Until then, I had Energizer ...
In the mouse, there is only one battery, but it is very greedy; with Energizer, I had to give it in charge every other day, and before, with the original one every three days. For those of the joystick, if I used little, it was every month and, in the case of intensive use of a set (without vibration) after six hours.
With these Duracell duralock, "for the same use"
The mouse takes seven days charge in eco mode and eight days in intensive!
The joystick, noon intensive (without vibration). And after fifteen days without having used it - I checked the batteries with a tester - they have not moved; I therefore conclude that this rate, standby time, these batteries necessarily hold promise to keep the charge for one year, at least 80%!
So these are excellent rechargeable batteries; especially for devices that remain long standby in between uses, such as, for example (to be tested), a Wiimote from Nintendo.
In conclusion, compared to other brands, for the price, efficiency, quality and longevity, there is not a moment's hesitation, these batteries are largely the difference. So, incidentally, that in addition to the club testers, I bought four best!
