The discharge capacity of the need to use a special battery detector test.
We will generally use a voltmeter to check battery voltage, can detect the battery voltage value but can not check the battery with a load capacity of
the good or bad. To check out the actual situation of the battery, we should use the dedicated battery tester to check the battery discharge capacity and the
ability to load.
Weak current can not be ignored.
Lock your car, vehicle anti-theft system will be obtained from the battery weak current, so do not have the car for a long time can lead to battery power
shortage. Such as the vehicle is stationary for a short period of power shortage, in addition to check the battery condition, but also check the vehicle
stand for the weak current is too large. Vehicle stand for the weak current is likely to be caused because the interior part of the grounding of electrical
wiring and, if not addressed early will lead to security risks at the same time the battery is long over-discharge will it shorten the life span. Vehicle
maintenance industry generally use a clamp meter to detect the weak current when the vehicle standing.
The battery icing how to do?
Since the batteries inside the battery fluid is water and sulfuric acid, then the battery at low temperatures are likely to turn to ice. Case of battery
icing, as the owner, how should I do?
First we study the battery of the battery fluid will not freeze exactly, let's take a look at the battery icing, how should we do?
Battery icing, our cars will not start. We should remove the battery from the car to melt and then loaded into the car to use and then moved to the
indoor heated battery fluid. Of course, the night the batteries to bring the house warm place to save battery icing can be avoided.
Battery will freeze it?
Battery will freeze in the following cases:
1) Add distilled water too much cause battery fluid density decreases, water accounts for the increase in the percentage of battery fluid lead to the
freezing point of the battery fluid to rise.
2) excessive discharge of the electrolyte density decreased, the proportion of sulfuric acid and water imbalance in the battery fluid freezing point
The freezing point of the battery electrolyte is how many degrees Celsius?
Normal battery sulfuric acid concentration of 35% -40%, according to the freezing point of sulfuric acid - water mixture freezing point curve we can see
that the electrolyte between about -60 degrees Celsius to -50 degrees Celsius. From the data, as long as the battery fluid density between 1.25-1.30, the
unlikely occurrence of ice (unless your car in place of the very northern part of China).
However, with the decline of the concentration of sulfuric acid, battery fluid freezing point of the attendant rise, which makes battery fluid freezing
may be. For example, the winter minimum temperature is generally more than 10 degrees below zero, when the battery fluid densities as low as 1.10, the
battery will have the possibility of ice. Caused by the above changes the most common cause is over-discharged battery.
How to avoid the over-discharged battery:
1) while waiting, to avoid the use of high-power appliances. High-power electrical appliances, including headlamps, fog lamps, heated seats, stereo and
2) Parking to leave before check the headlights and interior roof light is turned off. In general, a normal fully charged battery make headlights for two
hours. With the reduction of the battery rated capacity, the headlights work properly the time is shorter. If left in the parking forgot to turn off the
headlights, the vehicle computer does not automatically put out the lights, the next morning, not the car up to 99% chance.
3) a long time without vehicle battery negative should be pulled down. Due to parking, vehicle electrical systems, there is a weak current consumption
and long standing vehicles will lead to the battery is depleted. Therefore, for long-term use of vehicles, we should be the negative battery pull down, to
avoid battery power too quickly spent.
Summary: In most regions of China, a state of good lead-acid batteries will not produce ice phenomenon. Owners friends should usually be a lot of
attention to the vehicle battery, check battery status on a regular basis, to avoid excessive battery discharge. Such as the battery has come to years, and
found the vehicle difficult to start, headlight brightness is insufficient, we recommend that owners have to replace batteries as soon as possible as well. visit http://www.leoch.com
