Hello, I have a portable Milwaukee Sawzall, its works wonderfully when trhe batteries are charged and is useless when they are inert. I have several of these batteries. Eventually they all died. Recently in a passing conversation I was told that with a new 9v battery you used it to jolt to life these old batteries and then they would take a charge once again. Has anybody ever heard of this ? Is there some specific information with this regard that I could download or write down instructions? These batteries cost a lot and I won't buy more so I hope someone reads this who knows this information. Thank You in advance.
