C3200 Has Constrain On Battery? Options

[chyang]

I bought 2 compatiable batteries EA-BL08 from http://store.l-f-l.com, and the result is they cannot be used in my newly bought C3200. When it is plugged, the LED will blink, and refuse to work in the PDA. I then charged it in my spare charger. Even after the batteries are fully charged, the PDA refused to work with it.
I then bought another one in China, the factory are building compatible batteries for Sharp's PDAs, also the same type: EA-BL08, but it cannot work with C3200 either.
Has anyone heard of the constrain? I don't know whether it is the problem of the battery or the constrain of C3200. Has anyone successfully used compatible batteries(EA-BL08) with C3200?
Thanks.

I bought one also (Cameron Sino - 2000mA). It didn't work in the 3100. However, when I checked it with a tester it had adequate power.

Suspecting lack of connection (the flashing ws the same as with no battery installed) I folded some aluminum foil and placed it in the three conneting points. It worked, but I knew that was a DANGEROUS solution. I was at risk of the foil coming out, shorting, fire, etc.

Plan B: I took a pocket knife and carved away a little of the plastic from the bottom side of each point of connection (keyboard side of the battery). I just removed some of the sharp edge. With that modification it made positive connection and no more flashing light. The battery seems to work great so far.

I had a battery with similar behaviour. What I did: I just flowed some soldering tin onto the pads (be careful not to heaten up the contacts too much!).
That made them a little thicker and now they have contact.
Works great so far.
But as always: Do it at your own risk!
