What’s the battery length with the mower?

My need is no more than 30 minutes. When finished there are still 3 lights lit up on battery. I’ve then switched battery to hedge trimmer and used for additional 39 minutes with still plenty of charge left.

Yes, the battery lasts enough to cut about 5,000 square feet without shutting down.
