Stihl battery strimmer – These models are recommended

Stihl FSA 45

Cordless FSA 45

Even among the high-quality cordless strimmers from Stihl, there are inexpensive offers. A particularly good value model is the Stihl FSA 45 .

The unit works with 2 plastic blades. Due to their low air resistance, they ensure an uninterrupted working time of up to 20 minutes. The 36V battery has a capacity of 2 Ah and is permanently integrated. So when it is empty, a break must inevitably be taken. Due to this fact and the cutting width of 23 cm, it must be stated that the device is more suitable for smaller-scale work.

A weight of only 2.3 kg and the height-adjustable handlebar ensure easy handling. Furthermore, you can flexibly adjust the angle of both the handle and the motor head. The head can be swivelled by 90 degrees, which makes very accurate edge care possible. The handle on the motor head, which prevents contact with problematic objects, is also worthy of praise. In addition, the noise level is kept to a minimum.

All in all, the FSA 45 is a comparatively inexpensive battery-powered lawn strimmer from Stihl. Nevertheless, it has a battery voltage of 36V. However, since the battery is integrated, the potential area performance suffers. The device is better suited for effortless use around narrow passages. The remaining battery capacity is displayed via an LED on the outside of the housing. Thanks to the low weight of 2.3 kg, women and senior citizens also enjoy carefree comfort.

Stihl FSA 57

Trimmer FSA 57

Stihl’s range also includes battery trimmers with replaceable batteries. This allows you to extend the runtime as desired. One recommendation in this context is the Stihl FSA 57 .

In the set, the device is delivered together with a 2 Ah battery and the matching charger. An LED display indicates the available capacity at all times. A nylon string is used as the cutting system, which provides a cutting width of 28 cm. Accordingly, you can expect a good area performance. If required, the manufacturer’s plastic blades can be used as an alternative.

Here, too, the shaft can be adjusted to your own height. The handle can also be adjusted. At 3.5 kg (including battery), the weight is somewhat higher. However, the soft handles make it comfortable to use. Furthermore, a protective handle is also installed here, which prevents contact with sensitive flowers and the like.

In summary, the FSA 57 is a recommendable battery-powered lawn strimmer from Stihl. It is offered in a set with the matching accessories so that you can get started straight away. A voltage of 36V and a cutting width of 28 cm ensure a reasonable area performance. The nylon string is ideal for working directly on the obstacle.

Stihl FSA 90

Grass FSA 90

You can even carry out extensive area work with a Stihl battery-powered lawn strimmer. Impressive proof of this is the Stihl FSA 90 .

This brush cutter has a great cutting circle diameter of 38 cm. Accordingly, you can make rapid progress even in extensive areas. The included AP300 battery also guarantees continuous operation for up to 30 minutes at a time. The ECOSPEED function allows you to maximise the runtime if necessary. By the way, the two-thread cutting head extends itself automatically when you press the AutoCut motor head on the ground.

Although the mower has such an extensive area coverage, it still weighs less than 5 kg including the battery. The height-adjustable handlebar and the adjustable 2-hand grip further enhance ergonomics. In addition, a double-sided shoulder strap is included in the scope of delivery. You can relieve the strain on your arms and distribute the total weight evenly over your torso.

Overall, the FSA 90 is a high-quality cordless lawn strimmer from Stihl. It is ideal for maintaining large areas, as the nylon string has a cutting width of 38 cm. The belt system, among other things, ensures a high level of comfort. In addition, the brushless EC motor and the voltage of 36V can also reliably cope with taller vegetation.

Stihl battery strimmer – You should generally pay attention to the following


Battery-powered brush cutters compete with 2 other types: corded brush cutters and petrol brush cutters. Like the other types, battery operation has both advantages and disadvantages.

Basically, cordless trimmers are quite handy, which is mainly due to their moderate weight. The brushless motor starts conveniently at the touch of a button and does not emit any unpleasant odours. Moreover, it does not require any maintenance work, as is inevitably the case with a petrol engine.

Thanks to the low noise level, you don’t have to wear hearing protection and can expect stress-free handling. Because the sound level is kept within limits, they are a perfect choice for working in sensitive areas, such as hospitals.

In contrast to a cable trimmer, you can work on any desired location immediately. Therefore, it is also possible to simply load the device into the boot and use it in remote locations.

The Stihl battery strimmer is powered by either an 18V or a 36V lithium-ion battery. Depending on the model, you can either remove or replace the battery flexibly or it is fixed in the system.

