The Neuton Mower's unique removable battery lets you simply lift out the battery, drop in a freshly charged one, and start mowing again in seconds. Many mowers do not have removable batteries—you'd have to wait for hours to recharge an onboard battery before mowing again.
The 24-Volt Spare Battery works with the new Neuton CE5 Mower. It is also compatible with the DR® WhisperLite Battery-Powered Mower and the Neuton EM 4.1 and earlier (pre-2006) models.
