CAT Graphene Battery Testing

[@Tools-Tested]

Ran the same test using the DCD1112 (12amp) dewalt charger. 5AH PS charged in 42 minutes Vs 46 with DCD118 (8amp) charger.

[@IMPACT-NATION]

I love the power from the graphene and charge time but the weight? Damn😂. That’s a hefty battery. Absolutely love the testing methods. There’s always room for error but your margins in that area are quite small if any. Great job brother. All this information is more than helpful to us in the trades or someone that’s looking to get into a new tool platform. I’d say the Graphene style packs would really shine on rotary hammers and circular saws. Very high demand situations. Thanks for the video brother. Looking forward to catching up on your content

[@Tools-Tested]

Yeah its a lot of weight, I agree rotary hammer or a circular was would probably be the best application. Hopefully they continue to grow the line. No problem! Thanks for watching.

[@goldentrucker7921]

I'll stick with my Milwaukee 😂😂 . Cool quick charging though. I've got so many batteries that it's really not a concern.

[@mos8541]

yeah you're right Milwaukee is resting on its laurels, as other companies FLEX etc. LEAP ahead in battery technology, im doing great with my old fukked up NiCad batteries ive got so many, not a concern

[@Oghurrakane]

Just get Dewalt but I heard they got some new stuff in store

[@Chris.Rhodes]

I'm a Milwaukee fan boi. I'll keep my Milwaukee tools nice and safe. 😊

[@johnthumble5154]

​@@mos8541 leap ahead 😂😂😂 that's cute

[@ArthurDentZaphodBeeb]

Cat should be embarrassed to license their name to such junk.

[@Tools-Tested]

Yep whatever it takes to make a buck these days it seems.

[@ccbowers]

Glad to see this. Very curious about the testing. I've been curious to see if this was a legit graphene battery or mostly marketing about using graphene without its actual use in the battery cathode. It seems strange that CAT would be the first company to be successfully make use of that battery technology in power tools.

[@Tools-Tested]

Yep its hard to truly say without cutting it open, but with the fast charging and low temps makes me think its legit. But I agree seems kinda strange CAT is the one releasing this tech, but maybe they are the test. We still don't know what TTI's answer is to the PowerStack and Flexs Stacked Lithium

[@ccbowers]

@@Tools-Tested Seems like Positec is behind CAT power tools, like Worx and Rockwell before them. Legit company, but still surprising. Now, there may be good reasons why other companies like TTI hesitate to be the first here. There are potential downsides/risks. Pouch batteries themselves have a reputation of being less durable and concerns about longevity that we haven't seen yet, because they are still new to real world use in these applications. Combining this with graphene adds more uncertainty

[@mos8541]

well "cat" didn't do anything the Chinese/Taiwanese.. and until they OPEN THEM UP they're NOT graphene... AT ALL.. aren't you curious as to why all the shipping, MSDS, etc. dont mention "graphene"

[@ccbowers]

@@mos8541 Why does the presence or absence of graphene depend on if you open it up? Schrodinger's battery? Makes no sense. They are obviously different if they charge so rapidly- in his testing. Far faster than standard lithium ions. But that seems to be the main advantage. The tools themselves seem, meh.

[@mos8541]

@@ccbowers because PROOF... i wanna see shipping HAZmat label, MSDS, or something tha proves it, jus cuz they charge faster don mean shit.... OPEN THEM UIP I SAID

[@jonathansherwood5841]

Ngl, I was not expecting CAT to come out with a graphene battery like this. Heavy, yes, but that rapid charge turnaround is insane! 🐺🔧

[@Tools-Tested]

Yep would have never thought CAT would be the first. I couldn't believe the charge time, big question will the life of the battery suffer. It's interning they claim 4x the life over lithium.

[@Pinz314]

It's not that insane, a Bosch 8Ah charges 50% (4Ah) in 15 minutes or 80% (6,4Ah) in 26 minutes at the same weight. And it has 60% more energy in it when starting at full.

[@toolscientist]

3:36 you can probably just connect the terminals of battery and tool with wire to activate the battery and then use the load cell

[@Tools-Tested]

Yeah im going to work on that, it just sucks they did that.

[@toolscientist]

@@Tools-Tested are you sure it's got transistors that cut the power? That's unusual as it adds cost and wastes power. I went looking for a teardown but found TTC doing the same load test as you. Can't see any extra wires, but maybe he's hiding something. kzbin.info/www/bejne/aofEmGxmhtN4fMU

[@Alfa75V6]

assembled in China is something very different to engineerd in China ..

