Car Battery Charger, 12V 6Amp Smart Automatic Battery Charger, Trickle Charger, Battery Maintainer and Battery Desulfator with Temperature Compensation Auto Stop and Color and Touch Screen Display

【Efficient Fully Automatic Charger】 This compact battery charger/restorer offers multiple modes to address various battery needs. It functions as a maintainer, trickle charger, and desulfurizer. Features include desulfurization, soft start, multi-stage charging, analysis, repair, float charging, pulse maintenance, and temperature compensation. Maintains and charges all 12V lithium batteries. Modes include Motorcycle, LiFePO4 Start-Stop, Automotive, and 14.6V Lithium. Compatible with lithium-ion and lead-acid batteries.

【Comprehensive Safety Protection】 Built with layered safety: Reverse connection triggers audible/visual warnings (alarm sounds, warning light illuminates). Automatically starts charging when correctly connected to power and battery. Includes automatic temperature monitoring and fault detection display. Features a durable, fire-retardant ABS casing for insulation, high-temperature resistance, impact protection, voltage stability, and longevity.

【Automatic Temperature Detection】Low temperatures increase battery internal resistance and reduce voltage, which can compromise charging performance. Conversely, warmer conditions elevate battery voltage. To address this, the charger automatically detects ambient temperature and selects the optimal charging mode: Winter Mode (activates below -10°C / 14°F) raises charging voltage, while Summer Mode (activates above 26°C / 80°F) reduces it. This autonomous adjustment ensures peak charging efficiency year-round without user intervention. An integrated cooling system with fan and aluminum heatsink regulates operating temperatures, prolonging the charger's service life.

【Color Smart Display】 The upgraded color screen clearly shows key data: voltage, current, temperature, charge time, full charge status, plus warnings for short-circuit, reverse connection, and maintenance needs. View battery voltage and charge level anytime. Switch display modes easily with a touch.

【Multi-Vehicle Compatibility】 Onboard charging mode remembers your last setting after power loss – simply reconnect to resume charging. This 12V/6A fast charger works on all 12V lead-acid batteries (AGM, GEL, SLA, Flooded) in cars, trucks, SUVs, motorcycles, lawn mowers, and boats. A practical household tool. *Note: Cannot charge completely dead (0V) batteries.
