New iFixit battery stopped charging after two months

I replaced the battery on my Macbook Air 13” carefully following the instructions. It all worked well for almost two months, then the battery not only stopped charging but it’s also NOT even seen by the system:

Battery Information:

• Charge Information:
  •   Fully Charged: No
  •   Charging: No
  •   Full Charge Capacity (mAh): 0
•   Health Information:
  •   Cycle Count: 0

I tried resetting SMC and PRAM. No good. The charger works ok (stuck on amber light, of course), so I can still use the Mac while plugged. Any clues? Bad battery?

Thank you,

Ricardo
