Joelson Canadian... , I am well aware of the 1 year battery replacement warranty and the Bosch Provantage Plan. I've now had these tools for 3 years and have no coverage left at all. I certainly got my money'* worth though. Of the 15 or so 14.4V cordless Brute Tough Driils we own, I've had 18 free drill replacements, somewhere around 25-30 free repairs, and many, many free battery replacements, lol.

We beat the crap out of these tools here. Maybe that'* better said as; we use them to their full potential and then some. We are such heavy industrial users that Bosch has sent their tool engineers from Japan to our shop to get our input on improvements and so that they can see a real heavy industrial use in action.

Since these are now out of warranty, I now repair the drills here on my desk.

Now, I need to refresh these batteries instead of buying another 20 or so at the "cheap" price of $75 each. 75 x 20 = 1,500. See why I want to do what I'm attempting?

$75.00 each Mike? Are they more expensive then the $50.00 Dewalt 18 V XRP on Ebay?

OK Frank, fair question. Since you asked, I searched a bit. Normal lowest pricing, even at ToolBarn and other bargain tool outlets is $52 plus shipping. I did find a guy on ebay, that is listing some 14.4v Bosch "replacements" for $30 shipped, but I can't tell if it'* exactly the right one nor if they are new or even if they are just knockoffs.

When you consider that most places are selling them for $52 to $75, I would have to try one out and ensure they are correct. Of course, if they are, then that helps the cost equation a lot.

But I still want to know how to fix these. The recycling equation is crappy on these packs, and I'd much rather refresh them than toss them out.
