My first Dyson vacuum the battery was not replaceable.

I wasn't sure about buying an after-market battery for my Dyson but for the cost difference I took a chance, and I am glad I did. This battery runs the vacuum much longer than the original battery. How much longer? I don't know. I haven't run it out of charge yet.

Worked great at first. After three weeks it doesn’t at work at all. Wish I would have kept my original battery at least I could use 5 minutes at a time now vacuum is useless

After troubleshooting various problems with my Dyson, it was clear that I needed a new battery. So glad I switched it out because this battery greatly extends the vac run time between charges...better than OEM battery!

Easy to install. Should replace filter along with battery change. It will run like a new one.

Great replacement battery for Dyson vac.

No instructions, but I was able to figure it out. I took it apart so I can put it back together. Looks just like the original.

Didn’t realize how easy swapping out the dead factory battery was, or I would’ve done it sooner. The new battery installed the same way as the old one, and the charge lasts a lot longer. Can do all the hardwood floors in my house on one charge.

The battery worked fine at first, but after several months it suddenly stopped working. I should have sticked to OEM
