About this item【Supports All 12V & 24V Batteries】Unlike conventional car battery testers, the BT410 battery tester is suitable for all 12V and 24V lead-acid and lithium batteries – including wet, AGM, gel, EFB and Li-ion batterie types. Ideal for cars, lorries, motorbikes, motorhomes, truck, RV, boats or solar systems. 【Professional 4-in-1 Test – Battery, Cranking, Charging & Alternator Test】The BT410 battery load tester provides a comprehensive health report on the vehicle battery: (1) Battery test – SOH, SOC, voltage, internal resistance, CCA; (2) Cranking test – voltage drop at the starter motor; (3) Charging test – alternator output, ripple, load/no-load test; (4) Alternator test – detection of overcharging/undercharging. No more guesswork – know exactly which component is faulty before carrying out repairs. 【Clear test Results – GOOD / RECHARGE / REPLACE + QR Code Report】No more decoding confusing numbers. The BT410 car battery health tester analyzes SOH, SOC, voltage, internal resistance, and CCA (100-2000), then gives a clear verdict: GOOD BATTERY, GOOD-RECHARGE, or REPLACE BATTERY. Scan the QR code after each test to save, share, or print a full professional report – perfect for DIYers or sharing with your mechanic. 【Reverse Polarity + Short-Circuit + Spark-Proof Protection】Worried about connecting the wrong way? The BT410 12v battery tester features reverse polarity protection, short-circuit protection, and spark-proof clamps – Even if you accidentally reverse the red and black clips, the tester will NOT damage your battery or itself. The robust ABS clamps provide a secure, corrosion-resistant grip for long-term, worry-free use. 【High-Precision Testing + 2.4" Color TFT Screen】Equipped with an advanced smart chip and conductance testing technology, the BT410 car battery and alternator tester delivers over 99.9% accuracy. The 2.4-inch colour display (320 x 240) supports contrast settings and a day/night mode – making it significantly easier to read than older LCD screens. You no longer need to squint, whether in direct sunlight or in a dark garage – all data is clearly visible. Supports 8 languages for users worldwide. 【Firmware Upgradable + Long Cable + 12-Month Warranty】The BT410 car battery checker supports free firmware updates, so it stays compatible with new battery standards for years. The 800mm (31.5-inch) cable easily reaches deep-set batteries. Operates reliably from -20°C to 70°C. Compact, portable, and backed by a 12-month warranty – a smart long-term investment for any DIYer or pro. |
