#1 · Best Overall

1. Interstate 31-AGM5

• Weight: 60 lb
• Voltage: 12 V
• Compatible with Vehicle Type: Boat

Best for: Accessory-heavy marine power.

Why it ranks #1: Its 12V, 100Ah AGM combines 925 CCA with listed support for a boat motor, trolling motor, and accessories, making it a versatile bass-boat fit.

Interstate’s 100Ah pure-lead AGM combines high-cranking output with deep-cycle power, enabling a single Group 31 battery to run a boat motor and accessories over extended periods.
