The more savvy US and European, manufacturers, send staff over there to ensure that this takes place. If you are buying something from a purely, Chinese or Indian manufacturer, then this quality control can be distinctly lacking. IP: 81.129.213.118

I brought a 12,000 lumen hand torch last year for about 25 quid, just for giggles really. Needless to say it was pants, not a patch on the old P7 torches of 6-7 years ago that were labelled as 900 lumens, and even that was an overestimate I think people just print what they like to make it sound good.

We dont know. Recycled laptop batteries will usually have the remains of a solder tag, but some of the manufactured stuff is rubbish. I was tempted to order some. If you ensure that the cell is fully charged, check the voltage on a meter to see how good the charger is. Should be 4.2V. Then connect to a 1 amp drain is easiest, connect through a multimeter for a better picture. I would connect to a XML LED through 3 X 7135 chips, should be 1050 mA, near enough. Unless someone can think of something better. Some of this stuff is better than expected and you wonder why they have to missell it. Maybe the 9800 mAh was a sales ploy knowing everyone would be buying them to test just for a laugh. Orientals are supposed to be inscrutable. -- We are what we are through what we become.

When you think about it as the voltage drops they get dimmer - filament less hot so lower resistance. Be interesting to see what you get at different loads. I assume the rating is at a fairly slow discharge. Regards Andy IP: 78.150.114.235

I can get 1 single or multiple cells in series to try them measuring run time and current draw. Also re-charge time at known current. They are shown as dispatched so let's wait and see what turns up.
