An portable jump starter is one of the must-have tools for cars. When the car battery is low due to low temperature, long-term parking or over-discharge, the car cannot start. You can prepare a high-power portable jump starter supply for emergencies. The portable jump starter can independently provide instantaneous high current for low-power vehicles through built-in large-capacity lithium batteries or capacitors to solve the problem of starting the car. Especially for older cars, it is safer to prepare jump Starter. So how do you use it to start the car battery? The following are the steps to start the car battery:
Check equipment and vehicle status
Confirm that the portable jump starter has sufficient power (recommended power ≥ 50%).
Check whether the vehicle battery is low on power (the voltage can be measured through the battery icon on the dashboard or a multimeter, the normal value is 12.4-12.6V).
Make sure the vehicle is in neutral/park, apply the parking brake, and turn off all electrical devices (such as air conditioning, lights).
Environmental safety confirmation
Avoid operating in humid, high temperature (>60℃) or low temperature (<-20℃) environments.
Keep away from high temperature parts such as engines and pulleys to prevent dangers caused by short circuits or sparks.
Connect the positive terminal
Securely clip the red clip (+) of the portable jump starter to the positive terminal of the vehicle battery (marked with "+" or red logo), ensuring that the contact is not rusted or loose.
Connect the negative terminal
The black clip (-) should be clamped on the negative pole of the vehicle battery (marked with "-" or black logo), and do not connect the positive and negative poles in reverse to short-circuit.
Check the connection
Make sure the clip is not loose, not touching other metal parts, and the portable jump starter indicator light is normal (such as a solid green light to indicate readiness).
Start operation
Start the portable jump starter and start the car within 30 seconds. If it fails for the first time, wait for 1 minute and repeat the operation, up to 3 attempts.
After success, disconnect the power
After the vehicle is started, disconnect the black negative clamp first, then the red positive clamp to avoid sparks caused by the clamps touching metal.
Charging and maintenance: Keep the vehicle idling for more than 10 minutes after starting to recharge the battery; the portable jump starter must be charged within 24 hours to avoid long-term power loss.
Abnormal situation handling: If the vehicle still cannot start, it may be due to severe battery aging or circuit failure. You need to replace the battery or contact professional repair.
Prohibited operation scenarios: Do not use when the battery is leaking, severely bulging, or the vehicle is in water and has not dried.
Avoid misoperation: Reverse polarity will damage the device, and continuous startup for more than 3 times may trigger the protection mechanism.
Device storage: Charge once a month when not in use for a long time and avoid high temperature or squeezing.
The emergency jump starter is an efficient tool to solve the problem of vehicle power shortage, but its essence is "temporary emergency" rather than a long-term solution. It is recommended that car owners conduct a battery health test once a year and equip their vehicles with an portable jump starter that meets the needs of the vehicle model. I recommend our YD product, Portable Jump Car Starter, which has a variety of energy options, such as 14.8Wh, 22.2Wh, etc., and provides a USB interface, which can be used as a power bank. If the battery has been used for more than 5 years, or there are frequent startup difficulties, timely replacement can avoid the risk of breakdown.