[@madcow3417]

Wait wait wait, is there actually a commercially available graphene battery? How? When? What are the specs? Charge and discharge curves? Temperature ratings? Power density? Cycle times? CAT offer no information, and I can't find a cell manufacturer. As curious as I am, graphene doesn't seem to promise anything beyond readily available LTO battery cells so it's probably not worth it for me to buy a CAT battery to disassemble.

[@ccbowers]

I am wondering if this is mostly marketing with graphene material tossed into a pouch cell bettery vs actually utilizing graphene in the battery cathode for actual benefit to the battery performance.

[@Tools-Tested]

Yeah its hard to say without cutting it open. It's defiantly going to be more challenging going forward, considering 18650's 21700's are common cells so plenty of data. As of right now it looks like the pouch power tool cells are proprietary. Yeah the CAT line is small and also looks to be dated, seeing other countries have had the tools for a while now.

[@toolscientist]

Graphene LiPo batteries have been around the RC world for at least 6 years. It's not a graphene based battery, it's a standard LiPo with some graphene to lower the internal resistance. Still debate about whether it's just a marketing gimmick or not.

[@mos8541]

aint no godamn graphene

[@couchpotatomtb7912]

Is there any battery adapter for dewalt/caterpillar?

[@Tools-Tested]

Sadly not yet that I know of, but im sure someone will make one at some point.

[@couchpotatomtb7912]

@Tools-Tested Do you know how far off is a dewalt or milwaukee battery off for actual fit directly on a cat tool?

[@couchpotatomtb7912]

@@Tools-Tested If it's close i can always dremle an adapter abit🙃

[@1schlom]

Graphene ehhh?? Thats interesting.

[@Tools-Tested]

Yeah so they say, the charging is insane.

[@1schlom]

@@Tools-Tested haha yeah, just saying that I've only ever heard that word used for other nefarious reasons.. cool to see the supposed material in practical applications like this.

[@pamirtv3709]

very nice explanation thanks. greetings from Turkey

[@Tools-Tested]

You are welcome!

[@WizzRacing]

I think they used a Graphene Capacitor. Then that charges the lithium batteries back up.. As the Graphene Capacitors hit the market last year.. This would explain the weight... Just so you know. Graphene Capacitors have 5x the energy density of Lithium.. Which makes them very useful for quick charging..With damn near zero heat produced...

[@Tools-Tested]

Makes sense that defiantly could be the case, charging and the lack of heat is insane.

[@mechanought3495]

I'm curious what the difference in power delivery from the DeWalt vs CAT charger is? I'm not finding any specs for the DeWalt fast charger.

[@Tools-Tested]

This dewalt is 8amp, just found out they make a 12amp. Im going to pin a comment once I test the PS on it. The CAT is a 15amp charger.

[@edwardoavila7666]

im looking forward to the development of graphene batteries.

[@Tools-Tested]

Yeah it should be interesting.

[@Hunteratloppshop]

Do you think these could just be DeWalt power stack style cells but with Flex battery circuit board and charger?

[@Tools-Tested]

No the pouches seem to be different sizes, looks like each manufacture is doing their own, when it comes to pouch cells.

[@jeffrellek2792]

Awesome review. I just subscribed!

[@Tools-Tested]

Thanks for the sub!

[@TheSirPotato]

DeWalt has the dcb1112, which is a 12 amp charger, but i haven't seen them in stores

[@Tools-Tested]

Someone also just commented that, somehow I missed that... I have it ordered, will pin in the comments how much faster it is once I get it.

[@travismachado4666]

Cool video you do a good job thank you

[@Tools-Tested]

Thank you, No problem!

[@dmiretti]

Surprising to see this innovation from Cat. Nice video. Thanks for taking the time to do this.

[@Tools-Tested]

Yep being its the first Graphene battery, no problem!

[@BoraHorzaGobuchul]

No graphene in the MSDS sheet for this battery, which is kinda telling

[@delfordchaffin5617]

Yeah, it's big and heavy, but as I understand it, graphene batteries, certainly in the consumer space, are very young. They could still improve dramatically in nearly every way.

[@Tools-Tested]

Yeah this is the only power tool graphene battery that I know of.

[@rinkwolf]

Dcb1112. Is the dewalt 12 Amp charger. You were using the Dcb118 which is a 8 Amp charger.

[@Tools-Tested]

Just retested with the DCD1112, showed a drop in charge time to 42 Minutes for the 46 with DCD118

[@rinkwolf]

@@Tools-Tested was expecting a bigger difference for the jump in power between the 2 chargers. Makes you wonder how the graphene batteries are affected by that rapid charge time.

