What does “stud terminal” mean?
Stud terminals are threaded posts that secure compatible battery cable connections with nuts, rather than the clamp connections used on standard automotive top posts.

This is a starting battery designed to deliver high current for engine starting. For applications requiring repeated discharge and recharge, see our Group 31 deep-cycle battery (31DC). Confirm that its specifications and terminal type suit your application.
