Q: What does the diagnosis test?

The Konnwei KW720 measures state-of-health (as a percentage of original capacity), cold cranking amps (actual vs rated), internal resistance, and open-circuit voltage. These four numbers together give a complete picture of the battery's true condition — whether it's healthy, needs charging, needs desulfation, or genuinely requires replacement.

Q: How long does the diagnosis take?

The Konnwei KW720 test itself takes under 30 seconds once connected. The technician then explains the results and answers your questions — typically 10–15 minutes for the full visit. We never rush the explanation.

Mechanic said replace the battery. But did they show you the numbers? We come to your car across South Delhi — East of Kailash, Nehru Place, Okhla, Lajpat Nagar, South Extension, Greater Kailash, Kalkaji, CR Park, Defence Colony and Saket. We test with the Konnwei KW720, explain results honestly, and recommend only what the data supports. No charge, ever.

FREE DIAGNOSIS · SOUTH DELHI

What's included — free

What you get from a free diagnosis visit.

No strings attached. This is what we do on every diagnosis visit — whether you book a service afterward or not.

Konnwei KW720 Battery Test

State-of-health, cold cranking amps (actual vs rated), internal resistance, and open-circuit voltage. Four numbers that together give a complete, accurate picture of your battery's real condition — far more than a multimeter or a load test.

Honest Explanation of Results

Your technician explains what each number means in plain language. Not just "battery is weak" — you hear the exact SOH percentage, what the internal resistance reading means, and what threshold would trigger a replacement recommendation.

No-Pressure Recommendation

If the battery is fine, we tell you and leave. If it needs a service, we quote the price and you decide — no follow-up pressure, no guilt, no minimum charge. We do not benefit from recommending a service you don't need.

Doorstep at Your Car in South Delhi

We come to your parking — basement, roadside, or open lot — across East of Kailash, Nehru Place, Okhla, Lajpat Nagar, Defence Colony, CR Park, Kalkaji, Greater Kailash I & II, Saket, and South Extension.

10+ Year Trained Technician

An experienced technician handles every visit — not a helper. They have seen every failure mode across every car brand and battery chemistry. They will not misread a KW720 result or give you a wrong recommendation.

Zero Cost — Even If We Can't Help

If the battery is beyond what any of our services can address, we tell you — still at no charge. If we recommend a replacement, we explain exactly what spec to look for and why. We do not sell batteries, so there's no conflict of interest.

Technician explains results in plain language

Every number is explained clearly — what it means for your battery's remaining life, what's causing the problem (if any), and what the right fix is. No jargon, no scare tactics, no pressure. If the battery is fine, we tell you and leave.

Our equipment

The tool we use for every free diagnosis.

Primary Tester

Konnwei KW720

A professional 100–2000 CCA battery analyser measuring state-of-health, internal resistance, CCA, and open-circuit voltage simultaneously. Accurate to within 2%. Tests AGM, EFB, GEL, WET, and deep-cycle batteries in one 30-second test. This is what gives us the authority to say "yes, replace it" or "no, don't" — with evidence.

✓ Professional-grade accuracy · All battery chemistries · Digital readout — not a guess

If Service Needed

CTEK Battery Chargers

If the KW720 shows the battery is discharged or sulphated but not dead, we offer a CTEK smart charge or desulfation session on the same visit. Patented 8-stage algorithm — the right fix for batteries that don't need replacement.

✓ AGM, EFB & lead-acid modes · Desulfation built-in · Extends battery life by years

If Urgently Needed

OzCharge RM 1000

If the battery is too flat to give an accurate KW720 reading, the OzCharge RM 1000 capacitor jump starter safely brings it to a testable voltage level without damaging the car's electronics. We can then test accurately and diagnose correctly.

✓ Spark-free · Safe for modern ECUs · No voltage spikes that could affect test results

Common questions

Free diagnosis FAQs.

Is the diagnosis really free? What's the catch?

There is no catch. The diagnosis is completely free — no charge for the Konnwei KW720 test or the technician's visit. We offer it because we believe in test-first, not sell-first. If the test shows a service is needed, we quote the price and you decide. No obligation, no follow-up pressure. We've built our reputation since 2014 on this approach.

What does the diagnosis test?

The Konnwei KW720 measures state-of-health (percentage of original capacity remaining), cold cranking amps (actual vs rated), internal resistance (the key indicator of battery degradation), and open-circuit voltage. These four numbers together give a complete, accurate picture of your battery's real condition.

What if the diagnosis shows I need a new battery?

We show you the exact KW720 numbers and explain what they mean in plain language. If replacement is genuinely the right answer, we say so and can refer you to a battery supplier. We do not sell batteries ourselves — our only interest is giving you an honest report.

How long does the diagnosis take?

The Konnwei KW720 test takes under 30 seconds once connected. The technician then explains the results and answers questions — typically 10–15 minutes for the full visit. We never rush the explanation. If you want to proceed with a service after the diagnosis, it can start immediately on the same visit.

What if my car is in a basement parking in Defence Colony or CR Park?

Most of our calls come from apartment basements — it's the most common scenario. Just share the entry gate details, floor, slot number, and any visitor access code when booking. Our technician comes directly to your car. Defence Colony, CR Park, Greater Kailash, and Kalkaji are all within our 30-minute zone.
