SuperCharge MFM70 SeaMaster Gold 12V 750CCA Marine Battery

Quick answer

The SuperCharge MFM70 is a 12V N70 size marine starting battery from the SeaMaster range, rated at 750 CCA and 85Ah at the 20 hour rate.

Dual system terminals take either automotive posts or stud connections, which helps when a boat has ring terminal leads.

Problems it solves

• Outboards that are slow to turn over. 750 CCA gives a strong start.
• Ring terminal leads on a boat. Dual system terminals accept studs as well as posts.
