Did you try completely discharging the old batteries before attempting the repairs?
Does or did it work on just the charger with the battery removed? If it didn’t/doesn’t work with the charger alone the charger may be defective. Does the wall power outlet work?
Also are you sure you carefully reconnected everything correctly? I would suggest reviewing the battery replacement instructions:

You may have missed or misunderstood a crucial step. Especially recheck all connections. Are you sure you didn’t damage any of the ribbon cables?

''We all make mistakes or overlook something from time to time. You must have done something incorrectly. Recheck the battery connector again (step 8), especially the metal guard, and the motherboard cable (steps 6 & 7) both ends. These pressure connectors can be tricky to reconnect - "minimal force" being the key words for all but make sure the connection is good. You could also try without re-assembling the case. If that works then it could be exerting pressure somewhere affecting one of the connections. Look for something like a wire or that tape on the bottom right of the right end of motherboard cable. And of course make sure some other connector has not come loose. Myself I use a magnifying glass and excellent lighting when checking a board.''
