I have a Toshiba laptop power adapter, the output is 15V, 3A, can you directly to the 12V car battery charging, charging current size is appropriate, hope to inform in detail.
Certainly is possible, that is, do not charge too long on the line,
You can start the car directly on the car with the charge. A long time will damage the battery
Can be nominal 12V battery new battery is filled with 14.8 volts, and if it is used for some time the battery is full of 14V. But the time to control, it is best to use a multimeter to measure, charge to 14V on it. My battery is often won down to charge, due to long-term low-speed, the car's generators simply dissatisfied with the battery long-term loss is easy to bad
Your adapter current is too small and may take a long time to see the size of your battery capacity. Because your voltage is also a bit high, after a period of time is best measured with a multimeter, overcharge will damage the battery.
Generally speaking, as long as the generator work properly, the battery is not required to charge! If the generator power generation is small, in short supply when the need for auxiliary charge! Auxiliary charge should pay attention to: First, the battery positive and negative and the charger to the correct connection, positive, negative to negative! Second, the charge voltage to correspond to the battery!
It is not to go to repair the next, not how much money, once and for all, to avoid a lot of trouble
I wish you success! The
Look at your battery is how much AH, the general constant current rechargeable battery capacity (AH) 1/10, such as the battery capacity of 60AH or so, should be about 6a (fast charge does not exceed 1/5, that is, 12A power) The voltage between 14-15V charge to the battery voltage at 14.4V or so continue to charge 3 hours
Constant voltage charging to 16V power supply current is less than 20A charge current to zero (that is, no current flow to the battery, put 3 hours without change) with a universal table can be, your power is very close to the charging data, charging absolutely no problem Suitable for constant current charging, may be slower, can not charge very full, but the current is small, the battery protection is good enough for you to use), spend more time to measure the amount of voltage with the current to buy about 100 of the charger are generally Very water is not as good as your power I use the 15V 5A laptop power is very good
