otis24 Posted August 2, 2019 Report Share Posted August 2, 2019 Well, I screwed up! I purchased a Milwaukee M18 string trimmer. I ordered the bare tool thinking that I was saving money. Figured I could just use the batteries from my Milwaukee M18 drill and impact. Those batteries are 2.0 Ah, I think. Needless to say they last about 10 minutes at best in my string trimmer. It looks like the trimmer tool kit comes with a 9.0 Ah battery. Do I need a 9.0 Ah battery or can I get by with a smaller Ah battery (5.0 Ah, 6.0 Ah)?

trapper1306 Posted August 5, 2019 Report Share Posted August 5, 2019 A 5.0 regular battery on turtle mode usually has no problem doing roughly 7,500 square foot of grass on our property. The 2.0s on it are generally useless unless you have a really small yard. But the 5.0's definitely do the trick for most normal city yards I would say. Especially if you see no use for a 9.0 for yourself, you can purchase 2- 5.0s on ebay for the price of 1 9.0. A 9.0 or a 12.0 will give you a little more power and much more runtime. All depends how big of an area you need to do. Quote Link to comment Share on other sites More sharing options...
