my macbook will run on charge but not on battery alone. The battery works fine on another macbook of the same spec's. my previous battery was faulty and im wondering if it could have caused an issue with my logicboard when it was installed in my macbook.

Original Title: can a faulty battery cause logicboard issues
MacBook Pro 13″, macOS 11.7
There are no pervasive reports here of bad batteries doing damage to the mainboard specifically. So my assessment is that mainboard damage from bad batteries is extremely RARE -- Unless it leaked.
But if the battery was swollen, it can push up on the trackpad, and can cause erratic operation and possibly additional damage to internal components.
These batteries are generally glued in place with industrial-strength glues. The general repair procedures for battery-ONLY repair requires that EVERY component be removed from the chassis while the hazardous solvent is applied to soften the glue.
That means if you did a home or third-party repair, there is more than a trivial risk that something got damaged while removing or re-installing, or did not get replaced properly during the repair.

Apple does not replace batteries (in the field) at all. They swap the battery/trackpad/keyboard/top-plate assembly out as an assembly, and send that module to a factory for refurbishment.

if it works to your satisfaction then carry on. If it is cost effective replace it.
I never heard of a logicboard being damaged unless it is expanding/leaking physically impacting the logicboard, which is a known issue yes—not recommended.
