- Two-Pack for 24V or Balanced Deep Cycle: Each 85Ah unit supports trolling motors and deep-cycle loads when used in pairs.
- Maintenance Free: No need to check electrolyte or add water.
- Versatile Mounting: 8mm terminals and standard Group 24 dimensions help compatibility.
Best for: Buyers planning a 24V trolling motor setup or scaling deep-cycle capacity with two batteries. Caution: Two-battery configurations require proper wiring and charging to maintain balance.
Buying Guide
What to consider when selecting a Group 24 AGM battery:
- Power needs: If you need engine starting power plus deep cycling, choose a dual-purpose AGM with high RC/CCA and good Ah. For only deep-cycle, a higher Ah rating is beneficial.
- Space and weight: Group 24 dimensions are standard; consider space in your boat or RV and weight limits.
- Vibration and mounting: Marine deployments benefit from vibration resistance; verify mounting orientation allowances from the manufacturer.
- Charging regimen: AGM batteries respond to specific voltage and current. Follow recommended charging parameters (e.g., 14.4V charge with current limits where stated) to maximize life.
- Maintenance: AGM is maintenance-free, but avoid extreme temperatures and keep terminals clean and tight.
- System compatibility: If combining with other batteries or solar, check series/parallel configurations supported by the pack.
