Buying Guide: How to Choose a Battery Operated String Trimmer
I’ve used my fair share of string trimmers over the years, and making the switch to a battery-powered model was a game-changer for my yard work. No more wrestling with a pull cord or dealing with gas and oil mixes. But with so many options on the market, how do you pick the right one for your needs? Let me walk you through the key things I consider before buying any battery operated string trimmer.
First, think about your yard size. This is the single biggest factor. If you have a small or suburban lot, a trimmer from a smaller tool brand or one that uses a smaller battery platform might be perfect. These are lighter and easier to handle. For larger properties with thicker weeds, you’ll want a more powerful tool, often from a major brand like EGO, DeWalt, or Milwaukee, that uses a larger battery. More power usually means a heavier tool, but it also means you can get through tougher jobs without the tool bogging down.
Next, pay close attention to the battery system. This is the heart of your tool. If you already own other cordless tools from a specific brand, it often makes the most sense to stick with that same ecosystem. This way, you can share batteries between your drill, your blower, and your new string trimmer, which is incredibly convenient and cost-effective. Look at the battery’s voltage (V) and amp-hour (Ah) rating. A higher voltage generally means more power, while a higher amp-hour rating means longer runtime. For most people, a model in the 20V to 40V range is a great balance of power and weight.
Then, consider the cutting swath. This is the diameter of the path the trimmer cuts with each pass. A wider swath, say 15 inches or more, lets you cover ground faster, which is great for big, open areas. A narrower swath, around 12 to 13 inches, offers more precision for trimming around delicate plants and tight corners.
Don’t forget about the feeding system for the trimmer line. I’ve spent too much time banging a trimmer head on the ground to advance the line. A bump-feed head is common and works well—you just tap the head on the ground while the tool is running to release more line. Some higher-end models have automatic feed systems that advance the line for you, which is a nice luxury. Also, look at the adjustability of the shaft and handle. A telescopic shaft lets you set the perfect length for your height, reducing back strain. An adjustable handle also helps you find a comfortable and balanced grip.
Finally, think about extra features. Many of the best battery operated string trimmers for your yard can convert into other tools like an edger, a brush cutter, or a pole saw with attachment-capable heads. This versatility can be a huge value if you need more than just a trimmer. Also, check how easy it is to load new trimmer line; some heads are frustratingly complicated while others are a snap.
FAQ
How long does the battery last on a single charge?
This is the most common question I get, and the answer really depends on the battery and the tool. A smaller 2.0Ah battery on a 20V trimmer might give you 15-20 minutes of continuous use, which is fine for a quick touch-up. A larger 5.0Ah battery on a 40V or 56V model can often last 45 minutes to over an hour, which is enough for most medium to large yards. The type of vegetation you’re cutting also plays a big role; thick, wet grass will drain the battery much faster than dry grass.
Are battery powered trimmers as powerful as gas trimmers?
For the average homeowner, absolutely. Modern high-voltage battery trimmers have closed the power gap significantly. They have no problem handling grass, weeds, and even some light brush. While a commercial-grade gas trimmer might still have an edge for all-day, heavy-duty use on very thick overgrowth, the power of a top-tier battery model is more than sufficient for maintaining a beautiful yard without the noise, fumes, and maintenance.
Can I use the same battery for other tools from the same brand?
In most cases, yes, and this is one of the biggest advantages! Brands like Ryobi, DeWalt, Makita, and EGO design their batteries to be a universal platform. This means the battery that powers your string trimmer can also power that brand’s leaf blower, chainsaw, or drill. This interoperability saves you money and makes your tool collection much more convenient. Always double-check the battery compatibility for your specific brand and model.
What is the difference between a trimmer and an edger?
A string trimmer is primarily for cutting grass and weeds in places your lawn mower can’t reach, like along fences, walls, and around trees. It uses a rapidly spinning nylon string to do the cutting. An edger, on the other hand, is designed to create a clean, vertical cut along the edges of your lawn, like next to a sidewalk or driveway, giving it a sharp, manicured look. Some string trimmers have an edging function that lets you pivot the head to perform this task, which is a great 2-in-1 feature.
How do I know when it’s time to replace the trimmer line?
You’ll know it’s time to replace the line when it wears down enough that you can’t effectively cut your grass, even after bump-feeding or the automatic feed has advanced new line. The line slowly wears away from use. It’s a good idea to keep a spare spool of the correct size and type of line on hand so you can reload it as soon as you notice a drop in performance. Trying to use a trimmer with worn-out line is inefficient and can put extra strain on the motor.
