< strong >Yes, but with caution—the 2017 Bolt EV has a 12V auxiliary battery that can be jump-started using standard methods. However, improper handling risks damaging the high-voltage system. This guide covers safe steps, tools needed, and why professional help is recommended for severe cases.
This is a comprehensive guide about 2017 bolt ev 12v can you jump start.
Key Takeaways
- 12V vs. High-Voltage: Only the 12V accessory battery needs jump-starting; the main high-voltage pack requires a tow or service.
- Safety First: Disconnect the high-voltage service plug (orange) before attempting any repairs to avoid electric shock.
- Tools Needed: A compatible jumper cable set and a donor car with a working 12V battery are essential.
- Limitations: Frequent jump-starts may indicate a deeper issue (e.g., alternator failure).
- Tow as Backup: If unsure, call roadside assistance instead of risking damage.

2017 Bolt Ev 12V Can You Jump Start?
## Introduction
If your 2017 Chevy Bolt EV won’t crank, you might wonder: *Can I jump-start it like a traditional car?* The answer is yes—but only for its 12V auxiliary battery, which powers lights, infotainment, and other electronics. Unlike gasoline vehicles, the Bolt’s high-voltage (HV) battery pack cannot be jump-started. Missteps here could lead to costly repairs or even injury. Let’s break down how to safely revive your Bolt’s 12V system without risking the HV components.
### Why the 12V Battery Matters
The Bolt EV uses two separate power systems:
– High-Voltage (HV) Pack: Powers the electric motor (requires professional recovery).
– 12V Auxiliary Battery: Powers low-voltage accessories (jump-startable).
A dead 12V battery often leaves the car inoperable, making it frustrating—but solvable!

How to Jump-Start a 2017 Bolt EV’s 12V Battery
### Step 1: Safety Precautions
Before connecting jumper cables:
- Turn off both cars (ignition, lights, AC).
- Park donor car close (within 6 feet) to avoid cable strain.
- Wear insulated gloves and avoid metal jewelry near terminals.
- Locate the HV service plug (orange cap behind the driver-side seat) and disconnect it. This prevents accidental HV activation during jump-starting.
### Step 2: Connect Jumper Cables Correctly
Use a 4-gauge jumper cable set (thick wires handle higher current). Follow this sequence:
- Red (+) to donor car’s positive terminal.
- Other red (+) to Bolt’s positive terminal.
- Black (-) to Bolt’s negative terminal first.
- Last black (-) to an unpainted metal surface on the donor car’s engine block. (Direct grounding reduces spark risks.)
### Step 3: Revive the Bolt
- Start the donor car and let it idle for 5 minutes.
- Reconnect the HV service plug after Bolt starts (if needed).
- Test all 12V functions (lights, radio) to confirm success.
### Common Mistakes to Avoid
– Connecting black cables backward: Sparks can ignite fumes.
– Forgetting to disconnect the HV plug: Risk of electrical surge.
– Using damaged cables: Thin wires overheat and fail.

What if Jump-Starting Fails?
If the Bolt doesn’t start after following steps above:
- Recharge the 12V battery with a portable jump starter (e.g., NOCO Boost Plus G788).
- Check for parasitic drains (e.g., faulty module draining the battery overnight).
- Call a mechanic: Persistent issues suggest alternator failure or a bad cell in the 12V battery.
### When to Call for Help
– Horn/steering wheel lights stay on: Indicates a deeper electrical fault.
– Battery dies within days: Likely a charging system problem.

Alternatives to Jump-Starting
### Portable Jump Starters
Pros:
– No need for a donor car.
– Compact and reusable.
Cons:
– Lower amperage than a full jump (may take longer).
Recommended models:
– NOCO Boost Plus G788 (up to 1000A output).
– Cigarette Lighter Jump Starter (for basic needs).
### Recharging the 12V Battery
If your Bolt has a 12V charger port (some models do), use a DC-DC charger to recharge slowly overnight.

Preventing Future 12V Battery Failures
### Regular Maintenance
– Monthly checks for battery corrosion (clean terminals with baking soda + water).
– Keep it charged: If parking long-term, use a trickle charger.
### Upgrades
– Auxiliary battery upgrade: Opt for a deep-cycle battery (e.g., Trojan T-105) for longevity.
– Install a solar panel: Maintains charge while parked.

## Conclusion
Jump-starting a 2017 Bolt EV’s 12V battery is possible—but always prioritize safety. Disconnect the HV system, use proper cables, and don’t force it if something feels off. For recurring issues, consult a GM-certified technician to diagnose root causes. With these tips, you’ll keep your Bolt running smoothly and avoid costly surprises on the road!

FAQs
Can a 2017 Bolt EV be towed instead?
Yes, if the 12V battery is dead, most towing services will assist. However, they won’t jump-start it—you must follow the steps above or use a portable charger.
Is there a warranty for the 12V battery?
The 12V battery typically has a 3-year warranty under GM coverage. Check your owner’s manual or dealer for details.
What if my Bolt’s lights stay on after starting?
This suggests a parasitic drain. Disconnect the 12V battery for 15 minutes to reset modules, then reconnect.
Can I use a car battery charger?
Absolutely! Use a smart charger (like CTEK MXS 20) to recharge the 12V battery slowly overnight.
Are there signs my 12V battery is failing?
Dim lights, slow cranking, or frequent jump-start attempts are warning signs. Test voltage with a multimeter (< 12.4V indicates weakness).
