Review: Rechargeable battery for lawn mower - This was a secondary back up for a mower I already have. Helps me finish mowing the yard in one day. Very helpful to have. Recommend. Review: The new battery works ..."like a champ"! - This new battery is working great; probably 30-40 minutes on one charge, not using the self-propelled feature. The battery we got with the mower started limping in the 3rd year. We can still use it in this its 4th year, but it only charges 4 lights worth and gives about 10-15 minutes on a charge. However you measure it, the battery is well worth the price, to avoid using gasoline. ## Features - validated_bullets1 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083W6M5MS | | Batteries | 1 Lithium Ion batteries required.
