Experience with a new package of button cells for 3D glasses from Samsung:
The first of these Camelion button cell was still about half the time of a Panasonic brand button cell. The next Camelion button cell already held only about 25%, and the last Camelion button cell from the same package was empty within a few hours.
CONCLUSION: These inexpensive button cell worthwhile only if they are used * immediately *. You need only one or two of these cells and puts the rest in the drawer itself can unload in a relatively short time itself. If you have bad luck and also receives from dealer slightly older cells, this may have already lost a lot of their charge.
SUPPLEMENT March 2013: After many more months of operation with our four 3D glasses I can now recommend the following button cells, which cost a little more, but keep it long and mainly are also easy to store: CR 2025 P-6 BL Panasonic
