I think there is something wrong with the battery. I -believe- it is a beefed up version of greenworks. IE the same motor and battery but better/more rugged other parts. Honestly the greenworks isn’t super well built. There is only a slight difference in the physical shape of the battery packs.
I have the 18" 80v greeworks with a 2ah battery it would probably do like 5 cuts. I did replace the bar and chain with the oregon, and it was MUCH improved, and quieter.
My battery will overheat, and the saw will shut off like you are saying if you try to push it too hard. If you rest it a bit, then it goes again, but I changed how I handle cutting. I do a couple of big cuts, then go do some limbs so I can be moving limbs while it is charging, but it also lets the battery cool down a bit so it lasts longer.
Greenworks makes a -commercial- line which is a step up from the pro line which is 82v. Those batteries charge in 30 minutes, and have the faster chainspeed. I think you have to buy them through a dealer and the dealer is supposed to make sure you know how to handle the saw before they sell it to you. I think the chainspeed cut off is like 20m/s. Some of their commercial ones hit 13k rpms.
I like the electric because it is quiet, it doesn’t vibrate and I don’t smell like 2 cycle oil. It is also a bit safer because it is off when you set it on the ground, and the muffler can’t catch anything on fire. And I don’t have to fight with it to get it started.
I went back to the place I bought the chainsaw and told them what is happening. They gave me another battery to try. That one did the same thing. I even let it cool down overnight and tried again while it still had one bar, but it did the same thing. I’m starting to think it’s the chainsaw. At least Dewalt has a 90 day money back guarantee. The battery though is a 20v/60v, meaning it fits there 20v tools as well. At 20v the battery has 9ah and at 60v it only has 3ah. Greenworks does have larger batteries. Those commercial grade chainsaws definitely are a higher end option, but I don’t think I could justify buying one.
Bronlin, Sean,
I found a kit at the Greenworks commercial website for an 18" chainsaw, battery and rapid charger on “sale” for around $535 US. There is a dealer about 30 miles from me. If I really needed a chainsaw, that might be the one. Kinda pricey for only occasional use.
We are still pleased with the Atlas 80v from Harbor Freight. Ben uses it every day. He trims back brush around apple trees. If you have ever done that you know it can be hard on the drive teeth of the chain. The brush will throw the chain off and it will ding up the chain. We found two new chains for $26.
Unbelievably, the Bauer corded saw is still hanging in there. Powered by the 3000 watt inverter on the golf cart.
You are probably right on par with what I would expect mine to do with 50% more battery. I need a bigger battery. You might check if the Greenworks batteries fit the dewalts, There was something about a rib in either the greenworks or dewalts so they weren’t quite swappable, but they worked if you swapped the guts out. Ebay and such have the knockoff greenworks batteries for sale.
On the bright side, they seem to be what they advertise as far as the equivalents to gas saws. But the price is why I have the ‘pro’ line instead of the commercial line. Apparently aliexpress has about the same deal as I got, 230 for the 18" with a 2ah battery. https://www.aliexpress.us/item/3256806674614259.html?
And if you trust these folks they are saying a 10ah battery is 90 bucks. I don’t know if I do or not, I have gotten batteries not as advertised from aliexpress before. but those were AA’s. https://www.aliexpress.us/item/3256805863104287.html?
You should check to see if there is an oregon replacement blade and chain. It made a world a difference on my greenworks. It is smoother,quieter, cuts faster and doesn’t bounce as much in brush. It isn’t the consumer safety, low-kickback chain either. Part of it might be the sharpening angle, but the chain is about 100% higher quality.
I’ve been contacting the Dewalt company about my chainsaw. They are thinking it should last longer before stopping. So they are offering to replace or refund my money.
So I’ve been looking into the Greenworks chainsaw. But which saw has a better power to battery life ratio. Is it the 60v or 80v version? I’ve kind of ruled out the commercial version unless I can find a good deal around here.
I don’t know if anyone is going to be able to give a definite answer.
