Good resistance and autonomy

Having tested a lot of batteries of this type, I finally found!
I used before, mainly for a mouse without infra-red thread, a model from Animating in 2850 mAh.
But after just two days, it was charging!
With these, I easily hold 4 to 5 days and intensive use.
More than 10 hours a day and without even turning the mouse overnight.

I also used to an old camera and autonomy is significantly greater than with conventional batteries.
In short, a very good price / quality ratio.
