The batteries aren't rated in Amps (A), they're rated in Amp-Hours (Ah), it's a measure of electrical charge capacity in the battery eg a full 4Ah battery has the capacity to deliver a current of 1A for 4 hours or 2A for 2 hours etc. Electrical power (Watts) is found by multiplying current x voltage eg 1A at 40V is 40W. Electrical energy (Watt Hours) is found by multiplying power x time eg 40W for 4 hours is 160Wh. So, if you want to know how much energy is in your battery, multiply the capacity (Ah) by voltage (V) eg a 4Ah battery at 40V is 160Wh

[@Patrick-857]

I hate how batteries are still rated in amp hours. It's a crappy unit of measurement that is redundant and unfit for purpose. They should all be rated in watt hours because watt hours don't depend on voltage. With 12v, (actually 11.1v, same with the BS about 20v, 40v and 60v) 18v, 36v and 54v all being common now, amp hours become complicated to figure out for most people who don't understand electricity. To the point where they actually think the Dewalt Flexvolt has less runtime at 54v because a 6AH goes to 2AH. 2A at 54v is 3 times the wattage of 2A at 18v so... With watt hours the math is already done because watts are a unit of work, the bit people actually care about. Amps mean nothing without knowing voltage, unless you are worried about wire gauge or something.

[@scottstewart6624]

Scott, you were wondering about the battery life. If you look at the side, it will say 2.5 Ah, or 4.0 Ah.This is because batteries are rated by Amp-hours. The tools have a given Voltage, 18 V or 40 V. So when they work harder, they draw more current. Current is measure in Amps. An Amp-hour is a way of measuring how much energy a battery stores. It's current x time. A 2.5 Amp-hour batter can draw 2.5 Amps for 1 hour. Or it could draw 0.5 Amps for 5 hours. Or 5 Amps for 0.5 hours. In all these cases, Amps used x time = 2.5. So a 4.0 Ah batter stores more energy than a 2.5 Ah. Again, you could draw 4 Amps for 1 hour, or 0.5 Amps for 8 hours, etc. Hope that helps!

[@bertbergers9171]

I watch some guys explaining tools on another channel. They are allways going on about battery's being built up of rows of cells and the rows being connected in parallels. And going from 2,5 to 4 would bring in a second row, which would increase the amount of amps you can draw at the same time. And since power = voltage x current beign able to draw a higher current (amps) you can deploy more power in a moment. That's why to me that hammer drill on 2,5 seemed a bit of a bad idea, luckily nothing stuck real bad (increasing the power demand).

I have used my heat gun and Festool midi vacuum and it's been great.

[@stevemckewen1046]

This is how batteries sizes work. The power from a tool is not determined by the battery - except that high power tools often cannot use a small battery because it can't provide enough power. The energy in the battery (the amount of work it can do, how long it will last) is determined by the voltage x Ah. That means that a 4Ah battery will last twice as long as a 2Ah battery. Also a 40V 2Ah battery will last twice as long as a 18V 2Ah battery. A 40V 4Ah battery is 4 times bigger than a 18V 2Ah battery. Also a 40V battery can be operated more efficiently than an 18V battery.

Regardless of what other viewers will say, I find run time to be the major limit. I was drilling 7/8 (22mm) step bit holes into steel with a milwaukee 2704 and managed to drill 2 holes with 2 3.0AH high output batteries before they died from full charge. Battery life was much better with my German made Metabo SB 18 LT BL with 2.0 AH batteries. I managed to complete the project with the 2 batteries from that kit drilling about a dozen 7/8" (22mm). Maybe milwaukees battery technology just isn't there yet (but I also don't buy many of their tools because the quality isn't there). In a similar fashion, it took a fully charged 4.0ah De Walt battery to cut thru a piece of 100 mm steel pipe for a plumbing drain. If you only have 2-3 batteries for the day, you'd be out of luck after cutting that pipe. I think every tradesman should have a electric copy of the cordless tool in their truck or shop just in case.

Has happened which required the partial disassembly of a battery, easy fix.

I had to rotodrill honestly about 300 holes and we needed to use sds bits that had vacuum attachments or silca filled dust would just be insane, I tell you that to tell you this that mikita portable hepa vac is the best tool made its small and powerful and works amazing!

