Duracell is among those batteries which lives longer than any other battery. Though they're way expensive to buy but it's worth buying. I used to buy Duracell especially for heavy-duty equipments only but now for everything that is battery operated I prefer Duracell only. I personally recommend this product to be used by everyone. Don't look at the price for it is a quality made product. And, good products are always priced higher! So blindly go for it.
