FNIRSI BTM-24 multifunctional car battery tester

<h3>FNIRSI BTM-24 Multifunctional car battery tester</h3> <p>The FNIRSI BTM-24 is an advanced yet extremely easy-to-use 12V and 24V battery tester that replaces several diagnostic tools.
In a single measurement, you can check the voltage, starting current up to 2000A CCA, state of charge (SOC), state of health (SOH), internal resistance, and the correct operation of the alternator and charging system.
It&#x27;s a quick, clear answer to the question:<em>is the battery working properly, or is it nearing the end of its life</em>?</p> <p> <img alt="The FNIRSI battery tester stands next to a car battery, ready for quick diagnostics." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-1.jpg"/> </p><h3>No more guessing – you know before the battery fails</h3> <p>Dim lights, starting problems, or random electronic errors are the first warning signs.
FNIRSI BTM-24 eliminates guesswork – it clearly shows whether the problem is with the battery, alternator, or installation.
This allows you to avoid costly &quot;blind&quot; repairs and replacement of functional components.</p> <p> <img alt="The FNIRSI battery tester in the driver&#x27;s hand during an engine start test inside the car." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-2.jpg"/> </p><h3>Non-destructive battery health test – safe and reliable</h3> <p>The device uses a non-destructive diagnostic method, which means that the battery is not loaded during the test.
Simply select the battery standard and start the measurement with one click.
The result is presented in the form of a clear GOOD / CHARGE / BAD rating along with precise technical parameters – you know exactly what to do next.</p> <p> <img alt="The FNIRSI battery tester presented on various types of batteries in a workshop environment." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-3.jpg"/> </p><h3>Check engine cranking with one click</h3> <p>The One-Tap Cranking Test function records the voltage drop in real time during engine start-up.
The tester immediately informs you whether the start-up is within the normal range (>9.6V) or signals a problem.
It is an indispensable tool for diagnosing weak batteries and problems with the starting system.</p> <p> <img alt="The FNIRSI battery tester connected to the battery in the engine compartment during charging measurement." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-4.jpg"/> </p><h3>Real-time charging and alternator test while driving</h3> <p>The BTM-24 monitors dynamic, minimum, and maximum charging voltage, showing how the system responds to changes in engine speed and the activation of receivers.
A graphical voltage waveform graph allows you to assess the condition of the alternator, voltage regulator, and cables at a glance—no guesswork and no trip to the service station.</p> <p> <img alt="The FNIRSI battery tester shows the battery health result on a color screen." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-5.jpg"/> </p><h3>Full compatibility with batteries and vehicles</h3> <p>The tester supports 6 battery standards: CCA, EN, DIN, IEC, JIS, and GB, as well as AGM (flat and spiral), GEL, EFB, and classic lead-acid batteries.
It works well in passenger cars, motorcycles, ATVs, boats, delivery vehicles, trucks, company fleets, and golf carts – both inside and outside the vehicle.</p> <p> <img alt="The FNIRSI battery tester protected by reverse polarity protection on two batteries." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-6.jpg"/> </p><h3>Clear display and intuitive operation for everyone</h3> <p>The 2.4&quot; color TFT display with day and night modes ensures excellent readability in all conditions.
The simple menu guides the user step by step, so the device can be easily used by mechanics, novice drivers, and used car buyers alike.</p> <p> <img alt="The FNIRSI battery tester with a display in day and night mode against the background of a road and cars." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-7.jpg"/> </p><h3>Maximum safety at work</h3> <p>Robust, insulated crocodile clips with a wide grip range ensure a secure connection to the terminals.
Built-in reverse polarity and overvoltage protection protects the battery, vehicle electronics, and the device itself – test without stress or risk.</p> <p> <img alt="The FNIRSI battery tester is used by a mechanic during a battery check in a workshop." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-8.jpg"/> </p><h3>Well-thought-out design and ready-to-use set</h3> <p>The FNIRSI BTM-24 has an integrated, tear-resistant cable, 61-centimeter clamps, a foldable stand, and a hanging hole.
The set includes a tester, instructions, a data cable, and a practical case, so the device is always safe, mobile, and ready to use.</p> <p> <img alt="The FNIRSI battery tester is based on a battery with solid clamps in a professional garage." border="0" src="https://assets.innpro.pl/19553/26060/Wielofunkcyjny-tester-akumulatorow-samochodowych-FNIRSI-BTM-24-lifestyle-9.jpg"/> </p><h3>Who is the FNIRSI BTM-24 for?</h3> <p>It is the perfect tool for mechanics, workshops, DIY enthusiasts, new drivers, company fleets, and used car buyers.
