Full Version: C3200 Has Constrain On Battery?

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.

Hi Chen,

we had a lot of reports from customers that some fake batteries
won't work with the SL-C1x00/3x00 series. So we can confirm
that they're not compatible for these Zauri (behaviour of these
batteries is the same like yours).

But we can confirm that the Rowa batteries (the EA-BL11 type)
works with the new Zauri.

With all the news about the Sony batteries in Dell and Apple
laptops in mind, we would strongly recommend not to use
batteries from unknown companies. Just a hint.

hi, Marc:
Thank you very much for your valuable information. I will try to return it if possible.

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.

Thanks Mark, you shine a new light on my poor batteries.
I have also tested with a multimetre, the voltage is high enough to power the Z. I also suspected the connection, I scraped the connection point with some knife to remove the oxidation stuff, but I haven't noticed it cannot touch the connector of the Z.
I will have a try later.
Thank you very much!

hi, Mark, your approach works. I carved a little and placed it in the PDA, it doesn't work. So I carved a little more, and now it is working in my PDA.
Thank you very much! smile.gif

You are most welcome. I hope others get the message as well. It is a SIMPLE fix once you know what is going on.

These fake batteries may be just as good as those from unknown companies (ex. Dell and Apple who used batteries from unknown companies like Sony & now Panasonic). smile.gif

i am inclined to belive that the problem isnt with third party battries on the dell and apples (as they wernt third party) but that it is due to heat being acumulated near the battery

as we all know lithium is one of the most highly reactive elements known to man (potasium bieng first) and is never found in its pure form because of this. even heating slightly is a bad idea and it dosent supprise me that when a processor that can pump up to 60W is next to a mass of highly volitile chemicles that thier would be a tendency to explode

the saftey features in litium battries do not extend to overheating as far as i am aware as it is next to imposible to prevent against it. stoping the thing from charging will only work (thats the normal protcection) will only work if the battery is the source of the heat.

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!

I have just read in a magazine that the Sony cells of these battries had a failure in production: Small metal parts got between the Lithium and the other electrode which caused an internal short-circuit and thus internal overheating.

Unbelievable! Works like a charm. Took about 3 minutes.

Thanks so much for this.

Now I'm going to do some battery life tests before and after replacing the microdrive with flash.

I bought two extra li-ion batteries from ebay for my collie. They were from China, but under their brand adhesive it was written that they were made in Japan.
They work well, like the original sharp and the prize is smaller.

Another globalization issue.
