What’s the difference between OEM (Original Equipment Manufacture) batteries and aftermarket batteries?


With such a big difference in price, cheap batteries that are not OEM are quite an attractive option, but should you buy them over OEM? Let’s take a look at the pros and cons.


OEM Pros

  • Better quality control
  • The Ah stated is what you get
  • Perfect fit on tool
  • Proven to work well with OEM power tools


OEM Cons

  • Can be very expensive


Aftermarket Batteries Pros

  • A Lot cheaper than OEM
  • Some can have similar features to OEM, such as battery power level indicator


Aftermarket Batteries Cons

  • Ah advertised is not what is always supplies, if you buy 5Ah, you may get 4Ah in a 5 Ah shell
  • Quality control won’t be as good on aftermarket compared to OEM
  • Battery cells may not be as good as the originals


Aftermarket batteries have a place in your tool box and if you are someone who requires more than one battery, having a few cheap aftermarket batteries maybe beneficial. However, if you a an DIY enthusiast where one battery is enough, it is probably best to invest in DeWalt OEM batteries.