[@berenlea486]

If you want a something that would massively improve a cordless job site putting a small inverter and solar panel in your van hooked up to the battery is super useful all it needs to do is power 3 or 4 chargers but it means you can have fewer batteries while working for as long as you choose to

Love the vids Scot

[@andrewcarr2431]

The Amp hours is based on the design of the battery cells inside the packs, some battery cells are connected in parallel thus allowing more output or more runtime under reduced load. Generally there is a circuitry inside (logic) that changes the output depending on the load. More powerful tool = higher power output, less powerful tool = longer runtime with the same battery. Each manufacturer has their own marketing around their tools, but that is the theory anyway. I know my old 18V dewalt driver is more powerful than my newer 20v slimline model. But obviously the older tool is more heavy to use. Different tools for different jobs. Now i could purchased a higher amp/hours 20v battery for my new drill but I use it for drywall and like the lighter tool when working, so I just have 2 batteries going one on charge and one in the tool.

[@MrTooTechnical]

Kick ass. As long as makita is your primary tools. I’ll keep watching. Woohoo

[@rickpolicastro5474]

Love your video's!! Just a note.... if you have to charge a battery, you could buy an inverter... just a thought.. Again awesome video's and work

[@NZKarlos79]

Definitely yes, I'm getting a new house built and they have all but finished with no power connected. The only trade that needed a generator was the plumbers, mainly because they didn't have the cordless tools available.

[@jonathandevries2828]

Hey Scott Brown Here, I have the same Milwaukee packout system i love it!

[@Mudder1310]

I was a cable guy in the mid 90s. We used to carry around the light socket plug adapters. My first cordless tool was the 9.6v Makita drill with the long handle. Even then it was a game-changer. It wasn’t long until 14.4v came and cordless drills and impacts were practical for commercial work. Now I only have corded tools for big stuff, table saw, drop saw, or too spendy to justify like my Hilti SDS max rotohammer.

[@ryanslut5607]

I have a 22v hilti drill. Really good tool. Expensive batteries tho.

[@shaunmurray2396]

I’m an electrician, have a couple of corded tools, not many. Have an inverter and battery and charge the tool batteries while on site or driving. Always have 5 full batteries at the ready

[@sylviabrown9186]

Enjoyed your video always look forward to them 🙄

[@wearsjorge55]

It really depends on the specifics of your job. Domestic electrical work, corded tools are wonderful from start to finish from your little hammer drill to the big one to the multi tool to the vac. Commercial servicing which is what I do now, I've taken all my corded tools out because having to set up leads for jobs takes too much time. Time is so much more important here than it is in domestic so the cost of a cordless vac was worth every cent

[@vdognz1]

I’ve been cordless for 3 years started with Makita because I had a 6 piece kit so just brought more skins.So my van for the boys is Makita then I fitted out my Ute with dewalt and loving it. Leads are old school and it’s painful watching apprentices pack them back in the van

[@welshman100]

Love the electrician.

[@f.demascio1857]

I just bought a Milwaukee cordless pipe threader. It came with two 12Ah batteries (18v), $1800 USD. Not going to get rid of my corded Ridgid 700 (yet.)

[@michaeljacobs9613]

For all my tools, I tend to get them with the Battery + Charger --> I now have a DeWalt charging bank of ~6 chargers = No down time :D

[@chrisb4009]

There are three killers for cordless tools. 1) The time you save running out cables you spend double messing about with charging at home. 2) The tools cost significantly more and are generally less powerful. 3) The tools are more complex so don’t last as long as the mains stuff. A third factor is you’ve gone from using the clients power to do jobs to using your own. It may seem silly but if you use £2.5 in electric charging all your batteries each night. That’s £600/year straight out of your profits.

[@fireblaster9961]

You can go cordless but only with riches tools also lol 🔥🔫

[@cdurkinz]

I have that Milwaukee table saw, it's amazing.

[@Rompestromper]

I work fully cordless, I work a lot in farm and shed building without any powersource near. My van is equipped with some solar panels and even in de winter (less solar charge) I can charge all my batteries if needed without any problems. For me this has been the easiest and cheapest option because generators are more expensive in fuell and sometimes maintainance then buying the tools etc. I mainly have DeWalt flexvolt and Hikoki/Hitachi/Metabo HPT multivolt equipment. Also I believe your Dewalt table saw is of larger blade diameter compared to the milwaukee right? this is probably also a weaker saw when corded I think. love the video, great subject!

[@rogerbayzand4455]

We had an early Makita drill (the one with the long battery in the handle) in the boatyard in the mid 70's and it was an instant hit, especially if you had to do a job up a mast. It's such a shame that you get caned for replacement batteries or they change the shape of the connector yet again. Another great video Scott.

