Lots of power from this battery lasts for ages. Charges under an hr on a super charger. What more do you need.

Delivers sustained power to your high drain tools such as circular saws and grinders. Will charge on standard charger but takes a long time. Really needs pairing with a rapid charger. Great product.

I have been using Milwaukee M18 tools professionally for many years and their batteries are second to none! I still have some 5Ah batteries which are coming up to over 6 years use and still going strong. I'm confident that these new high output batteries will be just as long lasting.

These are a must have, been using 5 and 4ah for years but the power these put out is unmeasurable. Brilliant and not too heavy
After checking my batteries I realised they were 10 years old so had a complete upgrade to 8ah, they are quite a bit heavier and larger in every way to accommodate the bigger cells, but in my opinion the power upgrade is worth it, it’s like all my tools have been levelled up, most noticeably drilling 20mm holes through joists, these batteries just eat through with self feed bits! I also got some 3ah high output for light weight applications like high ladder work hanging drill on trousers, also great batteries. I’m converted to high output from now on!
I got two of these with plans of getting larger M18 tools. I haven't got said tools yet, but these batteries run my existing tools better than ever. I mainly use them in my higher demand tools like the hoover, circular saw and sds drill.
Good battery much more powerful then standard ones. Run time is longer then 5ah. I'm using it with my M18 vacume and it went to overdrive with this battery.
Soon as this battery went onto my Milwaukee MFCS66 Saw it made a massive difference. The power this kicks out is immense, perfect for a long day of multiple cuts and a great price. A*****
Needed another battery with a little more beef about it to use on my saw this is class gave me the extra Oomph I needed
Great I'm loving the high output batteries fro Milwaukee
