Trying to get times from your video, I get 12 AH battery = 11 sec. 9 AH = 12 sec 6 AH = 14 sec 4 AH = 18 sec Not surprising, since the larger batteries can put out higher peak current (in addition to lasting longer).
im surprised there was a bid difference between the 4.0 and 6.0, theyre both 10 cell batteries, thought the 6.0 would just have higher amp hours not higher amp output, but clearly the 6.0s are much better cells
No, the "power" is volts x the amps that the battery can deliver. Higher Voltage alone does not necessarily mean a chainsaw is more powerful. Power = Volts x Amps. The Milwaukee M18 batteries are all 18 volts. They are able to meet and beat the power of many 40V chainsaws because they can deliver that 18 volts at much higher amps. In addition to their higher capacity (i.e. longer life), the larger amp-hour batteries are also designed to deliver higher peak amps without overheating as compared to the lower AH batteries. So the saw will be more powerful when running off Milwaukees 12 AH batteries. Not because of the AH rating, but because they also designed those big batteries with a higher max amp rating. It won't necessarily mean all your tools are more powerful when running the 12 AH battery: a tool with a smaller motor may not be able to draw the higher amps, so the 4 or 5AH battery may already be capable of delivering everything that that smaller motor can handle. It's a bit of an over-simplification, but the 4 AH batteries could deliver 1 amp for 4 hours or 2 amps for 2 hours. Amps x hours = 4, right up to the max amperage that the battery can safely handle. (In reality, the batteries suffer a little at high amp draws, so Amps x Hrs may be a bit less than 4 when you are at the upper limit of the amps it can deliver.) 12 AH batteries could have been designed with the same max amp limit if their focus was mainly on delivering longer run times, but Milwaukee chose to make them capable of higher amps, as well as a higher AH rating
I was running this saw for about 2 hours at about a 30-50% duty cycle ru-vid.comUgkxfQm1wmg0ItKDLavxj1nXtQY9HP7EF504 and it did a great job. I used the lever for the built in sharpener to clear chip buildup out more than to actually sharpen the chain. It managed to cut some hardwood stumps much larger than it's size without bothering the neighbors with hours of 2 stroke noise.
I've noticed a lot of people reviewing these battery chainsaws doing exactly what you're doing. That old habit of revving the engine to maintain RPM between cuts is always there even though it's probably not necessary on these battery-powered saws. Its a hard habit to break, no doubt, but it always makes me smile when I hear it because I don't doubt I'd do it too. Thanks for the great video.
It's a hard habit to break. It's also unnecessary on gas saws, unless they are tuned so poorly they will not idle. However, I'd guess about 75% of the people I've seen running gas saws do it.
I just picked one of these little bad boys up yesterday. Have yet to make a cut. But after watching your video, I’m supper excited to fell a tree or two. Thanks for your video.
I own multiple M18 tools. Bought a Fuel 3/8" Imact a few years back,and was so impressed,I haven't stopped buying. Even all my friends are so impressed by the M18 run time and quick charge time,that theyre junking their DeWalt and upgrading to Milwaukee. Didn't know they had a chainsaw and a 12ah battery now. I know what I want for Xmas now. Great video!!!!
great video. back in the 1970s minnesota. I had a 3/4 hp sears electric chain saw with 26 in bar. I cut a lot of wood with it. Yes you needed an extension cord but that was still a lot less fuss than a gas saw as long as you were near power. Electric saws are very handy and this new battery technology saw is worth having.
I'm impressed and sold on buying one. I work in a industrial environment and have several milwaukee cordless products and very satisfied with them. Wouldn't be without them. Great video. Thanks.👍
Im using my Milwaukee cordless sazzall with long wood cutting blade for small tree work but, YES if i had the money would invest in the chainsaw after seeing your demonstration (good-upload)
I meant 18 gauge nailer it was a bit too early released, way too big and bulky for 18g nailer and also leaves impact marks on wood when firing and still nail not necessary set sub-flush. 15g and 16g nailers seems to work better.
I don't know why some people think you have to have the best most powerful product ever made or you're crazy. If you buy a battery saw and it fits your needs, great. It's like people arguing about what car is faster. Who cares? Do you like it? Some of us have a budget, and don't care if it could be slightly better for twice the price. Every battery saw video, some douche has to say that it's not a logging saw, couldn't clear a huge field of big trees. By that logic, nobody should tweak a car because a top fuel dragster will always be faster. Just buy what works.
Hello sir. This is exactly the video I was looking for before buying the chainsaw. I am very happy. I am going to buy this chainsaw tomorrow. You are my best friend today! I already have Milwaukee tools. I will buy the 9 amp batteries. I could give up the gas chainsaw with all the problems that come with it.
