I have the Dewalt 60v Stringtrimmer ( the "17" model that accepts attachments). I live on a 200 acre resort in the mountains of Northern California. We have a fairly large Facilities Dept. where we have 3 Stihl weedwhackers, a twin handled four stroke Honda, and 2 Shindawa's. The Dewalt will keep up with any of these except the Honda (it's a beast). Where it falls short is on run time, any of our gas weedeaters will run for 45 mins. on a tank of gas. The Dewalt will drain two 9ah batteries in the same length of time. So....we own four (4) of the 9AH batteries which give us a total of about an hour and a half of run time. That's pricey.

The deal is...we think it's worth it... because of how much quiter the Dewalt is it creates much less disturbance in areas near where guests are staying, it's still noisy but not nearly as noisy as the gas weed whackers.

I haven't had these batteries operating long enough to know what kind of longevity they will have. I do know that they often have to cool down after using them before they can be recharged. This can take an hour to an hour and a half of cooling time before they are charged which requires another hour on a 60v speed charger. With roughly $1000 worth of batteries to run a weedwhacker, we need these batteries to last awhile. I hope that they do.

Very expensive. $150.00, but still the least expensive of all the marketplaces. Just used it last night and it held a charge the entire time.

I own many dewalt power tools. 15 at least and many batteries. Best part about this company is the warranty. They sure do stand behind their products. Had an issue with wood saw once. Dewalt instructed me to send in the defective product. This was out of warranty BTW. Next thing I know they’re sending me a brand new saw with a brand new battery. This company is amazing like Amazon.
Thanks Dewalt!
