Swapped out my battery It will not charge. Tried a different charger with the same result. Reset PRAM & SMC, same result. Laptop runs fine on AC power. When first plugged in the power connector shows a green light and I get one LED flash on one of the LED’s that indicate charge level and then that LED is off. Any suggestions? Thanks The charger stays green

I have this same problem with my early ‘09 MacBook Pro 17" and new battery. Although it ran on the AC adapter fine, my 2+ year old battery was not charging, and the magsafe charge indicator never showed amber before, during or after boot up. After replacing the battery the problem persisted, even after resetting SMC and PRAM multiple times. The new battery has gradually gone from showing 100% to 0% charge., and the macOS status shows “battery is not charging”. Do you thing the after market battery is the issue?
