Do any websites make an extended battery for the prophet platform? And are there any places where you can buy mobile USB chargers for our phones so we can charge them with AA batteries if we don't have access to a power plug and/or PC? Thanks!!

You can buy an extended battery (1500ma) from online retailers for the Jam/Magician, I got mine from MMB (not listed anymore) it is exactly the same as for Prophet...I've done it. AA>USB>Prophet...don't know, I don't know why you would want this unless you were in the wilderness with no wall outlet or car
Jam and JAMin batteries are not EXACTLY the same
Like lots of others, I bought a spare JAM battery with my JAMin. However, whilst it fits and works, they are not exactly the same. On the side opposite the power connections, there are two shallow recesses. These are designed to allow two small ridges on the case to snap into them, thus holding the left side (facing you) of the battery in place. For whatever reason, these recesses are in slightly different locations on the JAM and JAMin, meaning that the JAM battery does not lock in as the OEM battery does. It thus relies on the back cover to retain the battery in place. As I say, it works but....

Re: Jam and JAMin batteries are not EXACTLY the same
My original Jam battery didn't fit properly in my Jam either. If I dropped it, the battery would come loose just enough to cause a reset. I solved this problem by inserting a small sliver of cardboard on the opposite side of the battery from the contacts, which I cut from the flap of the original Jam box I used the same method with my Jamin just for safety. I've had no problems after using this fix.

Hi,
I used to have a 1800mAh battery for my JAMin (an aftermarket Ebay one). I made the mistake of sending my device for repair (screen replacement) with that battery and got a 1200mAh battery back (well - I should have seen that one coming). To cut a long story short - ordered another one. This one looked OK so I put it in my JAMin and it was OK for one day. I then put it to charging (second charging) and suddenly the device had a soft reset and would not come out of splash screen. I picked it up and the battery cover felt hot. I opened it and the battery was very hot on one side. Took it out and put it in a safe place but it would not cool down. I was concerned it will catch fire so I opened it and disconnected one wire going from the battery to the PCB inside. It then cooled off (the PCB was hot - not the LiPo cell). I connected the wire again and it seemed to be OK now but I was not willing to risk it again. I opened one of the 1200mAh batteries I had, thinking about switching just the control PCB. The original battery had a better looking PCB (more professional looking) so I connected it instead of the original PCB. I put the battery back in but now it shows 0 capacity all the time, will not go out of splash screen without a charger connected (WinCE low battery protection??). I know the control PCB has a device with EEPROM and RAM inside so my thoughts are that the RAM must have had a reset when switching cells and needs some refreshing. Any one knows how to do that????
Thanks,

Just got my new extended battery yesterday, and so far it works ok.
But now I need a new carholder of course, because the old Brodit mount wont take my Uni anymore now that it has become thicker....
Anyone found a solution to this, I prefer to have it in laptop mode in the car, I use TomTom a lot!
/HM
The Exec I have with expanded battery still fits in the Brodit holder, OK so its not quite as easy to get in the holder, but it's fine once located - Mike
Mine doesn't at least I don't think it does, I haven't tried to actually force it in though, did not want to ruin the holder, can you tell me how much your Uni has gained in thickness with your extended battery?
Mine has grown almost 6 millimeters, but if yours is the same increase, I will definitely try and force it in after all.
Cheers
/HM
Oh, I forgot to ask, can you still use the socket for the charger?
At least 6MM the battery is a LI-PO cell 3150mAh device (part number PU16A), it is a tight fit in the Brodit mount but it will go in, and yes I can still use the charger cable - Mike
is the extended batter alot better ?
as i'me getting an Xda Exec this week
I use the extended battery when away from home with the device, the main reason is Internet access, the battery gets hammered when connected via 3G so the extra weight and capacity is worth it for me, not for everyone though - the Exec is a lump to start with add the extended battery pack and forget the shirt pocket to carry it in! - Mike
Hi there!
Does anyone know of a way to operate the Universal solely on A/C power when there is no battery inserted?
I often use my universal as a WLAN media player in the kitchen. It just sits there for hours playing music and I would like to remove the battery from it during this time to extend overall battery life.
Unfortunately the device does not turn on when there is no battery inserted.
This should be fairly easy, if I understood well, you don't want to let the battery in the universal (even if normally the battery chargers apply a tickle current charge when the batteries are already charged to mantain it fully charged), so you just need to connect your power supply directly to the uni's battery contacts -BEWARE the power supply MUST be 3.7V REGULATED / 1A minimum current-.
Personally, I do not like to change the way the objects are, so I would try to keep it like this in this case, this means, no extra holes in my PDA, no extra connectors, etc. so you need a pair of mini alligators clips or miniclips to connect your unit to the power supply, be sure to verify the correct polarity, it's clearly written in the battery's contacts.
Alternatively, there should be a way of doing this by using the uni's own battery charger through it's own mini USB connector, it's necessary to cheat the PDA and let him "think" he's got the battery inserted, this should be fairly easy to do also, but I'm out of my work, so I could provide a complete solution like this until late april.
bye

Why don't you use an old battery?
I use this way in this particolar circumstances!

