On bottom right of the label, '2-177-077-01' would be old styled, 'CGA-4B101B' would be new styled. Old sytled is the pictures you see in the guides that work. The new style is the Dam psp-110 model that everyone wants the information on how to make it into a pandora batt but noone seems to ever give an answer. There is no ico4 EEPROM on the new ones board. I did find out though that the hack basically shuts down the EEPROM which is the ico4 chip and forces serial number 0xffffffff to be sent. On the new batteries the EEPROM chip is the LO2 8 pin chip. I am going to find a pin-out for this chip and let yall know if breaking the ground on it causes it to go into service mode or not.. (cross fingers) any information about this I would be happy to hear as it would be nice if someone already has done this and knows if its useless or not..