I don`t know how I missed all these video....very good tests for Milwaukee ....they should send you a few batteries for this test....good video Gilbert....CHEERS
As a general statement, that is true. However, being one of the heaviest battery saws, this Milwaukee weighs the same, or in most cases more, than a 40 cc gas saw. This saw weighs 14 pounds with battery! Google some 35-40 cc saws and look at the weight. I found one as as light as 7.5 pounds. This is not a light chainsaw. I was shocked when my neighbor's saw was lighter than my 11 pound Makita.
Pull up the tip of the bar and hold it up as you tighten the bar nuts. This take a the slack out of the chain, ans allows the chain to stay tighter longer.
dont you want your chain to be a little loose, I'm pretty sure my dad showed me that you never over tighted a chain it will wear it right out or break your gear/clutch.
brian chaney You want the chain to snap back to the bar, while allowing the chain to still be rotated around the bar without excessive resistance. The chain should never be saging off of a sprocketnose bar. A loose chain will have a tendency to pop off of the bar, whuch is dangerous, and can cause damage to the saw and cutting components. A chain that is a little too loose will also wear the bar down excessively, near the tip and the tail of the bar. This is due to the chain coming off of the bar do the centrifugal force and slamming back on to the bar which will create divots, again near the tail and the nose of the bar. Hard nose bars are different story you have to keep them a bit loose but they are only used in special conditions and are rarely used today.
The older, solid nose bars required just a little slack in the chain to prevent excessive wear. The recommendation used to be that you should have the chain hang loose just enough to fit the edge of a dime in the gap (on a 16" bar). With a sprocket-nose bar, there is not as much friction over the nose, so that bit of slack is not needed. The chain should be just lose enough to move freely by hand when the brake is off, but not loose enough to leave slack when at rest.
Thanks so much for the video. I have been looking at this for a while now and pondering on whether or not to purchase. I was on the farm yesterday using a Stihl gas powered and had all the typical issues. I have thousands of dollars worth of Milwaukee tools and swear by their equipment. This video has solidified my decision to purchase one.
many sellers online in canada have them with a 12ah rapid charger and bonus 9ah batt for 599$ not a bad deal at all if you have other tools to use the batteries with.. kinda wanna get it just to see how my fuel grinder likes the 12ah
Maybe Birch is invasive where he lives. I know there are some invasive species where I am. I wouldn't cut a healthy Birch down where I live unless I was going to build something from the wood.
I want to simplify the mechanics of a battery a bit. think of it as a car. The amp is the capacity of the fuel tank. The Volt is the horse power of the engine. (there is a bit more too it tho)
No the watt hr is the actual capacity . . 12 amp hour at 18 volts has no more amp hrs of work in it than a 4 amp hour at 56 volt ( all things being equal) and their watt hrs ( of stored energy will be similar)
High volts to get capacity means you can use thinner wire and smaller components . Lower volts to get same ( horsepower) means you need beefier wires , motor and components. Milwaukee's route .
I already own some Milwaukee M18 tools, and if I ever need a cordless chainsaw, thanks to you I now know which one it will be ! And for people that have noticed that you've been pressing the trigger between cuts, tell them that it's for cleaning up the chain of accumulating wood chips... ;-)
Is this model 2727-21HD ? And if so, what's the weight (including the 12A battery) ? Did you feel the need to ever use the variable speed on it so far ? Merci !
Great review and demonstration of the saw's capabilities. One thing of note is that you are bouncing back and forth between high output and regular batteries. I've had the non-high output batteries get too hot and turn off.
Don't need to push-release-push-release the trigger. It is just drains the battery. If you are doing continuous work like in this video just hold the trigger. Don't release it between cuts.
I have had my Fuel Impact and Drill set for about that long with 4.0 amp hour batteries here in Alaska. Batteries stay in the truck year around, haven't had any problems yet discharging in either heat or cold, unless in use.
Theorimlig good point. Most people I know make up a gallon of mix and are hard pressed to use it up before fear of it going bad. Batteries seem to last 5+ years,even ryobi's. These seem to be a good option if you already have other tools using the Batteries.
The problem with using smaller 🔋 is not the lack of power but thermal heat cutting out due to the current draw being to high for its capacity. A fully charged 3 or 2 amp-HR battery might get too hot & simply cut out for its peak power usage. Its basic thermal dynamics. Use the 9+
@Mykel Hardin Similarly with the Stihl AK vs AP range . I have both . They have also recently released something themselves essentially ' high output' version . Ap 300 has 227 watt hrs ap300s has 285 watt hrs
@Mykel Hardin So more chances for a fault developing in one of the cells with higher voltage .... ....there being more of them ..more connections . This 80 v max crap is nothing more than marketing BS'
Birch is about the easiest of a hard wood to cut . Give it some REAL wood bro . A 140 msa stilh would've cut that faster . So I'd imagine the 200 battery stilh would've really smoked it . Mb the skinny Stihl chain just works better on birch ( I would've thought the milw would beat it) mb the milw chain didn't have the best edge .
