How to replace the car battery?

Step 1: Choose the right battery. The car will come with a car manual when it leaves the factory. You can learn about the car manufacturer’s advice in advance: the battery size is the battery that fits the physical size of your car. Cold start current (CCA) CCA is the key to good start performance. It is the current that a battery can appear when the battery voltage drops to an unusable level within 30 seconds under the condition of 0 Fahrenheit (-17.8 Celsius). 20-hour rate rated capacity (C20) It is the amount of electricity that a battery will discharge at a current of one-twentieth of the battery’s rated capacity at a 20-hour rate to a final voltage of 10.5V at an ambient temperature of 80 Fahrenheit (26.7 Celsius). It can determine the number of ampere-hours required for sufficient power to run the car without falling to the voltage. Under normal circumstances, the higher the values u200bu200bof CCA and C20, the better. However, if you live in a cold climate area, CCA performance is an important factor to consider when you choose a battery. On the contrary, if you live in a tropical high pressure area, you should not consider excessively high CCA values. Step 2 Take out the old battery Before taking out the old battery, please pay attention to the position of the positive terminal of the battery and mark the polarity on the positive wire. This can prevent the installation of new batteries. Remove the grounding wire connector first. This precaution can prevent accidental tool grounding and damage to the wiring, and/or the battery. When removing the battery wires, use a socket wrench or open-end wrench of the appropriate size. Check whether the battery tray is damaged or corroded. Ensure that the mechanical properties of the tray and the fixed splint are good and there is no corrosion. Corroded parts can be cleaned with clean water (some household ammonia or baking soda can be added), and scrubbed with a stiff brush. The cleaned parts should be dried and brushed with anti-oxidant grease. Clean and tighten the ground wire, and tighten the connection between the starting relay and the starter. The author of Baibai Safety Net recommends: Everyone must wear rubber gloves when replacing the car battery, which can prevent hands and clothes from getting dirty, and can also be used for non-slip purposes. Safety will be guaranteed to a certain extent. Step 3 Install the new battery. When installing the battery to the car, place it horizontally on the pallet. Make sure that there are no foreign objects on the tray that may damage the bottom of the battery. Fasten the fixation until the best condition, but should not bend or crack the battery cover or battery slot. Refer to the torque value determined in the owner's manual. If not available, please use the torque value shown below: Top plate or top frame pressure plate: 30-50 inch pounds Bottom groove type pressure plate: 60-80 inch pounds Bottom dark plate: 70-90 inch pounds The ground wire should be connected to the battery last . Determine the correct battery polarity that meets the vehicle specifications. Generally, the grounding polarity is displayed. Reverse polarity may seriously damage the vehicle's electrical system. Note that the positive terminal column is larger than the negative terminal. Step 4 Dispose of the old battery. Contact an auto repair shop or repair station. Most of them will accept the old battery for recycling, even if you did not buy their battery. Contact retailers that sell lead-acid batteries. Most retail outlets that sell lead-acid batteries also have waste battery recycling services. If you cannot find a retailer or installer to recycle the battery, please contact the recycling center or health department near your place of residence, they should be able to find a facility or place to safely dispose of hazardous waste; or contact your local garbage recycling company, they may There are collection standards and dates for specific hazardous wastes. , Statement: Some pictures and content of articles published on this site are from the Internet.
