How many batteries can it take? I'm a little uncertain as to how many batteries this mouse can use. The product description claims that the mouse comes with 2 AA batteries, yet elsewhere, such as in product reviews, the mouse is described as using one AA battery. Which is correct? Can I use 2 AA batteries on this mouse at the same time? I would think that would help with any concerns about battery life.
All I can tell you is that I picked my G700 up at Best Buy in January, and it has one single Sanyo Eneloop AA battery.
I too have read reviews where they said they had 2 batteries, so all I can think is that they must have released two versions of this mouse. Two batteries I would imagine would indeed give longer life, but at the tradeoff of a much heavier weight. My single-battery model is plenty heavy as it is. I don't know if I'd want a second battery at this point.
The mouse can fit only one AA battery, and comes with one Eneloop AA NiMH pre-installed in the box. There is no version of the mouse that I know of that comes with a second (spare) battery or that can receive 2x batteries at the same time.
