Warning signs

Is Your Hybrid Battery Failing?

Hybrid batteries in Pakistan typically weaken 4 to 5 years after import due to heat and dust. If you spot these signs, get a diagnostic before the problem spreads to other cells.

Red Triangle of Death

The hybrid system warning light comes on, often with codes P0A80 or P3000 on the scanner.

Weak Acceleration

The engine struggles alone to climb hills or merge into traffic, especially in summer heat.

Fuel Economy Dropping

Average falling from 18–22 km/l to 11–13 km/l means the engine is doing all the work.

SOC Bouncing Wildly

The charge gauge jumps from full to low in minutes, then recovers. A classic weak-cell sign.

Battery Fan Running Loud

The cooling fan runs constantly because the pack is overheating from cell imbalance.

Stalling or Limp Mode

The hybrid system shuts down mid-drive. The latest stage of failure. Needs immediate attention.

Hybrid battery failure in Pakistan

Why Packs Fail, and How We Bring Them Back

Pakistan's heat and dust are brutal on NiMH chemistry. Most imported hybrids arrive 4 to 5 years old, the original cooling fans clog with dust, and summer temperatures above 40°C degrade individual cells until they drag down the whole pack.

We regenerate packs for the Prius, Aqua, Axio, Vitz, Crown, Camry, Fielder and more: capacity testing of every module, segregating the best cells by Ah and IR, replacing bad cells and balancing the pack. All work is done by our engineers on advanced lab equipment with 100% power backup.

  • Brand-new hybrid batteries for long-lasting performance
  • Used and reconditioned Aqua and Prius batteries at affordable prices
  • Individual hybrid battery cells for precise repairs
  • Repair services with pre-checkups to optimize battery health

What we do

Battery Services Grounded in Testing

Every job follows a structured workflow, not guesswork.

Computer Diagnostics

Full OBD-II computer diagnostics reads live cell data, fault codes and pack health before any work.

Annual Cell Balancing

Equalizes cell voltages across all modules for consistent pack performance.

Fan & Cooling Service

Cleans the cooling fan and air paths for proper thermal management.

Polishing HV Strips

Removes oxidation from high-voltage strips, reducing internal resistance.

Capacity Testing per Cell

Tests every module for Ah and IR, then segregates the best cells for your pack.

Module Replacement

Swaps failed cells with tested replacements, balanced to factory tolerances.

FAQ

Frequently Asked Questions

How long does a hybrid battery service take?

A diagnostic takes 30 to 45 minutes. Cell balancing and minor service is completed the same day. Module replacement and pack rebuild typically take 1 to 2 working days. Full lithium upgrade conversions take 4 hours of in-car time once the pack is built.

Should I repair, replace, or upgrade?

If only one or two cells are weak and the rest of the pack is healthy, repair is the cheapest option. If multiple cells are degraded or the pack is over 5 years old, replacement is more reliable. If you want much more electric range and the ability to plug in at home, the lithium upgrade is the long-term solution. Our computer diagnostics tells us which path is right for your pack.

What kind of warranty do you offer?

Repair jobs come with a 6 to 12 month warranty depending on scope. Replacement packs (new or reconditioned) include a written warranty matched to the pack type. Lithium upgrade conversions include a full 2-year warranty on parts and labor.

Why do hybrid batteries fail in Pakistan?

Heat and dust are brutal on NiMH chemistry. Most imported hybrids arrive 4 to 5 years old, the original cooling fans clog with dust, and summer temperatures regularly exceed 40°C. Individual cells degrade and drag down the entire pack. Annual servicing prevents this.

Do you serve customers outside Islamabad and Rawalpindi?

Yes. Customers travel to our I-9/3 Islamabad and Rawalpindi branches from Lahore, Karachi, Peshawar, Faisalabad and beyond. We also ship batteries and modules nationwide via TCS and Leopards. Diagnostics happen in person, but post-purchase support is fully remote.

What happens to my old battery?

We take it in as part of the service. Healthy modules go back into reconditioned stock, and end-of-life cells are disposed of responsibly per Pakistani environmental guidelines. You don't pay disposal fees.
