FLAGPOWER Rechargeable Li-ion Replacement Battery 22.2V 2000mAh for Dyson DC31 DC34 DC35 DC44(Not Fit Type B,DC44 MK2)917083-01 91708301 Handheld Vacuum Cleaner

I purchased this as a replacement for my original Dyson battery on my V8 Absolute, which I have owned since Dec 2016. Over the past month my original battery had really gone down hill and would only run a couple of minutes on MAX with a floor attachment.First Impressions:This FLAGPOWER replacement battery came simply packaged with a plastic cover over the contacts area, wrapped in a single bubble wrap bag, in a simple box. In my book this is a positive.... no extra, bulky, useless packaging to deal with. Note in the pictures that I had previously removed the battery from the box and then repackaged for purpose of taking pictures. When it arrived the QC sticker was intact and sealed.I've provided several side-by-side pics of this replacement batter beside the original Dyson battery. In all cases, the FLAGPOWER is on the left and Dyson original on the right. The FLAGPOWER battery looks to be well made and, aside from a few cosmetic differences in the plastic molding, it is identical in size and shape to the Dyson. In one of the side shot pics there's apparently some sort of optical illusion going on (to me anyway) as the angle of the "probe" part that inserts into the Dyson looks different between the two. But I assure you this wasn't the case and the replacement battery aligned perfectly in the handle of the Dyson.Installation of the battery on the Dyson handheld was easy- remove 3 small screws, pull old battery out, put new battery in, replace 3 screws. I had no issues using this battery with my original Dyson cradle. The first time I place it in the cradle I could tell there was more resistance to the power plug going into the port in the battery but after a few uses it seems to have loosened up a bit. Even the first time didn't feel like an excessive amount of force though so no concerns here.I don't see this as a negative in any way, but I did note that the 3 blue LED light indicators seem to be reversed in order from the way they are on the original Dyson.As for performance- the Dyson V8 runs normally and works great with this battery. I have not done a controlled test to see how long this battery will last, but as I didn't have any controlled test data from my original Dyson to compare it to, really wouldn't be of great value. But I can say that this battery has allowed me to get back to my routine of doing the entire downstairs floor each night. This routine includes using the floor brush attachment on one area rug in the den and then using the hard floor head to quickly go over the flooring in kitchen, breakfast area, dining room, and foyer. I was always able to complete this task with at least a little of the Dyson battery remaining (until it started dying) and the FLAGPOWER battery has been able to do the same cleaning routine.I plan to update this review after a few months of use, or sooner if I notice any issues with the battery. But for the time being I'm very pleased with the purchase. Not too pleased that I spent $600 on a vacuum and had to buy a new battery for it after a year.... but not surprised either. Batteries are always the weak link in cordless tools.UPDATE 1 (1/21/2018)We've been using our Dyson V8 daily for about two weeks now with the replacement battery. So far no issues at all. It appears to be able to run for at least the same amount of time as it did with original Dyson battery.

Excellent! Excellent! product! I cannot be happier. We happened to call Dyson and they stated the battery for our particular vacuum was no longer being offered. They told us we could receive a 20% discount if we purchased a new vacuum which, was more uptodate for $300 plus with a discount... crazy! Absolutely not! Our vacuum is only 5 years old and it never worked properly. Anyway, I'm so thankful this battery was offered on Amazon and it works like a charm. For $20 plus, my vacuum is working as if I just purchased it. Thank you, thank you!

This worked initially, for two weeks, but now won't keep a charge for one use. It is pretty sad too, considering the cost. To use this, you must keep it plugged in continuously, then when fully charged you get 7 minutes worth of run time. I wish Amazon would hold manufacturers responsible for inferior products. That would be great, but at the volume that they sell, it won't happen. I am let down with this product.

Bought this to replace a dying Dyson battery pack for our hand held vacuum cleaner. So far it has outperformed the factory battery, but only time will tell as we use this vacuum at least once a day. It took maybe 5 minutes to remove the old battery and install this new one.

What a mistake. It sent my expensive Dyson smoking and flaming. And it's definitely the right battery according to the description. Steer clear!

Perfect fit. I had an issue with my Hand Dyson. I was not sure if it was the battery or the unit motor. I ordered this replacement battery via Prime and it fit and worked perfectly. The new battery actually gave the hand held vacuum a boost in power. I was so pleased I ordered a 2nd unit.

Highly recommended, good customer service and works as advertised.Is a great addition to my Dyson cordless vacuum cleaner. Keep the additional battery charged. I can swap out the used battery for a freshly charged one. And charge that one while I continue to work. The original battery does not hold a good charge so I will be purchasing another battery in the future.An extra battery has expanded the usefulness of the cordless Dyson. Love it!

Was scared it wouldn't fit given how specialty each Dyson is. We have two and I know the other one didn't fit. Needless to say this fits perfectly and I think has a longer life, maybe higher miliamprage than stock.

When my Dyson handheld battery packed up I knew I’d have to get a new battery or a new Hoover. Dyson wanted £60.00 for a battery with only a 1 year guarantee on it. This battery at £25.99 was a bargain in compassion. It arrived and already had “charge” in it and my hoover worked straightaway. I obviously plugged it in and let it fully charge/ So far so good, and this does seem to be a good buy. I will update if need be if I do happen to have any issues.

experts say an original dyson battery should last 2-3 years, so this battery is doing what it is designed to do up until now but cannot comment on longevity as its too early[watch this space]but I have no doubt it will match the original.

Good quality, reasonable price

worked fine to start but very soon lost its ability to recharge and then stopped working all together. After 8 months failed completely.

My Dyson kept cutting out and would not work on Max. Since replacing with this battery like having a new hoover. Thank you

Works well and good price

I was very pleased with the battery for my Anima ld31 , easy to install and working well after to be charged. I don't need to buy a very expansive other DYSON. Thank you very much

Prompt delivery, and easy to fit.

Fits into my DC35 perfectly right away.

Very good value for money

Dyson - ease of fitting and works like new

Product was exactly right to replace battery pack in my Dyson DC 44 at a very reasonable price plus very speedy delivery

Very good buy, run time is as good as original, easy to install, don’t know if it will last as long as an original but at this price you can buy three for the price of one original.

this item doesn't hold the charge and I am still waiting for a replacement.

Help i have ordered the wrong mode no. I have been given returns details but can not find a courier who ll return it.
