Need dell battery pinout

[flclisgreat]

someone just gave me 2 dell laptops. a inspiron 5150 and 1100. the 5150 i have a charger for but when i plug it in it doesn't do ANYTHING when i hit the power button. these laptops are known for the power jacks dieing though. so before i rip these apart n rig up a power supply to them id like to charge the battery's a bit to see if iether laptop will even attempt to turn on. so i need a dell laptop battery pinout for either battery type u1223 or 6t473.
