This is true of all modern lithium ion consumer hardware, because if you don't get this part right, the battery explodes and burns down your house the first time.
Personally, I think we need a cultural-architectural accommodation - we used to have coal chutes, milkman boxes, ice doors. For well-regulated but large batteries like an EV, a detached garage. For raw cells, a grill sitting on the driveway.
I have only had one "Spicy Pillow" from consumer devices (a phone-charger power bank), but with raw LIPOs in RC hobby gear it was an eventuality.
I was a little annoyed that some of the Milwaukee tools require you to go with the M12 battery (the "bandfile" is what sucked me in) so now I've got 2 battery ecosystems for the tools, but I guess that's not the end of the world.
I almost went with Ryobi when I did my recent refresh. But I've changed to doing way, way more with the tools, I'm basically using them every weekend now. And the Milwaukees are just a joy to use, though you do pay for that. One benefit I didn't realize when I bought the hammer drill: It will detect if it grabs and the tool starts spinning. I was using a mini auger to break up some soil and the Porter Cable I nearly broke my wrist when it grabbed. I got the Milwaukee partly because it had a second handle you could add, but the accelerometer worked even better than that.
And then not as any sort of special deal, just the standard retail bundle, the lawnmower with four batteries included costs $700. So that's $560 of batteries and $140 of lawnmower.
It's funny how lithium ion cell prices have absolutely cratered everywhere else, but the price of tool batteries just keeps going up.
I wish there was somebody making reputable quality compatible tool batteries instead of mystery brand counterfeit trash.
No company actually wants to make it easier for people to buy other tool brands.
With brandless batteries, it's luck-of-the-draw, but overall, as much as I do wish there were some way to know what you're getting, I've had good luck more often than not.
What's also been nice is the rise of adapters. My Bosch blue batteries now fit many places they didn't used to.
Some of these brandless Chinese makes are really solid, high quality products, but you can't easily tell which ones because they're visually indistinguishable from the bad ones.
Seems like the tool batteries might be the new ink cartridges.
Tool batteries as a general rule don't do anything fancy internally, so they are easily substituted. I suspect it's mostly a matter of the main buyers being tradies/workers who use them to make money and thus don't care that much about the expense of the batteries - they probably aren't replaced that often.
Would be nice if there was a 3rd-party seller known to use quality cells though, rather than unknown off brands.
It feels like there is a segment the tool co's are selling toward, that leaves another segment underserved.
Eip if this is something you want to hobby-horse on.
Their batteries, at least in my experience, have also been similarly long-lived and reliable over years. And yeah - like some others have said - I also get all my batteries from 'battery included' tools/deals. I don't think I've ever bought one by itself.
Batteries which are used regularly and spend more time between 20–80 percent full might be less "abused" than batteries which are used infrequently, and stored in a room which sometimes gets hot.
As a homeowner I’ve had Ryobi lithium batteries for over a decade. Other than having added a couple battery packs from deals and a couple batteries from tools, I’ve not had a single one of my batteries fail. All are being stored at the maximum charge. Some don’t last quite as long these days, to be expected with age, but not one has actually failed even from being dropped off ladders onto concrete. I did, however, have a Dewalt at work that died from falling 4 feet to the carpet floor. I’ve only had one Ryobi tool fail in that time, and those circumstances were questionable since someone had borrowed it.
Experiences are localized and subjective.
Where it gets fun are the "buy a battery pack and get a tool free" deals. I had a bunch of text typing this out, but the stickied Reddit post covers it better[1]. You can typically get the tool you want for 40-60% off when/if it goes on sale using the "Home Depot Hack". Most common tools do at least once a year - the esoteric items are more hit or miss.
I rarely pick up a tool now at full price. Once I know I want one, I simply add it to a list and note when it goes on sale in one of those combo deals. I've also picked up way more batteries than I ever will need due to other sales as well.
The Milwaukee "buy more save more" event also works well if you need what is going on sale at the time.
Reddit /r/milwaukeetool is a good place to check in from time to time for sales. Slickdeals is great for setting up an alert, but the exceptional deals get sold out quickly once it hits that site. There are also Discord groups out there as well if you go deep down the rabbit hole.
Warning: Once you learn about Packout this becomes somewhat of an addiction for certain personalities.

Sadly one of the best ways to get cheap Milwaukee M18 tools is the “hackable” sales from Home Depot: when 2 SKUs bought together makes them both cheaper, but if you buy them online and have the 2 SKUs sent to different HomeDepo stores, you can cancel one of the SKUs later and the non-cancelled one is deeply discounted. It’s probably a violation of ToS, but customer service reps allow it and support it, so maybe it’s not actually a violation… ? It feels like corporate may eventually ban users who abuse that and cost more money than they are worth.
Milwaukee doesn’t sell via Amazon or eBay and there are notoriously good Chinese clones on those sites.
I did get 3 decent Milwaukee (mostly M18) deals on Woot.com, but you have to jump on those quickly.
There is a great website that does good price history + price comparison between HomeDepo, Lowe’s, and WalMart but I can’t find the link. If anyone has it, please share.
I've done this at least a few dozen times over the past 4-5 years now. I have way more tools than is reasonable for my use-case. No problem so far.
From what I can tell HD doesn't seem to care much - the margin on these things has to be insane, so they are likely still making money on the transaction. Given how the discount is pro-rated across both SKUs you apply the deal to they likely did that on purpose. Who knows what rebates they are getting on the backend from Milwaukee on such promos, but I'd be surprised if there were none.
I imagine if you did this a dozen times in a given month they might ban you for outright suspected return fraud - but for most folks I don't think it's a major concern.
