The Chrysler Pacifica uses two different batteries depending on the model: a standard 12‑volt lead‑acid battery for all non-hybrid models, and, in the plug‑in Pacifica Hybrid, a high‑voltage lithium‑ion battery pack that powers the electric drive and enables EV operation.
Two battery systems, two roles
While both are part of the same family, the 12‑volt battery handles starting the vehicle and supplying the 12‑volt electrical system, while the high‑voltage pack in the Hybrid stores and delivers energy for the electric motors and regenerative braking.
Gas-powered Pacifica: the standard 12-volt battery
All gasoline‑powered Pacifica models rely on a conventional 12‑volt battery to start the engine and run accessories such as the infotainment system, lights, and other electronics. Most vehicles use a lead‑acid battery; many modern Chrysler/Fiat designs also employ an AGM (absorbed glass mat) configuration for improved durability and cycling, but the battery remains a low‑voltage energy reservoir and is not used to drive the vehicle.
Pacifica Hybrid: the high‑voltage battery for propulsion
The plug‑in Pacifica Hybrid uses a high‑voltage lithium‑ion battery pack to power the electric motors and to allow electric‑only driving. For most model years, the pack capacity is about 16 kilowatt‑hours (kWh), with a nominal voltage in the 350–360‑volt range. The battery is sealed and maintenance‑free, and it is charged via plugging in or through regenerative braking when the gas engine runs.
Here are the key specifications for the Pacifica Hybrid’s high‑voltage battery:
- Capacity: nominal around 16 kWh (usable energy typically 13–14 kWh, depending on year and state of charge)
- Voltage: roughly 350–360 volts DC
- Chemistry: lithium‑ion (the pack uses a nickel manganese cobalt oxide formulation common to modern hybrids)
- Arrangement: integrated into the floor of the vehicle, powering the electric motors and providing EV mode capability
- Manufacturer: LG Chem (battery pack supplied by LG)
The electric‑only range, charging options, and integration with the gasoline engine can vary by model year, but owners generally experience a few dozen miles of EV range on a full charge, depending on driving conditions and climate. The on‑board systems coordinate the petrol engine and electric drive to optimize efficiency and performance.
Charging and range
Charging is available via household outlets or dedicated charging stations. On Level 1 charging (standard 120‑volt outlet), a full recharge can take roughly 11–13 hours, depending on the charger and state of charge. Level 2 charging (240 volts) typically reduces recharge time to about 2.5–3.5 hours, assuming a compatible Level 2 charger and the vehicle’s 6.6 kW onboard charger. EPA estimates for the Pacifica Hybrid place electric range around 32–33 miles on a full charge, with the total range expanded by the gasoline engine as needed.
Summary
In short, the Chrysler Pacifica uses a conventional 12‑volt battery for standard vehicle functions across all gas models, while the Hybrid uses a separate high‑voltage lithium‑ion battery pack for electric propulsion and EV operations. The two‑battery setup lets the Pacifica cover short daily trips on electricity and still rely on gasoline for longer journeys, with charging supported by household or public charging infrastructure.
