I've just wanted to give you an advice.
If u have old battery, like my friend's had, u can replace by any other with 3.7V, but try to find enough mAh. You can buy that Shi da manufacture (~ $10 for 1000 mAh)
I've use if from c75, then solder it. U can see near "B+" on photo
P.S.
don't confuse "+" and "-".
s110 works perfectly.