If you look at this. Which is lowes search, and it pops up several 80v saws, but they are all capable of different RPMs which at the very least power consumption is different. The longer the bar the more RPMs. I think Cody said there is a new and old version of the 60v. They are cheaply made, I don’t really trust throwing it around, dropping it out of a tree or even getting it wet.
Honestly, I just planned on buying an aftermarket battery or two.
I know I am repeating. The bar and chain replacement did lower battery consumption.
Sean and Bronlin,
I have the Greenworks 80 volt 16 inch saw with a 2.5 AH battery. It charges in 30 min. I’m very pleased with it, but I really don’t have any experience with “real” chain saws–meaning gasoline powered. I got mine from Amazon I think for about $250–maybe a bit more.
I’d say if you’re getting an all new setup, go for the 80v. I did buy both a new Gen 60v and an older Gen 80v. I gave the 80v 18" to my dad and he really likes it.
I kept the 60v because my mother owns a lot of other 60v tools so I have beaucoup batteries. My other reason for keeping the 60v was it had a longer bar and I wasn’t interested in trying to find out which aftermarket bar fit the 80v.
I should note that 90% of what my 60v saw does is buck down logs and branches.
I did not realize the counterfeit’s were being marketed so closely labeled confusing.
Watch the whole video to see a bit which tools usages you’d really want to keep corded powered.
Watch to 19:00 minutes to see the burn down shorted not-safe cell batteries.
S.U.
There used to be more mistakes, in packaging and grammar. The counterfeits actually performed pretty well tbh.
Fake USB flash drives and sd cards got so bad, I won’t order those online.
I actually wonder what happens if you put the right batteries in them, if they perform as well, and dont have the automatic disable after self-discharge like you ran into with the genuine ones.
More surprising was the short test and the fake ones had a blowable fuse, and the genuine didn’t, and relied on the batteries themselves to short. Samsung batteries have a blowable fuse built in to protect against internal shorts that cause fires similar to the one at 19:00.
Brian and i have a lot of Makita tools chainsaws , grease guns , drills and impacts ect , over here we are lot lucky to have the great prices that guy mentioned for genuine batteries , here a 6amp Makita is around $180 AU do a conversion and works out at around $120 for a single battery , we have been buying the rip off 9ah batteries now for 5 years with pretty good results as long as you don’t take them down to where they cut out , they seem to last a good long time , we have had 3 that once run down over and over have gone into fault mode , so now we only use down too 1 bar at $99 for two 9ah were ok with that .
Dave
Google around. There MIGHT be a way to bring them out of fault mode. IIRC you charge the batteries with a pwm charging supply -slowly- without the control board until they are above what the minimum voltage is supposed to be.
When I was looking at the teardown of the greenworks knockoffs besides the battery quality, the biggest difference was they didn’t solder all the temperature and fault detection wires to the board, which is like 2x as much work, but the boards looked close to identical and the spots were on the board for the extra wiring.
Missing ground wires and such were the difference in the soldering iron I got as well.
I had an cheap Skil (19€) that hold up 14 years before the magic smoke leaked out, now they don’t make that model.
hi Göran
old Skil angle grinders had Bosch internals, they were good tools.
i had both Bosch and Skil, scavenged parts from one to fix other.
but not anymore.
newer Skils both 230mm and 125mm were typical chinesium crap.
now i have migrated to Makita, they are pretty cheap, considering their quality.
one thing i love in Makita 125mm grinder is the size of the reductor - it is really small.
that’s good for reaching difficult places.
first thing to fail in Makita is the rotor(armature), but replacement costs around 25 euros - not so bad.
I picked up the 8ah battery for my saw. It is a long walk back to where I am currently cutting. The small one is good for brush but it dies too fast for an actual tree. I wanted to order it before US stock ran out and tariffs kicked in on the new stock. (which I am unclear whether it affects small dollar items or not. Before they didn’t tariff -everything- just over a certain dollar amount.)
You might check if the Greenworks batteries fit the dewalts, There was something about a rib in either the greenworks or dewalts so they weren’t quite swappable, but they worked if you swapped the guts out. Ebay and such have the knockoff greenworks batteries for sale.
