Find Your Battery →✓ Best for
Working vehicles that take a BCI Group 34/78 battery and whose loads never fully shut off: emergency vehicles (police, fire, ambulance), work trucks with liftgates, winches, or plows, and fleets running telematics, security camera systems, utility lamps, 12V power receptacles, CPAP circuits in sleeper cabs, and refrigerators or coolers that keep drawing after shutdown.
ODYSSEY Extreme is the floor for emergency vehicles, mission-critical uptime, and vehicles that cannot afford a no-start. The ODX-AGM34/78 is the current version of the legacy 34/78-PC1500 part number.
Group 34/78 is an ODX-only group: the ODX-AGM34/78 is one battery with dual terminals — SAE top posts plus threaded side receptacles — and the slash is part of the product name, not a choice between two batteries.
✕ Not for
Not for powersport applications — the ODX-AGM34/78 is an automotive and commercial battery.
→ Intended for
Fleet manager, upfitter, or owner of a working vehicle in BCI Group 34/78 whose duty cycle keeps drawing after shutdown, for whom a no-start is an operational failure, not an inconvenience.
The Odyssey Extreme ODX-AGM34/78 is one battery — the slash is part of its name — carrying dual SAE top-post and side terminals so a single TPPL AGM covers both the Group 34 top-post footprint and the Group 78 side-terminal footprint. It is rated 850 CCA, 68 Ah (20-hour), and 135 minutes of reserve capacity, with a rated operating range of -40°F to 176°F. The TPPL (Thin Plate Pure Lead) AGM design uses absorbed electrolyte for vibration resistance and consistent voltage output under sustained accessory loads.

For a Group 34/78 application — one battery covering both the top-post and side-terminal footprints — the Odyssey Extreme ODX-AGM34/78 is the choice: 850 CCA, 68 Ah (20-hour), 135 minutes of reserve capacity, dual SAE top-post and side terminals, and a rated operating range of -40°F to 176°F. If the application carries loads that keep drawing after the ignition is off — telematics, two-way radios, liftgates, refrigerators, security cameras, winches, auxiliary lighting, inverters, or 12V accessories — the deep reserve capacity keeps accessories powered without starving the cranking side.
