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\u003c\/li\u003e\n\u003cli\u003eTEST 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\u003c\/li\u003e\n\u003cli\u003eSMART 8-STAGE CHARGING \u0026amp; 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\u003c\/li\u003e\n\u003cli\u003ePULSE 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\u003c\/li\u003e\n\u003cli\u003eFOLLOW 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\u003c\/li\u003e\n\u003cli\u003eTEMPERATURE COMPENSATION AND LOW-RIPPLE OUTPUT — Automatically adjusts voltage for hot or cold conditions to protect batteries from overcharging or undercharging.
