The ODP-AGM94R H7 L4 is Odyssey's Performance Series 12-volt AGM battery, listed by the manufacturer as the current number for the legacy 94R-850 (LN4-H7) and built with SAE posts. The manufacturer positions the line for vehicles that run heavy onboard electronics, promising long service life, high reliability, and deep-cycle capability, while leaving out the higher cranking and reserve figures of the brand's Extreme line for buyers who do not need them. For a truck or performance car with a large accessory load, that trade-off can justify the price over a standard flooded battery.
Stepping up from a conventional battery means more cold-start margin: this unit is rated at 850 cold cranking amps, 1500 amps pulse (5-second) cranking, and a 155-minute reserve capacity, so the electrical system keeps running longer when the engine is off. The manufacturer's recommended minimum charging current is 7.6 A, which matters if you run a smart charger or a dual-battery setup. Before ordering, confirm the Group 94R (H7/L4) size against your vehicle's application guide, because fitment lists vary across sellers. Long-tail searches like "94R-850 AGM battery upgrade," "H7 LN4 850 CCA AGM replacement," and "Group 94R AGM battery for heavy accessory loads" describe this part's real use case.
Yes. The manufacturer lists ODP-AGM94R H7 L4 as the current part number for the legacy 94R-850 designation, which it also shows as LN4-H7.
The manufacturer specifies SAE posts, so use SAE-style clamps and hardware that match those posts.
The manufacturer rates operation from -40°F to 140°F and recommends storing the battery near 68°F.
The manufacturer lists a recommended minimum charging current of 7.6 A, so match your charger settings to that figure.
This is a bolt-in replacement for a Group 94R battery, so most owners can handle it with basic hand tools and a wrench for the hold-down and clamps. At roughly 55 lb, lift it with a helper or a strap and keep it level. Before you disconnect anything, note which post is positive and which is negative, and check that the cables reach the new battery's posts without strain, because terminal placement is described inconsistently across sources. Always disconnect the negative cable first and reconnect it last. The manufacturer does not publish a terminal torque value, so tighten the clamps snugly without overtightening the SAE posts, and confirm the hold-down is secure, since vibration resistance is one of the reasons to choose an AGM design.
