Buying used 2g but want to see charge cycles left?

[Dadeleine]

Hi all
Buying a used 2g for the wife (before you ask, she uses it for a phone/camera/contacts only...no data).
I want to see if the one I'm buying has a decent battery...any way to check? Like something similiar to coconutbattery?

I thank you and you.....and you in the corner.
