New to your channel bro and loving the vids man. Love the local trades getting on youtube. Cheer bro and keep it up.

My skill saw cuts out way more often with my 2ah compared to my 5ah. Haven’t noticed any difference when I used them in my combi drill tho. I think comparing the Watt Hours is a more accurate way of talking about it. 36wh vs 90wh for instance. Great video once again mate.

Higher amp-hour batteries get less stress under load (so you don’t burn out a battery as fast), and can deliver maximum performance longer. That’s it.

Try the same power test with an angle grinder :)) And you will see the difference.

I subscribed after reading a comment by you in in a geographics video and then looking at your channel. Great channel BTW

Awesome! Where I found a big difference was my old impact driver. I used an adapter to remove my Subaru lug nuts which were torqued to 95 Nm. The 3AH didn’t remove them. The 5AH did quite easily. Otherwise as you say not massive difference but that was where it was very clear n

Good video thanks

I accidentally threw a Makita compact batt on either my grinder or metal circ (don’t remember which one) the other day and didn’t notice until I pulled it off. I was befuddled and impressed because I definitely would have noticed the performance lag with the other brands I use.

It's been way too many years since I've cracked my EE books, but I have noticed a difference between the new batteries and the original old ones (without the "charge indicator"). My personal opinion is that the newer design's have less internal resistance or better battery chemistry and therefore can provide a bit more current that the older ones. The voltage is immaterial as the tools use a nominal voltage of 18v so it can range from roughly 20v to 16v and still work. The key is current for electromotive force I.E. it's current that gives the tool "oomph". That's as far as I'm going as my brain hertz now... All I know is the damn things work well with the new battery chemistry and new batts. Lol

Very interesting video One bit of advice, or a request if you like. You sound tok quiet and the tools too loud. Any way to sort that? I found myself turning the volume up and down throughout the video

Internal battery resistance is key. It indicates how much power is lost in the battery as heat. Bigger capacity cells tend to be newer technology with lower internal resistance, thus less internal power loss meaning more power for the tool. Also the 1.5 and 2 Ah cells have one row of batteries, 3 Ah and up have 2 rows halving the internal resistance.

Great video and comparisons. Have you ever tried the aftermarket 9ah batteries are they any good?

Curiously seems like the 5Ah performs rhe best. Which matches up with my research so far. The 18650 cells in the 5Ah have the highest discharge amp ratings for all the cells used in the various Ah sizes. The 6ah batteries have cells with a lower max discharge ratings. So if a tool can benefit from more amps, the 5Ah looks to be the best performer for power level.

The only time I'd expect to see a real noticeable difference in power output is between a 5 cell battery @18v and a 10 cell battery @18v. Regardless of watt hours. Beyond that I'd expect a noticeable difference between 18650 celled batteries and 21700 celled batteries.

i have a bosch impact drill 25618 and both bartteries that came with it was bat612 and they don't work at all and i don't understand why. i had it going on 3 years and i only use it once and i never charged them so i heard the battery died and the other one stays with 3 bars showing. so i want to purchase a high output battery for my impact drill

It seems that there is a difference between brushed and brushless tools. Also, I have seeen some people saying that the best makita battery is the 5ah, not the 6ah (first test kind of shows). Nice video, thanks for sharing.

What's the weght of the 2Ah?

Bel video, complimenti 🏆

That chainsaw is huge to be using batteries never saw that before.

Do you know what’s cell inside 3.0Ah please?

Good vídeo ,👏🏼👏🏼👏🏼👏🏼galera do Brasil vindo prestigiar ... Ferramentas em ação. . . Tmj

My old man is a fencing contractor. He is all ways driving the 150mm and 200mm batten screws with his Milwaukee impact driver and it gets bloody hot. Would a 1/2’ rattle gun be any better?

This really is more of interest with constantly running and torque dependent tools. You get into the falloff stage really fast on smaller capacity batteries, forcing you to cycle and recharge way to often since the voltage dropped so far that the tool only brings on 70% or so of it's nominal power. Technically the batteries are not yet empty, but the loss of power is so massive that you can't do any proper work. In such scenarios, I feel that everything under 3Ah just isn't usable. While 3Ah seems to be the sweet spot for my drills and my small circular saw, 5Ah seems to be a good compromise between use time and charging time for those power hungry devices like lawn mowers, string trimmers, sanders and grinders.

The difference in low drain tools is negligible. It's not noticeable until the amp draw of the tool approaches/exceeds the amp drain capacity of the battery. I don't think it about Amp/hours as much as the packs cell count. Depending on which cells are used, you shouldn't see much difference between batteries with the same cell count. Packs with 2 rows of cells should be able to deliver twice the amps of a pack with a single row of cells. That basic electricity 101. The battery controller could, however limit this, of course, and cells are getting better all the time. Used to be a rule of thumb that you could have high current or high capacity, but not both, depending on the cell chemistry and construction. That trade off may no longer be valid. You should see a significant difference in tools like circulars saws, especially when heavy ripping wet or treated lumber, larger impact guns, larger drills with large bits, and chainsaws, etc. As long as the tools amp draw is below the single row packs capacity, only the run time should be significantly different. Also, regardless of the advertising, the voltage does drop in lithium ion batteries as they drain. So a larger battery capacity should maintain higher voltage longer, which should translate to higher rpms unless the mosfets and other electronic doodads in the tool are able to trade amps for volts. Or, Makita does magic sorcery to defy the laws of physics. I don't have any single row Makita batteries, so I can't test it on my high drain tools. I only have Makita 5ah packs and most of the Milwaukee sizes. I have been thrilled with the performance, durability, and longevity of both brands. Great batteries.

