If your Sea Doo Seascooter is not charging up or is suffering from poor run times a new Sea Doo battery is your ticket to getting back up to speed. Restore your Seascooter's performance or pick up another battery as a spare for extended use. Proper maintenance is the key to a long life for water scooter batteries. Be sure to keep your Sea Doo Seascooter batteries charged when in storage and re-peak them once every three months. Storing a discharged battery is the number one cause of failure.
