I currently have three B&D power tools that are run by 18volt batteries. I bought two new batteries recently and when fully charged, they lasted approximately 15 minutes. I have heard that with an adapter I could use a lithium 20volt with these tools instead of getting brand new ones. The model numbers of the three tools are NSW18 leaf blower, NST2018 Type 2 Grass Hog, and NHT2218 Type 1 hedge trimmer. I would appreciate some advice.
Lithium batteries cost enough purchased alone when you can often just as easily buy them included in kits with brand new tools. Not that I am huge on sounding like a paid ad but if this is just for personal/home use I would check the Ryobi Days sales going on at Home Depot here:

If you are a really diligent type about your lawn though you may still find upscale brands to last longer, have better efficiency, and better ergonomics though.