[@ryanslut5607]

Haha the cord alone would have been a right pain in the ase up a boat mast haha

[@sparkywit]

13:02 I'm always moving distribution and consumer boards. To save me wasting time setting up temp supplies for fridge/freezers or get them back online as a priority. I went all cordless a long time ago and invested in a petrol generator. Working in the industry helps to have both electric and cordless. If it saves hassle and makes you more efficient, it's worth the investment. 😁

[@supergimp2000]

The Makita 40V has the same number of cells as the 18V LXT. So for a given number/type of cells, for example, you get 40V at 2.5Ah or 18V at 5Ah. Note that while people refer to "5 amp battery" it's really a 5 Amp HOUR battery, referring to capacity. A 4 Ah battery can deliver 4 amps of current for one hour, 2 amps for 2 hours, etc. At least nominally (given test conditions). (The voltage rating is nominal, 18V and 20V are essentially the same given various test conditions)

[@texasproud3332]

As a licensed electrical contractor I very rarely use a cord because I have inverter mounted on my truck and plenty of batteries and multi chargers never run out of power so all good

[@Raphioso]

How it works with the Amps (or better amp-hours): 2.5 Ah battery: you can (theoretically) draw 2.5 amps at the given voltage (18/40) for an hour out of the battery before it is empty. 5 Ah battery: you can draw 5 amps for an hour. As it is multiplied (Ah = amps x hours), you can also draw 2.5 amps for 2 hours out of the 5 Ah batteries. So Ah is a measure of capacity, not of how strong the battery is, and is only comparable in one voltage class (20V 2.5Ah is half capacity of 40V 2.5Ah). Because of the internal structure of the batteries, it's often better to use batteries with a higher Ah rating for tools that need more power (think angle grinder, hammer drill, saws) I hope that makes it clearer, feel free to ask if not

[@JaySellers]

I installed marine electronics and electrical systems for 7 years in a past life. Nothing gets more confusing than trying to explain house battery voltage, load and amp hours to new live-aboard yacht owners.

[@Patrick-857]

They mostly will never understand, matter how you explain it.

[@yup3398]

That vacuum looks great.

[@AndrewStrydomBRP]

For me, the main thing that still has to be corded is my proper M class dust vaccum and wall chaser (our walls are mostly masonary here in the UK), I have a little L Class/Hepa vaccum for quick run around dust collection and even with my massive 180wh/18v 10AH metabo LiHD batteries it doesn't last long enough to do too much on the boost mode, and I have no doubt that the 1900w metabo wall chaser would last far too short of a time on batteries to do enough work with it, not to mention that the only wall chaser I know which is cordless is the dewalt which with batteries alone and no vacuum cost as much as the corded vacuum, chaser and multiple blades did, plus it's worse at dust extraction and doesn't really support the triple blade that my corded one does which is a major time and mess saving. My corded heat gun also comes in handy as keeping the cordless one on for long periods will completely sap the battery dead within too short of a period to be practical, plus the cordless has no trigger lock. The main issue I have is not so much the runtime though, but the insane cost of the batteries, I consider metabo cheap for batteries but even so, 8ah is 100 quid, 10ah being 130-150 quid (and those are good prices), it's not practical for me cost wise, larger dewalt batteries are even worse, which is one of the reasons I went metabo for some of my stuff, while the rest is dewalt. Something that also must be considered with batteries is the limited lifespan of them too, you will only get 500-1000 charges out of them, if you're fully discharging and charging each battery every day, those batteries won't last you more than a year or two, and for the price of them that starts to get very very very expensive, a calculation that should be considered is what the battery lifespan is (how many times it will charge) divided by the cost of the battery, you might get a shock at how much it costs you each time to charge the battery just on wear, not even power costs. Everything else cordless that I have; Heat gun (i don't generally need it for much more than shrinking tubing), impact, drill, grinder, mini recip, elec screwdriver, multi tool, SDS w/ built in dust vac, radio, my two work lights and a couple more things, I am all more than happy with. I'm an electrician so I don't need most of the woodworking tools hence I can't comment too much on those, but what I use is all good. I would also recommend if you have the know how, make yourself a corded battery adaptor (i'm planning to do for both my dewalt and metabo kit asap) and run anything that doesn't need to be cordless all the time - like lighting - off the wall so you are saving those valuable charge cycles on the battery. It's just the very high power devices such as vaccums, heat guns, large 150-230mm 1500w+ grinders, compressors and the likes, that I don't consider ready enough to go cordless on. Especially for the prices they are going for, as you can generally say that a corded tool costs about a third to a half of what the cordless version plus a battery or two would cost you.

[@paphaju1]

The reason why you can run longer the 40 V 2,5 Ah is, because it stores more energy. The power what is capable to deliver is the multiplication of voltage and current (40*2,5 ). Plus you are runing the tool on higher voltage can lead more performance -> quicker work, therefore you run the baterry for shorter time.
