Battery LI-ION for Sony Cybershot NP-BN1 NP-BN 1 DSC-W310 W320 W350 W380 TX5 TX7 TX9 WX5 T99 - Latest Update 09/2010 (Electronics)
The battery is easily compatible, unfortunately not visually appealing and looks cheap goods from. But so far it is working correctly. For durability I can not comment.
