The 2019 Chrysler Pacifica uses a standard 12-volt auxiliary battery for vehicle electronics; most units use a 12V AGM battery in the 70–75 Ah range with roughly 700–750 cold-cranking amps, though exact size can vary by trim and whether the vehicle is gasoline or hybrid.
In the Pacifica lineup, there are two powertrain setups: gasoline-powered and the Pacifica Hybrid plug-in. Both rely on a separate high-voltage battery for propulsion, while the 12V auxiliary battery handles starting and electronics. Replacement parts should match the original specifications to avoid electrical issues.
Core specs you should know
Gasoline vs Hybrid considerations
Common specs you might encounter when shopping for or replacing the auxiliary battery include the following:
- Group size: Typically Group 48 (also called H6) for many FCA 12V batteries, though exact size can vary by trim; always verify on the battery label.
- Battery type: Absorbent Glass Mat (AGM) lead-acid is common in modern Pacificas.
- Capacity (Ah): About 70–75 amp-hours.
- Cold-cranking amps (CCA): Roughly 700–750 CCA.
- Location and orientation: Mounted in the engine bay; the battery is accessible for replacement and service.
Note: Exact group size and capacity can vary by region or model year; always confirm with the battery label or the owner's manual.
How to confirm the exact battery for your vehicle
To confirm the exact auxiliary battery size for your specific Pacifica, follow these steps:
- Check the battery label in the engine bay for the group size (e.g., 48/H6) and CCA rating.
- Consult the owner’s manual or the official Chrysler service information for your trim and region.
- If you have a Pacifica Hybrid, remember the 12V battery is separate from the high-voltage propulsion pack; confirm you’re replacing the 12V unit.
- When purchasing a replacement, choose the OEM or an equivalent 12V AGM battery that matches the group size and CCA.
Following these steps will help ensure you select the correct 12V auxiliary battery for your Pacifica.
Summary
The 2019 Chrysler Pacifica relies on a standard 12-volt auxiliary battery for starting and electronics. While many units use an AGM battery around 70–75 Ah with about 700–750 CCA, exact specifications depend on trim and powertrain. The Hybrid has a separate high-voltage pack for propulsion, but the 12V system is still required for accessories. Always verify via the battery label or dealer to ensure an exact match.