Not quite that easy. The 6 amp packs have 2 sets of cells in parallel (so they can deliver about 25 amps continues) the 9 amp has 3 sets of cells in parallel (so it can deliver roughly 38 amps continues) the 12 amp has 4 sets of cells in parallel ( can deliver around 50 amp continues)
For years I wanted that Makita sooo bad, but I'm not going to buy into another battery platform ever again. I'm sure the Makita has not disappointed you.
im looking to purchase my first chainsaw and seriously might consider getting this instead of a gas powered one. i already own a handfull of milwaukee products and am pleased with all of them
I've noticed a speed/power difference between a 1.5 a.h battery and 4 a.h battery in my impact driver as well, almost as if it unlocks the full potential of the motor so I kind of see how you can use the 12 a.h battery for felling/bucking and the 9 or 6 hour battery to de-limb. I was also hesitant looking into cordless chainsaws but the power and battery life seems more than adequate for small jobs around the camp.
if you had 3 12.0s and 2 rapid chargers so 2 could be charging youd almost be set for preffesional use, in the morning you have 3 batteries to get the heavy stuff done then 2 are charging while your working that will almost keep up with constant use if you have to limb buck and load the tree.. thats probably an 800$+ setup though a 3-400$ gas saw would do the same but this electric with the batteries is alot less hastle and will 9/10 times never need engine repair, ntm some people will really benefit from the lack of noise
i heard they may be releasing a new charging next year for the high output batteries, as they can absorb quite a bit more charge then the rapid charger can provide, that might make 2 12.0s and a charger a viable option for continuous use
Andrew Browner. I can see the cordless chainsaw as a great option for professional use (like an arborist for example) in the future but even the best set up can be prone to dependability issues and fail. Batteries cost a fortune and they last maybe 5-7 years depending how hard they are used and they overheat as well. The technology has evolved greatly in the last 10 years, like useless NiCad batteries to Lithium (I hated the old batteries lol) and going from brushed to brushless motors made a significant difference in both run time and dependability. It will be interesting to see cordless tools progress in the next 10 years. 👍
Olie and the chain saw joke. Olie stops by da hardware store for some supplies. the store man says, Olie you need one of these new chain saws to make your life easier. OK, after a week Olie is back and he is not happy. He tells the store man, I want my money back this thing is so hard to use it almost killed me to cut some fire wood. the store man says. let me check it out and pulls the starter cord. Olie says "Whats that sound?"
NO! the two-bolt attachment is a FAR superior system to the toolless stuff they have on some saws. The 2-bolt bar system is a big selling point for me.
I have the Dewalt version Very nice and good power Not too heavy either Only thing I don't like is that it has a very small oil reservoir ... How much oil does the Milwaukee hold ??
Like the weight, and technology, however if this is a green purchase it is important to note that fossil fuels still produce most of the electricity that will recharge the battery.
I’ve been wanting one of these saws for a month now. I used my old poulan pro 18” saw to cut up a downed limb off a giant maple tree that fell at my aunts cabin. The poulan hadn’t ran in a couple of years and it took about 2 hours of work to get it up and running again. Not to mention the weight. My forearms were sore for a couple of days after from using the saw for 3 hours lol. Being 55 now I can appreciate the convenience of slapping a battery into a tool and pulling the trigger. The only things you have to do with the Milwaukee is adjust your chain, add chain oil and make sure the battery is charged. For me it’s either going to be the Milwaukee or the Husqvarna. My only question is can I put an 18” bar and chain on this saw and run it that way ? Has anyone done that and survived haha
You start out comparing High Output batteries then go to less quality batteries. I could have told you before the test they wouldn’t do as well. That said if you got all high output they would perform about the same.
I have a neighbor at the summer home, ER doc. He won’t start his chain saw without full PPE on, gloves, chaps, jacket, eyewear. He’s patched up too many people with major injuries from chainsaws.
The dewalt is built to fail: m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--yIqluXVleo.html At least the Milwaukee is built better: m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o55Dw0-VEeY.html The greekworks is solid metal as far as the drive train goes. Just following ohms law an 80v 4ah battery and associated tools will have more power and last longer and be less stressed as far as the electronics go assuming they're built/engineered similarly.
Idk about doing jobs with the Milwaukee chainsaw all day long and I wouldn’t pay big bucks for all those 12amp batteries. I’d buy this buy for home but I have an m18 milwaukee saw zaw with a pack of wood blades that cut like a hot knife through butter. Think I’ll pass.....
Good video of the real world use of a battery powered chainsaw Need to refrain from reving saw when not on a cut This just uses up battery power and is hard on the electrics by applying unnecessary power spikes I do the same thing from muscle memory of many years of using Gas powered saws 😢
