    I'm not exactly sure where you're getting the extra 2 from

    You will count 3 + 3 + 2 + 2 + 2

    (The last 2 being between the two rows of 3)

    dewalt use 10 18650 series to get 18v

    In many cases, it's 5 in series (or ten total: two parallel banks of 5).

     

     

    But in my battery, I can count 12 cells in total. Linked two by two in parallel, that means there are six in series!

  3. I've opened my DCD925 battery the other day...it has 12 18650 cells. I guess it's 2P6S.

    Other tools use 5 cells in series instead of these 6.

     

     

    Do you happen do know how many cells the other Dewalt lithium batteries use?

  4. I bought a non-functioning drill for $6 at the flea market.

     

    Turned out to be the brushes, which I'll order soon (the eBay seller is on holidays for the moment  :-D).

     

     

    There was a bit of corrosion on the rotor and stator:

    I got it (mostly) off with contact spray and elbow grease:

    But the rotor's pinion seems pretty dry, should I put a dab of grease?

    Ideally, should I remove the gearbox' cover and clean/grease the gears?

     

     

     

    Also, there are some pretty deep marks on one side of the stator:

    Should I be worried?
