The ODYSSEY Extreme ODX-AGM34R is a BCI Group 34R Thin Plate Pure Lead (TPPL) AGM battery for working vehicles whose loads never fully shut off: emergency vehicles, 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.

If you are looking for a Group 34R battery around 850 CCA and 68 Ah (20-hour) with 135 minutes of reserve capacity, the ODX-AGM34R is the current version of the legacy 34R-PC1500 part number.

Small loads add up: per EnerSys parasitic-draw guidance and TMC RP140A, a combined 5-amp draw over a 60-hour weekend equals a 300 Ah discharge. A weekend sit has little impact, but a week of continuous draw can pull a battery below 10.5 volts, and if that happens routinely, performance and life are impacted. The ODX-AGM34R is built for exactly that duty: the highest cranking output in the WCB Group 34R lineup, deep-discharge recovery, extreme vibration resistance, fast recharge, and up to 400 cycles at 80% depth of discharge per EnerSys published ratings.

For emergency vehicles, mission-critical uptime, and vehicles that cannot afford a no-start, ODYSSEY Extreme is the floor — for daily drivers with stock electrical loads, the ODP-AGM34R covers the same Group 34R footprint. The ODX-AGM34R is an automotive and commercial battery and is not positioned for powersport applications.
