    first of all thanks and big respect to this awesome community. Many times saved my device's life.
    I"l try to make it short . 2 years ago I spilled a beer into my Macbook. I hope that's not a reason of my nowadays problems because immediately after that I've turned my Macbook off turned it upside down and left on warm dry place for 3 (!!!) days. For about year now I have non original charger from with many good reviews. It was working just fine until about 2 weeks ago. Problems with charging, green light when battery was not full or same with orange light. Indicator next to clocks in Mac Os X says charging but sometimes no percentage increase. Here I first noticed that this indicator has two forms too. Whole white or transparent but for me difference was just charging or seems like charging with no percentage increasing and huge percentage drop after disconnecting.

    First my big question: Does Macbook work with battery damaged only on adapter?

    Yesterday my battery dropped this way down to 0%. Last three days I haven't achieved any charge just sometimes it worked as adapter without percentage drop. Only before it went down completely I've noticed that after clicking on my battery status there's a notice of failing battery needed to change.
    I forgot next possible reason of my problems. When charging problems started I've checked MagSafe slot on MacBook and big surprise - full of metal dust and mess. Last year I've used my laptop on roads for work and one time in one factory a lot of metal dust get to my backpack directly to laptop pocket by accident. I've cleaned it immedieately but was in rush so forgot to clean my laptop's magnetic slot. So I've cleaned it when problems started but again badly. To the metal - like you can see on this picture.

    My second big question, could this make some sort of failing contact with inner parts of my Macbook?

    Now I've isolated that part pretty good with tiny bits of ducktape to make it as before but still no charge. Battery must be damaged but what else?

    PS: I don't have an option to try another adapter. Every friend has newer Mac with different cord. There's no near an Apple shop. Original adapter cable wearn off as many others based on reviews and these parts are very expensive for us in Czech Rep. So I'm not much for buying other failing expensive adapter.

    Thank you very much for reading far down here :)))

    Now I left it closed with orange light while I was writing post before and now I'm typing back on my Macbook with 72% and increasing. Only difference from state before is ducktape isolation around pins on Magsafe slot in Macbook.
    Here's my battery status if it went down again

    And now after it charged to 100% light went green as normal. After about an hour I've tried to disconnect and use for a while and suddenly it was on 65%.

    Well, one problem does seem to be the connection. Did you also clean the connector, not only the port? Could be a broken wire inside the adapter cable that connects sometimes. Could also be a loose connection inside the port, which you can't do much about expect replace the port. If you get a solid connection that charges the battery, you may need to avoid moving the computer and cable so it will keep the connection.

    Going from 100% to 65% suddenly suggests other trouble, though, and so does the message you got that the battery is failing. However, your screenshot shows the battery to be healthy. Bad charger connections can accelerate the decline of a battery.

    Sounds like something is shorting out. Corrosion from water damage can take a while to appear and can cause intermittent issue.
