I can't account for what someone else may experience. However, most of my comments are born out actual measuring of batteries, lights and chargers.

On guy here says he can't tell how many terminals his cell phone battery has - but professes knowledge of sophisticated undocumented battery charging techniques. I kind say of hmm,, really?

For anyone, if you want to complain about run time of a battery, then at least get a mulit-meter, learn how to use it and measure you battery after charging and after usage. Simply, looking at indicator lights, whether they are on a charger or a battery is worthless.

If I did not have a meter, I would always let my battery charge over night, or at least six hours. I would always twist the connectors and make completely sure the battery and charger are connected. I would use a stop watch on my wrist watch to count run time of the battery, and know for sure which mode the light was in.

I've got Lithium Ion batteries that show almost no loss after two years - more than 200 hours of operation. But I have been given "bad" batteries to test and know what happens to their terminal voltage at rest and it is easy to spot a bad battery with a meter.

The only actual question anyone could ask is: Do I have a bad battery or a bad charger?
