Property me the battery immediately ordered twice because both my 6 years old dual Hocks but then wanted to be frequently recharged. The expansion of the old battery and install the new one as described here have often little fiddly, but manageable without manual fairly quickly, and I'm not now born Feinmechaniker. Cut away any plastic parts I did not need the way, the plug of the battery fits with some force (the tip with the pliers phone was very good!) At once pure. After reassembling the battery still fully charged and lo and behold, the old DualShock does it again (and hopefully for a long time).
Update as of 25.10.2012: Have now been several hours playing with the controller with a new battery and the battery indicator has not changed (still full). The higher performance of the battery thus seems to prove themselves.
