We have summarized the four steps of common battery installation to help you safely remove old batteries and install new/replacement batteries.
Step 1 Choose the right battery
Please refer to your car manual for recommendations from car manufacturers:
Battery size — Refers to the battery that best fits the physical size of your car.
Cold start current (CCA) — CCA is the key to good starting performance. It is the current that a battery can generate when the battery voltage drops to an unusable level within 30 seconds under the condition of 0°F (-17.8°C).
20-hour rate rated capacity (C20)-it is generated by a battery at an ambient temperature of 80° Fahrenheit (26.7° Celsius), discharged at a current of one twentieth of the battery’s rated capacity at a 20-hour rate until the final voltage is 10.5V It calibrates the number of ampere hours that the battery has enough power to run the car before it drops to the termination voltage.
In general, the higher the values of CCA and C20, the better. However, if you live in a cold climate area, CCA performance is an important factor that you need to consider when choosing a battery. Conversely, if you live in a tropical high-pressure area, you do not need to consider excessively high CCA values.
Step 2 Take out the old battery
Check the owner’s manual for special instructions. Before removing the old battery, please pay attention to the position of the positive terminal of the battery and mark the polarity on the positive wire. Doing so can avoid installing a new battery.
Remove the “grounding” wire connector first. This precaution can prevent accidental tool “grounding” from damaging the wiring or the battery.
When removing the battery wires, use a socket wrench of appropriate size or an open-end wrench.
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 “grounding” wire, and tighten the connection between the starter relay and the starter.
Step 3 Install new battery
When installing the battery to the car, it should be placed horizontally on the pallet. Make sure that there are no foreign objects on the tray that may damage the bottom of the battery.
Fasten and fix 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.
Determine the correct battery polarity that meets the vehicle specifications.
Step 4 Dispose of the old battery
Contact an auto repair shop or repair station, most of them will accept old batteries for recycling, even if you did not buy their batteries.
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.
The above are the four steps we commonly use to install a car battery. Have you learned it?
