FullRiver FT840-24F AGM Battery

The FullRiver FT840-24F is a 12-volt AGM vehicle battery built for demanding starting and reserve-power needs. It uses a BCI Group 24F case and factory-activated construction for direct replacement applications that call for this size and terminal layout.

• 12-volt AGM battery with BCI Group Size 24F
• 840 cold cranking amps and 1050 cranking amps for strong starting output
• 65 amp-hour capacity at 5 hours and 79 amp-hours at 20 hours
• 163-minute reserve capacity at 25 amp load
• SAE Type A terminals with positive terminal on the top right
• Factory activated and equipped with a handle

Built for High-Demand Starting

FullRiver’s Full Throttle Series is engineered for vehicles that place steady demands on the battery. High-compression cells, a heavy-duty case, pure-lead cells, and thin-plate technology work together to deliver consistent power and resistance to shock and vibration. The FT840-24F is an AGM replacement battery for applications that require Group 24F fitment, including many Toyota 4Runner, Toyota Tacoma, and Lexus GX460 applications. This part number is FT840-24F.

This part cross-references Odyssey Battery (e.g., ODX-AGM24F) for the same application.

Common Problems It Can Address

• Slow engine cranking from a weak or aging battery
• Reduced reserve power during accessory use or repeated starts
• Battery performance loss caused by vibration and shock exposure
• Fitment issues when replacing a Group 24F battery with the correct terminal layout
• Starting concerns in vehicles that specify a 24F battery size

Installation Notes

Verify BCI Group 24F fitment, terminal orientation, and clearance before installation. Some listed applications note engine-compartment placement or vehicle-specific battery reset procedures, including certain Lexus RX350 applications. Confirm the vehicle’s required battery rating and venting setup before replacing the original unit. The FT840-24F part number should be matched to the vehicle’s battery tray and terminal configuration.

Quality Assurance

FullRiver’s AGM construction uses pure-lead cells and a heavy-duty case to support reliable starting performance and vibration resistance. The FT840-24F is factory activated and built as a replacement battery for demanding automotive and marine/RV starting applications.
