New battery not working

[TonyBaloney]

I am trying to replace the battery on my macbook pro (13 mid 2009) but the new battery is not being recognized. Am I forgetting to do something? Making sure I didn't fry something in the process, I put my old battery back in and it still works and charges. Any ideas? thanks

New batteries have no charge so let it sit while it charges its self.
Try again in couple of hours.

Right now it says "no batteries available" and I have a green indicator on my charger. You're saying leaving it charging for awhile may change this? Does the computer need to be off for this or can I still safely use it while being plugged in?

Let it shut down and leave it for a while.
I dont know how this will go but this is the first procedure.

It may be a defect but you gotta wait to see

np.
If you cant still get it to charge come back later.

ok I just checked and it does acknowledge that a battery is installed but it is still not charging. I reset the SMC; not sure if that was what made it acknowledge the battery. Any other advice?

Try resetting the PRAM (which probably won't do anything, to everyone that posts and says it won't). Otherwise, looks you got a bad battery, mate. Time to get another new one.

Yep sounds like a bad battery. No fun.
