3-in-1 SOLUTION: BT521 combines charger, tester and maintainer into one intelligent device. It delivers more performance than traditional chargers or testers, while freeing up over 75% of your toolbox space and cutting battery-related task time by 80%. Plus, it saves you more than 240+ in equipment costs. You’re not just buying a tool—you’re investing in faster and more efficient work
BATTERY CHARGING: Smarter than just a Charger, BT521 Equipped with 8-stage smart charging technology to revive deeply discharged batteries down to 2V and restore batteries affected by sulfation or long-term storage. It delivers a stable output with low ripple and minimal heat, which helps reduce wear on the battery and extend its overall lifespan. Restore the old, strengthen the new
BATTERY TESTING: Never get stranded again. Its smart chip and rugged clamps deliver >99.6% accuracy. Instantly check battery health, voltage, current and cranking with one tap. Detect hidden issues early to avoid unexpected breakdowns, save on towing, repairs and premature battery replacement
BATTERY MAINTENANCE: Most chargers stop at charging, but BT521 goes further. Pulse technology restores up to 90% lost capacity and clears buildup during charging to help prevent long-term damage. Regular use can extend battery life 2-3 times and reduce replacement costs(Note:Check once a year)
SAFETY PROTECTION: Built-in temperature control chip auto-adjusts charging (-25℃-75℃) to prevent overheating in summer and undercharge in winter, 5-way electrical safeguards and durable flame-retardant design work together to prevent reverse-connection, over-voltage, over-current, short-circuit, overheating, even in harsh conditions
USABILITY: Plug-and-play design eliminates pre-calibration, just connect to power and clamp electrodes for 3-second auto-start. The LCD screen tracks real-time voltage, charging progress, and battery health with intuitive visuals. Streamlined operation meets robust protection, optimizing charging efficiency and extending battery lifespan
COMPATIBILITY: Designed for ALL 12V lead-acid batteries: AGM, GEL, SLA, Flooded, Deep Cycle, Marine and so on. Supports cars, motorcycles, boats, ATVs, SUVs, RVs, trailers, lawnmowers, mopeds, classic cars, and more. Whether you're testing or charging—it’s the one tool for every job
