Fix for 18v Snap On Cordless Battery ? CTB3185

[BigV]

I have a Snap On 18v CTB3185 battery that goes with my cordless Snap On impact. I have a barn to work in with no electricity, so the little Snap On is a nice toy when I am lazy and don't want to turn a wrench.

I get a voltage reading of 1.9 volts on it, and the continuity check doesn't even register- it does not come up with a figure nor does it beep(even intermittently). I did not take the battery apart, it does not appear the clips are broken. I have another battery that is good that confirms the charger is good, and so is the tool.

Even if it only gets a little more life out of this battery, if there is any thing I can do to get the non-working one, working, I want to do it.

Thank you fellow tool junkies.

Is the battery case sealed or can you open it? Rebuilding the battery is a option, Batteries Plus does rebuild them but are IMHO expensive, here is a link to google:

It is a 2005 MIJ battery, so I can open it. It has a row of screws on the bottom. S-O used to sell a recase for this style. I've heard rumors that the newer batteries are sealed and can't be opened. Don't know if that is true. Seeing as how I can't afford a new battery, I don't want to find out.

Thank you very much. I may try the 12 volt "rebuild" and if that doesn't work- send it off to MTO and get it fixed for $45. I've heard these batteries are very expensive from S-O.

If it is a ni-cad battery, couldnt you zap it back to life?

I was reading up on this online.

could try 2 car batteries to get it going.
