Thanks Niko. I ordered two for my LS300W. For the first 6 months the battery seemed fine. Last 2 months it takes much longer to recharge after starting and is too weak to power more than 20-30 seconds of menu work. I don't dare format the memory or reset the unit. It could abort part way through. I am going to see if there is room to mount both batteries inside this case. Probably demote this camera to the rear window use, and buy a newer camera for the front. Panorama II or the GuardTrak GT2S.
