简介
This was a great little product that has seen a lot of use around my shop. But like several other B/D products the rechargeable battery does not last and the replacement has been discontinued. I found a few through some online retailers, but the cost was on the average around $36 plus shipping. Two ways to go with this, trying to either revive it by building a battery pack or to just dump it. Well, I am frugal, if I can fix it, I will.
你所需要的
-
-
Here is my 2 speed TS221 Ranger CD2000 that does no longer hold a charge.
-
Removed the 8 Phillips screws from the case.
-
All screws are 3/4inch long and therefore the location of the screws does not have to be marked.
-
-
-
-
The battery tabs or spot welded to the batteries.
-
They are in series, meaning they connect from the positive post of one battery to the negative of the next.
-
Here are the 5 replacement batteries. They are 4/5sub C batteries. This means the are 80% the size of a C battery. 1.3" (33.4mm) in length by 0.9" (23mm) in diameter. 5x1.2V in series gives 6V x 2000mah
-
-
-
Start off by laying the connections out. Again, negative connects to positive.
-
The tabs are thin sheet metal and can be cut with a pair of scissors. cut the positive tab of the second battery. The left over spot welded tab will become the solder point for the first battery.
-
Use flux between the connections.
-
-
-
Here is the completed first row of three batteries.
-
To connect the next row, it is important to remember that the negative from the bottom row continues to connect to the positive of the top row
-
Position the last two battery so that the polarity matches the way the connect to the back of three.
-
-
-
Solder the top two batteries together.
-
Position the batteries so they will match the proper polarity and do not cut the tabs.
-
To connect the bank of three batteries with the last two, leave the tabs the original length and solder those tabs together. Use some hemostats or alligator clamps to hold the tab while soldering.
-
-
-
Here is the complete battery pack On this image the polarity is marked for clarification
-
Install the new battery pack and reconnect all the cables using the battery tabs as connector
-
Cover the new battery pack with some electric tape to minimize movement of the individual cells. total cost for the repair was $13 and 2 hours of my time.

Very good job ! I will do the same with my older cordless 9049. Thank you .
I have a 9049. It will no longer charge much. It's such a good set. Is this something I can do? I am a woman and generally a little bit handy and willing but I don't know where to get the batteries and I'm afraid of getting things mixed up. I wonder if I could take it to a small machine repair shop and see if I can get them to do it. Thoughts?
@dianaverhulst it is very much the same to replace/rebuild the battery in a B&D9049 as in this guide. Not sure if a machine shop would do this type of work. Any good "Tinkerer" should be in a position to fix it for you. If you are uncertain or really stuck, I am in TX and would be willing to help you out. No cost (other than materials) to you. Not because of your gender but because I hate things going to waste. Check my about page on how to contact me.
What year is that b-d? I just found one in an attic.
