DC power supply can directly charge the rechargeable battery?
Voltage Match No, Jack Match No! If the match can be
From the principle is possible, as long as your regulator DC power supply is a constant voltage source, and the output voltage is stable, there will be no voltage instability, such as voltage rise (voltage drop ignored), with a DC power supply to the regulator Mobile phone charging is no problem, because I have been so operating! Rest assured, as long as your stable power output is stable enough, then charge it! Mobile phone charger is generally 5V, you transferred to the 5V! As for the security measures Well, the charge is away from flammable and explosive materials on it! (Voltage regulator if there is over-voltage protection that is the best, the power over-voltage protection value set to 5.5v).
For lead-acid batteries, according to the single cell 2.3-2.5V voltage set the charging voltage, that is, 12V battery for the six single cell, the charging voltage is set to 13.8-15.0V, with constant pressure way to charge.
1. First of all you have to look at the voltage is within the rated range, the capacity is not enough capacity and voltage to be slightly higher
2. Do not reverse the polarity of the power supply
3. Because you are not a dedicated charger, avoid charging too long!
Just pay attention to the above points should be no problem
Yes, but the effect is not good! Only one or two times, you can, a long time, the number of times, seriously affecting the battery performance. When used to adjust the adjustable voltage regulator output voltage. Can not be too high, otherwise there may be accidents, such as battery explosion, power damage and so on.
