Detect Battery Weakness Before Emergency No-Start

Cost Savings

Checklist Tasks

• Check battery age using date code to estimate remaining service life.
• Inspect terminals for corrosion; clean to prevent voltage drop and start issues.
• Test resting voltage after an overnight sit to detect sulfation or internal short.
• Ensure hold-down bracket is tight to prevent vibration-induced plate damage.
• Look for swelling or bulging to catch overheating or overcharging risk early.
• Measure alternator output at idle to verify battery is properly charged.
• Inspect cables for cracked insulation to prevent intermittent starting.
• Check for parasitic drain by measuring current draw with vehicle off.
• Look for acid residue or moisture as signs of leaks or vent failure.
• Test cold cranking amps to confirm battery meets starting requirements.
• Examine battery tray for rust or acid damage that could affect grounding.
• Review short-trip driving patterns which can prevent proper battery recharge.
