Actually works well

5 out of 5 stars

Actually works well
I normally am weary of aftermarket batteries, but I love this one. I watched a YouTube video to install it but it was super handy that all the needed tools were provided, including ones that weren't needed but might be useful later. Not only did my machine accept the new battery, but it seems to be performing like an actual factory replacement. It will need a full charge and dischage cycle to work like new. I'm impressed though that after the first charge its charge only fell off slightly and then held charge very well. Calibate your new batteries folks. One good charge and dischage, this battery makes my laptop feel new with no lost battery performance. Very pleased with this.

    Good fit, cycling power to test function.

    This arrived at around 75% power, and replaced the stock battery in my PC 15-eg0000 with no issues. After swapping the battery, it charged to 100% easily, discharged to 8% within a few hours with nothing running on the laptop but the screen brightness at max, but while showing 8% the laptop shut off.
    This fit my HP PC 15-eg0000 laptop perfectly, so if you're replacing a HW03XL battery, this is the right size.
    I'm charging it to 100% again with the power off, since the instructions that come with the battery say to discharge to 10% and repeat 3-4 times.
    The change from 11% to 8% and turning off was abrupt, but so far this is working as expected.
    If following the instructions that come with the battery causes problems, I'll update this review.

    Very strong battery! Came with a 75% charge took 90 mins to get a full charge. Under normal conditions laptop lasted a long time. Second charge from 10% to 100% took no time at all to fully charge. Very happy with this battery. Just buy the battery itself without the tools. They aren't that great!

    Battery won't hold a charge

    Reviewed in the United States on December 7, 2025

    Color: HW03XLVerified Purchase

    Bought this battery in August 2025 and now it doesn't hold a charge. I get maybe 20 minutes on a charge. Tried a different charger but it is still not holding a charge. Followed the instructions for breaking the battery in and it would hold a charge for 3 hours for first month. The second month it started to decline I got a little over two hours per charge. It has steadily declined ever since. I wouldn't recommend purchasing this battery!

    Schwaches Durchhalteleistung. Der Einbau war problemlos, die Angaben zum Ladevorgang und dann arbeiten bis 20 Prozent und wieder voll aufladen wurden eingehalten. Nach 6 Wochen bin ich aber etwas enttäuscht und verunsichert, wie lange der Akku durchhält.
