## Summary description

Intelligent QOLTEC microprocessor charger provides 12V output at 5A and is designed as a rectifier for AGM, GEL and SLA lead-acid batteries. The device uses a 6-stage charging algorithm to maintain battery health, support fast and maintenance charging, and reduce overcharge risk. Suitable for automotive, backup and leisure battery maintenance and periodic recharging.

## Long description

The QOLTEC Intelligent microprocessor charger delivers a regulated 12V output at 5A and is designed as a rectifier for AGM, GEL and SLA lead-acid batteries. Using a six-stage charging algorithm, the charger monitors battery condition and adjusts charging current and voltage to provide bulk charging, absorption, float maintenance and desulfation where needed. The compact unit is intended for regular maintenance, periodic recharging and long-term float connection for automotive, backup and leisure battery applications.
Advantages
The microprocessor control enables adaptive charging profiles that help extend battery life and reduce the risk of overcharging. The six-stage algorithm provides fast initial charging followed by controlled absorption and safe float maintenance. The charger supports multiple lead-acid battery types (AGM, GEL, SLA), delivers stable voltage regulation under varying load conditions and includes protections against reverse polarity, short circuit and overtemperature. Its stable 12V/5A output suits both replenishing depleted batteries and maintaining batteries in standby systems.
Suitable for
Automotive 12V lead-acid batteries (starter batteries) requiring maintenance charging
Backup power batteries in UPS and alarm systems that need float maintenance
Leisure and marine batteries used seasonally or stored between uses
Workshop or garage use for periodic recharging of 12V AGM, GEL or SLA batteries
Key specifications
Output voltage: 12 volts DC
Maximum output current: 5 amperes
Charging algorithm: six-stage microprocessor-controlled charging
Supported battery types: AGM, GEL, SLA (sealed lead-acid)
Functions: bulk, absorption, float maintenance, desulfation and controlled charge termination
Protections: reverse polarity, short-circuit protection and thermal protection
Intended operation modes: maintenance/standby float and active recharge
How to use
Connect the charger to the battery with correct polarity while the charger is switched off; then apply mains power to start the automatic charging cycle. The device will analyse battery state and execute the appropriate stages of the six-step algorithm, progressing from bulk charge to absorption and finally to float maintenance. Monitor charging status using the charger's status indicators and disconnect mains power before removing leads if required by the charger model instructions. For long-term connection in float mode, verify ambient temperature and ventilation to avoid thermal stress.
Usage recommendations
Use the charger in a dry, well-ventilated area and avoid charging frozen or heavily sulfated batteries without prior inspection. For optimal battery life, select this charger for routine maintenance of 12V AGM, GEL and SLA batteries and avoid prolonged high-temperature exposure. Regularly inspect terminals and wiring for corrosion and secure connections during charging.
