Yes, you can generally leave the batteries in the mower between regular cuts. However, there are a few things to keep in mind to protect the battery life:

Extreme Temperatures: If your shed or garage gets very hot in the summer or freezing in the winter, it is better to take the batteries indoors.

Long Gaps: If you aren't planning to mow for several weeks (or during the winter), you should definitely remove them and store them in a cool, dry place at about 50-80% charge.

Safety Key: If your mower has a removable safety key, it’s a good habit to pull it out between mows to prevent any slow "parasitic" battery drain and for added safety. Mark
