You're buying into a battery platform, not the tools.
9Forgot where I read it, but in talking about cordless power tools, it’s not so much about buying the tools themselves but buying into their battery platform, which is only good as long as there’s continued support. Anyway this is for random discussions of cordless power tools and their batteries.

Branching off the discussion with @aetris from here about these tools, in which I tasked myself with trying to see if there are any alternatives to the Neo and Tacklife batteries.
… so, anyone else have a take on this?
I think I found one!

If that holds true, then that’ll suggest that the Tacklife and Neo were supplied by Hangzhou GreatStar Industrial.
To elaborate to @aetris, besides the locking tab profiles, I was also going by their terminal arrangement:
(I don’t have any of these myself, so I can’t verify the interchangeability of the Neo with the Workpro, but at least it appears very plausible.)
Fantastic, @narfcake! I’ll doublecheck but it looks good to me!
Many years ago I bought a bunch of Black and Decker power tools that had nifty removable rechargeable batteries. There was an outlet store near me so I was able to get a good deal. However, the batteries sucked and wouldn’t hold a charge, so I think the technology was abandoned. I don’t seem to have the power tools any longer and I don’t remember if I tossed or returned them.
@heartny If you do run across them and they’re the 18V, then considering an adapter may be worthwhile ONLY IF you already have some B&D or P-C 20V batteries. If you don’t, then it’s not worth it IMHO. You’d be spending more than the tool’s value.
Adapters for older battery platforms to newer ones:
Black & Decker 18V: If you still have tools with the slide-on 18V Ni-Cad batteries, a HPA1820 adapters lets one use more modern Black & Decker or Porter Cable 20V batteries.

Porter Cable 18V: This was their platform before the current “20V Max”. Look for a BSP20PO adapter.

DeWalt 18V “pod” style: DCA1820; the official one has a voltage protection circuit, the generics may not. That is because on the newer 20V DeWalt, the low voltage protection on the tools themselves. Without such, it’s very well possible to run down the battery to below 0%, potentially damaging them to the point of no return.

This is precisely what got me started in the Ryobi One+ realm. Years ago I was buying tools and after a couple of years of use the ni-cads wore out, wouldn’t hold a charge and it was impossible to replace the batteries. I discovered Ryobi around 2000. Their 18 volt batteries have not changed format since then. The technology changed from ni-cads to the lithium batteries currently in use, but every tool that was in my workbox works with the current lithium battery. The actual battery style is exactly the same. This is been a game changer for me and I have acquired multiple tools that use that battery pack. Currently they are evolving their technology on the tool side to be brushless, which is an improvement. That being said the batteries still fit the new brushless as well as the old type motors. I will continue to purchase route as long as they keep making things that fit that same battery back. Anticipate this to be last infrastructure I’ll invest in.
@chienfou This has shaped a lot of my purchasing in favor of Ryobi as well. While I have a couple of very specialized exceptions (like a monster 1/2" impact from DeWalt that has yet to meet a nut it could not remove), the vast majority of my non-18650 rechargeable tools (plus a vacuum and a hot glue gun) are all Ryobi One+.
@werehatrack
There is a great Ryobi to Dewalt battery adapter available that I use on the one DeWalt tool I have since I only have one battery for it.
I’ve also bought into the 40v Ryobi ecosystem since their yard equipment has worked out well for me as well. The 16 inch chainsaw is great. When my current EZ-GO mower dies (old woot purchase)I’ll go with a Ryobi I’m pretty sure.
@chienfou @werehatrack I would warn that of premature battery failures (I.e. not that old, but out of warranty
) the Ryobi ones have failed the most. Now I DO have a large collection of them, mostly because of the frequent deals Home Depot used to have, so statistically maybe not that bad. But I have several destined for the battery recycle bin at Home Depot. Online searches say not much you can do unless you want to hack them, and “I ain’t got time for that”
I have had better luck with DeWalt and Milwaukee which tend to go with more premium tools (though Ryobi has stepped-up its game lately and also has a new generation of high-output batteries — all have been good so far but they’ve only been out about a year)
@pmarin @werehatrack
I’ve only had a couple of Ryobi batteries fail but they’ve all been over 5 years old. My ni-cads bit the dust of course…
@chienfou You mentioned
Could you tell me what it is, s’il vous plaît? I have exactly the same thing - lots of Ryobi batteries and a Milwaukee recip saw with one battery.
@Kyeh
Here is a 'zon sourced adapter.
Some points to consider:
An Amazon search for “Ryobi to Milwaukee battery adapter” should yield multiple results in the $15 to $20 range.
Read the listing closely and look at the pictures to be sure it’s the Milwaukee (M18?) battery format you need.
Check on the return policy to make sure if it doesn’t fit you can return it.
Be aware that most (all?) will not work to charge your Ryobi battery while in the adapter in your Milwaukee charger.
Keep in mind that the extra length might change the balance on the tool a bit and make it awkward to use depending on how the battery will fit. On a reciprocating saw this will probably NOT be a problem,.
On my DeWalt tool I just leave the adapter connected to the tool and use my Ryobi battery as I normally would, charging it in the dedicated Ryobi chargers I have.
Good luck!
I got accidentally roped in the Ryobi system. I needed a brad nailer a few years back and just kept adding on to it since I had two batteries already
I now probably have 40 tools in the collection. I’m happy with it overall, but never really gave it the real consideration on what “system” would best. But I can’t unring that bell now.
@ACraigL I feel like Ryobi’s not bad, it’s what I use. I’m sure the higher end (Milwaukee, etc) are better but I have not fear about support dropping for my Ryobi stuff. I’ve even picked up pretty old (ie they’re blue) Ryobi stuff from the local Re-Store for a steal and they work great with my modern batteries.
Adding a new one here: Hammerhead is Chervon’s attempt to enter the entry-level market with a new brand. It has NOT been that popular, which may have been their reason to subsequently purchase Skil from Bosch, their prior owner. I have a number of Skil tools, but I got these because Woot had a multi-item sale and the drill/impact driver/one-battery combo kit ended up being $22 after discount.
Instead of modifying the Hammerhead tools or the Skil PWRCore 20 batteries, I decided to modify a Skil-to-DeWalt adapter instead. Any which way, proceed at your own risk!
Default fit that will NOT clip in or contact:




Ground down the sides as needed until it clips in:
Good enough:
It’s alive!
@narfcake We can’t all be Torque Test Channel, but a little Dremel work can make many things “compatible”.
