There are several ways to determine if a lead-acid battery is fully charged, including voltage monitoring, changes in charging current, and observing battery status. Different methods can be used depending on the situation, as detailed below:   Voltage is the most crucial method. Lead-acid batteries have rated voltages such as 12V and 24V. The open-circuit voltage after a full charge (after disconnecting the charger and letting it stand for 1-2 hours) has clear standards:   12V lead-acid battery: The open-circuit voltage after a full charge should be 12.7V~12.8V; if in float charging mode (charger not disconnected), the float charge voltage is usually 13.5V~13.8V.   24V lead-acid battery (composed of two 12V batteries in series): The open-circuit voltage after a full charge is 25.4V~25.6V, and the float charge voltage is 27V~27.6V.   If the batter...

  To prevent your smart charger from malfunctioning and bulging during the hot and humid summer months, remember the five key principles of cooling down, reducing the load, protecting it from sunlight, preventing moisture, and frequent inspections. Here's how:   Cooling Down - Find an air-conditioned room for your charger. For every 10°C increase in ambient temperature, the lifespan of electronic components is halved. Keep the charger in a well-ventilated, cool area away from direct sunlight and heat sources. If charging outdoors, use a parasol or reflector to keep the ambient temperature ≤40°C.   2. Reducing the Load - Avoid Charging While Charging In high temperatures, avoid operating your robot vacuum cleaner at high loads while charging (e.g., charging while sweeping). This will cause double heating. Let the device sit for 10 minutes to co...
