With its smart design and advanced features, this charger is not only practical for professional use but also simple enough for everyday users.
At the core of the Justech charger is its 7-stage charging system, which ensures optimal performance and long battery life. These stages include desulfation, soft start, bulk charge, absorption, battery analysis, recondition, and trickle charge. Together, they provide a comprehensive process that revives weak or sulfated batteries, safely charges them to full capacity, and maintains that charge without risk of overcharging. Controlled by an automatic microprocessor, the charger intelligently detects the connected battery’s voltage and condition, seamlessly switching into the correct mode for maximum efficiency and protection. Once the battery is fully charged, it transitions into trickle mode to maintain energy levels, eliminating the worry of damage from continuous charging.
Safety is another defining strength of the Justech battery charger. Built with an automatic shutdown system and multiple protective mechanisms, it guards against short circuits, overcharging, overheating, over-voltage, reverse polarity, and over-time charging. This makes it a trustworthy option for both indoor and outdoor use, ensuring peace of mind no matter where or how you charge.
Practicality meets durability in its convenient and portable design. The Justech charger comes equipped with reinforced clamps and extended 80cm cables, making it easy to reach batteries even in tight engine compartments. A built-in cooling fan ensures efficient heat dissipation, keeping the charger quiet and reliable during operation. Its compact build, paired with a sturdy handle, makes it simple to carry and store, whether in a garage, workshop, or vehicle trunk.
With an adjustable output of 0–10A, this charger offers the flexibility needed for different battery sizes and conditions. It’s capable of operating within temperatures from 32°F to 104°F (0°C to 40°C), and with its built-in temperature sensor, it can adapt to changing environments for consistent performance. This makes it an indispensable tool for maintaining the health and longevity of your lead-acid batteries year-round.
Important to note, the Justech 8V Smart Charger is not compatible with lithium batteries and should not be used on frozen or completely dead batteries.
