Battery Charger QOLTEC 52423 for AGM/GEL/STD batteries 6V/12V 1.5A

QOLTEC 52423 is a compact battery charger designed for safe charging and maintenance of lead-acid batteries including AGM, GEL and standard (STD) types. The unit supports both 6V and 12V battery systems and delivers a controlled 1.5A charging current. Its small form factor and straightforward operation make it suitable for motorcycles, scooters, small vehicles, UPS modules and a variety of leisure and power backup applications.

Advantages

The charger provides simple, reliable charging with automatic regulation of the charging current to protect battery health. Its compatibility with multiple battery chemistries (AGM, GEL, STD) and voltages (6V/12V) reduces the need for separate chargers. Compact size and light weight allow easy storage and transport, while the controlled 1.5A output supports both charging and trickle maintenance without overloading small batteries.

Suitable for

• Motorcycle and scooter batteries
• Small car and recreational vehicle batteries
• UPS modules and backup power units
• Garden equipment, lawn mowers and leisure devices
• Battery maintenance and long-term storage charging

How to use

Connect the charger to the mains supply, then attach the clamps or connectors to the battery terminals, observing correct polarity. Select the appropriate voltage setting (6V or 12V) if the unit requires manual selection, otherwise the charger will operate within its supported range. Start charging and monitor the battery periodically; once the charger indicates full charge or the charging current falls to maintenance levels, disconnect the unit following the manufacturer’s safety instructions. Use in a well-ventilated, dry area and avoid charging frozen or visibly damaged batteries.

Recommendations

For best results, use the charger for regular maintenance charging to prevent sulphation on lead-acid batteries. Do not leave the charger connected to severely damaged batteries. Ensure correct polarity when connecting clamps and store the charger in a dry place when not in use.
