    No. The dealer does not respond and has an invalid postal addr in Germany
     I claimed and got back the 50 euro from Visa. I will buy another one.

    I bought another one and installed it on the weekend. Remarks:
    1. When I installed the new battery, it was empty, no LED turned on. The Acer C720 did not start without attaching power supply.
    2. The battery charged to 100% in around three hours while using the laptop
    3. After this I removed the power and let it drain under usage. It went off after 6 hours.
    4. The original (three years old) battery was of type AP13J3K, the now removed is also AP13J3K, the now installed is AP13J4K, all claim being compatible with C720, C720P, ... I don't know what the difference is between AP13J4K and AP13J3K.

    The battery partbumber may vary, as long as it is compatible with your notebook. However, the battery voltage should be identical to the original battery!

    The original old one has 11.25V output, all others have 11.41V. Any concern or is in the limits of tolerance?

    Accepted Answer
    A slight variation in voltage is acceptable. Even the battery you have installed is compatible with your notebook, see:

    I have here a chart picture of the battery discharging (the gap near second 18000 is due to not have written down data):

    My Acer C720 does not run Windows, lucky I am. Didn't I said this somewhere in this thread? I have no Windows in all in my house. Only Linux and FreeBSD, even on the four smartphones in my family Ubuntu is installed.

    Some users report that the c720 battery on linux, lasts about six hours! Have you already disabled bluetooth and other devices to check if the battery lasts longer?
