Who never fell for a pack of 18 to 20 AA alkaline batteries of noname brand in a discount supermarket thinking make a deal and ended up with devices whose battery emptied in just two days? Buy Duracell is a guarantee of quality. The famous advertising with rabbit was right. Compared with other famous brands last longer. I had seen many times like when I played the first Gameboy, when I used walkman "cassette" with my clocks with MP3 players, etc.
The cardboard packaging distributor Format "can of coke" is convenient and prevents the batteries from falling and secures against dust or contact with surfaces that the "unload". Sold by 24 to just over 10 this AA battery pack is a bargain. Buy the eyes closed.
