Using Ohm's Law, we can calculate the time it takes to fully charge the battery:
Charging time (in hours) = (Battery Capacity in Ah) / (Charging Current in amps)
Charging time = 50 Ah / 1.5 A
Charging time ≈ 33.3 hours
Therefore, it would take approximately 33.3 hours to fully charge a 50 Ah car battery using a 1.5 amp trickle charger. However, it's important to note that this is just an approximate calculation and the actual charging time may vary depending on factors such as the battery's age, condition, temperature, and charging efficiency of the trickle charger.
