    This review is about the battery capacity: 5 Ah

    Between the size 5 and size 4, prefer the latter; very close in size but the size 5 is quite a bit heavier.

    This review is about the battery capacity: 12 Ah

    This specific battery has no difference from the other 12ah because this one, from what I see, has a different button that shows the battery indicator and it looks a bit different from the other one. Is there any difference? Please respond if anyone has it

    This review is about the battery capacity: 12 Ah

    I bought it for a Milwaukee FHP or 2915 for those who know the tool I'm referring to, at first we were using simple 5Ah batteries which would heat up and run out very quickly, with this 12Ah the tool has changed, you can tell by the sound and the duration of use, it's obviously not comparable, it's an expensive battery but if you work with more demanding machines it will be very useful.

    This review is about the battery capacity: 5 Ah

    It is on the edge of weight/performance. It doesn't tire you out because it is relatively light and lasts quite a while. However, one is definitely not enough. I have 4 m18 and 3 m12 with two chargers so I never run out. Maybe later I'll get an 8ah for the impact wrench because it's the only one that doesn't last long. The others (grinder, drill, impact wrench) are excellent

    This review is about the battery capacity: 5 Ah

    Much more powerful battery than the 2 Ah, approximately double the power with screwdriver and more.
    Perfect!!
