· Why can't lead-acid batteries be charged with fast chargers?

The reasons why lead-acid batteries are usually not suitable for using fast charging chargers are as follows:lead-acid batteryBattery structure and chemical characteristics: Lead acid batteries are a mature technology, but their charging and discharging rates are relatively slow. They are typically deep cycle batteries designed for long-term use at low discharge rates. Rapid charging may cause uncontrolled internal reactions in the battery, leading to issues such as overheating, gas generation, and electrolyte loss.Electrolyte loss: Rapid charging may cause the moisture in the electrolyte to be decomposed into hydrogen and oxygen, resulting in electrolyte loss and affecting battery performance and lifespan.Temperature control: During rapid charging, the battery will generate heat, while lead-acid batteries are sensitive to high temperatures. Excessive temperature may cause battery damage or failure.Safety considerations: Rapid charging increases the risk of battery overheating and ove...

· What is the difference between chargers with and without PFC?

PFC (Power Factor Correction) is a technology used to improve the efficiency of power systems. The power factor of a power system refers to the phase difference between current and voltage. An ideal power factor close to 1 or 100% means that current and voltage are completely synchronized. Power factor correction is mainly used to improve synchronization, reduce energy loss, and enhance the efficiency of electrical equipment. Whether the charger is equipped with PFC has a significant difference in its performance and impact on the power grid.180W Battery ChargerCharger without PFCLow power factor: This type of charger usually has a lower power factor, which may be between 0.5 and 0.7. Low power factor means there is a significant phase difference between current and voltage, leading to insufficient energy utilization.Low energy efficiency: Due to low power factor, these devices may result in higher energy loss and lower efficiency.Grid load: Equipment with low power factor can increas...

· The difference between the direct charging function and the recharge function of smart chargers

Smart chargers typically have multiple functions, including direct charging and recharge, which play different roles during the charging process.Direct charging function:The direct charging function refers to the charger transferring electrical energy directly to the battery or charging device, with the main purpose of charging. During the direct charging process, the charger adjusts the current and voltage to the appropriate level to ensure safe and efficient charging of the device.The direct charging function is usually used to fully charge or maintain the battery or device for later use. This feature is suitable for ordinary charging scenarios, such as mobile phones, laptops, electric vehicles, etc.Recharge function:The recharge function refers to the charger's ability to monitor the battery status and automatically adjust the charging process after the battery or device is fully charged, in order to prevent overcharging, float charging, or other situations that may affect battery...

· What is the difference between waterproof grades IP65 and IP67?

The waterproof levels of IP65 and IP67 are both protection level standards set by the International Electrotechnical Commission (IEC), used to describe the protective ability of equipment against solid objects and liquids. These levels are represented by two digits, with the first digit indicating the level of protection against solid objects (such as dust) and the second digit indicating the level of protection against liquids (mainly water).360W Waterproof ChargerFor IP65 and IP67, the first digit of both protection levels is 6, indicating that the equipment is completely dustproof, meaning no dust will enter the interior of the equipment.The main difference between the two lies in the second digit, which is the level of protection against liquids:IP65: Protection level 5 indicates that the device can prevent the intrusion of water flow. Specifically, IP65 rated equipment can withstand low-pressure water jet from any direction, suitable for some outdoor environments, but not suitabl...
