I do not think I charged it good enough, sucker ran dead after like 4 hours. I may go into setting and check the lighting and display , maybe I had it set to high to long or some crap. the last one I bought was crap, but cost me $50 and the battery seemed to never die.
If I have to, I will swap the batteries and solder the one in . but chances are the new one has a bigger and better battery just soaks more juice, or some crap.
