Method of selecting and using automobile battery.deep cycle trolling motor battery

　　1. Do not replace the battery with a larger capacity than the primary battery. Because the power output of automobile generator is fixed. If the battery with large capacity is replaced, the new battery will not be fully charged, the car will not start smoothly, and the battery life will be shortened if the battery loses power for a long time.

　　2. When starting the vehicle, the starting time shall not exceed 3 to 5 seconds each time, and the interval between restarting shall not be less than 15 seconds.

　　3. When buying a battery, read the letters on it. Those with QA letters are dry-loaded batteries.

　　4. Shake the electrolyte well before adding it to the battery. Please wear gloves during operation, and be careful not to spill electrolyte on your hands or clothes.

　　5. If the vehicle is not used for a long time, it should be started every 25 days and run for about 20 minutes at medium speed. Otherwise, it will be difficult to start the car if it is left for too long.

　　6. Do not let other items fall into the battery when adding electrolyte. If something falls into the water accidentally, never use metal materials to catch it. Use wooden sticks to clip out impurities; If iron wire or copper wire is used for fishing, metal molecules will enter the battery under the corrosion of sulfuric acid to form self-discharge and damage the battery.

　　7. Regularly check whether the small hole on the battery cover is ventilated. If the small hole is blocked, the gas generated will not be discharged, and the battery shell will be broken when the electrolyte expands, thus reducing the battery life.

　　8. Check the level of electrolyte regularly, and add electrolyte in time when the level drops.

　　9. For batteries without marking lines, the electrolyte should be 10 to 15 mm higher than the plate; For batteries with two red lines, the electrolyte shall not exceed the upper red line. Some people think that the more electrolyte, the greater the charge. This is a wrong idea. When the vehicle is running at high speed, the generator output voltage is greater than the battery voltage, and the battery begins to be charged. When charging, the volume of electrolyte expands. If the electrolyte is too full, it will overflow from the small hole of the battery cover. Once the electrolyte conducts electricity and flows between the positive and negative poles of the battery, it will form a circuit self-discharge. The car cannot be started and the battery life is shortened. In this case, wipe off the electrolyte with cotton wool or rinse it with boiling water.

　　10. When removing the battery from the vehicle, the negative pole should be removed first and then the positive pole. The installation is the opposite. When charging, the battery cover must be unscrewed. Do not use an open flame to approach the charging battery port, because the hydrogen generated in the battery is easy to deflagrate. After reading the above introduction, do you know the selection skills of car battery capacity. Most vehicle batteries are dry-loaded batteries. Its advantage is that it does not charge after adding electrolyte, and can be started after 30 to 40 minutes. Some car owners do not understand the working principle of the dry-loaded battery and will not maintain it, which greatly shortens the battery life.

　　Battery capacity knowledge

　　1. What is battery capacity?

　　Battery capacity is one of the important performance indicators to measure battery performance, which represents the amount of electricity discharged by the battery under certain conditions. You can take how much water can be stored in the pool as a reference. The battery capacity actually refers to the size of the battery storage capacity.
