## Long description

Wired battery charger QOLTEC 51919 delivers 12V output with up to 90A charging current and supports LiFePO4, AGM, GEL and SLA battery chemistries. It is designed for charging and maintaining 12V stationary and vehicle batteries, offering a high-current mode for faster recharge and a maintenance mode for long-term battery care. The charger is suitable for use in workshops, garages and fleet service environments where reliable replenishment of 12V battery capacity is required.
Advantages
The charger provides flexible charging for several common battery types — LiFePO4, AGM, GEL and SLA — enabling a single device to serve multiple battery applications. With a maximum charging current of 90A at 12V it supports rapid recharging of larger capacity batteries while also offering modes intended for safe battery maintenance. The wired connection and robust current output make it suitable for professional use in service garages and fleet depots, and its design focuses on consistent voltage delivery and controlled current to protect battery lifespan.
Suitable for
 Charging and maintaining 12V LiFePO4 batteries
 Charging AGM and GEL lead-acid batteries in vehicles and stationary systems

 Workshop, garage and fleet battery service and maintenance
Key specifications
 Output voltage: 12 V nominal
 Maximum charging current: up to 90 A
 Supported battery chemistries: LiFePO4, AGM, GEL, SLA
 Modes: high-current charge and maintenance/float charge
 Connection type: wired output leads for direct battery connection
How to use
Connect the charger’s output leads to the battery terminals following correct polarity: positive to positive and negative to negative. Select the appropriate battery chemistry setting (LiFePO4, AGM, GEL or SLA) and choose a charging mode suitable for the battery’s state — high-current mode for faster recharge of depleted batteries, or maintenance/float mode for long-term upkeep. Monitor charge progress and battery temperature during high-current charging sessions and follow vehicle or battery manufacturer recommendations for charging rates and endpoint voltages.
Usage recommendations
Use the charger in well-ventilated areas and ensure connections are secure before switching on. For regular maintenance, employ the lower-current or float mode to avoid overcharging; reserve the 90A high-current mode for situations that require faster replenishment of large-capacity 12V batteries. Always verify the battery type and state prior to charging and follow safety guidance for lead-acid and LiFePO4 batteries.
