## Long description

QOLTEC 12V 5A rectifier battery charger is designed for charging and maintaining 12V AGM and GEL lead-acid batteries. The compact rectifier format delivers a stable 5A charging current suitable for service, standby and maintenance applications. Intended for use in workshops, garages and vehicle installations, this charger supports regular battery charging cycles and float maintenance to help extend battery life and ensure reliable engine starts or backup power availability.
Advantages
The charger provides a consistent 5A output with voltage regulation optimized for AGM and GEL chemistry, reducing overcharge risk and supporting safe long-term float use. Its rectifier design offers compact footprint and simple installation for fixed or semi-permanent setups. Built to deliver steady current for both charging and maintenance, the unit helps maintain battery capacity and readiness without complex user input.
Suitable for
 Charging and maintaining 12V AGM batteries
 Charging and maintaining 12V GEL batteries
 Workshop and garage battery service
 Vehicle installations requiring a fixed charger or battery maintainer
 Backup power systems and standby battery upkeep
Key specifications
 Output voltage: 12 V DC
 Maximum charging current: 5 A
 Battery types supported: sealed lead-acid (AGM), gel
 Operation modes: charge and float/maintenance
 Form factor: rectifier/compact power unit for fixed mounting
 Typical installation locations: workshop, garage, vehicle compartment
How to use
Connect the charger to the battery following standard polarity: positive to positive and negative to negative. Ensure the power supply is disconnected before connecting to prevent sparks. Once connected, apply mains power and allow the charger to run through its charging cycle until the float stage is reached; the device supplies a controlled 5A current during bulk charging and reduces to a maintenance level when the battery is fully charged. For routine maintenance, the charger can remain connected for extended periods in float mode to keep the battery topped up.
Usage recommendations
Use the charger in a dry, ventilated location and avoid covering the unit during operation. Verify compatibility with the battery manufacturer’s recommended charging voltage for AGM and GEL types. Periodically inspect wiring and connections for corrosion or damage and disconnect mains power before performing any maintenance on the charger or battery.
