Question:

Adjustable DC regulated power supply can charge the car battery?

Voltage range: 0-30V, current range: 0-5A, the power output can charge the car battery?

Answer:

Should be able to, just charge a little longer. Because the charge current can not exceed 5 amps. So the capacity of the battery time will be slightly longer. Finally, determine whether the battery charge is full. Depending on whether the battery electrolyte concentration reached 1.28
There are many kinds of car level, usually as long as the maximum current charger does not exceed the battery charge current; the maximum voltage of the charger, not more than the battery voltage, can be charged. But it is best not to use this, because the charger is usually constant voltage, constant current charge. In other words, the battery is not enough constant current charge, the battery is saturated when the constant voltage charging. But if you can not find the right charger, the above adjustable power supply can be used as a charger, but pay attention to the charging current, otherwise the battery easily affect life.
Yes, according to your car battery capacity to adjust the charging current can be, generally use the battery capacity of one-tenth of the current charge (such as 45a battery is charged with 4.5A current 10 hours or so, the longer the current the longer the longer) The I do not know your power supply has no constant current function, if there is a direct transfer of current, the maximum voltage can be set to 14.8v. If not only on the voltage as the standard, connect the charging line will be reduced power supply knob, turn on the voltage slowly to ensure that the current does not exceed the battery capacity of one-tenth and 5A, after a while the current will slowly decline , Then turn the voltage a little higher, and finally when the voltage to 14.8v (can not exceed), the current becomes very small when the battery is full.
