How long do the batteries last on a cordless snow blower?

Reported runtimes vary widely by model and snow type. Owners of EGO's 21-inch dual-battery blowers commonly report around 45 minutes on a charge, while smaller snow shovels often run 30-40 minutes. Across reviewers, the recurring advice is to budget for a second set of batteries if you have a large driveway, since cold weather and wet snow both shorten runtime.
