Ask our teamCan a QR code on a lithium cell be faked?
Yes. The code is laser-etched, and re-etching a cell is a cheap, routine service in the trade — roughly a dollar a cell, less in quantity. A used or downgraded cell with a fresh code will scan correctly. That is why a scannable code proves only that someone put a valid code on the cell, not that the cell is new.

Ask the seller for the batch test report and check it against the cells. A real report lists every cell individually with measured capacity, internal resistance, voltage and serial number. It is far harder to fake than a code because it is long, specific, and you can verify it against the cells in front of you.
Read the full guide →What should a real EVE cell test report contain?
One row per cell, with measured capacity in Ah from an actual discharge, internal resistance in milliohms, open-circuit voltage at test time, and the cell serial. The numbers should vary slightly from cell to cell. Identical values down the whole column mean the report was typed rather than measured.
Read the full guide →How can I check the test report is genuine?
Three checks take two minutes. Look for natural variation in the numbers. Confirm there are as many rows as cells in the batch. Then pick a cell at random, read its serial, and find that exact row in the report. If you cannot match it, the report does not belong to those cells.
Read the full guide →Are the physical checks like the safety valve and B-mark still worth doing?
Yes, as a first pass. A missing safety valve, a ground-off mark or a code of the wrong length will catch a careless fake in seconds and costs nothing. Just do not treat passing them as proof — it means the cell is not an obvious fake, not that it is new.
Read the full guide →Should I test the cells myself even if I have the report?
Yes. The report tells you what the seller measured; your own bench tells you what arrived. Check resting voltage across every cell, internal resistance on a few against the report, and run one full capacity cycle if the order justifies it. Do it before the cells are welded into a pack.
Read the full guide →Do I need a stabilizer for a new inverter AC?
Only if your voltage goes outside the AC's rated range. Measure at the evening peak. If it falls below the range, fit a stabilizer: servo if voltage stays above 150V, SCR (from 95V) or IGBT (from 90V) for lower voltage.

Agar aap ke area mein voltage AC ki rated range se neeche ya upar jaata hai to haan. Pehle shaam ke waqt voltage check karein, phir us hisaab se stabilizer lein.

How to Tell EVE Cells Are Original: Ask for the Test Report
The QR code is no longer proof. Re-coding a cell is a cheap trade service, so a scannable code tells you almost nothing. The batch test report is the document that is actually hard to fake.
Do I Need a Stabilizer for My New Inverter, AC or Machine? Protecting New Equipment From Day One
New equipment has built-in protection, but it is designed to switch off, not to keep working on a bad line. Here is how to tell if your new inverter, AC or machine needs a stabilizer, and which type.
Low Voltage in My Factory: Servo, SCR or IGBT Stabilizer — Which Should I Choose?
End-of-line factory areas in Punjab and KPK see voltage fall far below 220V. Here is how servo, SCR and IGBT stabilizers compare, and which fits a whole factory versus one sensitive machine.
Why Does My Solar Inverter Trip on Low or High Voltage — and How Do I Fix It?
"AC input voltage out of range" means the grid voltage left the window your hybrid inverter accepts. Here is why it happens, when a stabilizer fixes it, and when it does not.
Machine or Motor Burnt Due to High Voltage? What to Do Now — and How to Stop It Happening Again
A burnt motor or control board after a voltage spike is painful. Here is what to do in the first hour, how to find the real cause, and what protection stops it next time.
Which Stabilizer Do I Need for a 50 kVA Factory or 3-Phase Load? (30–100 kVA Sizing in Plain Steps)
Sizing a three-phase stabilizer for a factory is five steps: add up the load, convert to kVA, allow for motor starting, add margin, and check the real voltage range. Worked example inside.
SCR vs Servo Stabilizer: Which One Should You Buy?
A servo stabilizer turns a motor to fix your voltage. An SCR stabilizer flips silicon switches. Here is what that difference means for your machines, your maintenance and your money.
IGBT vs Servo Stabilizer: Instant Correction vs a Turning Motor
An IGBT stabilizer fixes voltage instantly with nothing moving inside, and works down to 90V. A servo is proven, smooth and good value at large sizes. Here is when each one makes sense.
Solid-State Voltage Stabilizers: Why SCR and IGBT Are the Future
Every stabilizer with a moving part — a relay that clicks or a servo motor that turns — wears out. Solid-state stabilizers fix voltage with silicon instead. Here is how SCR and IGBT work, and why we think they are the future.
Servo Stabilizer Maintenance: Why Dust Is the Enemy, and a Simple Checklist
A servo stabilizer fights dust every day — the dust in the air, and the carbon dust its own brush makes. Here is a simple checklist that keeps one alive, and why SCR and IGBT stabilizers have nothing for dust to wear down.
Which Stabilizer for a Laser, CNC or Medical Machine?
A laser or an ultrasound machine costs lakhs. Protecting it with the wrong type of stabilizer is the most common mistake we see. Here is how to choose — by machine, by voltage and by size.
Servo Stabilizer Problems: Carbon Brush, Noise and Slow Correction
A servo stabilizer is a good machine with one weak point: it moves. Here are the faults we see most, what causes each one, what a fix involves — and when it makes more sense to go solid-state.
What Is an IGBT (Inverter) Voltage Stabilizer?
An IGBT stabilizer does not pick a tap or turn a motor. It builds the voltage you need, electronically, tens of thousands of times a second. Here is what that means in plain words.
What Is an SCR (Thyristor) Voltage Stabilizer?
SCR stands for silicon-controlled rectifier, also called a thyristor. In a stabilizer, it does the job a relay or a servo motor used to do — with nothing moving. Here is how it works, in plain words.
SCR vs IGBT Stabilizer: Which Solid-State Type Do You Need?
You have decided to skip the motor. Good. Now the real choice: SCR or IGBT. Both are solid-state, but they work differently, cost differently and suit different machines.
Which Voltage Stabilizer is Right for Your Home?
A simple guide to picking the right stabilizer size for your house — whether you have one AC, two ACs, or want to protect the whole home.
Lithium vs Lead-Acid for Load-Shedding: Which Is Worth It?
Lead-acid is cheaper today but dies in 2 years. Lithium (LFP) costs more up front and lasts 10+ years. Here's the honest math for a Pakistani home.
What Size Voltage Stabilizer Does My Home Need?
A simple sizing guide for Pakistani homes — by marla, by number of ACs, and by your actual load. Plus the one spec most people forget to check.
Will an Inverter Stabilizer Lower Your Electricity Bill?
Short answer: yes, a little — for the same reason an inverter AC saves power. Here is exactly how an inverter (IGBT) stabilizer uses less electricity.
Inverter vs Servo vs Relay Stabilizer: Which Is Best for Your Home?
There are four kinds of voltage stabilizer in Pakistan — relay (AVR), servo (SVC), SCR (thyristor) and inverter (IGBT). Here is the plain difference, and which one to buy.
