The blower and weed trimmer (especially) burn through very expensive batteries (XC8.0) very quickly. It is not a feasible replacement for even a moderate job. My yard is super small and I move quick and have learned to pull the batteries at 50% to keep from ruining them. But I have burnt up at least one $200 battery that will only charge to 75% now. That happened in the first season. Otherwise, performance is good.
I've found Makita to be better for my line of work at least. I love my older Milwaukee tools. My 10" chopsaw from the early 90s is a solid beast, as well as my worm drive. Newer Milwaukee is a crapshoot, I've had three dead batteries from them, none from Makita. Two burnt out super sawzalls, and a miter saw with no idea what true is.
I will say Milwaukee tools have more power to them, but my Makita ones are more reliable. Less frills, less price too.
I am biased as I do more finishing then rough work, so I have an understanding that Milwaukee is better/quicker for that, but I'll stick with Makita for battery tools. I can go two, three days on a single charge with my miter.
My batteries on my blower and trimmer and lawn mower use 56V batteries, up to 12Ah. About 672Wh. The smallest battery I have for it is 280Wh.
Milwaukee might make some decent power tools, but they're still batteries designed for a drill or some other smaller handheld tool used for short stints. Companies focusing on lawn care products have much different battery packs.
It takes me about 6-8 gull charges to complete mowing and blowing. Leaf blowing is by far the more energy intensive. During the fall I have to space out the work in order to charge. Granted my property has a lot of tree cover and therefore always has a lot of leafs and debris.
Needless to say I regret my decision.
One of the problems with the blower is that it has a standard mode that is effectively useless, barely usable for even clippings. You have to run it at “max” charge for it to be remotely effective.
Edit: I have a previous year version of the RY404170-LB backpack blower. It eats batteries like candy.
I pretty much never need to recharge the batteries when working. I haven't needed to do much maintenance to it at all, just sharpening the mowing blade. Even after a few years the batteries still have plenty of charge to mow, trim, edge, and blow both yards. I don't normally have enough battery to do all that and do the hedge trimmer for a while though, I'll normally go inside and cool off for 15-20min and then go back out if I need to handle that. The fast charger can get a pretty good charge in 20 minutes
Is Milwaukee better? I always understood Milwaukee (Red), Dewalt (Yellow), and Makita (Teal) to basically be interchangeable for most products and it just depended on who you ask and which color team they were on.
Separately, I was tired of the stand up vacuums for smaller jobs so got a corded stick vacuum. It's still a bit of a hassle even though I use it frequently to avoid messes getting out of control with the kids and pets. I know that if it was cordless it would get much more proactive usage by others. The design of the corded vac could be improved to make it easier but there is little incentive to do that.
