Water Damage: Runs on AC, Battery won't charge

My MacBook Pro got a bit wet, and now only runs with the MagSafe plugged in. With it plugged in, everything works as expected, but the battery does not charge, and my power source is listed as the power adapter. I have tried replacing the DC-In board for a chance at an inexpensive fix, but the new board shows the same symptoms. I have a feeling it's related to the battery connector to the logic board, as I'm seeing some very slight corrosion on the contacts of the board and can't seem to remove it after trying to clean it with isopropyl and a toothbrush. Below is the Power System Report and the Apple Store Diagnostic indicated a 'Failure' for the battery. I'm debating on replacing the battery or using a Logic Board Damage repair service if this can't be fixed easily. What should I do? Thanks.

Batteries for these models are very prissy and usually die a lot even from minor liquid damage.

However, the charging circuit could be damaged as well, and may produce the same symptoms.

Just this week I fixed 3 of those. One needed a battery while the second needed board repair and both were not charging; the third needed both :)

But all the wet retina models that I fixed needed a new battery. Whether only or in addition to board repair. The non retina, I'm yet to see one damaged from liquid spill.

First try an SMC reset. If no change, take it to Apple and let them examine it.

If they quote a top case, you need a battery.

If they quote a main board, you need a logic board repair service.

If they quote both, you need both obviously.

Or send it to a reputed repair store that will examine it and quote for you the needed.

Look up my profile, you have a link to a website with repair technicians who can perform this for you, if you'd like a few suggestions.

I would try replacing the battery. Whenever I get a device in that has been water damaged, I usually have to replace the battery because water can short circuit the battery and ruin it.
