Are Stanley Fatmax Batteries Compatible With DeWALT?
Many people will know that DeWALT is owned by Stanley Black & Decker. For this reason, you may well wonder if the batteries in their power tools are cross-compatible. After all, they are made by the same company so it would make sense, but does it hold true?
Are The Batteries Compatible?
No, they are not. They used to be though! Stanley Fatmax has recently launched an updated range of power tools under the V20 brand.
These power tools and batteries are not compatible with DeWALT power tools and batteries.
Above you can see an example of the new V20 range of power tools.
As a side note, I absolutely love this range of tools. For me, they offer the perfect medium between performance and price. If you are interested have a look at some of my reviews of the range such as:
- Stanley FATMAX Drill Review
- Stanley FATMAX Brushless Drill Review
- Stanley Fatmax V20 Cordless Random Orbit Sander Review
So I’m afraid you are stuck and cant use these batteries between tools so you might need to stock up on some new batteries!
Trying to use a Fatmax Battery in a DeWalt tool
So just to show you that they don’t fit here you can see me trying to fit a Stanley Fatmax V20 battery into a DeWALT drill.
And in the below image you can see why they won’t fit together. There is a bit of plastic on the battery that stops it from sliding into the DeWALT drill.
Older Fatmax Tools
This V20 range of power tools is actually the second iteration of Stanley Fatmax power tools. The first-gen did apparently have cross-compatibility with DeWALT batteries and tools.
I say apparently because I never owned one of these older models so never got the chance to test this for myself. So I have to rely on reports from other users.
The reports from other users though are that they definitely do work with DeWALT batteries.
Adapters
The internals on these batteries are very similar, to be perfectly honest this is really the case for all power tool batteries.
They often use the same brand of battery cells, with just the PCB boards being different. So sometimes you can find adapters, and you can for a lot of the big brands. Unfortunately, I am yet to find an adapter between Stanley fatmax and DeWALT.
