Product Features

• 2-IN-1 BATTERY CHARGER & TESTER — Stop guessing what your battery needs. FOXWELL BC521 combines a 5A automatic battery charger and 12V battery tester, helping you check battery condition before charging. It also supports trickle charging, automatic maintenance, and pulse repair for complete 12V lead-acid battery care. Compatible with AGM, GEL, EFB, and flooded batteries in cars, SUVs, motorcycles, ATVs, RVs, boats, and lawn equipment
• TEST BEFORE YOU CHARGE OR REPLACE — When your vehicle is slow to start or will not start, do not guess whether the battery needs charging or replacement. This Foxwell battery tester checks CCA, voltage, internal resistance, SOH, SOC, cranking performance, and alternator output directly on the screen. Clear results help you identify a weak battery, low starting power, or a charging-system issue, then choose the right next step: charge, repair, or replace
• SMART 8-STAGE CHARGING & LONG-TERM MAINTENANCE — Ditch basic 2-3 stage chargers that force-feed batteries, cause overheating, and shorten lifespan. The 8-stage smart charger intelligently adjusts power to match your battery's condition, delivering precise, gentle charging that eliminates overcharging and overheating risks. It automatically switches to maintenance mode when full, keeping your vehicles ready to go for long-stored cars, pre-trip RVs, motorcycles, boats, and lawn equipment
• PULSE REPAIR WITH TEST RESULTS YOU CAN SEE — Test battery health before and after repair mode to see whether the battery is improving. Pulse repair helps reduce sulfation buildup in weak or long-stored 12V lead-acid batteries, while the built-in tester helps you decide whether to continue charging, repeat repair, or replace the battery. It cannot restore physically damaged or completely failed batteries
• FOLLOW THE SCREEN. CHARGE WITH PROTECTION — LCD screen, LED indicators, one-touch FN key control, and history records help you follow charging, testing, and battery status without guesswork. Built-in protection helps guard against reverse polarity, sparks, overheating, and overcharging. IP65-rated and flame-retardant for garage, driveway, workshop, and outdoor battery care. For 12V lead-acid batteries only; not for lithium, 6V, 24V, or jump starting
• TEMPERATURE COMPENSATION AND LOW-RIPPLE OUTPUT — Automatically adjusts voltage for hot or cold conditions to protect batteries from overcharging or undercharging. Low-ripple output delivers gentle charging to extend battery life and ensure safe, efficient charging with selectable 1A, 3A, or 5A currents
• COMPACT AND DURABLE DESIGN — Measures 190 x 74 x 58 mm with a 150 cm long cable, featuring flame-retardant housing and IP65 waterproof rating for safe use indoors or outdoors. Includes BC521 host, manual, and carrying case for convenient storage and portability
