Savior Products Junior battery trays combine universal-fit and ShockStop technology to prevent premature battery failure, generally caused by shock and vibration, of the most common smaller battery sizes. ShockStop mounts incorporated between the tray and bottom plate help absorb and dissipate shock and vibration to extend battery life. These durable composite trays secure your battery by utilizing a strap and buckle and incorporate FlowStop technology; a honeycomb base designed to prevent incidental battery acid spillage from running all over the tray or coming into contact with your hands while changing the battery out.
