FOXWELL BT705 Plus Car Battery Tester 12V 24V Automotive, 100-2000CCA Battery Load Tester Digital Battery Analyzer Charging System Alternator Tester Cranking Checker for Car Heavy Duty Truck Marine

• Enhanced Version of BT705: More than a visual upgrade, BT705 Plus features a faster chip and smarter algorithm that boost testing speed by 30%. It also improves accuracy under testing conditions such as low battery charge or unstable alternator output. The upgraded color LCD ensures results are easy to read in any light. You can test battery, cranking, or charging systems individually—no set sequence required. With a 5.9" cable, even solo testing from the driver’s seat is simple. Designed for professionals and DIYers Note
• Why Does This Matter to You? A single battery failure could leave you stranded on the roadside, costing you hundreds in towing fees and lost wages while you wait helplessly for assistance—not to mention that gut-wrenching unease every time you turn the key. The BT705 Plus battery tester accurately diagnoses 12V/24V lead-acid batteries (1000–2000 CCA). It evaluates battery health (SOH/SOC) for replacement battery needs, tests starting systems (voltage/time/CCA) to prevent cold-start failures, and checks charging systems (no-load voltage/load voltage/ripple peaks) to detect alternator/regulator issues, helping you identify battery health issues before you're stranded
• What Ensures Data Accuracy? Our Foxwell battery tester employs advanced high-conductivity technology to deliver test results in seconds. Full-range mechanical connections ensure precise data retrieval, while the clip-on lead and clamp design maintain stable data transmission with minimal loss. This combination of features ensures the highest level of accuracy for reliable results
• Clear Display, Easy Diagnosis: The Foxwell battery analyzer features a high-contrast color LCD screen that delivers clearly visible test results in all lighting conditions, significantly improving data interpretation. Unlike traditional testers with complicated readouts, even beginners can instantly understand the five key diagnostic indicators—battery health status becomes immediately apparent
• Wide Compatibility, Instant Results: The automotive battery tester only takes a few minutes to perform a comprehensive battery health/cranking/charging test, enabling accurate assessment of battery condition before failures manifest. Ideal for auto repair shops, battery manufacturers/distributors, fleet managers, vehicle owners, and DIY enthusiasts. Compatible with all 12V/24V systems, including RVs, SUVs, ATVs, electric mowers, tractors, marine vessels, motorcycles, agricultural/construction equipment, buses, and heavy-duty truck trailers
• Note: (1) You need to enter the rated CCA value of the battery according to its labeling; (2) The car battery tester only tests storage batteries and does not support lithium batteries; (3) For in-vehicle testing
