Automotive battery charger that maintains and revives 6V and 12V lead-acid and lithium batteries. Keep vehicles ready with confidence, knowing long-term battery health is supported by precision maintenance and desulfation using the NOCO Genius2 Charger. Is a compact 2A maintainer the right choice for users who need slow, safe upkeep rather than rapid top-ups?
⚡ At a Glance
- • Charging Capability: Smart 2A charging for 6V and 12V lead-acid and LiFePO4 batteries
- • Best for: Owners of cars, motorcycles, boats and leisure vehicles needing maintenance and battery recovery
- • Not ideal for: Users who need rapid high-amp charging for large commercial or truck batteries
Compact 2A charger supports 6V and 12V lead-acid and LiFePO4 batteries. Designed for maintenance, recovery and safe long-term connection.
Accurate temperature-adjusted charging – thanks to an integrated thermal sensor
Integrated thermal sensor monitors ambient temperature and adjusts charge voltage and current to prevent overcharging in hot conditions and undercharging in cold conditions.
Consistent, temperature-aware charging helps maintain battery health through seasonal changes, reducing the risk of damage from incorrect voltages.
Recovery of deeply discharged batteries – with Force Mode and low-voltage charging
Charges from as low as 1 volt under normal operation, and Force Mode initiates controlled charging from zero volts to revive completely depleted batteries.
Many flat or neglected batteries can be recovered without replacement, saving time and avoiding unnecessary battery purchases.
Reverse sulphation to extend battery life – thanks to precision pulse desulfation
Precision pulse charging detects sulphation and acid stratification, applying controlled pulse currents to break down sulphate deposits and restore more even acid distribution.
Improved battery capacity and starting performance result, extending service life and reducing the frequency of replacements.
