Repair or Replace

Module replacement or full pack - your choice

Safety Certified

High-voltage trained technicians, proper equipment

Understanding Hybrid Battery Failure

What happens when your HV battery degrades

Hybrid Warning Light

Triangle with exclamation mark, or "Check Hybrid System" message - primary indicator of battery issues.

Reduced Fuel Economy

Battery can't hold charge, engine runs more often, fuel consumption increases significantly.

Loss of Power

Sluggish acceleration, can't maintain highway speeds, struggles on inclines - limited electric assist.

Battery State of Charge Fluctuates

SOC meter jumps around erratically, doesn't charge properly, or drains quickly under load.

Engine Runs Constantly

Even at idle or low speed, engine stays on trying to charge battery - defeats hybrid purpose.

Age-Related Degradation

8-10+ years old, over 150,000 km - natural capacity loss even without warning lights yet.

Our HV Battery Diagnostic Process

Scan Diagnostic Codes

Read hybrid system fault codes using manufacturer-specific scanner. Identify which battery modules flagged.

Cell Voltage Testing

With proper safety equipment, test individual cell/module voltages. Identify weak or imbalanced cells.

Load Testing

Perform discharge test under load to see which modules can't sustain voltage - reveals capacity loss.

Cooling System Check

Inspect battery cooling fan and ducts. Overheating accelerates degradation - must work properly.

Detailed Report

Provide cell voltage chart, explain which modules failing, repair vs replace recommendation with costs.

Safety Inspection

Check high-voltage cable insulation, connectors, service plug - ensure system safe to repair.

Repair vs Full Replacement

Module-Level Repair

If only a few battery modules (cells) are weak, we can replace those specific modules rather than the entire pack. This is more cost-effective.

  • Replace 1-6 weak modules
  • Significantly lower cost
  • Extends pack life by several years
  • Warranty on replaced modules
  • 1-2 day turnaround

Best for: Packs with isolated cell failures, 5-8 years old

Cost range: $800-$2,000

Full Pack Replacement

If many modules degraded or pack severely damaged, full replacement with new or reconditioned pack is recommended.

  • Complete new/reconditioned pack
  • All cells matched and balanced
  • Full warranty coverage
  • Best long-term reliability
  • 2-4 day turnaround

Best for: Very old packs (10+ years), widespread failure

Reconditioned: $1,500-$3,000 | New OEM: $3,500-$5,000+

Frequently Asked Questions

How much does hybrid battery replacement cost in Singapore?

Costs vary by model. Reconditioned packs: $1,500-$3,000. New OEM: $3,500-$5,000+. We provide detailed quote after diagnosis. Some batteries can be repaired at lower cost.

Can hybrid batteries be repaired instead of replaced?

Yes, in many cases. If only a few cells are weak, we can replace those specific modules. This is significantly cheaper than full pack replacement and extends battery life.

How long do hybrid batteries last in Singapore?

Typically 8-10 years or 150,000-200,000 km. Singapore's heat can shorten lifespan. Regular driving (not sitting idle) helps maintain battery health.

Is it safe to drive with hybrid battery warning light on?

You can still drive, but performance will be reduced and fuel economy poor. Engine may run constantly. Get diagnosed soon - delaying can cause further damage to battery.

Do you offer warranty on hybrid battery service?

Yes, all our battery repairs and replacements come with warranty. Duration varies by service type - we'll provide full warranty details with quote.

Can I get my hybrid battery checked before it fails?

Absolutely. If your hybrid is 6+ years old, proactive health check recommended. We can predict when battery may fail and plan replacement before breakdown.
