Archived from the Tools In Action forum (Bosch). This thread is read-only.
Bosch have always produced quality tools, trusted by vast numbers of users throughout the world especially Europe as real world tough, and developed through many years of interaction with end users and testers/reviewers to ensure the tool matches the application.
But have the blue giants of European tool manufacture got out of bed late this year?
Recent steps forward have seen the brush-less motor incorporated into the Milwaukee Fuel, the 4ah battery brought to market by Metabo and Dewalt who have been quick to follow suit and now they not only have brush-less technology but also the 4ah battery.
Does this mean Milwaukee will soon be bringing out they’re own 4ah battery very soon? ( we think so ).
Meanwhile Bosch have been busy producing new tools with very interesting innovations in laser levels, multi tools, upgraded rotary hammer drills and wood working tools designed to produce stunning results.
Developments in blade and drill longevity mean they now produce a range that last significantly longer than earlier products and most can be used in other manufacturers tools.
But I ask again, have Bosch pressed the snooze button on the alarm clock and missed the bus with battery development?
It remains to be seen if the German Giants have been busy behind the scenes developing something special to improve the runtime of they’re battery platforms.
but be sure Tools In Action will be watching Bosch,and our reporters will be letting our readers know the second we hear of anything. 🙂
It does kinda seem that way. While Milwaukee, Makita, Metabo, and Ridgid have created some buzz, Bosch seems to be sitting quietly in the corner. Maybe this is just the calm before the storm?
I hope so because they run the risk of losing valuable ground on the competition who are streaking away with new longer run time and power.
Bosch seems to me to be one of the more conservative tool manufacturers, with the few Bosch batteries that I do have, have been most dependable, so I’m not complaining if they are not the latest and greatest, I’ll take dependable any day. It would seem to me that most other manufacturers are putting in “hot” cells, that is cells that have a high discharge rate, to make a good show for the press, who seem to only be interested in how NEW tools perform. These “hot” cells work good for a short while, after which the performance falls off pretty quickly, and they do not have as long a life as batteries with “cooler” cells. If you really want to stay up to date with batteries the model electric car and airplane guys are always hanging out on the bleeding edge. They are already a generation or two ahead with Li-Po batteries.
I need to clear something up here about supposed HOT cell batteries.
This is a bit of a none starter because most of the batteries that were manufactured this way are now old tech and are two series ago.
The latest generation of lithium ion batteries do take longer for ions to return to towards the negative electrode during charging and require much more sophisticated monitoring during both discharge and recharge.
In general if you get a long warranty with the batteries on your tool it normally will mean they are not hot cells. 🙂

Exactly which cells are we talking about here, and in whose batteries?
Here is a “hot” cell, Milwaukees red lithium
http://www.keeppower…=92&Language=en
Here is a “cool” cell. Panasonics
http://www.keeppower…=94&Language=en
these are available today….
The latest generation of lithium ion batteries do take longer for ions to return to towards the negative electrode during charging and require much more sophisticated monitoring during both discharge and recharge.
And the manufacturers push the limits of these cells by insisting on charging them in one hour or less, without letting us have the option for an optimized charge cycle.
This seems to be a list of cells on a web site that are a near as damn it comparison but not the exact batteries used by a list of manufacturers.
I would be very interested to get the actual exact cell spec from several manufacturers and see how they compare.
Wayne Burgess wrote:
Forgive me asking but where did this information come from as the batteries your source shows as the ones in a Milwaukee red lithium have the wrong spec.
I linked from http://www.keeppower.com.cn, which specification is wrong? The 15m is a custom battery made for Milwaukee, spec sheets are hard to find…
There does also seem to be a lot of stuff on the internet where owners clubs dissecting and rubbishing each others tools which is not my gig at all.
With luck we will get feedback over time and find out how they have all performed.
I looked up the cells for several manufacturers batteries and they do not seem to be as quoted in some of these pages.
I am going to e-mail Milwaukee and Dewalt and others and see if i can get the exact cells they use so we can find out what is what.
I think it would be financial suicide for a company to give long warranty cover to a battery with such short term life cells given the amps needed to drive some of the tools out there.

That is why I recommend the remote control modelers, they are very brand agnostic when it comes to power tools, and are a lot more likely to sit down with a multimeter and figure things out. They do like to experiment too. The flashlight guys take batteries pretty seriously as well. Hate to say it but, they make us tool guys look lame.
Eco, what do you consider a short time in terms of cell life?

Anything less than 1000 cycles is a short life, even then 1000 cycles is still a pretty short life. I would prefer to see 2000 cycles. Some particularly “hot” cells have as short a life as 500 cycles, luckily, it would seem the tool manufacturers have steered clear of the really “hot” cells as they are even more sensitive to improper charging.

