Troubleshoot battery problem after spill

I recently experienced a spill with my 2011 Macbook Air.

At first there was nothing, no power at all, but due to the fantastic breakdown guides here I was able to break it down and clean it up to the point that I now have power when it's plugged in, but it doesn't recognize the battery.

Is there any way to determine if the battery is the problem, or if it's the logic board, less buying a replacement battery?

I read another post in which the person bought a replacement battery only to have that fail as well.

Thanks

You can examine the connector and logic board for burned swollen components using a mark one eyeball and magnifier.

I know of no shade tree (DIY) test for this other than putting the battery into a MBA that has no liquid damage (warning; I do no know if using a damage battery can damage the charging circuits on the currently working MBA) to see if it is still functional… and putting a new battery into the damaged machine (same caveat applies about damage on machine killing new battery).

You might see what running the AHT can tell you about the battery/logic board.

If this answer is acceptable please remember to return and mark it.
