How do you know if a battery is pandorable?

I was thinking of buying the Datel Battery Service Tool, which softmods a battery into a pandora battery and back without the need for a homebrew PSP, and was reading the reviews of said device on Amazon. I read that it will not convert all batterys and there was a serial number - PSP-S110 - that apparently can't be made into a Pandora battery. I was wondering, can anyone confirm if this is true, because my battery has that serial. Should I just buy a Datel Tool Battery? In which case, will the Phat bersion work in my PSP Slim? Because i will probably want to use it on my friends' Phat PSPs. Also, if people can report working and unworking battery serials, I'll try to make a reference for others.

My old phat's battery is a pandora, it only says: MODEL: PSP-110

I didn't knew about the serial, but maybe you should just buy the datel tool

there are only certain batterys that can be pandored, check out this list http://www.pspmod.com/forums/firmwar...lity-list.html
