When purchasing a jump starter, you will find that the trip starter manufacturer has little consistency in marking the trip starter. Some manufacturers only list peak amperage, some starting amperage, cold start amperage or just "amperage", some mAh and (usually) combinations of them in their product specifications. Some even list Joules to make you more confused. what is the difference? Buy a starter for your atv, car, truck or snowmobile, which one is a better reference and guidance?
Below is a list of definitions to help you understand the meaning of the jump starter terminology.
Peak current definition – Typically, the peak power rating is impressive, and if you have information, it is recommended to always refer to the start current and cold start current when comparing Jumpstarter. If you don't do this (which is usually the case), you can use the peak amperage as a comparator because most manufacturers have recently listed peak amperage details. Then, compare the 400 peak amperage jump starter with the 1000 peak amperage jump starter, which is theoretically "stronger".
Start Current (CA) Definition – Refers to the battery's ability to discharge for 30 seconds at 32°F (0°C). In fact, this is the power required to start the engine in any weather other than winter.
Cold Start Current (CCA) definition – refers to the amperage that the battery can be launched for 30 seconds at 0°F without falling below 7.2V. Keep in mind that the starter is basically just another battery that powers the car's battery. Starting up the engine in cold weather is more difficult because of the thickening of the oil and the increased resistance to motion inside the engine – which is why the battery often has both CA and CCA ratings.
mAh – milliamp hours (mAh) is one thousandth of an ampere-hour (Ah). Both methods are used to describe the amount of energy the battery will hold and how long it will take before the device needs to be recharged.
Joule – you can find a very detailed explanation on Wikipedia, but for beginners, even if it’s
Generally, a higher starter amplifier rating is better because this will be the actual power to start the battery. A starter with at least a 500 CCA rating should be able to start almost all vehicles with exhausted batteries. When it comes to peak amperage, most peak engines should start with 1000 peak amp battery boosters.
When it comes to peak power ratings, if you have multiple cars, all of them require only one jump starter. Just make sure it can start the biggest vehicle. There is no need to worry about circuit overload in small vehicles, because the jump starter will only pull enough power to start your car. When using a jumper-type starter, power will flow into both the depleted battery and the starter motor, which is why it is difficult to start the car with a completely dead battery. The exhausted battery will absorb more. Electricity.
If you suspect that the battery is exhausted or is about to run out, be sure to get the highest cold start current rating. In the unlikely event that your battery is dead, this type of jumper is most likely to recover the used battery.
