My 901 auto battery was stuck on, and following a forum member's advice, I went out and got some PGA to soak it. I googled around to see if I could find some more specific instructions on how soaking it (how long, etc.), and I came across a gem- unfold a paperclip and stick it all the way through the battery. I did it, it tripped the switch, and now it works again!! When my replacement batteries come, I'll probably soak it just to get the gunk off, but this 10 second fix will at least keep me from resorting to analogs for the next couple days. BOOYAH!!
