There is nothing worse than having to replace the battery in the camera like to perpetuate that amazing moment on holidays? Or when you're about to beat my sister's record on Game Boy? So the question is whether it should spend money on expensive HP HSTNN-IB51 battery to replace often.

No, shows the test Fakta test. The difference in price is clearly much greater than the difference in capacity. Of course there is a difference between a couple of the more expensive brands and low-cost alternatives, but it is much smaller than I expected. In general seems to have been an improvement in the longevity of this type of batteries, says the Coggins, test manager at the UK Technology Laboratory Intertek.

The laboratory was commissioned to investigate the life of some of the market's most common alkaline AA batteries. Five major battery manufacturers are represented with two battery models each. On its simplest standard HP 550 battery and a more expensive battery that claims to operate extra good in the products that are more energy-intensive, such as a digital camera. In addition to the five brand batteries tested two cheap alternatives from Clas Ohlson and Ikea.

The batteries were attached to a computer controlled rigging that draws energy from the batteries according to an ad hoc industry standard. The test simulates a typical daily use in both on-and off-mode. To determine if the batteries which promise extra much lives up to the marketing, tested the lifespan of all batteries at two different levels of consumption-"high power consumption" and "very high power consumption". Test at high power consumption equivalent to a motor-driven toy or a portable cd player. Test at very high power consumption equivalent to a more demanding product, a digital camera with the screen turned on, said Mark Coggins.

Stop the man in the best batteries in a powered toy, in slightly more than eight and a half hours while the worst battery (Philips Powerlife) finishing work two hours earlier. None of the low-priced batteries did, however, remove them and Clas Ohlson was only 16 minutes after the best HP HSTNN-IB42 battery .But it was the result of the higher level of consumption that was most surprising, according to Mark Coggins. Nor does this belong to low-priced batteries deteriorate in the test and not Ikea or Clas Ohlson is more than about 25 minutes after testvinnaren.Here, I had expected that the cheap batteries would be much longer after the lead. It was surprising, "says Mark Coggins.
