Overview

About our inverter & cooling service

Almost every hybrid battery we replace failed early for the same reason: it could not shed heat. Karachi summers, D.H.A traffic and a fan full of dust are a brutal combination. Cleaning the battery cooling fan, the intake duct and the inverter cooling circuit is cheap, quick, and is the single highest-return maintenance item on any hybrid. We also include it free with every battery we fit, and repeat it every three months for our customers.

Cooling fan strip and clean

Fans removed, cleaned and tested for correct speed and current draw — a lazy fan is a silent battery killer.

Duct and intake clearing

Intake grilles, ducts and the cabin filter path cleared so airflow actually reaches the pack instead of stalling in a clogged channel.

Inverter coolant service

Coolant level, condition and pump operation checked, and the circuit topped or flushed where the interval has been missed.

Temperature verification

Inlet and pack temperatures logged after the clean so you can see the improvement in real numbers.

How it runs

Inverter & cooling service, step by step

  1. Inspect and log

    We read current pack temperatures and fan behaviour so we have a genuine baseline before touching anything.

  2. Clean and service

    Fans out, cleaned, tested; ducts cleared; coolant checked. Most of the debris we remove is fine dust that has been compacted for years.

  3. Verify by data

    Temperatures re-logged after the service. A healthy car should shed heat noticeably faster in the same conditions.
