Does battery affect smc problem

@livfe - Refrain from jumping to conclusions, a battery in its self won’t cause a short or blown circuit. It is no different than any other power source.

A failed component or liquid damage can cascade into a deeper mess!

@danj A faulty battery of course can make problems like board issues.

@livfe - Which come first is the point, power no matter the source only damages when given the pathway to do so. You can’t blame the battery!

Now, if lightning where to hit the charger and travel up the cord it would damage things! But that is still an outside event, just like a liquid spill. A failed component like a tantalum capacitor can create a short on its own and the damaged caused can travel damaging the logic board or other components as the power from what ever source surges is through.

Now the battery in its self could fail, but that’s a physical failure not a power failure that would damage the logic board. The battery can’t send more power than what it can store.

@danj So a faulty battery cannot be the cause of damage to a pathway? Unless a charger suddenly threw an overload of power which went through the battery and done a 'Helene' job on the pathway is that what your saying? This would make sense, true?

@danj There are A load of old questions regarding battery and power issues that you could have a look at sometime, I answered some and got some responses from the question askers even after 2 years or more :)