I have heard they deny a lot of battery warranties quoting normal wear and tear vs. the manufactures defects that the tools are warranted against. I believe most manufacturers can tell how many charge cycles their batteries have gone through.
You might find this review of batteries interesting
I have spoken to friends in the tool sales trade and now have a better understanding of some of the issues Eco is hinting at.
As you can imagine he is avoiding names of manufacturers as this opens a whole can of worms, but my spies tell me there are two manufacturers who knew they had sailed too close to the edge of the battery envelope and so have a policy of just keep quiet and replace the batteries with no quibble.
Although this seems like great after sales service what it actually means is oh shit boys we made a boo boo. LOL
All the manufacturers are pushing their batteries by charging them in an hour or less. I really wish we had some options on chargers to slow charge them when we have the time. Would be real nice to have this option on a multi-bay charger. I for one would happily pay (a lot) for this option even more so if it had some onboard diagnostics like a lot of the hobby chargers do. I guess the manufacturers think us power tool guys are just to dumb to appreciate any thing like this though.
I am wondering why nobody has made a charging system that allows you to add on slave docking bases which could be attached to the main charger allowing you to add several batteries being charged at the same time?
Milwaukee now producing the M12 with brush-less motors has made the gap even wider.
Will Bosch react and when they do will it be in a big way?
Bosch and Milwaukee are at about a tie when it comes to larger tools. Bosch has the better 36v circular saw and Bosch has three 36v roto hammers to Milwaukees 1 28v. I’ll give Milwaukee the Sawzall. None better in the 28v + class. Milwaukee also has the 28v grinder and band saw. Bosch has the option of slim pack or fat pack batteries, Milwaukee only offers the M28.
Each company seem to favor certain trades. Milwaukee seems to be catering to the plumbers while Bosch seems to be leaning more towards the masons. Plumbers like compact cordless tools, mason like big corded tools. Compare their line of demolition hammers to their lines of 12v tools.
Bosches latest radio is an improvement over their last version, Milwaukees newest radio doesn’t hold a candle to their older Rockford Fosgate model.
Boschs pneumatic line leaves Milwaukee in the dust. Especially when it comes to production tools.

Lith-Ion batteries require monitoring while they are being charged, a slave charger by nature would be the same as the main charger, otherwise there would be a lot of exploding batteries flying around.
For an education on Lith-Ion battery charging read Charging Lithium-ion @ Battery University.
Makita isn’t making many waves either. They put out a nice multi-tool about 2 years too late. I think we’ll see some big releases for 2013. I kinda get the feeling Bosch has something up their sleeve. If Dewalt keeps dominating the Carpenter craft, Milwaukee locks up the Plumbing, Electrical, and HVAC fields, Bosch snags a favor with concrete/masonry people, who does Makita cater to?

Makita caters to the Japanese, compare their domestic tool catalog to what they offer us. They easily offer twice the tools, we don’t even hear about their 14.4v Li-Ion line here. They even offer things like a cordless roto tiller and a Li-Ion bicycle.
P.S. Just found out they do offer a battery checker, I don’t think we can get it here in the states but Wayne should be able to pick one up in the UK.
Where did you find their Japanese catalog? I’d kinda like to have a look at that.
It is a step in the right direction but you still need a P.C to work with it.
Also Eco you misunderstand what I mean regarding a slave charger,I mean The main charger having monitoring capability for several ports into which the other chargers/battery holders would plug in.
Also the link you included seems to be a whole generation of batteries ago when the sophisticated monitoring equipment was not fitted to the tools.
There is a problem in general trying to optimise ion transfer rates at specific rates of charge and temperature when talking about lithium ion batteries and several versions using different chemistry, and all battery platforms are to a certain extent a compromise between end user demands for quick charging and runtime, but also of longevity of the life of the cells within them.
This makes sites like this forum very important in keeping people informed by giving real users a voice to let everyone know how the batteries REALLY perform. 🙂

Why would you want a charger that you could plug other chargers into? The simplest thing they could do would be to sell a simple slide on diagnostic tool, or they could include one on the charger like they do for those for the electric modeling crowd.
Milwaukees older V18-V28 battery service meter and a sawzall
Also the link you included seems to be a whole generation of batteries ago when the sophisticated monitoring equipment was not fitted to the tools.
My bad on the wrong generation of tools, I was annoyed that I could not find it retailed in the U.S..
Todays Makita batteries do include a battery management system (BMS) onboard the battery pack just like most of the other manufacturers, why do you think that all the battery rebuilders are not rebuilding Lith-Ion batteries? It is because they all include a proprietary BMS.

