Not universal   Lithium battery chargers and lead-acid battery chargers are not universal.   Lithium batteries and lead-acid batteries are different types of batteries, and their charging principles differ. Lithium batteries are charged using constant voltage, while lead-acid batteries are charged using constant current. Lithium battery chargers use a constant current-constant voltage (CC-CV) charging mode, while lead-acid battery chargers mostly use a constant voltage or staged constant current charging method. Furthermore, the voltage levels of lithium batteries and lead-acid batteries are not compatible. Using a lead-acid battery charger to charge a lithium battery can cause bulging, deformation, and even explosion. Using a lithium battery charger to charge a lead-acid battery makes it difficult to fully charge the lead-acid battery. Over time, the lead-acid bat...

If a switching power supply is faulty, 90% of faults can be located by following the four steps of "Inspect - Test - Disconnect - Replace":   1. Inspect After powering off for 5 minutes, visually inspect the housing for bulging, burning, blown fuses, or capacitor leakage, taking photos for record.   2. Test Use a multimeter in the DC range to measure the main capacitor: 300 V ±10% at no load. Below 250 V indicates a defective rectifier bridge or filter. Measure the output: No load should be ±5% of the nominal value; short circuit should be 0 V, the fuse is intact, and the secondary rectifier is broken.   3. Disconnect Unplug the load and use a 30 W/12 V automotive light bulb as a dummy load: If the light bulb lights normally, the power supply is OK, and the problem lies with the load. If it does not light or flickers, proceed to the n...

  Cleaning equipment refers to mechanical devices used for cleaning floors, walls, ceilings, and other areas, such as sweepers, vacuum cleaners, floor scrubbers, high-pressure washers, etc. These devices typically require chargers to recharge their built-in batteries in order to ensure their normal operation. So, how can we maintain and care for the chargers of cleaning equipment? Here are some common methods:   1. Regularly inspect the appearance   Regularly check if the charger has any damage, cracks, deformations, etc. If any obvious damage to the casing is found, it should be immediately discontinued from use to prevent risks such as electric shock or fire.   2. Avoid excessive pulling   When using the charger, avoid excessive pulling of the power cord, especially the charging head. Excessive pulling may lead to wire breakage or poor internal connec...
