Havent had the battery long but it holds its charge very well. Very pleased with it. One small drawback is its hard to remove from the Milwaukee charger I have & the Milwaukee tyre inflator I use it for.

This was a redemption 12v 6.0 amp Battery.Failed after 2 months with very little use.I also have a 18v 12.0 amp redemption battery.It also failed after a few months usage,I have over 20 other milwaukee batterys that are all fine! Some are 8 years ols and used every day.So I must conclude that Milwaukee hands out batterys with known problems as free redempltions.

I redeemed the battery after the purchase of the 12v reciprocating saw. The battery is a godsend as I can now use the saw nonstop without worrying about stopping to charge the main battery

Great battery however the 6.OAh batteries don't seem to like my multi battery fast charger .All my smaller batteries have no problems charging accept the 6.0Ah when they get around the 6 months old wont charge on all my milwaukee chargers . They work fine on a single battery charger but not the multi.Also the clips that hold the battery to the tool are a weak point. However that being said i use these 5 days a week and im very happy with the product.The 6.0Ah is a much better battery for sanding and drilling with its extra run time.
Got this as part of redemption and did form part of my decision when purchasing. There is a notable difference in power compared with a 2.0 or 3.0 battery. I mostly use it in my M12 Blower and Combi drill where it excels. Great product and I do recommend
Only lasted a year which isn't up to the normal Milwaukee standard, considering that some of my batteries are nearly ten years old and although severely down on power are still charging. Thankfully the warranty was a simple and quick process.
Goes forever! But not bulky! Received as a redeemed item and made the purchase more worth while!
Underpowered, Needs to be an M18 and 8" then would buy it and it would suit my M18 batteries and charger too.
got one in a redemption have upgraded 4 of my small batteries to these last heaps longer
I am an electrician and use the impact driver over 2h every day. The M12 6.0Ah battery is redeem from M12 impact driver kit. It is lightweight while ensuring long-lasting battery life. It is very easy to use and greatly improves my work efficiency.
