NOCO GENIUS2 6V/12V 40A Smart Battery Charger & Desulfator

Compatible with 6V and 12V batteries. Performs maintenance regardless of amp-hour rating and is compatible with flooded (wet) batteries, gel, MF, AGM, EFB (lead-acid) and Li‑ion batteries. Charges batteries up to 40 Ah at 6V/12V, performs maintenance regardless of amp value and can restore battery condition. Suitable for a wide range of vehicles: cars, motorcycles, trucks, boats, tractors, lawn mowers, ATVs, SUVs, caravans, classic cars and more. Charges and maintains batteries and helps recover dead cells. Can charge batteries that have fallen below 1 V. For batteries reduced to zero volts, use Force Mode to disable automatic safety and charge manually. Charges up to twice as fast as ordinary chargers. Smaller and higher performing than typical chargers: stated as 97% smaller and 98% superior performance (manufacturer claim). Repairs damaged batteries, renews battery cells, dissolves sulfation/oxidation on plates and prevents energy loss. Integrated AI analyzes the battery automatically and selects the optimal charge settings based on battery type, capacity and state of discharge. Provides professional battery charging with a 9‑stage charge and maintenance program. Automatic charge stages: 1. Analysis, 2. Diagnosis, 3. Recovery/Repair, 4. Initial charge, 5. Bulk charge, 6. Battery equalization, 7. Optimization, 8. Maintenance charge, 9. Desulfation. AI continuously monitors battery condition for effective, trouble‑free charging and manages charging to minimize energy consumption. Desulfator function can be connected directly to new or old batteries to reduce sulfation and oxidation, repair battery plates, restore full capacity, extend battery life and prevent damaged batteries from harming the vehicle electrical system. Automatically detects and helps remove sulfate and acid layering to recover battery performance.
