutes in high-performance mode.

What else is included besides the battery?

You receive 1× DC31 battery and 2× filters.

When it makes sense

This EGR DC31 22.2V replacement battery is a sensible buy if you’ve got a Dyson handheld in the Type A DC31 family and you want to restore real cleaning time—especially if your current battery has faded and you’re mainly relying on normal mode for everyday jobs.

It’s not the right choice if your vacuum is Type B, or if your problem is more about blockages, worn parts in the airflow path, or filter issues than battery performance. For anyone whose main pain point is “it doesn’t last long enough”, this is exactly the sort of targeted replacement that tends to pay off.

And finally, if you’re buying for the long run, it’s worth using the included protections and charging approach sensibly—charge when needed rather than waiting for a full drain, and keep an eye on the filters since they’re included in the pack.
