honestly, i would have to see the circuit board to tell you, I dont have a complete list of batteries with numbers to compare to. I want to build a list but there are just so dang many types of batteries with different numbers it would be a lengthy project. Is it an official Sony Battery? what i will do is type in that number and what not and search for it, maybe someone out there has posted a pic of the circuit board so you dont have to open it up, just in case its not compatible.

*i am getting close, i am finding the circuit boards for the s110 1200mAH just trying to find one that specifies the model number. Well i found several but none with a model number just s110. I dont own a slim, so i havent tried the s110, but I would have to say if it has the chip labeled "IC04" it will work you just have to figure out which pin is the #5 pin. I also heard somewhere you can cut the board itself breaking the pcb copper line to pin #5, but they guy never got back to me to tell me if it worked or not.
