Jeep Wrangler 4xe Battery: Complete Guide
The Jeep Wrangler 4xe features a 17.3 kWh lithium-ion pack on a 400V system. This system delivers 21 miles of all-electric range. Pairing the battery with the 2.0-liter turbo gasoline engine pushes the total driving range to about 370 miles.
The 4xe produces 375 hp and 470 lb-ft of torque, while achieving 49 MPGe combined. It was America’s best-selling plug-in hybrid SUV, sold from 2021 to 2025 — Jeep dropped the 4xe for 2026, but the large owner base keeps its battery questions very much alive. The battery allows for quiet, all-electric trail driving and shares its core 17.3 kWh pack with the Jeep Grand Cherokee 4xe.
Quick answer
The Wrangler 4xe’s battery is a 17.3 kWh (about 15 kWh usable) NMC lithium-ion pack with 96 Samsung SDI cells, mounted under the rear seat. It gives 21 miles of EPA electric range and charges on AC only — there is no DC fast charging, and a Level 2 charge takes about 2 hours. The battery warranty runs 8 years/100,000 miles (10 years/150,000 miles in CARB states). Almost every Wrangler 4xe is also covered by a battery fire-risk recall: check your VIN, because completing that recall extends the battery warranty to lifetime coverage.

Why Does the Jeep Wrangler 4xe Have a Battery?
Better Off-Road Performance
The Wrangler has always been built for adventure. Adding a plug-in hybrid battery makes it even more capable. Unlike many hybrid SUVs that focus only on fuel savings, the Wrangler 4xe uses electric power to improve off-road driving.
The electric motor delivers instant torque, helping the vehicle climb rocks, crawl over rough terrain, and maintain better control at very low speeds.
Quiet Trail Driving
One of the biggest advantages of the battery is silent off-road driving. In Electric Mode, the Wrangler moves without engine noise, allowing drivers to enjoy nature while reducing noise pollution on trails.
Lower Daily Fuel Costs
Many people drive less than 21 miles per day. For those drivers, the Wrangler 4xe can complete most daily trips using electricity alone. Charging at home instead of filling the fuel tank every day can significantly reduce fuel costs.
eSave Mode
The Wrangler 4xe includes an exclusive eSave Mode. Instead of using battery power on the highway, the system saves it for later.
For example, drivers can travel long highway distances using the gasoline engine and arrive at the trail with a nearly full battery. They can then switch to Electric Mode and enjoy quiet off-road driving where electric power is most useful.
Three Driving Modes Explained
Hybrid Mode
Hybrid Mode automatically combines the gasoline engine and electric motor for the best balance between performance and efficiency. It is the default driving mode and works well for everyday driving.
Electric Mode
Electric Mode uses only the battery until the available charge is depleted. It is ideal for:
- Daily commuting
- Residential neighborhoods
- Parking garages
- Off-road trails
- Short city trips
eSave Mode
eSave Mode keeps the battery charged by relying mainly on the gasoline engine. It is useful during highway travel when drivers want to save battery power for later.
Jeep Wrangler 4xe Battery and Off-Road Capability
The battery and electric motor add approximately 580 pounds compared to a standard gasoline Wrangler. While the extra weight can slightly affect extreme off-road situations, the electric motor provides an important advantage.
Because electric motors produce maximum torque instantly, the Wrangler responds more smoothly when climbing rocks or crossing difficult terrain. Drivers have better throttle control without waiting for engine revs to build.
The Wrangler 4xe still retains its famous off-road features, including:
- Trail Rated capability
- Low-range four-wheel drive
- Locking differentials (on selected models)
- 30-inch water-fording depth
In everyday off-road driving, the extra electric torque often outweighs the added battery weight.
Wrangler 4xe Charging
| Method | Power | 17.3 kWh Wrangler 4xe |
|---|---|---|
| Level 1 (120V, included cable) | ~1.2 kW | ~12 hours full |
| Level 2 (240V, 7.2 kW) | 7.2 kW | ~2 hours full |
The onboard charger is a 32-amp unit, good for 7.2 kW on Level 2; on a household Level 1 outlet it draws only about 1.4 kW and adds roughly 2 miles of range per hour, which is why a full Level 1 charge takes about 12 hours.