That's what I used to do, unfortunately the old battery I have is so worn down by now it won't even support the boot process any more, and the A/C power regulator kicks in only after basic I/O drivers are loaded on the device.
Since the old battery dies before this process completes I can't use that any more.
I don't believe the Universal's "battery detection circuits" are all that complex, in most modern electronic devices they can be fooled by simply bridging some of the connectors in the battery bay.
I don't know if this is true for this device also, however. So I was wondering if anyone else ever tried before I toast my PDA...

Oh.. I understand.. Sorry..
Well: be careful if you try to solve in other way..
What is the backup battery used in the Hermes? It looks like a LR521/SR521, but I heard that PDAs often use rechargable ones instead of normal ones. Both sides of the battery has a nickel plate welded onto it, and I only see "SII JAPAN" very faintly etched onto the +ve side of the battery after removing the plates.
Im having the same problem. Does anybody know the exact model for the battery? I don't know what to buy
Hello Gentlemen,
I have charging problem with mu Wizard Qtek 9100... its not battery issue I have 2 working batteries...
The phone starts only when the charger is not pluged in..
Otherwise RED light is shown and the phone refuse to start so I need to remove the charger and the battery and then put the battery back so I can start the phone...
When the devise has started already I can plug the charger but the Windows is not showing ORANGE light and is not showing charging....
The device acts very wired and is turning off with no reason...
This happened when my charger burned up while charging my device...
Now I have no sound,the device is SIM locked and is turning off sometimes for no reason....
I believe it is a hardware problem I guess I need new mainboard?
Please advice if this could be a software issue....
The device is G4 IPL/SPL 2.26.0001
Please advice,
Thank a lot...
Regards,
Mitko B.
Battery problem
Hi,
I know old post, but it may help somebody.
It is possible that your windows has switch off the battery charging circuit for some reason.
You MAY be able to get it working with the following trick:-
You need 3 x 1.5 volt AA batteries, some wire and 2 pins
You need to join the batteries together in series (i.e. end to end)
Next make a negative lead from the negative of the battery pack to one of the pins.
The make a positive lead in the same way.
Open the battery cover of your Wizard.
Connect the USB charging cable.
Put the negative pin you have just made into the gap between the battery and the charging pins in the Wizard - MAKE SURE YOU ONLY CONNECT IT TO THE PIN NEAREST TO THE USB PORT.
Now comes the tricky bit - take the positive pin you have just made and touch it on the charging pin which is NEAREST to the power on switch.
If all goes well the charging light on your Wizard should turn orange indicating that it is charging.
You might have to try this a few times, I was never sure if you had to keep the external battry connection on for any length of time or just a quick connection would do the trick. I suppose it depends on the state of the Wizards battery.
This is NOT my work! I do not want to take credit for something that is already documented on this site as it helped me get my battery working again.
Regards,
John
thanks a lot!
saved my wifes phone. Is this problem (happend twice already) something that I can address with a new rom, anyone knows?
I also have the remove the battery go back to Feb2006 issue. Device is off warranty by a few good years. Is it something an experienced electronics person could try (without destroying the phone that is...)
Cheers
V.
Worked for me too
I had just bought a new battery for my Qtek 9100.
This one:
sku.23974 at dealextreme.com
My 9100 had been dead since 2006 (because the battery was dead ...)
And i got a new phone.
but i tought it was to good to throw away, so i bought the new battery.
But i did let it run out of battery, and it would not take the charge.
but this trick did the job
Thanks
Hi all,
Just wanted to sign up to say thank-you - I chanced upon this forum while seeking a solution to the same problem.
I'm happy to report that the 'jump-start' works perfectly!!
I actually used the slightly different method, described in another thread on this forum:
Take a USB-to-Mini B cable. One that you won't need ever again.
Cut the Mini B end off and strip back the outer casing. Inside is a wire mesh and within that a foil lining. Pull these both back.
Now find and strip the black and red wires. The wires are thin and this is a fiddly job, especially if you have large hands, so this works best if you screw the exposed wire strands up into little balls.
Remove the battery from your Qtek 9100 (or whichever model it is). Pay attention to which pin goes to which contact and so identify which ones are the positive and negative contacts on the battery - It is described above in Heinkeljb's post.
Now, plug the USB into your PC (which should be switched on and running) and connect the black wire to the negative (and red to positive) contact on your battery.
Hold for a good 30 seconds.
Now reinsert the battery into the phone and attempt to charge.
You may need to 'jump' your battery a few times....
Once again, many thanks to teh lovely people here for saving my beloved Qtek 9100!!!!!
