Rebuild a Dewalt DE9037 cordless power tool battery pack instructions

Step 1: Take apart Dewalt DE9037 drill battery pack

remove the six screws that hold the pack together

carefully pull apart the two halves

take notes as to where things are and how they go back together

have a digital camera on hand for documenting dis-assembly

Step 2: Remove Dewalt DE9037 power tool battery pack

carefully pull the Dewalt drill battery pack out of the holder

Step 3: Document everything

as you pull the battery “pack” apart

take pictures and draw pictures of how the 12 batteries are packed and connected so tightly

Step 4: Buy replacement batteries

Search 1.2v subC batteries (1.2 * 10 = 12)

find the best price for 10 batteries

when you place your order make sure you have measured your Dewalt DW953 Drill Battery cells and are getting the correct “physical” size

buy with or without tabs

without tabs is less expensive and the following steps will show you how to make your own tabs

Step 5: Diagram the replacement batteries connections

you will notice after folding and unfolding the string of batters

that the 10 batteries are wired in series pos-to-neg, neg-to-pos and so on

use the gummy insulator that you pried away from the top and bottom of the batteries to draw a template

then use a coin to complete the circles representing the batteries

draw a diagram looking at the batteries from the bottom

then draw a diagram of the batteries from the top

note each connection and how the battery tab is oriented

number the batteries on your diagram

while you are waiting on your new batteries to arrive in the mail

practice refolding the old Dewalt DW979 Power Tool Battery string and placing it back into the holder

Step 6: Making power tool battery tabs

the battery tabs, as you can see, need to be flexible

one very good source of material for making battery tabs is an old computer cable with an outer mesh

this is an old Firewire cable cut into small strips with the innards removed

the mesh can be squashed flat and take on solder very well

you will need eleven strips

cut extra just in case

put some flux on both ends and tin the ends with solder in preparation for soldering to your new batteries
