Review: Amazing build quality and powerful long lasting - If you are operating impact drivers or hand drills a 4.0Amp battery is enough. The 5.0 gives you more time and the extra 1Amp is wasted money. But if you are looking to run circular saws or even a D-grip jigsaw or sawsall then this is a good battery for you. You could go further and get a Milwaukee high demand or even a high output upgraded version of the 5Amp if you are running beefy Milwaukee tools. Still a quality battery and just giving some info for newcomers to Milwaukee.
Review: Perfect. - This battery charges quickly and holds it charge well. Depending on how much work you put the battery through will obviously have an effect on its longevity. I'd only ever buy this battery as it is reliable, robust and perfectly adequate for me! It is expensive, yes, and this is my only complaint. It does the job and will probably last well!

### ⭐⭐⭐⭐⭐ Definitely worth the money
*by C***R on 11 April 2019*

I have 3 x 5 Ah batteries and a 4Ah , for my site radio. They are all genuine Milwaukee and not looky-likey ( which cost about two thirds the price of an original, cannot be guaranteed and in my opinion are not worth £40 + . I have sent one back in the past) These are excellent batteries
