4-in-1 Versatile Battery Tool - Upgrade your garage with the FOXWELL BC521—a charger, tester, desulfator, and maintainer all packed into one compact device. Compatible with 12V lead-acid batteries (AGM, GEL, EFB, Flooded), it not only recharges but also diagnoses, restores, and maintains your battery, ensuring your car, motorcycle, RV, or boat always starts reliably after long idle periods.
8-Stage Smart Charging - Unlike standard trickle chargers, this automotive battery charger uses 8 intelligent stages including Desulfation, Float, and Pulse, to optimize battery performance. Selectable 1A/3A/5A current lets you set the ideal charging speed for any battery. Built-in temperature compensation and stable current control prevent battery wear, overheating, or overcharging, helping your battery last longer than ever before.
Real-Time Battery Diagnostics & Accuracy - More than just a charger, it works as a professional battery tester with 99.9% accuracy. Instantly check voltage, SOH (State of Health), internal resistance, cranking performance, and alternator status. Get clear, real-time results to know if your battery needs charge, repair or replacement, avoid sudden breakdowns, and drive with peace of mind and confidence.
Revive & Maintain Batteries - Don't replace your dead battery too soon. Restore sulfated batteries with Maintainer Mode, recovering capacity in deeply discharged batteries and extending lifespan to save on premature replacements. Once fully charged, it automatically switches to Unattended Mode, keeping batteries at optimal voltage for weeks or months—without unplugging. Ideal for cars, RVs, motorcycles, and boats left in long-term storage.
Built-In Safety & Outdoor Durability - Your safety comes first. With 6 safeguards—over-voltage, over-current, overheating, reverse polarity, overcharge, and over-discharge—your battery stays fully protected. Flame-retardant housing and IP65 waterproofing ensure safe use indoors or outdoors. Temperature compensation adjusts voltage for hot or cold weather, keeping your battery healthy year-round.
Quick FN Hotkey & History Tracking - Designed for convenience, the backlit LCD and LED indicators clearly show charging and test results. One-touch FN hotkey recalls your last charging mode (Quick Charging) or runs a Battery Test instantly, saving time on repeated tasks. Review past charging and test history to monitor performance trends over time—ideal for DIY users and professionals alike.
