What’s the Best Battery for a 2014 Kia Soul?
The best battery for a 2014 Kia Soul is a Group 35 or 24F size with at least 550-650 CCA (Cold Cranking Amps). Opt for AGM (Absorbent Glass Mat) batteries for enhanced durability or standard lead-acid for budget-friendly options. Top brands include Optima, DieHard, and Interstate. Always verify compatibility using your owner’s manual or VIN-based tools before purchasing.
How Do You Replace the Battery in a 2014 Kia Soul?
Disconnect the negative (-) then positive (+) terminals using a 10mm wrench. Remove the hold-down clamp securing the battery. Lift out the old battery (average weight: 35-45 lbs). Clean corrosion from terminals with baking soda/water. Install the new battery, secure the clamp, and reconnect terminals in reverse order (positive first). Reset electronic systems like windows and radio presets afterward.
What Size Battery Does a 2014 Kia Soul Require?
The 2014 Kia Soul uses either Group 35 (12″ x 6.8″ x 7.5″) or Group 24F (10.3″ x 6.8″ x 8.9″) batteries. Key specifications include 12V voltage, 55-75Ah capacity, and 550-720 CCA. Variations exist between base models and turbocharged engines—consult your VIN or dealership for exact requirements. Aftermarket modifications may alter these specifications.
Why Does the 2014 Kia Soul Battery Drain Quickly?
Common causes include parasitic draws from aftermarket electronics (dash cams, GPS), faulty alternators (output below 13.5-14.8V), or extreme temperatures. Testing with a multimeter can identify drains exceeding 50mA. Software glitches in the Soul’s UVO infotainment system may also contribute. Regular maintenance checks reduce unexpected drainage issues.
To diagnose parasitic drain, use a multimeter set to DC amps. Disconnect the negative battery terminal and connect the meter between the terminal and cable. If the reading exceeds 50 milliamps after 45 minutes (allowing systems to sleep), start pulling fuses one by one to isolate the circuit causing the drain. Common culprits include aftermarket alarms, USB chargers left plugged in, or malfunctioning interior lights. For alternator testing, measure voltage at the battery terminals while the engine runs—it should read between 13.7-14.7V. Lower values indicate a failing alternator unable to recharge the battery properly.
When Should You Upgrade to an AGM Battery?
Upgrade to an AGM battery if you frequently use accessories (heated seats, high-end audio) or live in extreme climates (-20°F winters or 100°F+ summers). AGM batteries offer 2-3x longer lifespan (6-8 years vs. 3-5) and withstand 300+ discharge cycles. They’re leak-proof and vibration-resistant, ideal for the Soul’s compact engine bay.
What Battery Is Used in Telecom Towers?
| Feature | AGM Battery | Standard Lead-Acid |
|---|---|---|
| Cycle Life | 500-600 cycles | 200-300 cycles |
| Vibration Resistance | Excellent | Moderate |
| Maintenance | Sealed design | Requires venting |
The higher upfront cost of AGM batteries (typically $200-$300) offsets reduced replacement frequency. They’re particularly beneficial for Souls equipped with start-stop technology, as they handle frequent engine restarts better. Ensure your vehicle’s charging system supports AGM technology before upgrading—some older alternators may require voltage regulator adjustments.
Can You Jump-Start a 2014 Kia Soul Safely?
Connect red clamp to dead battery’s positive (+) terminal, then donor battery’s positive. Attach black clamp to donor’s negative (-), then grounded metal on the Soul (e.g., engine bracket). Start donor vehicle, wait 2-3 minutes, then attempt to start the Soul. Avoid reversed connections—they can damage the $800+ ECU. Post-jump, drive 30+ minutes to recharge.

What Are Signs of a Failing 2014 Kia Soul Battery?
Key indicators include slow cranking (over 3 seconds), dimming headlights at idle, and recurring “Check Battery” warnings. Test voltage: below 12.4V signals weakness. Swollen cases or sulfur smells indicate critical failure. Average lifespan is 3-5 years—replace proactively if nearing this range or before winter.

Expert Views
“The 2014 Soul’s battery placement near heat sources accelerates wear. We recommend thermal wraps for drivers in hot climates. Also, avoid aftermarket battery monitors that tap into CANBUS systems—they can trigger false error codes. Always use a memory saver during replacement to preserve ECU settings.”

FAQs
- Does the 2014 Kia Soul have a battery warranty?
- Original batteries had 48-month coverage, now expired. New replacements carry 18-36 month warranties—Interstate offers prorated coverage up to 100 months.
- Are Costco batteries compatible with the 2014 Soul?
- Yes—Costco’s Kirkland Signature Group 35 (650 CCA) meets specifications. Membership pricing averages $110-$140, including core exchange.
- Can a bad battery cause transmission issues?
- Yes—low voltage disrupts the Soul’s TCM (Transmission Control Module). Symptoms include harsh shifts or limp mode. Always test battery before diagnosing transmission faults.
