Sometimes, if both the battery and MagSafe adapter are tested good or
known to be new, a third item may be the cause of the problem... the
MagSafe Board aka the DC-in Board. This can become partially defective
so as to allow power to some aspect of the computer and not the other.
Depending on the specific build model MacBook (older 2006 to 2010)
the part and access may vary; you could check into the correct repair
guide from ifixit.com to see what kind level of effort may be involved.
There often is a different construct for accessing this across the years.

You could get a replacement battery from vendors such as Macsales.com
or other that match the correct specification in your model. Also the power
adapter can be higher output than original, but not lower. Newer usually is
backward compatible to the older Magsafe. Depending on specific version.
Also note in the Apple support article covering Troubleshooting MagSafe in
section about inspecting all those tiny pins in the connector to see if they
are dirty, burned looking, or otherwise not connecting power. The ones in
the computer may be dirty, which may affect power to battery, & so on.
Good luck & happy computing!
