The ODYSSEY ODX-AGM34 battery is a Group 34 AGM replacement rated at 850 CCA, with 68 Ah at the 20-hour rate and 135 minutes of reserve capacity. ODYSSEY identifies it with the legacy 34-PC1500 name. Choose it only when the dimensions, top-terminal layout and charging requirements match your vehicle.
Top Picks
Top Pick: Odyssey 34-PC / ODX-AGM34
This Group 34 AGM battery is best suited to buyers who need strong starting performance, useful reserve capacity, and deep-cycle capability in a vehicle that is compatible with its physical size and terminal configuration.
Best For: Compatible cars, trucks, SUVs, recreational vehicles, and other applications with demanding electrical loads.
Main Limitation: At about 49.5 pounds, it is relatively heavy, and Group 34 sizing alone does not guarantee correct fitment.
Selection Criteria
This guide focuses on a single battery rather than presenting an artificial multi-product ranking. The most important buying factors are:
- Correct fitment: Battery dimensions, tray size, hold-down system, terminal position, and cable reach must match your vehicle.
- Starting power: Cold cranking amps should meet or exceed the requirements specified by the vehicle manufacturer.
- Reserve capacity: Higher reserve capacity can be useful in vehicles with substantial electrical demand.
- Battery construction: AGM construction can suit applications where vibration resistance, sealed operation, and cycling performance are priorities.
- Weight and installation: A heavier premium battery may be less convenient to handle during installation.
Odyssey 34-PC

Why You’ll Like It
- Strong starting output: Its 850 CCA rating makes it suitable for demanding applications when that output matches the vehicle’s requirements.
- Useful reserve capacity: A 135-minute reserve-capacity rating can benefit vehicles carrying substantial electrical loads.
- Dual-purpose capability: The design is intended to provide both starting power and cycling capability rather than functioning only as a basic starter battery.
- Standard Group 34 format: It can fit a variety of applications designed around this battery group, provided dimensions and terminal orientation are compatible.
Things to Consider
- Its roughly 49.5-pound weight makes installation more demanding than with many lighter batteries.
- A Group 34 designation does not by itself guarantee correct fitment for every vehicle.
- Premium AGM batteries may cost more upfront than conventional flooded lead-acid alternatives.
- Your vehicle’s charging system should be appropriate for the battery type and manufacturer requirements.
Who Should Buy This?
Consider the Odyssey 34-PC if your vehicle is compatible with its Group 34 dimensions and terminal layout and you want substantial starting output combined with reserve and cycling capability. It may be especially attractive for vehicles running additional electronics or accessories, provided the battery meets the vehicle manufacturer’s requirements.
Who Should Avoid This?
Choose another battery if your vehicle requires a different group size, reversed terminal layout, different physical dimensions, or another battery specification. It may also be unnecessary if your vehicle has modest electrical requirements and a less expensive battery already satisfies every manufacturer requirement.
Before You Buy
- Confirm that your vehicle accepts a Group 34 battery.
- Compare the battery’s dimensions with the available battery tray space.
- Check positive and negative terminal orientation and cable reach.
- Confirm that 850 CCA meets your vehicle manufacturer’s specification.
- Verify the required hold-down hardware.
- Check your vehicle manual for battery type and charging-system requirements.
- Review current warranty, seller, shipping, and return information before ordering.

ODYSSEY ODX-AGM34 battery: model checks
ODYSSEY’s exact model page confirms the specifications in this guide, including the SAE top terminals, 10.9 × 6.8 × 7.9-inch dimensions and 49.5-pound weight. The height includes the terminals. Its 1,500 five-second pulse rating is not the 850 CCA rating.
This article covers the ODYSSEY model already linked here rather than claiming one battery brand is best for all vehicles. For seller selection and other battery types, see our car-battery buying guide. A Group 34R or 34/78 version has a different terminal arrangement; confirm the actual delivered model.
Installation and handling
- Check the owner’s manual for the required chemistry, size, venting, electrical rating and battery-registration procedure.
- Have a qualified installer handle inaccessible mounting, coding or high-voltage vehicle precautions. Keep sparks and flames away and wear suitable eye and hand protection.
- Follow the vehicle’s disconnect/reconnect sequence and ODYSSEY’s mounting and charging instructions. Secure the hold-down and avoid bridging terminals with a tool.
- Return the old lead-acid battery to a retailer or approved battery collection program.
Reserve minutes are a rating measured at a specified load; they are not a promise that accessories will run for that long. Check current seller warranty and return terms separately.
FAQ
Is the Odyssey 34-PC an AGM battery?
Yes. The current Odyssey model associated with this Group 34 product is designated ODX-AGM34.
How many cold cranking amps does the Odyssey 34-PC provide?

Odyssey lists a reserve capacity of 135 minutes for the ODX-AGM34.
Will the Odyssey 34-PC fit every vehicle that uses a Group 34 battery?
Not necessarily. Group size is an important starting point, but you should also confirm dimensions, terminal orientation, cable reach, hold-down design, and the electrical requirements specified by your vehicle manufacturer.
Is this battery suitable for vehicles with extra accessories?
It can be a strong candidate for compatible vehicles with meaningful electrical demands because it combines substantial starting output with reserve and cycling capability. However, accessory load, alternator output, wiring, and the vehicle manufacturer’s battery requirements should all be considered.
What should I check before ordering?
Confirm group size, physical dimensions, terminal arrangement, required CCA, battery type, charging compatibility, and the seller’s current warranty and return terms.
Wrapping Up
The Odyssey 34-PC, represented by the current ODX-AGM34 Group 34 model, is a strong option for buyers who need substantial starting power, reserve capacity, and cycling capability in a compatible vehicle. Its 850 CCA rating and 135-minute reserve capacity are notable specifications, but fitment should always come first.
Before purchasing, compare the battery’s dimensions, terminal position, electrical specifications, and charging requirements with your vehicle manufacturer’s recommendations. If everything matches, the Odyssey is a compelling premium Group 34 AGM option.
Buy the Odyssey 34-PC only after confirming exact fitment and electrical compatibility. It makes the most sense for buyers who can benefit from its starting output and reserve capability rather than shoppers simply looking for the lowest-cost replacement battery.
