Hmmm. I've been running two manuals from Shawn for about 2 weeks without a problem. How long was it until you had the button problem?
Sorry AJAY666999, didn't mean to hijack your
thread.
I was using it daily for about 3 weeks and the button had stuck twice during that time. Its an easy fix, just put a fingernail to the button and pull out the part of the button that got stuck in the battery.
Anyway, sometime during the 4th week of use, I used the battery all day once and it ran out of charge, I placed it on the counter and switched out to my other auto 401 battery. a little while later my wife said..is this supposed to be on? I looked over at what she was pointing at and the blue led on the end of my manual was on. I pushed the button and it changed nothing, the light stayed on. I tapped it, dropped it on the counter a few times, shook it, but nothing changed, light stayed on. I even removed the rubber button, nothing.
The light eventually went off and I attempted to recharge it but nevertheless it was dead...permanently.
On a side note...before it died, the manual 401 was my FAVORITE battery. I freakin loved it.
oh well.
