In fact, with this pack of LR14 batteries (which I use with another product of beautiful design, an LED flashlight MagLite and often "consumed" with very inefficient appliances), there is obviously nothing wrong. If Duracell has that reputation and above all manage to keep it, it is no coincidence: REALLY their batteries last longer than those of the competition. In parallel to this key asset, on the range "More Power", it is always possible to test his stack to see what he has left power. This is a classic Duracell, but now that we're used to it, I miss not find it at some competitors "low-cost".
As for the price, it is cheaper on Amazon than in trade. But I always questions the price fluctuation. The day of my order, this pack was at 7.99, today it is at 8.99. And having already seen on other Duracell products (9V battery), I struggle to understand what explains these changes. It's the only thing where I seem to be useful BE careful before buying, just to save some money. For the rest (so the quality of the product) is eyes closed!
