Around the house I have several devices including solar cell lights, rechargeable flashlights etc that use 18650 size batteries. Does anyone make a decent 18650 battery? Most of mine came with the rechargeable solar cell light or flashlight but I have purchased some additional batteries online. They are all lousy. I can use the flashlight for only a few minutes two to three days in a row and then it has lost its charge. The same is true of the solar cell lights. Despite the fact that the solar cell light only triggers when activated by motion, unless it is a really sunny day, the battery does not retain enough charge to fully power it.
If there is a good brand, please let me know. I have tried some that were advertised as Samsung but online you have to wonder if that was really true.
Here is a picture of the type of battery I am referring to.
