Product information

Description

QOLTEC 51918 is a 12V battery charger with an 80A maximum charging current, engineered to charge a range of 12V battery chemistries including LiFePO4, AGM, GEL and SLA. Designed for use with vehicle, marine and standby power systems, the charger delivers controlled charging profiles that align with each battery type’s voltage and charging requirements. The unit supports fast bulk charging followed by regulated absorption and maintenance stages to ensure reliable battery readiness and extended service life when used according to manufacturer guidelines.

Advantages

The charger offers multi-chemistry compatibility, enabling safe charging of LiFePO4, AGM, GEL and SLA batteries with tailored charge algorithms. High charging current capability (up to 80A) reduces charge time for large capacity batteries while regulated output and stage-based charging protect batteries from overcharge and overheating. The device is suitable for continuous service in applications that require maintained battery voltage and includes features that support stable, consistent charging under varying load conditions.

Suitable for

  • Charging 12V LiFePO4 batteries in vehicles and boats
  • Recharging AGM and GEL batteries used in automotive and marine starting and auxiliary systems
  • Maintaining SLA/lead-acid batteries in backup power and UPS systems
  • Rapid charging of high-capacity batteries for fleet and service vehicle applications

Key specifications

  • Nominal output voltage: 12 volts DC
  • Maximum charging current: 80 amperes
  • Supported battery chemistries: LiFePO4, AGM, GEL, SLA (lead-acid)
  • Multi-stage charging: bulk, absorption, float/maintenance
  • Suitable ambient operating conditions for automotive and marine use (refer to manufacturer for exact ranges)

How to use

Connect the charger to the battery following the polarity markings and the manufacturer’s safety instructions. Select the appropriate battery chemistry or charge program before initiating charging to ensure the correct voltage and current profile are applied. Monitor charging progress using the charger’s indicators or display; allow the charger to complete its programmed stages so the battery reaches full charge and transitions to maintenance mode. Disconnect the charger after the maintenance or float stage if long-term connection is not required.

Usage recommendations

Use suitable cable cross-sections and secure connections to handle the 80A charging current. Verify battery condition before charging; do not attempt to charge severely damaged or leaking batteries. For LiFePO4 batteries, ensure the battery management system is compatible with external charging and that correct charge voltages are selected. When using in marine or automotive environments, protect the charger from water exposure and excessive vibration according to installation guidelines.
