How long can it last after a single charge? Does it depend on sunny weather? - Typical battery life: After full charge, it can be used for 3 to 6 months (in normal temperature environment), and some optimized models can last up to 1 year. - Energy mechanism: - Dual-mode power supply: Solar panels automatically replenish power (4 hours of daily sunlight is sufficient to maintain normal operation) + built-in rechargeable battery (mostly 6V/7AH). - Low-power design: Static current ≤ 3.5mA, working current ≤ 1A during lifting, reducing power loss. - Low-voltage alert: When the voltage is insufficient, a buzzer alarm or LED flashing will occur to prompt manual charging. 2. Can it work properly in extremely cold or rainy conditions? - Temperature adaptability: -40℃ to +55℃ (such as PL-03 type) or -20℃ to +55℃ (such as SJ-TG type), covering the climates of most regions around the world. - Waterproof grade: IP65 or above, fully sealed design, capable of withstanding rain erosion, snow water immersion, and even supports low-pressure water flushing. - Corrosion-resistant shell: Magnesium alloy or high-temperature die-cast metal body, rust-proof and moisture-proof. 3. What if the remote control fails? How far can it effectively control? - Remote control range: 15 - 50 meters (depending on the model, for example, the SJ-TG model is ≤ 15 meters, the PL-03 model is ≤ 50 meters). - Signal repair: -Adaptive learning function: The remote control can re-match itself (press the main board button or reset the power supply and follow the specified procedure), No need to return to the factory -Anti-interference design: 433 MHz radio frequency module, reducing conflicts with environmental signals. - Obstacle influence: Concrete walls or vehicle obstructions may shorten the effective range. It is recommended to ensure there are no large obstacles when installing. 4. Will it be damaged in a vehicle collision? What is its load-bearing capacity? - Anti-collision protection: - 180° bidirectional rocker arm: Automatically tilt and reset upon impact, triggering audible and visual alarms (≥ 90 dB), protecting the lock body and the vehicle. - Dual power failure protection: Automatically cuts off power supply after being blocked for more than 7 seconds or when the current exceeds 5A, preventing motor damage. - Compression strength: Static load-bearing capacity ≥ 2 tons (some models up to 5 tons), meeting the requirements for car/SUV crushing. 5. How to operate manually in case of power outage or malfunction? - Emergency device: - Turn the key to open the casing, then pull the mechanical wrench to manually raise or lower the rocker arm (such as SJ-TG type). - When the battery runs out, use the emergency-specific tool to rotate the emergency hole to unlock. - Anti-theft design: The installation screws are hidden inside the cover plate. Only with a special key can the cover be opened to prevent disassembly.
