MULTI-VOLTAGE, MULTI-CHEMISTRY, MULTI-BATTERY TYPE.
DO MORE WITH ONE CHARGER.
Effortlessly charge multiple battery voltages (6-Volt and 12-volt lead-acid and lithium-ion batteries) chemistries (Flooded, gel, maintenance-free and AGM batteries) and types (Starter, deep-cycle, marine, powersport and more).
WORRY FREE YEAR-ROUND CHARGING.
COMPLETELY AUTOMATIC.
Completely automatic from start to finish, no technical knowledge required. Genius will safely charge any battery. Detect damaged batteries and intuitively repair them. And actively monitor for long-term battery maintenance and extend battery life. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.
THERMAL COMPENSATION. SMART DIAGNOSTICS
incredibly SMART.
An integrated thermal sensor monitors fluctuations in the temperature and automatically adjusts the charging cycle to provide a more accurate and fully charged battery. Smart indicators quickly detect when the battery charger is connected in reverse polarity, connected to an incompatible battery, or if the battery is failing.
THE NEXT GENERATION OF CHARGING.
MORE POWERFUL. MORE COMPACT.
Compact, yet powerful battery charger, welcome to the all-new Genius series. Improved charging with more performance and more automation than ever before. A mix of electrical engineering and industrial design pack a powerful battery charger into a tiny footprint. The new GENIUS5 is 34% smaller with 65% more power compared to the previous G3500.
DOWN TO ZERO VOLTS.
CHARGE DEAD BATTERIES.
The all-new start-voltage sensor allows the Genius to detect and charge dead batteries as low as 1-volt. For extremely dead batteries lower than 1-volt, manually turn on force mode to detect and charge batteries all the way down to zero volts.
DOWN TO ZERO VOLTS.
GENIUS CHARGE TIMES.
Approximate charge times at 50% depth of discharge.
