Super Long Life Batteries

Purchased two 8Ah batteries to use with my 21" Nitro Self Propelled 40V Mower. I couldn't be happier with them. I have a third acre lot and had to change batteries before finishing. Not anymore though. I still have power left over to use with the string trimmer, edger, and 40V nitro Worx blower. All I can say is if your changing batteries or waiting for them to charge up again to finish the job, then get these batteries. You will thank yourself later.

The extra power it provides and the longevity is well worth it! It really jazzed up my worx tools and is now my go to battery when I need performance.

I have many Worx tools. Bought many for gifts. Ilike that when I run out of battery I can go pick up , either from another tool, or an extra and finish what I was doing. The table saw is great for an amateur wood worker like me. The Hydro wash, leaf blower edger, saw.....Love them all!!!
