Interstate Batteries M-47/H5 Flooded Battery

The M-47/H5 is a BCI Group 47 (H5) battery. The manufacturer lists over 500 year, make, and model applications for this group size. Confirmed applications in the CCT vehicle-fitment index include the current-generation Honda CR-V's gas engine trims (LX, EX, EX-L), the Acura Integra and NSX, the Chevrolet Sonic and first-generation Volt, and the Toyota C-HR, Sienna, and Venza. Always confirm your specific year and trim against the manufacturer's fitment guide before purchase.

Not exactly. Honda's genuine OEM battery for 2023 to 2026 CR-V gas trims is an H5EFB, an Enhanced Flooded Battery built for the CR-V's Idle Stop system. The M-47/H5 is a conventional flooded battery in the same BCI group and case size. Independent guidance describes standard flooded as an acceptable substitute on CR-V idle-stop trims, though not the exact chemistry Honda specifies.

The M-47/H5 is Interstate's value-tier line for Group H5. Interstate also sells an MT-47/H5 (mid-tier flooded, 650 CCA, 24-month warranty) and an MTX-47/H5 AGM battery in the same case size, both positioned above this conventional flooded model. All three share the Group H5 footprint but use different internal chemistry or construction and carry different warranty terms.

Yes. It's confirmed on both the Amazon listing and Interstate's own official Battery Application Guide, the dealer spec sheet used to certify BCI group and cranking-amp ratings. Interstate's consumer website separately lists 525 CCA for this exact battery, which does not match either of the other two sources and appears to be a content error on the website rather than the real spec.

The product label shows a sealed dome-style top with no user-accessible screw caps, and the manufacturer does not publish water top-off instructions, consistent with a sealed maintenance-free flooded design.