Does the Wrangler 4xe Support DC Fast Charging?
No. The Jeep Wrangler 4xe does not support DC fast charging.
Because the battery is relatively small, Jeep designed the vehicle around AC charging instead. A roughly 2-hour Level 2 charge is already fast enough for most owners.
For daily use:
- Use the included 120V charger if overnight charging is acceptable.
- Install a 240V Level 2 charger for faster home charging.
- Public Level 2 chargers at workplaces and shopping centers also work well.
Real-World EV Range and Efficiency
- Urban driving (mild weather): 18–22 miles EV-only — consistent with EPA’s 21-mile figure in city conditions
- Highway driving: Approximately 12–16 miles EV-only — aerodynamics and speed reduce electric efficiency sharply
- Highway in hybrid mode: Approximately 22–23 mpg — better than any gasoline Wrangler but still below class average due to the body’s poor aerodynamics
- Off-road in EV mode: Battery lasts approximately 8–15 miles on gentle trails — enough for typical trail sections before the gasoline engine takes over
Wrangler 4xe Battery Warranty and Expected Degradation
Jeep, through Stellantis, covers the battery with an 8-year or 100,000-mile warranty.
The warranty protects the battery if its capacity falls below 70% during the warranty period. In CARB states — California and the states that follow its emissions rules — the same battery is covered for 10 years or 150,000 miles.
How fast does the pack actually age? There is no large independent degradation dataset for the 4xe yet. What is known is that a small plug-in hybrid pack works hard: it cycles deeply almost every day, so some loss of electric range over the years is normal, and owners typically notice it first as a mile or two less of EV range. The warranty above — and the lifetime extension described in the recall section below — is the real protection if the loss ever becomes excessive.
The relatively small usable battery window also reduces stress on the cells, helping improve long-term durability.
Wrangler 4xe Battery Recalls: What Owners Must Know
The 4xe’s Samsung SDI cells are the subject of the largest battery recall story in Jeep’s history. Some cells were built with damaged separators, which can let the pack fail internally and catch fire — in reported cases while the Jeep was parked and switched off. FCA has recalled the Wrangler 4xe three times for this defect.
- November 2023 (B9A / 23V-787): 32,125 Wrangler 4xes from 2021–2023. Owners were told to stop charging and park outside until a fix was ready.
- September 2024 (95B / 24V-720): 154,032 Jeeps, including 118,230 Wrangler 4xes. Thirteen fires had been reported, and FCA acknowledged the first remedy had not fixed the problem.
- October 2025 (68C / 25V-741): 320,065 Jeeps, including 228,221 Wrangler 4xes covering every model year, 2021–2025. Nineteen fires were on record — nine of them in vehicles that had already received the earlier fix.
The current remedy is a software update for the battery control module that can detect separator damage. If it flags a fault, the Jeep shows a warning, charging is disabled, and the battery pack is replaced free. Until your Jeep has had the remedy, FCA’s advice stands: park outside, away from buildings and other vehicles, and do not charge. You can check your VIN free on the NHTSA recalls page.
There is a significant upside to getting the recall done: under Stellantis’s XU1 warranty extension, completing the 68C remedy extends your high-voltage battery coverage to lifetime, unlimited miles. For a vehicle whose battery warranty would otherwise end at 8 years or 100,000 miles, that makes the recall visit one of the most valuable free services in the 4xe’s life.
Wrangler 4xe Battery Replacement Cost
If a pack fails outside warranty and outside the recalls, a full replacement is a five-figure job. A new Mopar pack has listed at around $15,000 for the part alone, and dealer quotes for the complete job are commonly reported in the $8,000–$12,000 range, depending on the parts route and labor.
In practice, most owners never see that bill. Failures inside 8 years/100,000 miles (10 years/150,000 miles in CARB states) are warranty work, recall-flagged packs are replaced free, and the XU1 extension turns completed-recall packs into lifetime coverage. The cost question matters mainly for high-mileage Jeeps bought cheaply out of warranty — price the risk in before buying.

Does the Wrangler 4xe Have a 12-Volt Battery?
