Replacement torch

.. and he'd threatened to use a knife on someone.

I'm now happy because the penknife in my pocket doesn't lock, and has a < 3 inch blade ;)

On ebay I bought one of these which I bid £0.99 + £4.75 P&P:

3500LM Zoomable CREE XM-LT6 LED Flashlight Torch + Universal Battery Charger SP

and one of these which cost £0.99

I've been pleased with my purchase.

I've bought a few of those torches and batteries, and they do seem pretty good at the price. Not sure how many would even understand the SOS mode if used.

22Wh in an AA sized Li-ion? Doesn't sound right, a typical laptop pack takes 6 sub-C size cells to store 45-50Wh

Seems that it isn't right:

Thanks for the link. For 99p I can't complain to much. A set of NiMh would have cost more and would not have held as much energy.

You're right to be suspicious. I've had a pair of 18650 2AH cells, strapped in parallel, that were recovered from a knackered laptop battery pack a couple of years ago and left laying about, which still light up a

55W 12v halogen lamp to a bright red glow (exactly just what you'd expect when fed off 3 1/2 volts instead of the 12 volts they'd normally be powered from) with an open circuit voltage reading of 3.75v.

Considering the 2 years 'shelf life' with no charging - I don't have any suitable LiON charging kit to even attempt to refresh them - and the occasional test *discharge* every so often with that 12v 55W test lamp (probably close to a 4A test load - quartz halogen tungsten filament have a very flat voltage current plot due to the very high positive temperature coefficient resistance of tungsten), I'm extremely impressed by their low self discharge characteristic.

Looking around to find examples of higher capacity 18650 cells, the highest I've seen are 2.6AH then, on youtube, a test of the Olight 3.4AH protected Panasonic 18650 cell and, rather tellingly in this case, a video by a bit of a klutz on fake 6.8AH UltraFire 18650s here:

where our 'klutz' mentions that the highest genuine capacity limit for

18560s is 3.6AH (actually 3600mAH - same thing, just stupid units once you go over 1000mAH values). In this case, some extra 800mAH's worth of fakery.

Here's an Ebay Ultrafire 6000mAh 18650 Battery Review

The only thing to be said for these fakes is that, if you're lucky, you just about get your 99p's worth (as opposed to the hoped for 2 to 3 times capacity of a ten dollar branded cell. It's the same old story, the seller relies on the gullibility of the "Mark" in order to sell their wares by using false advertising.

I have no sympathy for anyone caught out by this scam since, by definition, the mark has access to the youtube videos and other internet sources on such fakery otherwise they couldn't have bought the goods from an eBay trader in the first place.
