Can a car battery charger be used for direct power supply?
Can a car battery charger provides the same or higher amount of current as the car battery does?if yes, then can we use it as a direct source to supply current in home instead of using a battery?i have tried a 5amps. car battery eliminator but current is far less. please sujjest
Answer
The answer is no on both counts.
battery chargers are unregulated. when nothing is connected, the voltage can go as high as 16 volts. also, the output is unfiltered. it is
an ac chopped in two, not a smooth dc that one normally associate with dc. in some models, if you lightly load the charger, it will shutoff as it thinks charging is almost done.
no, it cannot
provide as much amperage as the battery. most of them charge at 10% rate, meaning if the battery was 60ah (which is capable of dispensing as much as 750 amps in short bursts) are charged at 6amp for 10 hours.
