I’ve recently moved up to the Milwaukee 6.0Ah battery after using much smaller capacity batteries in the past, and the difference is significant. The runtime is vastly improved, which makes a real difference on longer jobs without constantly swapping batteries.
It also feels very solid and well built. The larger base gives the tool much better stability when set down, which is something I hadn’t appreciated until using this. Overall, a noticeable step up in performance and usability compared to the smaller packs I’ve used before.
Great battery. Last a long time and great power on the impact and drills
Great battery at a good price, quick and easy to pick up
Really good deal, two batteries for little more than one from other retailers. Staff very polite and helpful in depot
Milwaukee 6ah battery Milwaukee don't need to say anymore
Excellent value for money on Black Friday deal. Ideal for the soldering iron as makes a stand for it as well. Win win
It’s just a battery not sure what else you can say
Not too heavy and good battery capacity, typical Milwaukee quality
My first 6amp on the m12 range wish I’d spent the extra money in the past for this as it is used in my 12v light and lasts a long time
does what it says on the box and turned up on time
decent battery, it does what it says, it's compact
Good price, plenty of power. Ive been changing this battery between soldering iron and 3/8 ratchet for ground 2 weeks now and only recharged it once. Sgill on 3 lights
Small but mighty, lots of grunt for a small voltage. Used with a drain snake cleaner lasts ages and enough power to get through the 7.5m of pipe.
Good battery, 1st class service from Toolstation as alwaysm
Great service. Good price. Great friendly staff, helpful.
I’ve been using the Milwaukee M12 6Ah battery for a while now, and it’s been a game-changer. The extended runtime is fantastic—I can work much longer without swapping batteries. It charges quickly and holds power well. Perfect for heavy-duty tasks, and the durability is impressive. Definitely worth the investment for any Milwaukee M12 user!
Looks cheap and nasty and did not last very long for amp hour battery
Best price around, great value with quick delivery
Great amount of power and it lasts for a very long time. Very happy with this product I brought two.
Usual Milwaukee quality and good 6Ah size that lasts well.
