Genius Automatic Portable Battery Charger 10 Amp, 6V/12V (GENIUS10)

The Genius10 is a 10-amp portable battery charger and maintainer. It's designed for all types of 6-volt/12-volt lead-acid batteries, including flooded, gel, AGM and other maintenance-free batteries.

It features their all-new hyper-density technology making it the most compact, lightweight and energy efficient battery charger on the market, plus an integrated thermal sensor for improved battery life.

• Powerful, smart charger: The GENIUS10 delivers a full 10-amp charging current for both 6 V and 12 V systems—ideal for automotive, marine, RV, powersports, lawn & garden, and deep-cycle battery applications.
• Multi-chemistry, multi-battery type support: Compatible with flooded (wet) lead-acid, gel, AGM, maintenance-free, enhanced flooded batteries (EFB), and even lithium-ion battery systems—making it a versatile solution across vehicle types and storage scenarios.
• Compact hyper-density design: Built using next-generation high-frequency switch-mode technology, the unit is significantly smaller and lighter than earlier models—offering advanced performance in a space-saving footprint.
• Built-in thermal sensor for precision charging: The integrated ambient-temperature sensor adjusts charging parameters automatically to compensate for hot or cold environments. Optimizes battery life by preventing under-charging in cold or over-charging in heat.
• Desulfation and battery repair mode: The GENIUS10 detects sulfation/acid-stratification in neglected or weak batteries and initiates automatic repair cycles to restore performance and extend battery life.
• Dead-battery recovery: Capable of charging deeply discharged batteries down to as low as 1 volt in standard mode, and in “Force” mode even down to 0 V—helping recover seemingly dead batteries instead of replacing them right away.
• Continuous maintenance mode & safe for long-term storage: Once the battery is fully charged, the charger automatically switches into maintenance (“float”) mode so you can leave it connected indefinitely without risk of overcharging. Excellent for off-season maintenance of vehicles, boats, RVs, and equipment.
• Robust build and safety features: Features include spark-proof connections, reverse-polarity protection, short-circuit protection, open-circuit and overheating protection, and IP65-rated housing for dust and water-jet resistance.
• Wide operating range: Works from line voltages 120-240 VAC (50-60 Hz) with high efficiency (~87%). Supports operating temperatures from –4 °F (–20 °C) up to 104 °F (40 °C); storage range down to –22 °F and up to 140 °F for durability.
• Ideal for a huge variety of uses: Whether you’re maintaining a classic car, charging an ATV, keeping a boat battery healthy during winter storage, or topping off an RV’s deep-cycle battery between trips, this charger brings flexibility and reliability. Automotive, marine, powersport, lawn & garden, off-road — you name it.

What’s included in the box: The GENIUS10 charger unit with interchangeable connector, battery clamps with integrated eyelets (M10), mounting bracket and strap, two self-tapping screws, plus safety & warranty documentation (3-year limited warranty).

By choosing the GENIUS10, you’re getting more than just a typical battery charger—this is a smart 10 amp battery charger and maintainer optimized for 6 V/12 V lead-acid and lithium batteries, with advanced features like thermal compensation, desulfation/repair mode, and auto maintenance mode.
