Dead backup battery, clock resets itself when main battery is removed - 8525, TyTN, MDA Vario II, JasJam General

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

Jamin Extended Battery

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.

Outsmarted by the battery

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,
Nir

Extended Battery Problems

I received an extended battery which I ordered from ebay and i am having problems with it. The stated capacity (of 2300mah) is true however i have to remove and re insert the battery to be able to use it. E.g. I charge the phone fully and use it until it shuts down, i then remove and re-insert the battery and i still have over 50% left. If i have 80% left and i remove and re-insert the battery it will jump back to 100%. I have tried fully recharging and discharging the battery. I have also tried changing to the latest official rom for my provider which lists extended battery support as one of its features. I have seen comments in some of the extended battery threads with people having similar issues however there are no solutions mentioned in them. Does anybody have any ideas on how to fix this?
Something you will have to live with. HTC fix works with their official batteries AFAIK.
I opened up the battery and i found it is actually 2 batteries stuck together. So im pretty much out of luck for a software fix. I guess this will just become my spare battery.

[technical head on]
That's what a battery is; more than one cell.
Wire identical cells together in a row and you combine the voltage but not the capacity.
Wire the identical cells together in parallel (ie + to + and - to -) and you combine the capacity but not the voltage.
So take two 1200mAh lithium cells and wire them in parallel and you get a 2400mAh battery.
The original ROMs were designed with a 1200mAh cell in mind, so their power meters presume that's what you have. If you take out the battery and plug it back in, it resets the power meter. Both cells are being used at the same time, don't think it uses one then flips over to the other.
Try a newer ROM and see if that sorts you out.

My phone randomly shuts off..

I've noticed that when ever I squeeze my phone, where the battery cover is, it shuts off. Has anyone else experienced this or am I just the only one?
Sent from my HTC Vision
Don't squeeze the phone? If you look inside your battery compartment, there are tiny gaps between the battery and the phone. I can only assume that these gaps are for the battery to expand when heated up during use. I think you're in the situation where you hold your phone in a certain way, you are actually temporarily disconnecting your battery from the terminals which is shutting down your phone. A ghetto solution is to pad the inside of your compartment with paper =p
Also check to see if your battery is swollen. If it is then it may not be sitting very well in the housing causing it to move and disconnect from the contacts when you flex the housing of the phone.

Also, clean the contacts with a little rubbing alcohol on a q-tip

the phone works but sometimes after moves it shutdown..how can i fix this? its because it has bad connection or what?
Does anyone know where to find this battery to buy new?
also can i replace the battery connector with battery connector from another phone with 3 pins?
Thanks in advance
Well find alternatives on ebay or use that battery. Use hot glue to secure battery temporarily if loose connection occur. Remove useless app and less frequent charging will prolong its life or contact any eletronic/mobile shop. Hope this helps.
Dude it happened to me. I got a symbian phone whose battery was 7 yrs old but still it worked briliantly. Although i find a battery but its size was small and i used hot glue to firmly held it. It worked well. But last year it got stolen. I miss that unique phone. It was preloaded with band &oulsfeng amplifier. Checkout samsung SGH-i450 on internet.
