Sealed lead acid (SLA) batteries are designed to cycle on a daily basis so they provide the highest level of battery life for demanding applications. This battery features 'non-spillable' construction which prevents the battery acid inside from spilling or leaking out and is virtually maintenance-free. Because this battery is non-spillable, it is classified as nonhazardous and can be taken on boats, trains, and planes. This battery can be used for most travel scooters and travel power wheelchairs.*We always recommend that you refer to your product Owner's Manual to ensure proper voltage and amperage before purchasing a replacement battery.
