EGR Upgraded DC35 Battery Replacement Compatible with Dyson DC31 DC34 DC35 DC44 DC45 917083-01 Handheld Vacuum Cleaner (Not Fit All Type B)

I have a Dyson V8 and the battery has been starting to run down a lot sooner. I got this which has a higher capacity. It came with the battery along with replacement screws, a screw driver and replacement filters for the intake and exhaust. The install was very simple, remove the three screws and the battery comes out very easily. Put the new one in it's place and replace the screws. While it came with replacement screws, I just used the original ones. They were a little longer. There is one screw on the handle and two under the hatch at the bottom (see pics) The replacement battery looks very similar with a few minor differences that you can't see once it's installed. The new battery does have a little rubber bumper patch that sits flush at the bottom which is a nice touch. Although the battery has a higher capacity, it's not any larger. The battery feels well made very similar to the original one. The replacement filters seem just fine, similar to other aftermarket ones I've used in the past. I charged it overnight and used it until the battery was exhausted. It ran a very long time I didn't time it but it was almost twice as long if I had to guess. Normally I can do the steps and the upstairs and a little bit of the downstairs before the battery ran down, when it was new. With this replacement I did that but also the basement, basement stairs the whole downstairs and it was still going. I did all the corners and went over a few places because I wanted to run it all the way down before recharging. TLDNR? Easy to install, quality made and lasts a very long time, worth the price. update: 1/1/26 I've been using the new battery for a little while now. It's still working well and lasts a long time. The battery lasts pretty long. I tend to run out of steam before the battery does. I use to do most of the house on regular power and a few high traffic area spots on max. Now I can do the whole house then switch to MAX and do most of the house again. More often than not I finish before the battery is exhausted.

This is a great product and comes with everything you need to dramatically improve the performance of your vacuum. It even comes with a tiny screwdriver to simplify the battery installation. The instructions are clear, and the battery is a perfect replacement for the original one. I was noticing that the run time was getting progressively shorter before needing a recharge and this new battery completely solved that issue. And the filter replacement seems to give it more power.

Perfect replacement for a Dyson V-8. It took me 10 minutes to change the batteries on our Dyson V-8, and now its like a new machine. Better suction with MUCH longer battery life. The free filters was like icing on the cake - not necessary but greatly appreciated. Removing the old battery was easy after I watched some YouTube videos, and putting this new battery back in was even easier.

Easy to swap out. Works perfectly on my d7 fluffy. I have my charger set up on a stand for quick access and this replacement still fits it just as the old one did. I did notice the replacement has a thin rubber pad on the back edge that was not on the original. It makes it a tighter fit in the charging base, but that hasn't been a problem. I can't figure out what he purpose of the rubber pad is though. I hadn't noticed how bad my old battery was getting until I could barely run it 5 minutes before it would die. Swapped it for this one and now I have my vacuum back!! I can do at least half my house at once now instead of it running out barely after one room!

My dyson started shutting off after about 5 min of run time. Then I found these replacement batteries. I took a chance thinking this might help. It DID! Those dyson batteries evidently do not have a long life. This was a lot cheaper than their replacement and has been working great since installed. The kit comes with everything you need (even a screwdriver....it sucks, but works) and it's only a few screws to take out to install. My machine runs as good as new now. PS. Just make sure you're getting the battery for your specific model. Mine was for a Dyson V8 Animal

This battery was a great replacement for my Dyson V8. Installing it was easy and it fits perfectly with the original setup. I like that it works with the original Dyson charger, so there’s no need to buy a new adaptor. The 9000mAh capacity is the largest I could find on the market, and the run time has been really good so far. The battery indicator light is different from the original but it works just fine and does not affect performance. Suction is strong, and the extra filters are a nice bonus. Overall, it’s a solid upgrade and a great way to keep an older Dyson working like new.
