The core reason why lead-acid and lithium batteries are "incompatible" is not that they can both discharge, but rather that their three major systems—voltage, chemistry, and protection—are completely different. Mixing them equals instantaneous damage and safety risks. I. Different Voltage Systems ItemLead-acid (12V example) Lithium-ion (12V example) Single Cell Full Voltage 14.4 V 16.8 V Open Voltage 12.8 V 12.6 V Cutoff Voltage 10.5 V 8.4 VResults of Mixing: Using lead-acid at 14.4V to charge lithium battery → will never fully charge, capacity decreases by 30%;Using lithium-ion at 16.8V to charge lead-acid → overcharge, water loss, bulging, lifespan halved. II. Different Chemical Systems Lead-acid: Three stages (constant current-constant voltage-trickle flow), trickle flow 2-4 hours, desulfurization; Lithium-ion: Two stages (...

A floor scrubber charger "not charging" usually indicates a combination of six faults. Follow the three steps of "look → test → replace" to quickly pinpoint the problem: I. Overview of the Six Faults | Fault | Symptom | Quick Diagnosis | | 1. No mains power | Indicator light off | Change socket → Light on → OK | 2. Blown fuse | Indicator light off, multimeter no 300V | Multimeter input → No power → Replace fuse | 3. Broken output wire | Light on but no output | Multimeter output → 0V → Replace wire | 4. Reverse battery connection/short circuit | Light flashing or 0V | Replace with same model battery → Normal → Battery faulty | 5. Bulging capacitor | Light on but low output | Multimeter ESR > 0.1Ω → Replace capacitor | 6. MOSFET short circuit | Light on but short circuit | Mult...

  Waterproof smart chargers cannot directly provide "explosion-proof" protection; they represent different levels of safety concepts, but can be used complementaryly in certain industrial scenarios. The conclusions are as follows:   ① Waterproof ≠ Explosion-proof - Waterproof (IP rating) (e.g., IP67) only indicates dustproof and short-term immersion capability, it does not prevent internal electrical sparks, high temperatures, or component failures from igniting surrounding explosive gases; - Explosion-proof (Ex rating) requires that even if a short circuit, spark, or high temperature occurs inside the equipment, it will not ignite surrounding flammable gases or dust, requiring explosion-proof, increased safety, or intrinsically safe structures.   ② Complementary in Industrial Scenarios In explosion-proof areas (e.g., gas stations, chemical workshops), ...
