With Duracell I am life fared well. And since we have our little girl, we have become downright battery to major consumers. Many toys requiring a wide range of batteries that you have to have in stock continuously. Nothing is worse than just a toy, with the Kleine just want to play, has dead batteries. Thanks Duracell we were able to minimize a little changing the batteries.
But Duracell goes even further. They developed a One size One Colour scheme in which the end user can see at a glance, he has resorted to the correct batteries in the correct size.
Especially the AA batteries can be happy confused with the AAA batteries. Now the consumer can remember, he should require AA batteries, it must be the batteries with the yellow font in the upper left corner grip and not to the green.
Conclusion:
Although they are slightly more expensive to buy, so it's worth it. Because they are longer lasting, more reliable and in this pack has the same 8 batteries at once. That should be enough for a while, since usually only two are needed at the same time.
