My T630 are orginally equiped with a Li-Polymer battery.
Many postal-order stores sell Li-Ion and Ni-MH battery to mine T630 and said that Li-Ion and Ni-MH are as good as Li-Polymer but much cheaper.
What is the really difference between these batteries?

Personally I would advice to stay away from cheap chinese batteries, you might end up harming your phone and in extreme cases even yourself.

Li-ion is as good as li-pol, but Ni-mh is not so good.

Li-pol is thinner. T28 was probably one of the first ericssons to have Li-pol.

I said:

"stay away from CHEAP chinese batteries"

and by that I mean batteries without SonyEricsson aproval.

One would be very ignorant to suggest not buying any stuff made in china, cause most of the stuff nowadays is made in china. It all comes down to quality control, most stuff carrying decent brand labels has been controlled but the cheap s**t mostly hasn't.

I don't agree - some batteries are as good as original ones, some even better! I never had a problem with non-original batteries. SE just wants to make more money selling their batteries [too] expensive. Read this: http://www.esato.com/board/viewtopic.php?topic=87515&start=0

AFAIK, Li-ion or Li-pol are practically the same in terms of performance and size. They merely use a different medium. Li-ion is more stable but Li-pol is getting better and better nowadays and is also much cheaper to mass produce so manufacturers prefer them. Ni-MH is a relatively old technology and for the same size as a Li-based battery it holds less charge and generally has a shorter life.
resistance is futile.

It's not matter of size, but weight, li-pol are much lighter than other 2. Buying non-original battery is lottery, and the odds to get something good are small.

blackspot I think you have it backwards...

LiPol batteries are more stable than LiIon.

LiPols were developed to solve the inherent unstable nature of LiIons... at the slight expense of charge capacity/weight. (Supposedly this is what causes those exploding batteries that we hear about... something with the gas vents required on LiIons)

LiPols have the advantage of being lighter however... when a couple of mAh isn't an issue, you can get LiPols a lot lighter, and thinner than LiIon batteries.

If maximum capacity regardless of weight is what you need, then go LiIon... they're cheaper too.

If weight and size are priority, get the LiPol battery.

You can read more info in the link posted above.

To be honest, unless you have an old Ericsson T28, T29, T39, or their R counterparts... LiPol won't be such an issue over LiIon. You won't notice the size difference at all, and the weight isn't that big a deal (I think it's a couple of grams)

On the T39 and R520... the size is noticeable... the LiPol batteries for these phones save you about 4mm off the thickness of the phone.

I read it here:
http://www.buchmann.ca/Article6-Page1.asp

Maybe I understood it wrong, but basically it states that Li-polymers were developed to avoid the liquid electrolyte and among other reasons, allow flexibility on design. But the problem is that the dry polymer suffers from poor conductivity and high internal resistance and requires a high temperature to operate properly so they added a gelled electrolyte. The technology is generally under development, in fact, the Li-Pol batteries we are using now are actually hybrids at this point and is relatively unstable IMO.
resistance is futile.

Buying cheap rip-off batteries is a gamble, you may get a decent battery, you may screw up your phone, that's all I'm trying to say - you take a risk.
