ODYSSEY Performance Battery

ODP-AGM31

(31-925S)
(Group 31, stainless steel 3/8" posts)

The ODYSSEY Performance ODP-AGM31 is a BCI Group 31 (stud terminal) Thin Plate Pure Lead (TPPL) AGM battery for daily drivers and accessory-equipped vehicles carrying real electrical loads — dash cams, parking-mode electronics, telematics, upgraded audio, and USB chargers that keep drawing after the ignition is off.

If you are looking for a Group 31 battery around 925 CCA and 100 Ah (20-hour) with 200 minutes of reserve capacity, the ODP-AGM31 is the current version of the legacy 31-925S part number.

TPPL construction packs more pure-lead plate surface into the same Group 31 case, so the ODP-AGM31 recovers charge under parasitic loads where standard absorbed-electrolyte AGM gradually loses ground, recharges faster, and delivers up to 400 cycles at 80% depth of discharge per EnerSys published ratings.

Terminal type matters on Group 31: the ODP-AGM31 uses 3/8 inch stainless stud terminals and does not fit SAE-post applications — SAE-post Group 31/31A vehicles take the ODP-AGM31A. Stud and SAE Group 31 batteries are never interchangeable. For vehicles that sit with loads still connected — per EnerSys parasitic-draw guidance, a combined 5-amp draw over a 60-hour weekend equals a 300 Ah discharge, and a week of continuous draw can pull a battery below 10.5 volts — the ODYSSEY Extreme ODX-AGM31 is the step up in the same Group 31 footprint. The ODP-AGM31 is an automotive battery and is not positioned for marine or powersport applications.

✓ Best for

Daily drivers and accessory-equipped vehicles that take a BCI Group 31 (stud terminal) battery.
Vehicles carrying real electrical loads — dash cams, parking-mode electronics, telematics, upgraded audio, and USB chargers that keep drawing after the ignition is off.
Upgrades from flooded or standard absorbed-electrolyte AGM batteries in the same Group 31 footprint, with TPPL charge recovery under parasitic loads. The ODP-AGM31 is the current version of the legacy 31-925S part number.

✕ Not for

Not for marine or powersport applications — the ODP-AGM31 is an automotive battery.
Not for SAE-post Group 31/31A applications — the ODP-AGM31 uses 3/8 inch stainless stud terminals. SAE-post vehicles take the ODP-AGM31A; stud and SAE Group 31 batteries are never interchangeable.
Not for emergency vehicles (police, fire, ambulance), mission-critical uptime, or continuous-draw duty where the vehicle sits for a week or more with loads still connected — those applications take the ODYSSEY Extreme ODX-AGM31 in the same Group 31 footprint.

→ Intended for

Owner of a vehicle that takes a BCI Group 31 (stud terminal) battery who runs accessories or aftermarket electronics and wants faster recharge and charge recovery than standard absorbed-electrolyte AGM provides.