Parafusadeira de impacto não força tanto a bateria.. A mola interna alivia o torque direto, sobre o motor.

I like the purple

Volume is way too low, we can't hear what you are saying?

Does someone have disassembled and compared battery 5 and z 6 ah?

Wonder why the 5.0 ah battery beat the 6.0 on the speed test on the impact driver?

Now what's only left is compare 1,5Ah with Makita power backpack with 4x6Ah ;)

Not much in it really, unless like what some other people have said - older batteries can't keep up with the demand that the tool puts on it.

Should’ve done it on grinders, they for sure feel way less powerful and my boss says it doesn’t matter even though I used a grinder for 2 years with 6 amp hours so I know a 6 has wayyyyy more power than a 3 . A 3 amp hour stalls wayyyyyy wayyyyy easier and just takes way more time but yeah anyways should have done it on grinders 🤷🏻‍♂️

My understanding is that the high ah batteries have a higher runtime typically, meaning they have more power available. Which means that they can work stronger and harder than smaller batteries, but idk, i don’t understand this stuff

It looked like the weight of the 6.0 steadied your hand and wonder just how much that contributed to a more efficient drill time.

As a drone maker and flier, here's how this whole battery thing works: the 3ah makita batteries were the original high discharge batteries meant for power gobbling brushed tools like the original LXT circular saw which I still have. The newer batteries like the 4ah+ were thought to have a lower discharge rate and thusly they were locked out from use in the original LXT set, Via a small tab that can be cut off. A normal 4-6ah makita battery has 10 18650 cells, any pack with only 5 cells (smaller) will not have that same discharge capacity regardless of ah. The modem 4-6ah batteries can handle the high discharge that the 3ah can because all makita batteries have a temp sensor for safety of the battery and the house. A 6ah battery should in theory be able to screw in twice as many screws as a 3ah, because it has twice the juice, think of a gas tank twice the size but nothing else is different, the engine could run longer but not have more horsepower.

Thanks for doing this. There are so many numpties that see a bigger number and think more power. They even try and argue the point inspite of clear irrefutable theoretical principals and demonstrable evidence. More power to you😁. Cheers.

Большое спасибо, было познавательно

Shame the battery chargers don't charge to peak voltage. They charge to a high storage voltage. The extra voltage gain would make a difference too.

The reality is that impact drivers pull under 200 watts so thats no where near the max sustained draw an 18v can output. Most of the time it is 800 watts. Try the 3, 4, 5 and 6 amps that all have 10 cells in a 5s2p config. The 3, 4 and 5 amp will have cells capable with samsung 25amps capable continous whereas the 6amp may only have 20 amp continuous samsung cells. Try this test again in a circular saw going down the grain in saw some 8x2 or 6x2. All makita packs that arent slim packs are great its just how Much you want to spend and how long you want the tool using it to last for. A 3 amp is lovely in an impact driver but not so much a 5" angle grinder. The 6 amp is great for the angle grinder and overkill perhaps for an impact driver....

Stop using them barbecue brickets…and use real wood barbecue coal instead. It burns hotter, and doesn’t impart that chemical stench to all your food. You’ll get a much nicer sear on your meat, and a much nicer flavor from the real wood coal (don’t confuse it with the wood smoking chips, though you can add them if you want a particular wood smoke flavor).

Nice impact driver, I got the same one except all black from Japan

hope you make video comparison made by china. japan. Singapore. Vietnam. I know what makes his board different. because in our country. we no longer know what original battery

What!? So just few seconds for $$$ more? Or did miss anything 🤔

I want that purple, but I don't know anyone that in china

sure you got more umff & torque with higher amp-powered cells if anything else is equal. if you in doubt, make a DIY cable with one of these RC AMP meters. (cost like 6buck 150A) and put it in between with some high rated silicone wires) and see what amp it affects, but can be numerous other factors that mudder the results, like protection circuits inside the power tool, but generally you will get more torque on a big amp pack than a smaller amp pack.

1.5 versus sex? You kiwis.

My batteries got fucked had 2x1.5 Ah But my driller broke pickup ran over my bag and it was in it) I inserted my battery to see if it still worked and that broke my battery. Good safety messures tho it didint blow up in my hand it overheated.

if your doing things that require alot more torque you will notice the power difference.

Wrong copmarison.capacity(Ah or mAh) shows the time that battery can provides a specifuc amount of current.but the torqe of a motor equal to voltage ×current.but low capacity battery voltage drops faster than a high capacity battery so after wile the low cap battery can deliver lower amont of power.so Ah of a battery×its nominal voltage is equal to its storage energy but for example 2 Ah battery can provide 2 amps in 2 houres.

Normal drill driver would do it much faster

No, more cells in parallel means more power
