What to do with 2nd battery?

[UltraManiac]

I just got a Asus laptop and I got a second battery for free.

I am only using one right now.

What should I do with the second one? I will not be using it anytime soon.

Should I charge it and store it away? or should I just store it away uncharged?

or is it better to use both batteries. like use one for a month and the other and so on and so forth?

Thanks

Or you can sell it on eBay. I would also suggest you try classified section but I think you need more posts (2 starts or more rating) to access that section.

Use both, if you don't use one it will degrade over time.
