The standard size version of that Li-Poly that they sell is only 1200mAh which is 150 less than the standard UTStar. Which doesn't make sense, because Li-Poly should be about 20% higher than a similarly sized Li-Ion battery.

There are more things to be concerned. LiPoly batteries have a higher full charge voltage then LiOn. The charging circuitry in the 6700 is for the original LiOn battery and I am not sure it is "LiPo aware" and adjust accordingly. The result is you will not get the rated capacity of the LiPo battery since it will never be fully charged. On the plus side, you will have a lighter battery.
the tech is there for phones to have battery power management for different cell structures but the 6700 does not have this functionality right now. poly technology for mobile devices were in draft stages when the 6700 was thought of, but UTstarcom could update the management system in the 6700 via a firmware update IF... IF the 6700s management system is designed to do that.. which i doubt..
so .. aau007 is on point.. .the 6700 should charge the poly battey but it will not efficiently use the additional increased capacity because it does not have the software that will tell it HOW to correctly charge it... it may even not charge at all...
LOL. Looks like a moot point/link for us both!
I do wonder why the same seller is selling that kind of variety at the same prices for higher and lower capacity batteries.
Thanks all for the information about them. I was just considering getting another standard and/or extended battery and this helps with the decision-making.

LiOn and LiPoly charging algorithm are very similar. LiPoly battery can be used in place of LiOn but not the other way around (provided the device is not EXTREMELY voltage sensitive). LiPoly has a higher full charged voltage than LiOn.The catch is when you use LiPoly to replace LiOn in devices that is not chemistry aware, the LiPoly battery will be charged using the same LiOn charging algorithm. End result is that you will only have less than 90% of the LiPoly rated capacity useable. In the 2 links on ebay, the 1400mah mentioned by seller might be the rated LiPoly capacity while the other is probably what the seller mean you will get out of the battery when use and charge in the 6700. Thus the difference between 1200mah and 1400mah.
Will they work, yes if made correctly,
Will the phone charge them, yes if the above works.
Will you get the full rated LiPoly capacity? Nope.
What capacity should you expect? 85% to at best 90% of LiPoly rated.
Any advantage on using those? LiPoly cells are lighter than LiOn cells, cheaper than originals.
Should you get and use them? Entirely up to you.
no, lithium poly batteries don't explode like lithium ion because they are not encased in a metal "box" (i.e. pipe bomb). They are normally soft or have just a weak plastic casing, so they don't "explode", but they can swell and potentially "vent" hot gas and melt everything around it on the extreme worst case situation/failure mode.

This video might change your mind. http://www.liposack.com/LipoSackv.wmv
That's the result of overcharging or charger's failure to detect a fully charged LiPoly battery. Shorting out a fully charged LiPoly battery may cause similar result. Keep in mind the LiPo battery in the video has no casing.
Well I took the plunge and bought one. My battery is sucking at life and I was going to buy another one this week anyway. I figure I will try it out and pay attention the first few charges to make sure my 6700 doesn't spontaneously involute. I will let you guys know how it works.

Well, I guess I should have worded my statement a little better. I have seen those videos and have witnessed the effects of a 14.8v 6150 mAh Li-Poly battery "vent" due to an over charge condition. Completely covered a 20x30 room in nice layer of soot. The battery never "exploded", it just vented and melted everything around it. Lithium burns at like around 1300 F I believe.
Anyway, I guess they will "explode" under the extreme conditions in that video, but still not like that of the li-ion. There isn't shrapnel and since the poly does have a chance to vent before this "explosion" it should actually take longer before it does compared to a li-ion....but probably with more energy/heat when it does though. I will say that with the proper protection circuit built into batteries available today, these events should NEVER happen, like I said *with* the proper protection circuit.
In the context of this thread, this type of failure would not be seen on our phones using li-poly batteries as these failures are caused by applying too high of a charge voltage. And the worst case that I see happening on our phones is that the batteries don't get fully charged.
Just to let everyone know I have been using a Li-pol battery in my 6700 now for over 2 months. I have had no problems at all. It is a 1500mah battery shipped from the UK (not ebay, a legit reseller). It is the same size as the stock battery, which I wanted. Paid about $20 for it. I contacted the seller and he claimed that it would work with my current chargers as well. Did without a problem. I get much better life our of this battery than I ever did with a li-ion battery, including an 1800mah battery bought after market. About 3.5-4hrs talktime with bluetooth, 4.5-5 without. After several short conversations thoughout the day and a few cardgames even checking email with wifi a couple of times, most days I end with at least 70% battery remaining. Usually I do not even charge over the weekend. Thought everyone would like to know this bit of info. I will have to look up the address to the vender if anyone wants it.

I'll bite. I'm due for a new battery, and don't like the larger size of the Seido extended. Did you order it online?
