Waterproof 12V Solar Battery Charger & Maintainer for Car, Boat, RV and Trailer

This solar-powered battery maintainer and charger for 12V batteries is designed to help manage battery drain during all seasons. The product converts light energy from the sun into 12-volt DC electricity, which is then transported to the rechargeable batteries through the lead wire and connector, replacing the self-discharge of a battery in storage and preventing it from going dead. It can be used for a variety of applications, including cars, 4WD's, trucks, motorcycles, marine equipment, boats, farm equipment, or any other 12V battery-powered device.

The high-efficiency solar panel is capable of absorbing a wider spectrum of sunlight, and as long as there is sufficient sunlight available, the charger will generate an electrical current to trickle-charge the battery. The charger is equipped with the most advanced MPPT (Maximum Power Point Tracking) chip, which intelligently charges and fully protects the battery. The MPPT technology generates at least 20%-30% more power than traditional PWM (Pulse Width Modulation) systems. Additionally, the LED indicator helps users better understand the charging status at all times.

The LED indicator provides clear visual feedback on the charger's working status: - Blinking green: Sunshine is effective (not yet activated) - Blinking red: Working to charge the battery (activated) - Solid green: Battery is fully charged - Solid red: Error - Reversed polarity

The solar cells used in this charger are of high efficiency, offering at least 30% more power than competing products. The surface of the solar panel is covered with tempered solar glass, protecting the cells from snow, hail, dust, and other environmental factors. Additionally, the IP65 waterproof design allows the charger to withstand rain and snow, making it suitable for outdoor mounting without any maintenance concerns.

SUNER POWER, the brand behind this product, was founded by a team of technicians with at least 10 years of experience in the solar industry. The company's mission is to serve its customers by providing transparent, simple, and affordable solar power solutions for homes and businesses.

The key features of this solar battery charger include: - UltraSmart MPPT technology for high charging efficiency - Improved 3-stage charging algorithm for effective and safe battery charging - Multiple safety protections, including over-charge, over-discharge, and over-temperature - Wide compatibility with various 12V battery types, including lead-acid, gel, AGM, SLA, and LiFePO4 - Superior quality materials and construction for durability in extreme weather conditions
