In the cold winter, how to maintain a car battery to avoid break down? Today to share some knowledge about battery conservation.

The general car battery is lead-acid batteries. Common lead-acid batteries There are 2 types, one is added to water lead-acid batteries, the other is maintenance-free lead-acid batteries.

Lead-acid batteries with water: common battery plate is made of lead and lead oxides, the electrolyte is an aqueous sulfuric acid solution. The advantage is voltage stability, the price is cheap; drawback is the low battery storage of electricity per kilogram, short life and frequent routine maintenance.

Maintenance-free lead-acid batteries: maintenance-free batteries due to the advantages of its structure, the electrolyte consumption is very small, basically do not need to add distilled water in a lifetime. It also has a shock, high temperature, small size, low self-discharge characteristics. Life is generally twice the normal battery.

Maintenance-free batteries on the market, there are two: the first after the time of purchase plus a one-time use, no maintenance electrolyte; the other is to have a good plus battery electrolyte and sealed the factory itself, the user simply can not plus liquid supplement.

Winter car battery how to care?

After using the car battery used in more than two years, the capacity and the discharge capacity will decrease, the general car battery life of no more than 4 years. Of course, well-maintained battery life will be longer.

Lead-acid batteries with water: focus on the battery fluid level and battery fluid density

As the owners, we should check the battery fluid level regularly. When the battery should be distilled water was added to the appropriate level. After adding distilled water to the battery, we should check the battery fluid density and keep the battery fluid density within a reasonable range.

Maintenance-free lead-acid batteries: Eye of regular inspections and maintain adequate power

Since the battery is not maintenance-free water was added and the battery fluid level scale holes, we need to determine the state of the battery through the "Eye" on the battery. Eye green indicates that the battery is normal, full charge; Eye black expressed the need for charge; as a white eye of the battery needs to be replaced.

Discharge capacity of the battery requires a special detector test

We typically use a voltmeter to check the battery voltage, while the voltage value of the battery can be detected but can not check the quality of the battery with a load capacity. To check the actual status of the battery, we should use a dedicated battery discharge capability of the battery tester inspection and with a load capacity.

The weak current can not be ignored

After locking the car, vehicle anti-theft system to work, it will get weak current from the battery, so the car can lead to a long time without battery power shortage. Such as found in the vehicle is stationary for a short time on the lack of electricity, in addition to check the battery case, also check whether the vehicle weak current when standing too large.

The vehicle was allowed to stand weak current is too large it is probably because the automotive caused Ground line portion, if not early treatment will lead to security risks, while discharging the battery over a long time will shorten its life. Automotive repair industry generally use the clamp meter to detect a weak current when the vehicle is standing.

Tip: battery is a consumable, if the performance and power had decreased, the proposed owners to replace as soon as possible, to avoid security risks.