Yes. Alongside the 17.3 kWh high-voltage pack, every Wrangler 4xe has a conventional 12-volt battery, just like a gasoline Wrangler. The 12-volt runs the lights, locks, screens and control systems, and it wakes the vehicle’s electronics up — a job the big pack cannot do by itself.
That makes the 12-volt a common cause of a confusing fault: a weak 12-volt battery can leave a 4xe showing warnings or refusing to start even when the main pack is fully charged. It typically lasts 3 to 5 years, and replacing it is a normal, inexpensive job compared with anything high-voltage. It is an AGM battery mounted under the hood, on the fender side.

Charging Tips for Wrangler 4xe Owners
- Use eSave Mode on the highway: Set eSave before long gasoline highway stretches to preserve a full battery for quiet EV trail driving
- Charge every night at home: The roughly 2-hour Level 2 charge time makes nightly full charges effortless — always start with a full 21-mile EV range daily
- Electric Mode on the trail: Switch to Electric Mode at the trailhead for a unique quiet off-road experience — the instant torque also improves precise low-speed rock crawling
- Use the departure timer: The Uconnect app allows scheduling charging to complete just before departure — avoids sitting at 100% for extended periods
Frequently Asked Questions
What size battery does the Jeep Wrangler 4xe have?
The Wrangler 4xe has a 17.3 kWh lithium-ion pack (about 15 kWh usable) built from 96 Samsung SDI NMC cells, mounted under the rear seat on a 400V system. It delivers 21 miles of EPA electric range and 370 miles of total range with the gasoline engine.
How long does the Wrangler 4xe battery last?
There is no large independent degradation dataset for the 4xe yet, but the pack is built to outlast its 8-year/100,000-mile warranty (10 years/150,000 miles in CARB states). Small plug-in packs cycle deeply every day, so a gradual loss of a mile or two of EV range over the years is normal. Owners who complete the 68C recall get lifetime battery coverage under Stellantis’s XU1 extension.
Is the Wrangler 4xe battery recalled?
Yes — three times, for a fire risk from damaged separators inside some Samsung SDI cells. The latest recall (68C, October 2025) covers every Wrangler 4xe, 2021–2025. Until the free software remedy is done, park outside and do not charge. Check your VIN on the NHTSA recalls page.
How much does a Wrangler 4xe battery replacement cost?
Out of warranty, a new Mopar pack lists at around $15,000 for the part, and complete dealer jobs are commonly quoted at $8,000–$12,000. Most owners never pay it: failures are usually covered by the battery warranty, the recalls, or the XU1 lifetime extension.
Does the Wrangler 4xe have a 12-volt battery?
Yes — a conventional 12-volt battery runs the lights, locks, screens and control systems, separate from the 17.3 kWh pack. It lasts about 3 to 5 years, and a weak one can cause warnings or a no-start even when the main battery is fully charged.
What is the Wrangler 4xe battery warranty?
8 years or 100,000 miles in most states, and 10 years or 150,000 miles in CARB states. Completing the 68C fire-risk recall extends the coverage to lifetime, unlimited miles under Stellantis’s XU1 extension.
Can you drive the Wrangler 4xe without charging it?
Yes. The Wrangler 4xe will continue to drive even if you do not charge the battery. Once the battery runs out, the 4xe switches to hybrid mode, using the gasoline engine to keep going. That means it is never stranded, though you will miss the electric-only range benefits.
Does cold weather affect the Wrangler 4xe battery range?
Yes. Like all lithium-ion batteries, cold temperatures reduce battery efficiency. In winter, the Wrangler 4xe may deliver less than its 21-mile EPA electric range, especially if cabin heating is used. Charging the battery before driving and preconditioning the cabin while plugged in can help improve cold-weather performance.
Conclusion
The Jeep Wrangler 4xe battery is uniquely purposeful — 17.3 kWh of lithium-ion power that delivers 21 miles of EV range, 375 hp, and the ability to crawl trails in near silence. Buyers wanting the same PHEV powertrain in a more family-friendly SUV should see our Jeep Grand Cherokee 4xe battery guide. But for owners who genuinely need a capable 4WD off-road vehicle for weekends and use it for daily commuting during the week, the 4xe’s battery delivers real-world value through reduced fuel costs and a uniquely quiet trail experience. It earned its place as America’s best-selling plug-in hybrid for good reason.
