ACER 575G-54YE Real Battery Name

My third-party battery became wonky since it's been giving false info to Windows.

I think my laptop's battery should be an A8K and not an A5K. I ordered from a shop that offered the A8K but it is just at this moment that I realized that the shop sent me an A5K. 

Indeed, the A5K was still compatible as I have used it for about a year, but does it not have side effects? I can't even run my laptop on AC power alone now, is it because of me using A5K instead of the A8K battery?

Someone please clarify me on this.

    Your problem is one of two.

    (1) The power converter circuit in the laptop is Bad. This is the circuit that converts the 19-volt output to a lower voltage needed to run the laptop computer (ie laptop battery is only 10.8 Volts (uses slightly higher voltage when charging.) 

    (2) Your "brick" is bad. In your case, the power pack is showing the correct voltage with No load (or very low current). However, when you apply a load to it the output voltage drops all the way down to 9 V. This indicates that either the Power Pak is failing (can not supply rated current at rated voltage), or the Input current is too high (above-stated specs - ie Mine indicates 19 V at 4 Amps). If the input circuit in the laptop has failed in a manner that when the power pack is plugged in and the power button is pressed the current exceeds the power pack rating, the voltage is reduced and the system powers off - Then the current is reduced and the power pack voltage goes back up to normal.

    You can first try replacing the power pack - that is probably the cheapest route. You might be able to go a store and try one with the understanding that if it fixes your problem you will buy it. It is always good to use a battery recommended by Acer for this model. 

    Hope for the best!

    Do you see any indicator lights when you plug in the charger?
    It’s possible your charger might be the culprit. Remove the battery and If you have a working spare laying around the home, give it a try to see if it charges. You can also borrow one from your work colleague if you don’t have any. If you don’t have access to another charger, try yours on another laptop to see if it charges the device. Read the brick and make sure it has the same polarity and voltage as the adapter for your laptop.

    The indicator lights up orange for a few seconds. After that, both blue and orange indicators light up, as if it's saying that it's full and charging at the same time...

    I've already tested the charger before and it's outputting 19V which is what it should be outputting so the charger has no problem.

    I am able to use the laptop with the battery on but by disabling the ACPI battery controller on the device manager so that Windows doesn't know that my battery exists; just to complete the circuit.

    I just ordered the A5K battery though, does it matter if I'm going to use that instead of an A8K which was the original? I've heard from another post here the difference between the two, will it affect my laptop in the long run or will the effect very minimal?

    Thank you so so much for this insight! This was the answer/input I was searching for from my recent past post. I have already bought a battery though but I'll try checking if the brick really is the problem. It might take me a few days to see but I'll do my best to send the results here.
