Connect a Multimeter: Set your multimeter to measure current (amps) and connect it in series with the battery charger and the battery. This isn't just about knowing if the battery is receiving power; it's about determining if it's receiving the correct amount of power, which is essential for avoiding overcharging or undercharging, both. . Always monitor your battery charger amp meter to prevent overcharging, overheating, and deep discharging, which protects battery life and safety. Use the correct type of amp meter and follow safety steps before charging, including inspecting batteries and using proper protective gear. Regularly. . This circuit shows smart way to check charging current without multimeter. We used 2 watt resistor to feel the heat.
