Check use & requirements

Check use requirements

Check NOCO’s current jump-starting instructions and the vehicle manual. These models are specified for 12V lead-acid starting batteries; an internal lithium battery does not mean lithium vehicle batteries are supported. No vehicle application or successful-start guarantee is established here.
