How to choose and buy car batteries

It is best to buy new products - Guangzhou Municipal Bureau of Industry and Commerce reminds consumers that when purchasing automotive batteries, they should confirm that the specifications, models, dimensions and terminal positions meet the requirements of vehicle installation and use; In addition, the starting capacity index of dry charged battery is time-sensitive.
Pay attention to the liquid level - the electrolyte level of the automobile battery should always be kept between max and min. Check it once a month, and add distilled water appropriately according to the drop of the liquid level. Do not add acid.
Prevent the battery from overcharging or long-term power loss - overcharging will cause the active material to fall off, and the power loss will cause the plate to vulcanize. It is necessary to ensure that the voltage of the regulator cannot be too high or too low. To prevent the battery from discharging with large current for a long time, the starting time of each use shall not be greater than 5 seconds, and the interval between two consecutive starts shall be 10-15 seconds.
Prevention of corrosion - The oxide and sulfate produced by the battery clip must be scraped and coated with Vaseline to prevent further corrosion, and the dust, dirt and spilled electrolyte on the battery cover should be removed frequently to keep clean and dry to prevent self-discharge.
Driving in cold areas - avoid complete discharge to avoid freezing of electrolyte.