[@rxonmymind8362]

Waiting for solid state batteries.

[@jeffreycole2816]

the weight kills it. dewalt for the win.

[@Tools-Tested]

Yep the weight and size for a 5ah is huge.

[@camerondrummond8283]

How does that graphene battery handle cold temp?

[@Tools-Tested]

Oddjob thats a good question, It would be interesting to see how this, Dewalt PS and Flex Stack compare in cold temps.

[@thorinbane]

Wow the cat over here is insanely priced in Canada almost 500 for the graphene set.

[@Tools-Tested]

Wow that’s crazy

[@Veau88]

Dewalt has a 12 amp charger… dcb 1112…

[@Tools-Tested]

Sorry somehow I missed that, its on order. Will pin a comment once I test the charge time of the PS on the DCD1112. Thanks

[@mos8541]

open them up

[@GameHEADtime]

When will they put these in lawnmowers!

[@Tools-Tested]

They need to, but looks like the lawnmower uses normal lithium Ion in a 60V battery configuration.

[@avwholesomegamer]

Looking to get away from Dewalt after my first experience with getting warranty service, this looks like what I’m going to probably go with 👀

[@Tools-Tested]

Honestly if you live in the us you might look at the Hercules from HF. That new brushless drill is an animal. So much that I need to upgrade the dyno to handle it. They also have batteries with Samsung 21700 cells now as well. They have come a long way and the warranty exchange process at the store seems better than dealing with the mail it in BS.

[@Veau88]

I agree… i went new HF impacts cuz dewalt impacts are weak… dewalt is better the CAT dont go backwards

[@Mac-vr7yn]

That 5ah is a chunky boy.

[@Tools-Tested]

Yep and very heavy.

[@Bossman211]

Are cat tools cheap

[@Tools-Tested]

Not here in the US, but people in other countries say it’s a lot cheaper vs dewalt or Milwaukee.

[@jonathanrogers9961]

My big question, how many charges will you get before the battery croaks?

[@Tools-Tested]

Yep I would be curious to know the same thing because I believe they claim 4x the life compare to normal batteries.

[@jonathanrogers9961]

@@Tools-Tested 4 times the life would be impressive.

[@Tools-Tested]

@@jonathanrogers9961 👍

[@LaOwlett]

What I want to know, is are these batteries or supercapacitors? Supercapacitors are bigger and heavier for the same amount of power, and they don't have a half life like batteries. They can also charge and discharge rapidly without taking damage = giving you that immediate kick on a circular saw. This rapid dump damages batteries. I suspect inside are graphene supercapacitors and not batteries at all. Why aren't companies combining supercapacitors with battery technology? The supercapacitor can be connected to a controller that can sort of kick it into another gear when the battery strains to start up, or when we push the motor hard quickly. Eg when you start up a circular saw, introduce load, cross over knots, or push the blade too hard - the supercapacitors would do the load dumping to give the motor the rpm boost, and the battery would maintain rpm's... Does that make sense to anyone? I'm not an engineer lol.

[@LaOwlett]

Spoke too soon, you tore them apart! Never seen a graphene pouch. I wonder how it works... 🤔

5:40 might need a ring light. A lot of this teardown is very hard to see

[@Tools-Tested]

sorry the ISO on the camera was wrong, I moved it from the torque wrench test stand and didn't readjust the ISO and focus. I really need to but another camera so I can leave this one in place, but thats $$$.

[@toolscientist]

@@Tools-Tested No worries. Looking forward to the dyno.

[@dogbreath6974]

So that battery is made in China, well I would never have thought that.

[@Tools-Tested]

Yep sadly

[@KM-os4be]

Thanks! It would be interesting to see this compared to say Kobalt 24V system battery price, weight, runtime. Right now you can get the Kobalt ultimate output 24V 8 Amp hour battery for $99 lowes. Seems like CAT battery tools is very late to the party.

[@Tools-Tested]

Plan on testing the Kobalt ultimate but it's probably going to be next month before I have the funds for it. Yep Cat is defiantly really late to the game.

[@three-phase562]

Pretty impressive performance from the graphene battery. With such a short charge time would be interesting to see how hot it gets in comparison to the other manufacturer's batteries and what the charging characteristics are. I wonder if that will shorten the overall life of the graphene battery in comparison?

[@Tools-Tested]

Yeah I would really like to see this compared to the Flex stacked lithium and dewalt 5ah power stack. The dewalt I need to wire a tool up so I can apply the load. Funny part is they claim 4x the life over standard cells, which would be shocking with that charge time.
