I have replaced the battery 3 times

MacBook Pro 17" A1297 mid 2009

None of the 3 new batteries I have bought now work in my system. Do i need to reset something or anything on the logic board. And if so how?

Thanks for any help

Hi Dan, The MagSafe started out green then amber with the battery charge icon showing,charging 0% then switched back to green with an x in the icon. the third stayed green with an x in the icon .I tried reseting the SMC no go.I checked the updates, the computer said it was up to date.
