Dyson cordless vacuums are quite costly, so it is crucial to do everything you can to extend its service life to the fullest.
One way of ensuring years of service is to replace the battery when it starts showing signs of failure.
When it starts to flash red, or it doesn’t hold its charge, then it’s time to think of replacing it.
Fortunately, the task is simple and only requires loosening a few screws. I’ll show you exactly how to replace a Dyson V8 battery in this guide.
Tools you’ll need:
- Mini Philips screwdriver set with a rubber handle
- Replacement V8 battery
Step 1: Remove the wand.
Detach the wand to make the task of removing the screws less obtrusive. If the vacuum is plugged, proceed on unplugging it to prevent electrocution.

Step 2: Loosen three screws.
The other two are underneath the battery behind the dust container.
Make sure that the screwdriver fits, or you’ll risk stripping the screw. One way is utilizing a mini-screwdriver set, which has various size heads.
Use a screwdriver with a rubber handle, so it doesn’t slip. Also, get something with a thicker handle so you’ll have better leverage.
A screwdriver with a magnetic head will be a lot of help as the bolt will stick on it once its out.
Step 3: Remove the battery.
Once you’ve loosened all the screws, remove the battery. Place one hand underneath, so it doesn’t fall and hit the floor.
Place the screws on a metal dish, so you don’t misplace them.
Step 4: Reattach the battery.
Take the new battery out of the box and install it on the vacuum. Do steps one to three, in reverse order.
Attach the two bolts at the bottom first so the battery won’t fall then proceed to tighten the screw behind the handle.
Can you replace a Dyson V8 battery?
Yes, as you’ve seen in the steps and photos above, replacing the battery is a simple three-step process that requires a Philips screwdriver and unbolting three small screws.
How long does a Dyson V8 battery last before replacement?
The answer will depend on usage and how the user cares for the vacuum. I’ve had a Dyson for more than four years, and it holds its charge well. Consumers report varying levels of longevity; some say 2-3 years, while others say it lasted 1.5 years, so it varies.
One way to maximize the service life is to keep it plugged in. Dyson vacuums have a built-in system that prevents it from overcharging.
Where to buy Dyson V8 replacement batteries?
There is a multitude of options when sourcing V8 batteries. One such merchant is Amazon were numerous brands that sell OEM replacements. In some cases, some have higher milliampere ratings than the original so that it will run longer.
Of course, there is the risk of getting a dud, but these options cheap, and the good ones have good feedback from consumers.
Choices vary, I would suggest getting the largest capacity battery you can afford with an excellent rating of at least four stars from numerous consumers (the more review, the better).
You could buy an original battery from Dyson, but these batteries will easily cost $100 (and up), more than triple the price of OEM replacements.
