Will these work with any M18 tools? I bought an M18 drill about 10 years ago. And I recently bought the LED tripod light.

EDIT: Sorry, I think I found the answer in the description. -Versatility: Powers all 200-plus M18 cordless solutions -Compatible with all M18 tools
My 10 yr old drill batteries do not fit my impact. Maybe they don't want me using a 1.5 or 2.0 on a high power draw tool? My 4.0 and 5.0 fit impact and drill and grinder if that helps

Dammn bad timing for me.. been looking for these for a while.. these are good mod for 12v power wheel conversion.. 12ah is great for them.. low weight, smaller package, better than lead acid.

The 12 is just too heavy, I stick with my 9a. I personally don't see the need of the 12a battery. It just weighs too much. 2x 9a or 1x 9a and a few 3a are perfect for most people
12ah we use for the bigger tools that are not being moved around or carried by someone. Miter saw/table saw/tripod lights and such. For hand tools the trusty 5.0 will do for 90% of hand tools we use. We are starting to switch over to the m12 fuel line since they have a ton of power and the tool/batter combo weigh as much as the 5.0battery by itself. There's a use for everything.

Will this give me a 1 month battery life for my iphone?
I'm sure iOS would artificially drain it in the standard 9 hours anyway in the name of "performance".

Yes but some tools have small issues. Older drills may need a different belt clip or need their belt clip removed because the "High Output" batteries are wider. Also, the original M18 wet vac has trouble with them, they slide in but the lid won't close. There is an updated version of the vacuum which I believe solves this (same product code though). The personal fan ends up sitting on the battery if you put a 12AH in it but no real problem.

Yes, but only if you put your tongue across the two terminals first. Wink

Would these be good for the leaf blower?

Ah I see, I still wonder if it is directly related to capacity, maybe just the newer 21700 cells, or the rails/connector between.

In any case "newer" could be misleading, I believe xc8.0 is newer than 12HO, but believe the latter has more "power". I do assume you mean newer design/cells or more accurately/ specifically HO batteries, but this still may not be accurate as I'm told the 3.0HO ( which is also considered a CP battery), which is one of the newest, has only on par power with an XC battery.

Yes the 12HO is another beast though, and I'll assume the 6.0OH also might be more powerful than XC. Still can't help but wonder exactly why.

All this talk makes me want to adapt on one of my fpv drone Lithium Polymer batteries with a 100 + C discharge rating to see if I can't supercharge a power tool. Sure my capacity to weight ratio will go in the toilet, but it sure would be a fun experiment.😂
The 21700 cells heat up less than the 18650 cells, and therefore the power doesn't drop off as much as you get close to running the battery dry. On a 9Ah battery (which has 18650 cells), when you get close to running it empty, you gradually lose power in those last three minutes. With the 12Ah, this effect is less pronounced. And in the winter, the effect is nonexistent with the 12Ah, it basically runs with full power until empty because the ambient temp is able to keep it cool enough to where it doesn't heat up in time to cause power loss. Where as with the 9Ah, the power dropoff is still there.

Umm, yeah. It's the best battery in Milwaukee's lineup for the blower. Other good applications are the Vexilar K-drill ice auger and the Milwaukee M18 Chainsaw.

My wife uses a 4.0 exclusively for charging both her iphone and ipad and gets a full week out if it. The 12.0 lasts over 2 weeks and that's with me getting few quick top off charges out it as well.

If you used it solely for an iphone, I see a month being totally possible.

That being said, be sure to switch the unit off when not in use. I've also see it drain the entire battery in a day if left switched on with nothing connected. I've researched it and that's just the way it is. The USB adapter consumes power, even when not connected, hence the off switch.

I bought into the DeWalt ecosystem because the tools were consistently a few bucks cheaper than Milwaukee, but the last few years it seems like it's always Milwaukee stuff on sale.

Anyone try to get this deal in store? If it rings up with the free 8.0 battery in store I'm curious what the return value is of the 8.0. Could get a nice price on the 12.0 by buying the deal and returning the 8.0.

Just stopped at Home Depot. This deal is available in store but signs weren't posted for it anywhere. Just bring one of each battery to the register and it will ring up with the sale. I wanted one or both of these batteries and wanted to find out the return value of each. Here's the breakdown. You can return either battery for money back. If you want only the 12.0 it will cost you $107.61 plus tax after returning the 8.0. . If you want to keep only the 8.0 battery it will cost you $91.39 plus tax after returning the 12.0. If you're looking for a 12.0 battery this is currently the cheapest way to get one. I wouldn't do the deal for only the 8.0. You can find those for about $75 on eBay.

Just confirmed this does work in store. Not advertised but I had it pulled up on my phone to see if they would match it. It rang up correctly as $200 for both. I feel sorry for the folks only buying the 12 amp for $200 not knowing they could get a free battery! This was morning of Black Friday.
