Fullriver DC400-6 6V 415Ah Deep Cycle AGM Battery

The Fullriver DC400-6 6V 415Ah Deep Cycle AGM Battery delivers dependable energy storage for solar battery banks, off-grid power systems, and demanding deep-cycle applications. Built with sealed Absorbent Glass Mat (AGM) technology, the DC400-6 provides high-capacity energy storage without the routine watering required by traditional flooded lead-acid batteries.

Rated at 415 amp-hours at the 20-hour discharge rate, this 6-volt battery provides approximately 2.49kWh of nominal stored energy. Its L16/903 case design makes it suitable for compatible battery enclosures and multi-battery storage configurations.

The DC400-6 uses a sealed, non-spillable AGM construction with a fiberglass separator that absorbs the electrolyte. Its deep-cycle design is intended for applications requiring repeated charging and discharging.

For homeowners, solar installers, and off-grid system builders seeking a high-capacity AGM solar battery, the Fullriver DC400-6 offers a maintenance-free alternative to conventional flooded deep-cycle batteries.

High-Capacity AGM Battery for Solar Energy Storage

The Fullriver DC400-6 is suitable for appropriately designed solar battery banks that require dependable deep-cycle energy storage.

Its 415Ah capacity at the 20-hour discharge rate makes it a practical option for systems that store solar electricity for later use, including off-grid applications and compatible backup power configurations.

Unlike flooded lead-acid batteries, AGM batteries use absorbed electrolyte and sealed construction, reducing routine maintenance requirements.

For larger energy storage systems, multiple DC400-6 batteries can be connected in series to achieve the required battery bank voltage, provided the configuration is compatible with the charging equipment and system design.

Deep Cycle Performance Across Multiple Discharge Rates

Battery capacity varies depending on how quickly energy is discharged. The Fullriver DC400-6 has published capacity ratings across several discharge durations.

• 100-Hour Rate: 460Ah.
• 20-Hour Rate: 415Ah.
• 10-Hour Rate: 374Ah.
• 5-Hour Rate: 340Ah.

The 20-hour rating of 415Ah is the standard capacity reference used for this product listing.

Actual usable energy depends on discharge rate, operating temperature, depth of discharge, battery condition, and the connected electrical system.

Maintenance-Free Sealed AGM Construction

The DC400-6 uses Absorbent Glass Mat technology, in which the electrolyte is retained within fiberglass separators.

This sealed battery construction provides a non-spillable design and eliminates the routine water additions associated with flooded lead-acid batteries.

The battery uses an ABS plastic case and a DTW dual AP and stud terminal configuration.

Its L16/903 case size measures approximately 11.61 inches long, 7.05 inches wide, and 16.69 inches tall including terminals.

Solar Battery Bank Configurations

The Fullriver DC400-6 can be used in appropriately designed battery banks requiring higher nominal system voltages.

• 12V Battery Bank: Two 6V batteries connected in series provide 12V nominal at 415Ah.
• 24V Battery Bank: Four 6V batteries connected in series provide 24V nominal at 415Ah.
• 48V Battery Bank: Eight 6V batteries connected in series provide 48V nominal at 415Ah.

These examples describe nominal series-connected battery configurations. Usable capacity, charging requirements, and compatibility depend on the complete system design.

Applications

• Off-grid solar energy storage.
• Residential solar battery banks.
• Compatible backup power systems.
• Renewable energy storage applications.
• Deep-cycle battery bank replacements.
• Other compatible high-capacity AGM battery applications.
