NOCO Genius smart battery chargers are some of the safest and most advanced on the market. One of our best, the G3500 3. 5 Amp is designed to charge 6-volt and 12-volt lead-acid and lithium-ion batteries up to 120Ah. It can also effectively maintain automotive, marine, RV, power sport, lawn & garden and deep-cycle batteries. It charges 2x faster than ordinary battery chargers, can repair damaged batteries and is designed for use with micro-hybrid start-stop vehicles and CANBUS electrical systems. Guided by an onboard microcomputer, the G3500 monitors battery activity for safe and efficient charging, automatically minimizes energy consumption and provides redundant levels of safety protection, including spark-proof technology, as well as reverse polarity and overcharge protection. It can remain safely connected 24/7, while its streamlined design makes it ultra-compact, portable, and incredibly lightweight. The G3500 features external mounting holes and a rubberized base that avoids surface slipping and scratches, while remaining impact, UV and water-resistant (IP65). Intuitive LED indicators provide visual state-of-charge feedback and diagnostic information, even when in maintenance mode. Designed for use on 120-volt 50-60Hz electrical systems, the G3500 includes both X-Connect battery clamps with integrated eyelet terminals, as well as a 5-year limited .
