Odyssey PC925L Extreme AGM Battery – Powersport & Performance | Thin Plate Pure Lead (TPPL)

Power your performance vehicle, powersport application, or race car with the Odyssey PC925L Extreme AGM Battery — a Thin Plate Pure Lead (TPPL) AGM battery that delivers up to twice the power and three times the service life of conventional batteries. Odyssey’s AGM2 TPPL technology outperforms standard AGM and flooded (SLI) batteries in every critical metric: power density, fast-charge acceptance, shelf life, vibration resistance, and long-term value. For performance vehicles, powersport applications, and motorsport builds where battery reliability and power delivery are non-negotiable, the Odyssey PC925L is the definitive choice.

Key Features:

• Thin Plate Pure Lead (TPPL) technology — pure lead plates machined thinner than conventional lead-alloy plates, allowing more plates per cell for dramatically increased power density and surface area
• Up to 2x the power of conventional batteries — higher cranking amps and reserve capacity versus standard AGM and flooded batteries of comparable size
• Up to 3x the service life — TPPL construction and AGM design deliver significantly longer service life than conventional batteries under the same operating conditions
• AGM (Absorbed Glass Mat) design — sealed, maintenance-free, spill-proof construction for safe installation in any orientation
• Fast-charge acceptance — TPPL technology accepts charge faster than conventional batteries, recovering more quickly after deep discharge or high-demand use
• Exceptional shelf life — can be stored for up to 2 years without charging and still recover to full capacity — ideal for seasonal vehicles and race cars
• Vibration resistance — AGM construction and robust internal design withstand the extreme vibration of motorsport and powersport applications
• Maintenance-free — sealed AGM design requires no water addition or electrolyte maintenance

Performance Benefits:

• Thin Plate Pure Lead Power Density: Pure lead plates can be manufactured thinner than conventional lead-alloy plates without sacrificing structural integrity — allowing more plates to fit within the same battery case. More plates means more active material surface area, which translates directly to higher cranking amps, greater reserve capacity, and superior power density in a compact package
• 2x Cranking Power: The PC925L delivers up to twice the cranking power of a conventional battery of comparable size — ensuring reliable engine starts in cold Canadian winters, after extended storage, and in high-compression performance engines that demand more cranking current than a standard battery can provide
• 3x Service Life: TPPL construction significantly reduces the sulfation and plate degradation that limits conventional battery service life — delivering up to three times the cycle life of standard AGM or flooded batteries under the same operating conditions
• Fast Charge Recovery: TPPL batteries accept charge at a higher rate than conventional batteries — recovering more quickly after deep discharge events, high-demand starts, or extended periods without charging. Critical for race cars and vehicles with high electrical loads
• Exceptional Shelf Life: The PC925L can be stored for up to 2 years without charging and still recover to full capacity — a critical advantage for seasonal vehicles, track cars, and powersport applications that sit unused for extended periods
• Vibration Resistance: AGM construction immobilizes the electrolyte in glass mat separators, eliminating the sloshing and plate damage that vibration causes in flooded batteries — essential for motorsport and powersport applications where vibration levels far exceed those of normal road use

• High-compression performance engines that demand more cranking current than a standard battery can reliably provide
• Vehicles with high electrical loads — audio systems, data loggers, cooling fans, and other accessories that demand more from the battery

What’s Included:

• Odyssey PC925L Extreme AGM battery (ODS-AGM28)

Installation Notes:

• Verify battery dimensions and terminal type fit your application before installation
• Sealed AGM design — can be installed in any orientation including on its side
• Use a compatible AGM battery charger — do not use a conventional flooded battery charger set to a high charge rate, as this can damage AGM batteries
• If the battery has been in storage, charge fully before installation using an Odyssey-compatible charger
• Clean battery terminals and cable ends before installation to ensure a low-resistance connection
• Secure the battery firmly in its tray — vibration resistance is excellent, but proper mounting prevents movement that can stress cable connections

Thin Plate Pure Lead (TPPL) Technology – Why It Matters:

Conventional lead-acid batteries — both flooded and standard AGM — use lead-alloy plates. Lead alloys are used because pure lead is too soft to maintain structural integrity at conventional plate thicknesses. Odyssey’s TPPL technology solves this by manufacturing plates from 99.99% pure lead at a thickness that conventional alloy plates cannot achieve — thin enough to fit significantly more plates within the same battery case. More plates means more active material surface area in contact with the electrolyte, which directly increases the battery’s power output, charge acceptance rate, and cycle life. Pure lead also sulfates less aggressively than lead alloys during discharge and storage, contributing to the PC925L’s exceptional shelf life and cycle durability. The result is a battery that is genuinely superior to conventional AGM and flooded batteries in every performance metric — not just marketing claims.

AGM vs. Flooded Batteries for Performance Applications:

Absorbed Glass Mat (AGM) batteries immobilize the electrolyte in fibreglass mat separators between the plates, eliminating the free liquid electrolyte of flooded batteries. This design makes AGM batteries spill-proof and vibration-resistant — critical for motorsport and powersport applications where a flooded battery’s liquid electrolyte can spill, corrode, and damage surrounding components under the vibration and g-forces of performance use. AGM batteries also self-discharge more slowly than flooded batteries, making them better suited for seasonal and infrequent-use applications. Odyssey’s TPPL AGM design combines all the advantages of AGM construction with the superior power density and longevity of pure lead plates — the best of both technologies in a single battery.

Why Odyssey Battery?

Odyssey Battery (EnerSys) has been producing high-performance TPPL AGM batteries since the 1990s, with a product lineup trusted by military, aerospace, motorsport, and commercial applications worldwide. Their Extreme series batteries are the benchmark for performance AGM batteries — used by professional racing teams, powersport manufacturers, and performance enthusiasts who demand the highest level of battery performance and reliability. Odyssey’s TPPL technology is proprietary and patented — not replicated by conventional AGM battery manufacturers.

Perfect For:

• Performance street and track vehicles requiring maximum cranking power and long-term reliability
• Race cars and track day vehicles where battery weight, vibration resistance, and reliable starting are critical
• Powersport applications — motorcycles, ATVs, snowmobiles, and personal watercraft
• Seasonal vehicles and track cars stored for extended periods — up to 2 years shelf life without charging
• High-compression engines and vehicles with high electrical loads that demand more than a conventional battery can provide
• Anyone who wants Odyssey’s proven TPPL technology and 2x power / 3x life advantage over conventional batteries

Pro Tip: Use an Odyssey-compatible AGM charger (such as the Odyssey Battery Charger/Maintainer) for charging and long-term storage maintenance. A quality AGM charger with a maintenance/float mode will keep the PC925L at full capacity during storage without overcharging — maximizing the battery’s service life and ensuring it’s ready to start your vehicle after months of storage.

Note: Verify battery dimensions and terminal configuration fit your specific application before ordering. Use only AGM-compatible chargers — conventional high-rate chargers can damage AGM batteries.