From their website of course
Beware it is a large flash catalog
Wow, a cordless Orbital Sander, Cordless Plate Joiner, and a motorized Bicycle. Dan and Eric could do a whole article about shit Makita doesn’t sell in the US. There’s something odd about Asain people being used in power tool adds. Why is that?

I’m really surprised there isn’t more of a grey market for tools like there is for electronics, the cordless tools use the same batteries.
You do know that Bosch does the same thing in Germany. They actually have two lines there, a line of green colored tools for the DIY crowd and the blue colored line that we are more familiar with. They even have a gardening line
Kind of makes me wish we had an American company doing the same thing…..
If I was in the U.S I would buy a generator that has a 240v outlet and use tools from both sides of the pond. 🙂

I have seen plug in converters, your right in suggesting a generator as the cheaper option. It would seem most of our battery chargers will charge foreign batteries, luckily. Saving my pennies for that new Protools PDC 18-4 LI set.
I have seen the Bosch Green line before. My understanding was that they were basically the same tools Bosch sells under the Skill name here in the States

Compare the previous Bosch link to Skils German website. Not the same, Skil is also an international brand.
Interesting Skil tracksaw
Now I feel cheated : (
Looks like Bosch has a few new tools coming out, at least in Germany….
A cordless roto hammer. The Bosch GBH 18 V-EC With their new 4 Ah batteries.
An L-Boxx based LED worklight, the GLI PortaLED
And a new 10.8v Radio, the GML 10,8 V-LI Professional
I’ve got a feeling 2013 will be all about Bosch. I’m thinking a brushless line with a few new tools in the mix as well.

I’m hoping that they bring in some of there Euro tools, I would love to see their tracksaws here. I’m looking foward to seeing more of the L-Boxx line here as well. Maybe Sortimo will get there act together and start retailing here to go along with Bosch selling their products.
They need to do something. The only real buzz they’ve generated lately was over that “work wear”. Their new tile saw looks nice.

Bosch has been releasing new accessories fairly regularly, some of them have been pretty good, like their Daredevil circular saw blades and their SDS bits with the solid carbide tips. They also have a line of production tools that has had a bunch of new tools released fairly recently.
I’m not saying they haven’t been producing anything, but they haven’t been grabbing many headlines. Does Bosch produce a brushless tool at all?

Yes, the new roto hammer I posted is brushless.
As hinted in the original title Bosch have been late to market with the 4ah and with many other of the new developments.
But the folks at Bosch have been busy,and expect to see them leapfrog into a very advanced position very soon with new technology and cool new tools. 🙂
Bosch has always struck me as a conservative tool company. They don’t always jump on cutting edge technology, but then again, they never really have any tools that perform poorly or that would be considered failures. They always have solid dependable tools and a lot of times that is better than hanging out on the bleeding edge of the latest technology. I know I’m not finishing any jobs if my latest wiz bang tool is broken in pieces on the floor, even if it was the latest greatest thing.
The new Bosch impact driver has a hybrid chuck combining 1/2″ square drive and 1/4″ hex. Looks very interesting.
That is one of the best ideas I’ve seen in a long time, yet so simplistic. It would have been nice to see it with a 3/8 anvil but that wouldn’t allow much side wall for strength.

That was my first thought as well, I usually prefer 3/8 drive for 18v tools because the sockets are usually thinner walled and able to fit into tighter spaces. It’s not like I would be using it to bust loose lug nuts. I know I will be giving Bosch a close look when it comes time to upgrade to a newer 18v set, as long as they loose that funky angled handle on their hammerdrill.
Yea I’m not a bid fan of that angle style drill either. Most application that I’d need a 1/2 impact on would require a high torque model.
I do like the idea and applaud the innovation though.
Bosch are set up for the European Building trade at heart I think.
Many of the features suit the type of fixings we use,and the way we build this side of the pond.
I wonder sometimes if maybe that means the tools of Metabo who are set up more for metal working,and Bosch,because of this do not transfer quite as readily to the U.S market.
Welcome back Wayne, hope all is well. I’d say that’s entirely logical.

Bosch tools are very common here in the states. Their roto hammers are probably the most commonly used, I see them on just about every jobsite. Metabo on the other hand are fairly rare. Our large retailers just don’t normally carry them. Advertising, I’m sure plays a large part in this. Stanley Black & Decker and all their brands are the only ones we are likely to come across advertisements for unless we are looking in trade or hobby type media, and even then Stanley Black & Decker rules the roost.
With all the differing types of construction here in the sates, I don’t doubt that there is a lot of crossover in building techniques. I would hazard a guess that even though our residential construction style is different, our commercial building styles will have a lot in common.
