Quality is at the appointment. Price not necessarily.

I could talk to no end about the quality of these batteries on Duracell, etc. but it has no interest, the brand is, by far the market leader, has an excellent image is not usurped, and this model has long since found its way into the range ... Nothing more to say about these subjects.

What is more important, for against, is to be careful about the price: the same batteries can vary, Price, from simple to slightly more than double by the merchant (amazon often cheaper postage included, but not still, especially if you buy more than one pack) and especially by performance, by 4, 6, 8, 12, 20, 24 or others ...

So calculate your true needs, compare the unit price (for battery) including port, and you'll have some big surprises!

Note also the convenience of the tester .... but is it reliable?
Personally, I appreciate his presence, of course, but I use my old staff tester: I put the battery in the device and if it works, that's enough. What if I need a VERY sensitive stacks, I put new ones! Franchemetn, between us, do you test the batteries out of the pack? By putting them in the machine? In exiting the device because there is "more batteries?" Hahaha, I bet no ...