Furthermore, it has to be said that cordless brush cutters are not intended for large resistances. Even the Stihl machines cannot cope with branches and roots due to their power and cutting system.

Cutting system

The cutting system is the central element of every lawn trimmer. If it doesn’t work properly, nothing else matters. A Stihl battery-powered brush cutter works with either a nylon thread or a plastic blade. Some of the devices are pre-equipped for both.

In terms of efficiency, the blade is superior to the nylon string. It has less air resistance, which means that the battery lasts longer. In addition, the natural wear and tear is somewhat slower. A major exception is contact with durable objects – here a plastic blade shatters almost directly. The Stihl battery-powered brushcutters can have a compartment in which several spare blades can be stored.

A nylon string is the optimal choice for care directly at the obstacle. If it comes into contact with wooden edgings, stone slabs and the like, no mutual damage occurs. You can therefore work along edges and obstacles without complications. Over time, the thread becomes shorter and the results tend to be poorer. Then it has to be lengthened. At some point it will also be necessary to change the entire spool.

No cordless brush cutter can cope with branches and really dense vegetation. For such purposes, a petrol model with a steel blade is still the best choice.

In addition to the type of attachment, its cutting width also plays a role. The more pronounced the latter is, the faster you will make progress with your project. If, on the other hand, you want to work very precisely in a confined space, a smaller working width is more advisable. In the battery trimmer segment, however, the differences are not that great anyway.

Power & runtime

Of course, the power is also important. It does not necessarily have to be very high, but rather suitable for the conditions on site. Even a cordless lawn trimmer from Stihl does not promise miracles in this field.

In general, unfortunately, the performance cannot be reliably determined from a correct indicator. One place to start is the battery voltage. The 36V models tend to have a higher power potential than the 18V models.

The power consumption, which is shown in watts, can also indicate the potential power. Increased power consumption per unit of time can go hand in hand with more power. However, this need not always be the case.

Another useful feature in the fight against adversity is a high speed. It helps you to ensure that the unit does not collapse so quickly in the face of greater resistance.

To get an idea of the range, you should also consider the battery capacity. It is given in the unit Ah (ampere hours). The higher the value, the longer the battery will last in continuous operation. A Stihl battery strimmer can be operated with a backpack system of up to 31 Ah, which is in principle enough for the whole day. As already mentioned, however, some models are supplied with a permanently integrated battery. In this case, the runtime can no longer be extended by quickly replacing the battery, for example.


Handling the lawn trimmer should be as comfortable as possible. In this case, the process does not feel like a chore and can even be fun.

A light weight is the main factor that contributes to energy-saving handling. A Stihl battery-powered brush cutter weighs only 2.3 kg including the battery (FSA 45). Such models are of course best suited for women and senior citizens.

Furthermore, a height-adjustable telescopic handlebar ensures that people of all sizes can work in an upright position. This delays the onset of back problems for as long as possible.

In addition, the black front/handle can often be adjusted in its position. This further promotes personal ergonomics. Soft grip surfaces also prevent unpleasant vibrations and the formation of calluses in the palms.

The motor head can also be tilted and turned. This is important so that the cutting system can maintain a horizontal position to the ground in every area. With a Makita battery-powered brush cutter, you can therefore also take care of lawns, curbs and hills.

As already mentioned at the beginning, using a Stihl cordless lawn trimmer is intuitive and effortless. The devices are delivered pre-assembled so that you can get started straight away. No strenuous tightening is required. A 2-hand switch, an additional key and the enclosed safety goggles ensure a high level of safety.


The volume can also become a significant factor in everyday use. If it is too loud, it can have a negative effect on your health and stress level. In addition, there may be problems with the neighbourhood or even the regulatory authorities.

Fortunately, a Stihl battery strimmer is commendably quiet. That’s why you can actually use it even during lunchtime. A sound level of less than 80 dB at the ear reliably prevents hearing damage in adults and ensures that the neighbourhood does not feel disturbed.

In general, cordless trimmers are the quietest machines in the brush cutter segment. For this reason, they are the best choice for green maintenance at schools, nursing homes and hospitals.


Of course, the costs also influence the decision. They should always be in a fair proportion to your own requirements. In the cordless brush cutter segment, a surcharge is necessary for increased power potential and increased area performance. In addition, sets including battery and charger also require a higher budget.

A Stihl battery strimmer is clearly a quality product. Nevertheless, some of the compact models are available for less than 200 Pounds. In general, it can be said that a professional cordless model is somewhat more expensive than a corded model (this is also true for other manufacturers).
