    These are all the Acer recommended batteries for the A515-54:

    So it can operate on 11 and 15v batteries?

    The specs I've given you are all the batteries that Acer fits to this laptop and recommends, the voltage are from 11.4V to 15.4V so yes they both work.

    Hi @Maxik

    That Murata model number listed above is not complete should read AP18C4k (31CP5/81/68) Acer part number KT00304012.

    Be very careful with the cheaper LGC batteries as they sell AP18C8K for C4K. The C8K won't work with a515-54AG MOBO/BIOS, I had major issues with LGC better stick with the original Murata AP18C4k with the Acer KT00304012 sticker, more expensive but I have no power issues that I had with the LGC battery.. Our very fundamental BIOS firmware cannot not read SMART and it takes very little to get into trouble trying more powerful batteries

    Hi! After several days dancing around battery i have resurrected it! Seems like controller bug. Discharging in bios then charging several times.. can i set special order of charging during work connected to ac power?

    Is there special software to configure it? I'd like charge to 80% and discharge to 40% but acer care center doesn't allow any settings
