Very good product but at exorbitant prices ...

Should we still submit Duracell? After years of presence on the market of batteries and products unanimously recognized by all consumers to be reliable and above all with a life expectancy significantly higher than the competition (the Rabbit thank you!), The American brand has clearly become synonymous high quality.

In fact, with this 9V battery "UltraPower" there is nothing wrong in qualitative terms. After three weeks of use in a smoke detector, of course, the battery is operating with little more to check the remaining energy (and avoid inadvertent cry of alarm detector once the pile end of life experience!). Energy which is (I sink again a nice open door) always at its maximum after a short time of use.

If the product escapes the five stars is mainly because of its price. On the day of purchase, the battery cost 3.69. On the day of this comment is 10.08 ... and the pack of two 9V batteries (Duracell still in course) is 10.31 ... The price fluctuation is very curious and gives a strange sensation (even a little painful ...). Especially as the rechargeable 9V battery (yes, you can also think about the planet and reduce this type of waste) always with the trademark pink Bunny is ... 7.19! Find the error ...

In short, the product is really good and you can buy at Duracell invariably eyes closed. But at what price? That's THE question!
