Voltage of every block
Block by block, plus the gap between the highest and lowest. That is the real measure of battery condition — a single "OK" tells you nothing.
Hybrid battery test in Warsaw — before you buy, on site
Buying a used hybrid in Warsaw or around it? I come to wherever the car is — a used-car lot, a car park or the seller's home — and read the voltages of all the battery blocks, the spread between them and the hybrid system's error history. You get numbers before you pay.

Why it matters
Why it makes particular sense in Warsaw
Lots of hybrids, high mileage, little time to verify.
In and around Warsaw there are a great many used Toyota hybrids, including ones that earlier worked as taxis or company cars — and such cars have high mileage. Sometimes an advert shows a car that looks good while its battery is already near the end.
No errors on the scanner does not mean the battery is healthy: the control unit only raises an error after a threshold is crossed. The battery condition is shown by the voltage of every block separately and the spread between the weakest and the strongest block — that is what I read.
You do not have to go anywhere or wait: I come to the used-car lot or the seller, do the test on site and explain in plain language what it means for the price.
- A car that was a taxi or fleet car — high mileage, heavy use
- A used-car lot with several hybrids — worth checking the one you are actually buying
- The seller says the battery is "like new" — the numbers will confirm it or not
- A car with a reconditioned battery — you can see whether the blocks are matched
Scope
What exactly I read
I connect to the hybrid system control unit, not just the OBD socket for a list of fault codes.
Behaviour under load
How the blocks hold voltage while charging and discharging. A weak block shows itself in use, not at standstill.
History and counters
Faults stored in the hybrid control unit, including cleared ones, plus system counters. You can see whether memory was wiped before the sale.
Battery cooling
Fan operation and how clear the cooling ducts are. Blocked cooling kills a battery faster than mileage does.
The rest of the hybrid system
Inverter, DC/DC converter and the 12 V battery. Not every "battery failure" is the battery — sometimes it is a cheaper fault next to it.
All other control units
A full scan of the remaining modules comes with it: engine, ABS, airbags, electrics. Already included in the visit.
From our work
What the test actually looks like
A 2018 Toyota Auris Hybrid checked before purchase: voltage of each of the 14 blocks read separately. The spread stayed under 0.15 V even under load and there were no faults — the battery was in very good shape. That is the kind of result you can put in front of a seller.

Where I go in Warsaw and around
Warsaw within 50 km of Grodzisk Mazowiecki — preferably the western districts (Ursus, Włochy, Ochota, Bemowo, Wola) and the towns next to Warsaw: Piastów, Pruszków, Ożarów Mazowiecki, Raszyn, Nadarzyn. The call-out is 150 zł across the whole area.
If the car is further away, call me — I will say whether I can come. Other hybrid makes (for example Honda, Hyundai, Kia, Ford) I can try to check, but what I can read depends on the model — I tell you plainly by phone what I will be able to read before we agree.
Prices
What it costs
The price is simple: call-out plus work. I quote the total by phone before I set off.
| Item | Price | Notes |
|---|---|---|
| Hybrid battery test | 250 zł | Fixed service price |
| Call-out | 150 zł | Within 50 km of Grodzisk Mazowiecki |
| Computer diagnostics | from 80 zł | Reading fault codes and control-unit data |
| Weekend work | +20% | Saturday and Sunday |
Parts are not included in the labour price. I quote before I set off — never after the fact.
How it goes
What it looks like
From the phone call to a decision is usually one day.
Phone call
You tell me the model, year and where the car is. I quote the price straight away and what I can read on that particular car.
Call-out
I come to the address — a used-car lot, a car park, the seller's home. Weekends too.
Readout
Connection to the hybrid system control unit, reading the blocks, measurements under load and a full scan of the remaining modules.
Conversation and result
I explain the result in plain language: what is normal, what deviates and what it means for the car price. You get the result in writing, with numbers.
Questions
Common questions
Question not here? Call me — I will answer straight away.
250 zł for the test, plus a 150 zł call-out within 50 km of Grodzisk Mazowiecki. I give the total by phone before I set off.
Yes, I come to wherever the car is: a used-car lot, a car park, the seller's address — anywhere in Warsaw within 50 km, preferably in the west. The car does not have to be moved anywhere.
Usually 40–60 minutes, including a full scan of the other control units and a walk-through of the result.
It does, because such cars have high mileage and heavy use. The test shows the condition of the battery blocks here and now — whatever the car's history. It is also worth asking the seller what the car was used for.
I have full block-level battery data on Toyota and Lexus. Other makes I can try to check — the scope depends on model and year, and I tell you by phone what I will read before we agree.
Yes. You get the result written down with concrete values — you can show it to the seller when negotiating.
Yes, I need their permission to connect to the car — and an honest seller does not refuse. A refusal is information in itself.
