New Cordless Stihl Battery Systems

AK Stihl Battery System

As mentioned above, this is an all new battery series for Stihl. It’s out in Europe but is now finally coming to North America. It is a more compact line of batteries. It is still a 36V system but the batteries are much lighter. This series is designed for maintaining suburban yards. There are two battery capacities available, the AK-10 and AK-20. The series includes a hedge trimmer, blower, string trimmer, and chainsaw.

The two tools in this series that impressed us the most were the hedge trimmer and chainsaw. The hedge trimmer includes an all steel, double-sided, 18″ cutting head. The same construction as the gas powered units. It comes with the smaller capacity AK-10 battery and comes in at just 8.1 pounds. Despite the smaller capacity, it gives a continuous runtime of 40 minutes. That’s a long time for a battery unit. Long enough to cut 918′ of hedge top (18″ wide).

The other tool that impressed us was the MSA 120 C chainsaw. It has a 12″ bar with 1/4″ picco chain, brushless motor, and tool-less chain adjustment. It comes with the AK-20 battery which is good for 100 cuts in a 4″ log. It will be available in spring of 2017 for 299.95. This is a really impressive unit, cutting through 4-5 inch logs was quick, relatively effortless, and most of all quiet. I’ve used gas chainsaws all of my adult life and using a quiet saw is a strangely refreshing experience.

AI Stihl Battery System

Like the AK, the AI series is all new to Stihl. It is geared towards small urban or condo yards. It has an integrated 18V li-ion battery with an external charger. I know what your thinking, we’ve seen integrated OPE before and the batteries didn’t hold a charge and they quickly became boat anchors in only a year or two. What’s different about Stihl is that they service all of their own equipment at the independent dealer you bought it from. This includes the battery packs. There are three tools in this series, a trimmer, hedge trimmer, and blower and they all will retail for $129.95 in spring of 2017stihl battery -cordless-string-trimmer

The hedge trimmer and blower were of particular interest. Like the hedge trimmer in the AK line it also has an impressive 40 minutes of runtime but unlike the AK trimmer, this one is 3 pounds lighter at 5.1 pounds. That is really light.

The blower is also really light. It weighs in at 4.4 pounds. It boasts 10 minutes of runtime which doesn’t sound like much but it is capable of clearing 2,153 sqft. Perfect for a small yard.stihl battery -cordless-hedge-trimmer

Check Them Out For Yourself

It’s one thing to read about a tool online and then go out and buy it. Outdoor Power Equipment can be a different animal entirely. You want to go check it out locally to see how it feels in your hands and how it will fit into your workflow. Talk to the people that work on them to learn exactly how to care for it to get the most life out of the tool. This is where your local independent servicing dealer comes in. They have the knowledge to help you find equipment that best suits your needs. For a quick overview of all the tools before they are released, check out the image gallery below.

    We just purchased the new RMA510 lawn mower. It is so new that it does not appear on Stihl’s website. I was a bit reluctant to jump at such a new product but the Stihl name and my local dealer convinced me to jump. I gave it a test in the backyard and my initial response is – Wow! Looking forward to using this new Stihl mower. Lots of questions remain concerning usage time, battery life, etc. West Coast lawns in the spring are “heavy”. Looks like this mower will handle the lawn well.

    Will it do well on Zosia in my small back yard , St. Augustine in the front ?

      The best advice we can give you is to go talk to your local dealer. They’ll have local knowledge of the grasses in your area and the capabilities of the machine in them.

    Did you see a demo or use the cut-off saw? I’m a masonry contractor and was wondering how it worked on concrete blocks.

      We did not.
