macbook battery problem

[tim2006]

I have a macbook core2duo 2.0. the battery will not charge the megasafe is always green. I think it is the battery. I am willing to buy a new battery but this would be the 2nd replacement. The macbook suffered with a black x over the battery icon and the battery was replaced free by apple. Now approx 1 year latter this battery problem. Any ideas what the problem is, before I invest $130?

Don't invest in anything by asking us; either borrow a friend's adapter to check the battery [or adapter] or make an appointment to see a Genius who will test it out and tell you what's broken.
