The 2020 Honda Passport uses a standard 12-volt automotive battery, and the typical replacement size is Group Size 35. When shopping for a replacement, look for a battery with about 550–650 cold-cranking amps (CCA) and roughly 100–120 minutes of reserve capacity (RC). Always verify against your vehicle’s current battery label or the owner's manual, since regional differences can occur.
Battery size and specs you should know
To replace the Passport battery correctly, you should match the group size, CCA, RC, and terminal layout. The most common replacement is Group Size 35, though some markets or trims may use an alternative such as Group 51R. The Passport relies on a 12V lead-acid battery; depending on climate and usage, owners sometimes opt for an AGM (absorbed glass mat) battery for enhanced durability and performance.
The following quick reference summarizes the typical specs you’ll want to mirror when selecting a replacement:
- Group size: 35 (primary option)
- Alternative/region-specific: 51R may be used on certain trims or markets
- Battery type: Flooded lead-acid (maintenance-free); AGM options available for harsh climates or high electrical loads
- Recommended CCA: approximately 550–650 CCA
- Reserve Capacity (RC): around 100–120 minutes
Bottom line: choose a battery with the same group size and at least the OEM’s CCA rating, ensure it fits the battery tray and terminal layout, and consider AGM if you want extra reliability in extreme conditions or with heavy electronics.
Summary
For a 2020 Honda Passport, the standard replacement battery is a 12-volt battery in Group Size 35, with roughly 550–650 CCA and about 100–120 minutes RC. Always verify the exact specifications on your current battery or via the owner's manual to account for regional or trim-based differences. If in doubt, consult a dealership or trusted parts retailer to confirm VIN-specific requirements and fitment.
