What does a battery health test tell me?

The Konnwei KW720 measures four things simultaneously: state-of-health (as a percentage of original capacity), cold cranking amps (CCA — actual vs rated), internal resistance (a key indicator of degradation), and open-circuit voltage. Together, these tell you clearly whether the battery is healthy, needs charging, needs desulfation, or genuinely needs replacement.

Q: What if the test shows my battery is fine?

We tell you it's fine. We will not recommend a service you don't need. If the battery shows healthy numbers on the KW720, we say so clearly and suggest no further action. We have been doing this honestly since 2014 — it is the only reason customers come back.

Konnwei KW720 battery health test being performed in East of Kailash, South Delhi by 12v PitStop technician

BATTERY TEST · SOUTH DELHI

What the test measures

Four numbers that tell you everything about your battery.

The Konnwei KW720 measures all four simultaneously in under 30 seconds. You see the actual readout — not a mechanic's opinion.

SOH%

State of Health

Percentage of original capacity remaining. Below 70% and you'll notice sluggish starts and poor backup. Below 50% — replacement is genuinely needed.

CCA

Cold Cranking Amps

The actual amps the battery can deliver vs. its rated spec. A 600 CCA battery delivering only 350 CCA is failing — even if it still starts the car on a warm morning.

IR mΩ

Internal Resistance

The single most reliable indicator of battery degradation. As plates corrode and sulphate builds up, resistance rises — stealing power before it reaches the starter motor.

Open Circuit Voltage

Resting voltage shows current charge state. Combined with SOH and IR, this tells us whether the problem is a discharged battery or a genuinely degraded one.

Sound familiar?

You need a battery test if any of these apply.

A mechanic told you to replace the battery — but gave you no data, just an opinion

Battery is 3–4 years old and you don't know if it will survive one more Delhi summer

Car takes a few extra cranks to start — could be a weak battery or a dying alternator

Battery was recently replaced and you're not sure it's the right spec for your car

Headlights dim when the engine is at idle — possible sign of a charging or battery issue

Car has been sitting unused for months in your CR Park or Kalkaji parking — need to know if battery is still good

How it works

From booking to honest report — in one visit.

30-minute arrival at your parking

Technician arrives with the Konnwei KW720 and additional equipment. Miss the 30-minute window? The test is completely free. Our technician goes straight to your battery — no wasted time.

Konnwei KW720 connected — results in 30 seconds

The KW720 is connected to the battery terminals. Within 30 seconds it displays state-of-health, CCA (actual vs. rated), internal resistance in milliohms, and open-circuit voltage. This is a professional digital readout — not a guess or a load test.

Technician explains results in plain language

You receive the exact numbers and a clear explanation: healthy and no action needed; chargeable with a CTEK session; recoverable with desulfation; or genuinely failed and replacement is warranted. No jargon, no pressure.

Honest recommendation — your choice

If the battery is fine, we tell you and leave. If a service would help, we quote the price and you decide — no pressure, no obligation. We will never recommend a ₹10,000 battery when a ₹499 charge session would fix the problem.

Our equipment

Why the Konnwei KW720 is the right tool for an honest diagnosis.

Primary Tester

Konnwei KW720

A professional 100–2000 CCA battery analyser that measures state-of-health, internal resistance, CCA, and open-circuit voltage simultaneously. Accurate to within 2%. Tests AGM, EFB, GEL, WET, and deep-cycle batteries. Gives a digital readout in under 30 seconds — not a guess or a rough estimate.

✓ Industry-grade accuracy · Tests all chemistries · Results you can trust and verify

Follow-up Charger

CTEK Battery Chargers

If the KW720 shows the battery is discharged but fundamentally healthy, we can perform a CTEK smart charge on the same visit. The 8-stage algorithm recovers the battery correctly — not the dangerous overcharging done at roadside shops.

✓ AGM, EFB & lead-acid modes · Never overcharges · Extends battery life

If Needed

OzCharge RM 1000

If the battery is too flat to hold a charge for the KW720 to read accurately, the OzCharge RM 1000 capacitor jump starter safely brings it to a testable voltage level — without voltage spikes that could corrupt the test or harm the car's electronics.

✓ Spark-free · Safe for modern ECUs · No external power source needed

Our technicians

We show you the numbers. You make the decision.

We've been testing batteries across East of Kailash, Nehru Place, Okhla, Lajpat Nagar, and South Delhi since 2014. Our reputation is built entirely on honest diagnoses — customers come back because we never pushed a service they didn't need.

10+ years testing batteries across 100+ car brands and all battery chemistries

Trained to interpret KW720 readings correctly — not just read numbers off a screen

Will never recommend replacement unless SOH is below threshold and CCA confirms it

Explains what each number means in plain language — no jargon, no pressure

Common questions

Battery testing FAQs — honest answers.

What does the battery health test tell me?

The Konnwei KW720 measures four things simultaneously: state-of-health (percentage of original capacity remaining), cold cranking amps (actual vs. rated), internal resistance (key degradation indicator), and open-circuit voltage. Together, these tell you clearly whether the battery is healthy, needs charging, needs desulfation, or genuinely needs replacement — with numbers to back every conclusion.

How is this different from what a mechanic does?

Most mechanics use a basic load tester or just look at voltage with a multimeter — neither gives an accurate picture of true battery health. The Konnwei KW720 measures internal resistance and state-of-health, which are the only reliable indicators of real battery condition. This is why we can tell you with certainty whether replacement is justified.

Is the test free?

The battery health test is ₹299 + GST as a standalone service. It is completely free when combined with any other service — jump start, smart charging, desulfation, or inverter service. We include a test before and after every service visit regardless.

What if the test shows my battery is fine?

We tell you it's fine and recommend no action. We will not suggest a service you don't need. If the battery shows healthy numbers on the KW720, we say so clearly. Our reputation has been built on this honesty since 2014.

Can you test my battery in CR Park or Defence Colony?

Yes — we cover CR Park, Defence Colony, Kalkaji, Greater Kailash I & II, Saket, and all areas within 5 km of East of Kailash in South Delhi. We arrive within 30 minutes or the test is free.
