To recharge the 12‑volt battery in a 2013 Ford Explorer, you can either jump-start it from another vehicle or use a dedicated 12V battery charger, then let the alternator bring the battery to full—driving the vehicle if needed. If the battery won’t take a charge or keeps dying, replacement may be necessary.
In more detail, the Explorer uses a conventional 12‑volt lead‑acid battery charged by the alternator when the engine runs. If the battery is deeply discharged or experiences parasitic drain, you’ll typically revive it with a controlled charge or a jump-start, while observing safety guidelines. Always consult your owner's manual for model-specific warnings and check the battery's label for capacity and CCA (cold-cranking amps) before charging or replacing it.
Safety and preparation
Before you begin, gather the right equipment and review basic safety steps to minimize risk.
- Safety gear: wear protective glasses and gloves to guard against acid and sparks.
- Right equipment: have a pair of Jumper cables or a portable jump starter, and a compatible 12V battery charger if you’re charging directly.
- Vehicle readiness: park on a flat surface, engage the parking brake, and keep the engine off with keys removed.
- Battery condition: inspect for cracks, bulges, or corrosion on terminals. Do not attempt to charge a damaged battery.
With safety checks complete, choose the method that fits your situation (jump-start or charging). If you notice a strong sulfur smell, smoke, or a swollen case, stop and seek professional help immediately.
Jump-starting a dead battery
Step-by-step procedure
If your Explorer’s battery is completely dead, a safe jump-start can get you moving again without a full charge from a charger.
- Position the donor vehicle close enough for cables to reach both batteries, but do not let the vehicles touch.
- Turn off both engines, set the parking brakes, and open the hoods.
- Connect the donor’s positive (red) clamp to its positive terminal and to the Explorer’s positive terminal.
- Connect the donor’s negative (black) clamp to its negative terminal or to a solid, unpainted metal surface on the Explorer’s engine or chassis away from the battery.
- Start the donor vehicle and let it run for a few minutes, then attempt to start the Explorer.
- If the Explorer starts, let it run and then remove the clamps in reverse order: negative from the engine or chassis, negative from donor, positive from Explorer, then positive from donor.
- Drive or idle with the Explorer running for 20–30 minutes to allow the alternator to recharge the battery.
Concluding: If the vehicle doesn’t start after a reasonable boost or dies again shortly after, the battery or alternator may be failing and warrant a professional battery test or replacement.
Charging with a 12V battery charger
Step-by-step procedure
For a controlled recharge, use a dedicated 12V battery charger rather than repeated jump-starts.
- Park on a level surface, engine off, all accessories off, and remove the key.
- Inspect and clean battery terminals and connections if needed to ensure a solid contact.
- Attach the charger’s red clamp to the battery’s positive terminal, ensuring a secure connection.
- Attach the charger’s black clamp to a clean metal ground on the vehicle (not the positive terminal) or to the battery’s negative terminal.
- Set the charger to an appropriate charging rate (typically 2–6 amps for a standard car battery). For a deeply discharged battery, a lower rate or a dedicated “maintenance/float” mode is safer.
- Plug in the charger and monitor progress. Modern chargers with auto-stop features will indicate when charging is complete.
- When the charge is complete, disconnect clamps in reverse order (negative first, then positive) and recheck the battery voltage.
- Start the engine to confirm the alternator is charging; a healthy system should show about 13.8–14.4 volts with the engine running.
Concluding: If the battery cannot accept charge, or if it drops quickly after charging, the battery likely needs replacement and you should have the alternator and electrical system tested for underlying issues.
Aftercare and tests
Once the charging process is finished, perform quick checks to gauge long-term reliability.
- With the engine running, measure the voltage at the battery terminals; a healthy charging system typically reads 13.8–14.4V.
- Inspect for corrosion on terminals and clean as needed to maintain a solid electrical connection.
- Consider having the battery's health tested at a shop or with a handheld tester to confirm remaining capacity and CCA.
- Replace the battery if it’s old (commonly 3–5 years or more) or if it repeatedly fails a charge test.
Concluding: Regular maintenance and timely battery replacement help prevent unexpected no-start situations and keep the Explorer reliable on the road.
Summary
Charging a 2013 Ford Explorer’s 12‑volt battery can be safely achieved through jump-starting or with a dedicated charger. Always follow safety guidelines, monitor the charging process, and test the battery and charging system if starts become unreliable. When in doubt, a professional diagnostic can pinpoint whether the issue lies with the battery, the alternator, or parasitic drains.
