At Thry....what brand of battery tools do you use? That could be part of the problem.

I've got an embarrassingly large collection of battery tools formerly required as a tradie, now for garden maintenance and hobbies, with the occassional bit of 'hard work' thrown in.

My brand is choice is Milwaukee which are far from cheap.
I have everything from 4ah to 12ah.
Standard.
High Output
Forge

Different types for different tools, but all fit in all.

Standard are good for drills, radios, nail guns, multi-tools, lights etc
High output are good for grinders, smaller saws etc
Forge are best for really high drawing tools that might bog down under load of normal batteries, drop saws, 9" grinder, demo-saws etc

I no longer own any petrol based tools, including lawnmower, whipper snipper, chainsaw etc.....all batteries.
I've got some batteries that are still going strong for well over a decade now, but yes, a few have died along the journey too.

I'm neither here nor there on EV's.

I see them as a way forward, but not necessarily the way forward if you get my drift.  I am not an early adopter of any technology so have kept my distance (we have bought 2 vehicles since 2008, and both are Petrol cars, one of which was bought 2017, the other in 2024 to replace a 2008 car that probably had another 5 to 10 years in it, but became cost benefit to ditch in favour of something else, because that car was in need of more maintenance than I liked.

The main reason not to go EV, was more cost vs benefit at the time.  The car I bought was cheaper than the average good EV, and we didnt need to put a charging station in for it which made petrol win.  I also liked the shape of the car I bought, over what was on offer equivalent.  We gravitate to what we like the look of generally, be it food, scenery, choice of partner, etc. 

I have no feedback for the validity of EV.  I can only talk about rechargeable batteries in power tools, and solar panels for xmas lights and I have mixed fervour for them.  I find the battery powered tools to either be under powered, or unable to last the duration required to get the job done but thats not really a true comparison.  Xmas lights get stored for 10 months of the year, are made from NiMH and usually sit there and degrade in the process which limits their longevity.

Ive switched to plug in lights purely because they are brighter and more reliable, but the solar ones have their use cases such as range and isolation. 

Anyway, thats my two cents.  I had the Tesla's as a rule, but its more bout Musk, and his business model than anything else.  Subscriptions in general annoy me.


Got no interest in EV's as the economics doesnt add up unless you are doing plenty of kms or are prepared to take a money hit for the environment(sorry Greta T). Had no trouble with Lithium batteries for power/garden tools either the expensive brand names or the cheap knock offs and we used Renogy lithium batteries/solar panels in our little Campervan and they were fine for years.

Milwaukee seems to be very popular with tradies Kruddler.

Our new neighbour is a glazier and a Milwaukee man.  He and his wife are from Western District farming families but they’re new to rural living.  He was impressed with my Honda brushcutter but I suggested that he explore Milwaukee battery powered gear rather than ICE tools.

A friend bought a new car recently.  She was intending to get an EV or hybrid but the salesman demonstrated that she didn’t do enough Ks and an ICE vehicle was her best option economically and environmentally.

My V8 diesel simply doesn’t have an EV equivalent, unless I’m willing to shell out much more than I can afford. Ms DJC’s coupe now comes in hybrid and EV versions but the ICE model runs on the smell of an oily rag and replacing it doesn’t make sense.

bosch.

Depends on the use case too.  Go through any decent materials and it gets a bit hard.

There is a significant point of difference between battery life in power tools and vehicles, and if you examine figure 2 in the link northernblue offered you see why.

Range is already a hurdle, and the article tries to spin nearly a 2% drop off per annum as a positive. But the harsh reality is many EV engineering solutions will fail as dysfunctional at levels below about 80% capacity due to battery protection measures. It's the same for high end UPS and that application has no battery technology restrictions at all, vehicles aren't at the cutting edge.

Energy isn't a magic pudding, a degraded battery isn't like a half full tank, in fact a degraded battery is the exact opposite of a half fill. A half full tank gives me more performance and greater efficiency due to reduced weight, a degraded battery is a boat anchor because at empty it is still the same weight.

In electrical engineering power is the product of two parameters, voltage and current, when batteries degrade are you lose both and you are always starting that much closer to the functional minimums at which the vehicle will just switch off. That is the difference between usable capacity and total capacity.

I'm not arguing 100% failure rates, but the EV marketing and green evaluation you read largely ignore reality, and all that is on top of the dodgy corporate practises. What some of the EV makers are doing is as bad as what Volkswagen did when it defrauded the public about emissions.

