Review: Makes my old tools work again - I've tried this on all my old dewalt stalk type battery tools. All tools work again with this adaptor now. The price is a bit excessive but if these tools keep working with this adaptor then it's well worth it. The adaptor came in proper plastic retail packaging with instructions so I have no doubt this is a genuine dewalt product
Review: Works as Advertised - Despite a number of negative reviews, I found the adapter easy to insert and remove. It is easier if you take the battery out of the adapter before either inserting or removing the adapter from the tool. I have tested the adapter on a number of my old 18V tools and it works perfectly. Don't forget to remove the battery from the adapter when it is not in use (either on or off a tool) as the adapter contains electronic circuitry which will eventually drain the battery. This is easily achieved if you remove the battery from the adapter before removing from the tool.

## Features

- Allows for use of 20V MAX* Lithium Ion batteries in most 18V DEWALT tools
- Requires use of 20V MAX* DEWALT charger
- Do not use with premium DEWALT batteries in DC970 or DC759 tools
- This Adapter will not work with 20V/60V FLEXVOLT Batteries
- The DCA1820 adapter is compatible with the following batteries only: 1.5 Ah, 2.0 Ah, 3.0 Ah, 4.0 Ah, and 5.0 Ah XR

### ⭐⭐⭐⭐ transforme parfaitement une batterie NI-cd en Li-on dewalt
*by C***N on 21 February 2024*

Fonctionne très bien m'a permis de remettre en circulation une scie sauteuse et une scie sabre marque Würth (oui il y a 20 ans c'était du dewalt déguisé en Würth). fonctionne également avec des anciennes machines dewalt. seul bémol, non compatible avec les nouvelles batteries Powerstack dewalt, les 2 ergots de chaque côté de l'adaptateur empêche l'engagement de ce type de batterie. après j'ai également acheté une copie chinoise à 20 euros, qui à l'air de fonctionner aussi, mais en tant qu'artisan, j'ai préféré prendre la marque Dewalt (certes 6 fois plus cher), en espérant avoir une garantie de qualité, j'espère que je ne me suis pas trompé, l'avenir me le dira. si ça peut aider certaines personne c'est compatible avec les anciennes machine qui ont les batteries réf.DW9095, DE9095 et certainement d'autres références que je ne connais pas. Merci d'avoir pris le temps de me lire. Gaël
