got a 21 Inch 56-Volt Lithium-Ion Cordless Self Propelled Lawn Mower. Came with a 7.5 ah battery. Can a lower Ah batteries be used (2,4,5 ah etc.) be used? same size?, Just want one to ad about 1/2 hr run time if needed. $350 is a lot for an additional battery (smaller ah is cheaper)
All ego batteries work in all ego tools and chargers - fully interchangable. Timothy is correct - you will only get 10-15 minutes from a 2.5 in a mower. Best deal is to buy a kit that includes a tool and a battery. How does a new blower or string trimmer sound. How about a snow blower with 2 batteries.
