Well I love my Black and Decker FireStorm 18v combo pack but the down side is it’s several years old the batteries died. I have been looking online for over a year now for replacement batteries and refuse to pay $60+ a battery or 140+ for 2 (upgraded batteries. Really your normal 18v 2 battery/drill combo pack is only 59.00….. I don’t want a new drill though.
So I went to my local harbor freight tonight and noticed that they have a 18v battery pack (Chicago Electric Power Tools – Item#68860) and it struck me just how much it looked like my B&D battery pack. So i used my 25% off coupon and picked one of these up total was $11.00

Side by side comparison
First thing was to take them apart and see how the layout of the batteries….. (Why look at that they are the same configuration except for the plug….
So now to swap the batteries, simply switch the cases, and move on to the next step….. since this isn’t plug and play it did involve a soldering iron. I had to solder the leads on the new wires.
You will notice that the leads plug into the black plastic part on top of the battery (MARK the postiive terminal, mine was the white wire and the top prong (pictured above) Always check with a multi meter).
After assembly here is the old battery voltage and the new battery voltages.
(Old battery has 1.79 volts left)
End result: (New battery on the left and the old one sitting on the right ready for disposal via battery store)
