I think I will buy those http://cgi.ebay.ca/2x-BP-5L-Battery-...QQcmdZViewItem Be afraid, very afraid.. (I can almost bet these are a fake (very low voltage battery) with a Nokia battery label pasted on it) If possible try to find a SIDO battery, I've got 2 and they're just abit under the original for battery life, and most times it comes with a battery charging station, you use your original power adapter to power it, and even sometimes comes with a USB charging cord as well.
