The promise of this battery is an ultra long life. One thing is certain, its "use by date" is very long (10 years!), But on its "lifetime use" they unfortunately give precise figures for a comparison between the various types of Duracell batteries, or even between different brands of batteries (for example, or could have, "103H guarantee period continuously during the test Machinchose").
When is a basis for comparison ?? Or why not make comparative advertising as this is allowed?
Because right now, NOTHING proves that the additional cost of buying in these batteries is justified
And for my part, as I have to give my opinion on these batteries in less than 30 days it difficult to go mest after the life of these batteries
To justify the high price, Duracell has made efforts, however, with:
- A handy packaging
- A test détat clever system of the battery load. You should know that for an individual it is difficult to know what the state of charge of the batteries (even with a multimeter, you can simply check which offers slightly higher voltage to 1.5V, 1.5V like all in a state of walk). Duracell offers a proprietary system ("Powercheck") of load test: each cell can be pressed between his fingers, and colored areas whiten according to the level of charge! This system is fast much friendlier than the proposed system on their 9V batteries, much slower and less convenient.
With these batteries, it is actually in the high end, but jenlève a star to my rating because jaurais liked a precise figure of the sustainability of these batteries under real conditions, to buy (or not) with full knowledge of cause. The consumer has the right to know exactly what he is buying.
