Battery Charger QOLTEC 51919 90A 12V for LiFePO4 AGM GEL SLA

Description: Stable and safe energy source for all LiFePO4, AGM, GEL and SLA batteriesThe Monolith charger is designed to work seamlessly with a wide range of different types of batteries, including AGM, GEL, calcium, SLA and LiFePO4, providing them with a stable and safe energy source and a guarantee that the battery will remain in good condition throughout its lifetime.Discover the Unique Power of Smart Charging with the Monolith ChargerThe Monolith smart charger is an advanced device that will fully take care of your battery using an intelligent 3-stage charging process, adjusting the voltage and current according to the current state of the battery to ensure maximum battery life and performance.BULK Full recognition of the battery's needs and fast charging up to 80% of its capacity, while maintaining high voltage and maximum charging current.BOOST Absorption charging: stable voltage in the range of 14.1VDC - 14.8VDC, while the charging current is gradually reduced to protect the battery.FLOAT A gentle backup that allows the battery to reach full capacity, gradually lowering the voltage to 13.0VDC - 13.8VDC, and the charging current naturally drops to 0A when fully charged.Thanks to the LED indicator, you will always be up to date with the current stage of charging, and your battery will last longer and more efficiently!Optimal Performance, Long Battery Life and Minimisation of Costs and Energy LossesIntelligent 3-stage charging has many advantages, above all it can:- Ensure that the battery is fully and evenly charged, improving performance and battery life,- Prevent overheating, overcharging or damaging the battery, which improves battery safety and reliability,- Save energy and costs, as it recuces the loss of energy and time required to charge the battery.Trust our chargers - enjoy uninterrupted energy- Equipped with DIP-switch - this is the charger's component for changing the battery charging settings - it allows 7 different SW combinations to be set, we can adjust the charging mode according to the battery type you have, e.g. charging SLA / gel / AGM / flooded / calcium and LiFePO4 lead-acid batteries, as well as the constant voltage power supply mode,- 3-stage charging mode - provides much faster, efficient and full charging without the problem of voltage drops,- Durable aluminium housing - perfectly conductive and corrosion-resistant,- Built-in active cooling - automatically switches on when charging and protects the charger especially when charging heavily discharged batteries,- LED indication of charger operation,- Built-in fuse,- Features short-circuit, reverse polarity, overcharging and overheating protection,- Automatic shutdown at the end of the charging process - switches off charging mode and remains in sleep mode when the battery is charged,- Necessary wiring included.Advanced 90A smart charger - versatility and safety in one deviceIn designing the chargers, we focused primarily on safety and reliability.You can safely and quickly recharge your battery right now. The product has advanced safety features including protection against reverse polarity, overvoltage or overheating. While meeting international safety standards. For complete protection, the charger's inputs and outputs have been completely isolated.Advanced security features:UVP protection - Protection against under-voltage,SCP protection - is a short circuit protection,OVP protection - is the protection against too high output voltage,OCP protection - is the protection against too high current on the line,OTP security - is protection against overheating. | Type: Car | Filters / protection: Overheating | Filters / protection: Circuit | Filters / protection: Surge | Filters / protection: Voltage drop | Filters / protection: Reverse polarity | Filters / protection: Current too high | Batteries included: No | Accessories included: 1 x Battery charger 1 x Power cable 1 x Starter cable set 1 x Operating instructions | Color: Black | Color: Green | Other features: Battery type DIP switch setting DC charging Maintenance loading LiFePO4 SW0 14.7V0.1VDC 14.7V0.1VDC Flooded SW1 14.80.1VDC 13.8V0.1V DC Calcium SW2 15.0V0.1VDC 13.8V0.1V DC AGM SW3 14.6V0.1VDC 13.6V0.1V DC SLA SW4 14.4V0.1VDC 13.4V0.1V DC GEL SW5 14.2V0.1VDC 13.2V0.1V DC

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.

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.
