(1) - 36V Lead-Acid Mower Battery

This battery (WA3229) is compatible with the WG770 mower.

The 36V lead acid battery weighs about 32 lbs.

On the WG770 mower, each 36V lead acid battery will provide enough working time per charge to cut up to 10,820 sq ft. Actual results may vary depending on the density of the grass or weeds you’re cutting, the amount of trimming versus edging, and the age of the battery pack.

Our lithium batteries and lead acid batteries are separate platforms and are not interchangeable.

Regardless of the tool or job at hand, we recommend that our customers follow standard safety precautions while using our tools, including wearing safety eyewear, gloves, appropriate shoes and clothing, and keeping hair tied back. Always refer to the owner’s manual for complete safety information before operating any tool.

If you decide this battery isn’t right for you, we offer a 30-day Money Back Guarantee from the date of receipt (less shipping and handling).  View more information here.
