Yes it will.work. that is the great thing about the M18 line. It just won't last as long as a 9 or 12 ampere hour battery

A long time. Theres no way to say specifically because it all depends on your particular use of the tool.

I lost my HD 9.0 battery is this a good choice of battery or should i go for 12.0 thanks

Answer

The high output XC 8.0 AH battery would indeed suffice in getting the job done. You could also go with the 12.0 AH battery, but keep in mind that will add some extra weight. 8.0 weighs about 2.25 lbs and the 12.0 weighs about 3.35lbs

The battery will keep the fan from touching whatever surface you set it on as long as it's flat it's pretty stable

Cannot say enough about great this product is. Milwaukee not only stands by their product but they also believe in it. Ive got a small army of Milwaukee Tools, both 18v and regular hand tools from drywall saws to tape measures. I can say that they are worth the extra money. These batteries last forever, Ive got 3 now because how awesome they are. They cost a lot, sure but I get literally twice if not three time the life. They may weigh a pound extra but Id rather pick up the pound and get 4 more hours.

Can't go wrong with the M18 system. This XC8.0 HO works great for high demand tools at 2.4lbs weight. I'll tell you right away that I'm a huge fan of the M18 system. I have been very happy with the system for a variety of tools I have. This is my first very large battery, and high output type. I plan to use it with future high demand tools (maybe a leaf blower), but for now it serves well for my existing tools, although it is a bit heavier. My go-to battery is the XC5.0, which is light enough and has enough juice for drivers, drills and hand saws. The XC8.0 fits them just fine, but adds a bit of weight. The attached photo shows the difference in size between a CP2.0, XC5.0 and this XC8.0 if you want a reference. Here are also some measured weights of the batteries: - XC8.0: 2.4 lb (this product) - XC5.0: 1.6 lb - CP2.0: 1.0 lb I was using the XC8.0 on my little hand vac and after 20 minutes, it didn't lose an LED of charge, although it did accept more charge. Compare that to the CP2.0 which is almost exhausted. The trade off is simple: weight. This fits the bill for larger stationary tools, two hand tools or power hungry tools like a blower. In my case, it is my back up for now. If I lose power on any other battery, this will fill in while the other recharges. Speaking of recharging, I am using the standard charger. Works fine, but takes quite a few hours for a full charge. Not a problem if you have backup. Mad in Korea and China

This review is for the M18 8.0 a/h battery, model # 48-11-1880. The 1880 is one of Milwaukee's new "High Output" series of lithium batteries. Compared to the standard XC series they're supposed to give 50% more power and run cooler. There's a 'fuel gauge' that shows the amount of charge (see photo below). The battery came with a minimal charge, so plan on charging it before use. No charger is included in this package, just a single battery. One of the hallmarks of the M18 battery line is that there's no performance degradation as the battery runs low on power - it simple reaches the end of its charge and shuts off. Checking the fuel gauge occasionally can keep you apprised of the amount of work time left before a battery swap will be required. When the last light lit is flashing, you're down to less than 10% remaining power. I have an M18 6.0 a/h "High Output" battery as well as this new model 1880. In a side by side weight comparison the 6.0 a/h unit is 2 pounds, 6.5 ounces while the new 8.0 a/h unit comes in at 2 pounds, 6.4 ounces (as measured on my wife's kitchen food scale; YMMV). More power packed into the same sized package. (See the photo below). I'm a homeowner / DIY'er, not a professional, so I can't give a detailed account of how the new 8.0 a/h battery would work in a full day of drilling holes through rafters or some such. It’s difficult to review batteries without performing a full set of benchmark tests, under precise conditions – which, as a DIY’er, I’m not set up to do. I can say that on an M18 angle grinder (model 2980-20) it performs wonderfully. Milwaukee’s new line of ‘high output’ batteries really is a step forward in battery design, I think, rather than just an advertising claim. There’s a 3-year warranty on the battery and, of course, Home Depot offers a 90-day return policy. HTH Regards, Jim