I'm not even going to start with the manufacturing side, that's Nimby.

Green or blue?

Blue is the tradie stuff.
Green is the DIY stuff....and even then there is a difference between some blue atuff sold at bunnings and some blue stuff you buy at a tool store. My mate found that out the hard way.

Bosch blue is decent. You want to have 18V stuff as a minimum for power tools, and higher Ah gives higher runtime, but also better peak power over its charge cycle.
 
There is also some different versions of their batteries....i believe the procore is the newest and best one. They had a a 36 or 40v one for the power tgirsty stuff too.

Essentially if its bogging down youve got the wrong battery.

It's interesting about the "where you buy" issue, because they all look basically the same on the outside, but they aren't the same on the inside.

FWIW, all the brands do it, Milwaukee, Dewalt, Bosch, Makita, Hitachi, etc., etc.. they have a big box store quality and a trade quality. You do not really see the difference until you either pull them apart or go to have them repaired.

The Bosch Pro Brushless stuff is pretty good, but I don't think you can buy that series from Bunnings although I believe with the start of Toolkit Depo that may be changing. Also once you register Bosch Pro Series on the Bosch-Pt website you get a 5 or 7 year warranty on most things. That was the main reason we went with Bosch Pro at our work, most other brands limit commercial or trade warranty to 6 months or 1 year.

But we always have the debate, should you buy the cheaper tool and replace it every year, or buy the better tools that lasts a few years. The answer is not straight forward if you are close to replacement suppliers, but if you work remotely the better tools are the go.

Thry, 2.5ah is like an electric toothbrush for a power tool battery, I wouldn’t bother using anything less than than 5ah, I also have 9ah, that’s AEG register online and it’s 3+3 warrantee.
I’m not aware of the quality being different between stores… possibly “exclusive” models perhaps ?
Milwaukee, AEG and Ryobi are all owned by the same company apparently.
I’m told the tech starts in the Milwaukee brand and gets handed down to AEG then Ryobi, I can’t verify that.
I did have an AEG 125mm grinder that the switch had crapped out so I put it in for repair (out of warrantee) quote was $200 !
$230 later and a new grinder…
Let’s go BIG !

ive got the green ones. Power for all 18v lithium ion. Im not complaining about them they do the job, i needed a drill when my motor blew up and picked up a pack at bunnings that was 150 when we renovated our house back in 2015.  Came with a drill and an impact driver, two natteries and a tool bag.  I knew at the time the blue was better but the tools were so much more expensive i just went with the weekend warrior stuff and its served me well.  Got the jig saw, circular saw, reciprocating saw and a bunch of other stuff really cheap when masters went under.  Their hedge trimmer is fantastic, its the blower thats chewing through juice.   Drills are fine, the electric saw is mixed (circular is only good for small jobs but thats fine for me as ive got a table saw with a makita circular saw, and ive also got a hand me down ryobi that was bought from mcewans which is going to outlive me (both ac powered).  I know about the amp battery differences but until the blower changing batteries has been fine. Ive had these tools a while but the blower is the first one where I have 5 batteries and have not been able to finish the job without waiting for batteries to charge (the grey ghost gum that dropped its bark is the main reason why though). 

I try to buy good affordable tools rather than cheap shut which is why bosch green fit the bill. 

Ultimately whilst you can get bigger batteries and tools that will do that job like you guys say its a cost benefit thing.  If I had more expensive tools with bigger batteries odds are I wouldnt have made much use of them (and those batteries would likely be half dead by now anyway).




Im not complaining about them overly.   They do the job but observationally some tools are better than others and it would be true across any manufacturer.  Not because the tools are better or worse, they give you more cutting power or blowing power to go with the increased amp battery.

Most of the expensive brands are now made in China as are all of the batteries, I was a Makita fan as they were mid ranged priced and reliable and were USA and Japanese made but now they have joined the other brands in getting their stuff assembled in China. Think you can still buy Japanese made Makita in Japan but its very hard to get.
Not a fan of anything Bosch, a family friend had a Bosch dishwasher that set fire and burnt down part of their house but Bosch were unhelpful and their customer service poor as they tried to avoid responsibility even though the control board in the door setting fire was a known problem.
Had a liking for Hilti and Hitachi power tools back in the day as we had them at work for the elec fitters/linesman/techs but they were at the expensive end of the scale so Makita got a lot of my business.
