The convenience of cordless tools is indisputable – they can speed up work at times, and “in the open field” are generally irreplaceable. But, alas, “wireless” models are still much more expensive than network models with comparable characteristics. However, sometimes you can save money: tools from the same manufacturer often use the same type of battery. However, not all and not always – so if you decide to put together a set of cordless tools, you should figure out which models of which manufacturer can operate on one “battery”.
Where to begin
The screwdriver is the most common cordless tool and often it becomes the basis of the kit: simply because it was bought first. But if you initially aimed at a set, the screwdriver should be chosen with great care – many manufacturers have models whose batteries are suitable only for them and not for anything else.
However, the point is to start assembling a set from a screwdriver, there is – due to the mass production, prices for screwdrivers are quite low. Therefore, the batteries included with them are usually much cheaper than if you buy them separately.
So, the Metabo BS 14.4 screwdriver complete with two batteries and a charger costs a little more than the same two batteries, but bought separately, even without a charger. This is also typical for other tools: batteries complete with them are cheaper, but with screwdrivers, the effect is most pronounced.
Unfortunately, manufacturers, not wanting to lose money, sometimes go to the trick and complete screwdrivers with batteries with a minimum capacity. Keep this in mind if you want to use screwdriver batteries with a powerful power tool like a hammer drill – and the hammer will not work properly and the batteries will quickly fail. If you are assembling a set of tools of different power and want to save on the battery, buy it in a set with the most powerful tool in the set.
Manufacturer and battery
When choosing a manufacturer, one should not be guided only by the popularity of the brand and personal preferences – the composition of the future set depends on it. Not all manufacturers produce, for example, cordless routers or polishers. If you need a special tool in the kit, make sure the manufacturer you choose makes it.
Additional requirements for the manufacturer arise from the operating conditions of the batteries – they will be used frequently and with different loads. There are no alternatives here: the batteries must be lithium-ion, and charging must be done with element-wise control – that is, each battery cell must be charged separately. Otherwise, you will have to change the batteries once a year, if not more often. Please be aware that not all manufacturers provide piecewise charging control.
It can be installed in screwdrivers, miniature reciprocating saws, jigsaws, miniature circular saws, impact wrenches, engraving machines, electric planers, etc. There is no element-by-element charging control in these batteries, but they consist of only three cells, so battery imbalance occurs infrequently.
The 18-volt battery type 1600A005B0 is used in the hobbyist series – more powerful tools.
These are screwdrivers, chain saws, angle grinders, reciprocating saws, renovators, jigsaws, circular saws, hammer drills, blowers, trimmers, etc.

Unfortunately, there is no element-wise charging control in these batteries either.
The 18 V battery type 1600A003NC is already used in the professional series and is equipped with a cell charge control.

The rest of the Bosch batteries are used in single models and are not suitable for assembling a set with one battery.
Renowned for the quality of its professional tools, the Makita brand also manufactures a wide range of cordless models.
They use Li-Ion batteries with a voltage of 10.8, 12 and 18 volts, but the most common tools are tools with an 18 volt battery. Makita batteries are equipped with point-to-point charging control.

The set of tools may include chain saws, powerful double-accumulator chain saws, angle grinders of various capacities, reciprocating saws with one and two batteries, renovators, angle drills, miter saws (two batteries), jigsaws, circular saws, wrenches, garden shears and brush cutters, trimmers , staplers, routers, polishers, etc.
The situation with the Metabo cordless tool is somewhat similar to the Makita: the manufacturer has several lines of batteries 10.8 V, 12 V, 14 V and 18 V. But 10.8 V and 14 V are used only in screwdrivers.
On the basis of 12 V batteries, Metabo produces medium power tools:
The advantages of 18 V Metabo batteries include element-by-element charging control and the ability to use LiHD batteries with increased current output, which is very important when working with a powerful tool like rotary hammers or angle grinders. The 18-volt series includes screwdrivers, drill mixers, angle grinders, reciprocating saws, renovators, miter saws, jigsaws, circular saws, impact wrenches, hammer drills, blowers, milling cutters, electric planers, technical hair dryers, etc.
The concept is clear from the name – one battery and many tools. This series uses 18 volt cell-controlled batteries.
Having a battery of this series, you can find almost any tool for it: a screwdriver, angle grinder, reciprocating saw, renovator, miter saw, jigsaw, circular saw, wrench, puncher, blower, brush cutter, trimmer, stapler, router, electric planer, vibration grinder, etc. etc.
If you are far from a professional and do not see the point in buying an expensive branded tool, do not worry: budget brands, albeit belatedly, are also slowly connecting to the concept of “one battery – many tools”.
