A car battery is a typical lead-acid type of energy storage device, consisting of the battery's positive terminal side from the side of a negative terminal of the battery 6 independent cells. Is the energy of each cell stored a voltage of about ADD71, which means that a fully charged battery with all normal operating cell will display a stored voltage of about 12 volts. Later, when a full overnight charge, the total voltage battery voltage reading 10.5 volts or less, which is a strong indicator that a cell has been damaged, or that itself and the other between its sides has a very short. To determine whether the battery is a poor contact or short-circuit of the battery, there is provided an appropriate charging and then test the battery charge cycle is complete.
1
Disconnect the car battery, the battery charger from the car and the car next to it. The charger cable to the negative battery negative terminal, and then connect positive positive terminal of the battery charger cable is connected to. , And then insert a fully charged overnight charger, and set it to allow charge to happen.
2
Close the battery charger, then disconnect the power Multimeter ADD81. Quickly remove the battery cable terminal.
3
Turn on your digital multimeter set to measure 20 volts DC. Touch the black test probe tip to the negative terminal of the battery, and then touch the red test probe tip to the positive terminal of the battery. Allow a few seconds, the voltage readings displayed on your instrument. If the voltage reads 12 volts or slightly more, your battery is healthy. However, if the voltage reading of 10.5 volts or lower,your bad battery cell or shorted together two cells.
Tip:
If your battery is not "maintenance-free" type, and the top of the removable cover, remove the cover and shine a flashlight into every cell, and then observe whether the cells are dry in the cell reservoir. If this is the case, the cell is filled to just below the pour hole of the lower edge, and in accordance with the above steps again. Improper maintenance of the fluid in the battery may damage a cell, causing it to short with another nearby cell or stop working altogether, because it is unable to perform the chemical storage process.
Car battery charging in a well-ventilated place, in the process of charging may cause the ADD71 Sensor Simulator to release hydrogen, which may cause a spark bombings.
