Everywhere is screwed, sawn and stapled. Both in the professional and in the private sector hand-held power tools with battery or wired are in use.

Your cordless screwdriver, the jigsaw or another machine is not working properly anymore? Our power tool specialists offer professional assistance in the field of maintenance and repair of your equipment.

With or Without Battery?

Are you planning a new purchase because the previous machine can not be repaired? Or it no longer meets the requirements? No problem! In the land of DIY stores, the range of devices is endless. There are the machines in different price ranges, with or without extensions, for the professional and the home improvement …

But there is another difference: power tools with battery or wired devices. Especially in the field of hand-held devices, there is hardly a machine that is not offered in addition to the network variant with battery.

Note: Buy as needed! Calculate exactly what kind of work you need the power tools for. Which services are required? Also consider to what extent you will use the machines in the future.

To help you make the decision, lets compare both alternatives.


The use of power tools with rechargeable batteries quickly reveals a decisive advantage: mobility. Since the annoying cable pulling is superfluous, you can easily switch from A to B. Working overhead or in hard-to-reach places is easier to do. When dealing with small customer orders or on new construction sites eliminates the search for available sockets.

Another important aspect is the risk of accidents. There is simply no cable in the way that you can trip over! This circumstance will be particularly helpful in reducing the number of accidents in private households.

The Performance

Not only the craftsman, but also the “intensive” hobbyist and home owner needs machines with sufficient performance. The manufacturers have reacted. The development of new, high-performance lithium batteries goes exactly in this direction. The increasing use of brushless motors also increases the performance of the devices.

Cordless screwdrivers, hammer drill and angle grinder were yesterday. Today, pressing machines and agitators are also operated wirelessly. The market is ready for hot air guns and hot glue guns. By contrast, more powerful devices, such as concrete mixers or stone saws, will continue to be wired.

The Battery

Many manufacturers are working feverishly on the development of new batteries. It must not go unmentioned that batteries are among the wearing parts. In case of incorrect handling and unlawful disposal, they are also harmful to the environment. To regulate the policy has created a legal framework. With the battery law, the Federal Government implemented a European guideline for handling batteries and accumulators. To what extent this attention is, each individual can and must decide for themselves.

The Price

When choosing a suitable tool, the price should not necessarily be the decisive criterion. Of course, professional devices are generally priced higher settled. Nevertheless, I consider the above points to be the more important ones. In addition, power tools with a battery compared to the wired are a bit more expensive. This is partly due to the built-in brushless motors. This circumstance will certainly be eliminated by increasing production figures in the medium term.

Another positive development will reduce the battery as a significant cost factor. Under the leadership of Metabo, 9 manufacturers of power tools (July 2018) participate in the CAS (Cordless Alliance System). They use their latest battery development (18V, 1600W, 8Ah) with three other manufacturers is still negotiating. There are currently 110 tools that are compatible with the same battery system, and the trend is rising.

That’s a big advantage for the customer. He can even buy manufacturer-independent devices without battery and charging station, called “carcasses”. The price then corresponds to that of the network-bound variants.

Future Development

The trend is clearly towards power tools with battery. At the moment the ratio of battery and mains operation is 50:50. The study of the Böckler Foundation for the future of the power tool industry (2016) by Jürgen Dispan quotes the CEO of STIHL. He says: “Wired electrical appliances will not be around in ten years.” That’s a clear statement of how leading manufacturers judge the situation and adjust their supply accordingly.

In my opinion, it would not be justified to justify this development with one-sided marketing. The suitability and value of power tools with rechargeable battery has been identified on numerous small and large construction sites. Many craftsmen demonstrate their verdict with the fact that the sales of these devices steadily increase over the wired ones.
