E-shop Reviews
Apparently at Mall.cz they think that they sell only perfect goods, and don't want people to write negative reviews to some of the goods, even though the description contains plain lies. As an example, we take this 9V rechargable battery. In the description, they say:
The rechargable NiMH battery from GP Batteries lasts up to 5 times longer than alkaline batteries [...]
There has to be some serious magic used by either Mall.CZ or GP Batteries, which causes that the battery rated at 8.4 V with 200 mAh capacity lasts five times longer than an ordinary 9V primary alkaline cell. Apparently the later according to Wikipedia has 565 mAh capacity, and thus stores three times more energy than the rechargable batery from GP Batteries.
I have written a comment along these lines to the Mall.CZ system on May 7th, but it is still not published as of now. So beware of any e-shop which doesn't allow negative comments, such as Mall.CZ. It is interesting that some bigger shops like DX are perfectly OK with people writing negative reviews to some of their goods.

It is possible in some use cases to "last 5 times longer". When you put alkaline cells to camera, they can last as low as 50 shots, but NiMh batteries about 250. Alkaline batteries cannot produce high current very quickly - so technically your comment may be considered as not true. And there is "up to", which can also 0,5x. :-) But if this is a 9V battery, which you put to some kitchen scale, it will last about few months and alkaline can be there for years. But it is still "up to 5x", so they are right. :-)
