Problem One: Everstart Jump Starter Beeping 

One of the most common problems Everstart jump starter users face is that the device starts beeping and blinking. This could indicate a problem with the jump starter’s battery. 

Reason One: Loose Connection

If your Everstart jump starter is beeping and blinking, the first thing you should check is the connection of the jump starter with the battery.

The Everstart jump starter will make a two-second long beeping sound every 10 seconds if the jump starter is ON but not properly connected to the car’s battery. 

It needs to be connected properly to the battery, even if you’re trying to jump-start the likes of Range Rover.


Check the connection with the car’s battery terminal. When jump-starting a car, it is crucial to know whether the system is negative-grounded or positive-grounded. 

In the case of a negative grounded system, connect the red clamp to the negative post of the battery.

Make sure that the black clamp is attached to a portion of the frame or engine block that is made of metal and is away from the battery. Avoid connecting to sheet-metal body parts, fuel lines, or the carburetor.

In a positive-grounded system, do the opposite. The black clamp goes on the negative post of the battery, and the red clamp goes on a heavy gauge metal portion of the frame. Similarly, avoid connecting to sheet-metal body parts, fuel lines, or the carburetor.

Reason Two: Low Charge

If the connection is properly set, check if the jump starter has enough battery charge left. Check the battery status on the display screen. One bar will mean a low battery charge.


If your Everlast jump starter has a low battery charge, you need to recharge it. Here’s how-

  • Remove the protective cover from the built-in 120V AC charger.
  • Connect the charging cable to the charger and plug the other end into a standard 120-volt AC wall outlet.
  • Using the Battery Status icon on the LCD, you can see how much charge is left in the battery. While the unit is charging, the Battery Status Icon will constantly change from empty to solid and the backlight will turn on for only 10 seconds.
  • You should charge the unit for around 24 hours or until four solid bars appear on the Battery Status Icon. The extension cord should be disconnected from the unit once the charging has been completed.

Reason Three: Dead Battery 

If the mentioned reasons are not responsible for the issue, it has to be a dead battery.


To test if your Everstart jump starter battery is working, you need to perform a load test on its battery. You’ll need a load tester to perform a load test. 

Start by turning off the unit and removing its cover to access the battery compartment. Next, connect a load tester to the battery terminals and turn it on to apply a load to the battery. 

Keep the load on for 10-15 seconds and observe the voltage reading to see if the battery can hold the load. If the voltage drops below 9 volts during this time, it indicates that the battery is defective.

In case of a dead battery, a replacement is in order. Here are the steps to replace the battery of your Everstart jump starter-

  • Turn off the jump starter and unplug it from any power source.
  • Make sure all screws and clips securing the case or cover in place have been removed. This will typically involve removing screws located on the bottom or back of the unit.
  • Once you have removed the screws or clips, carefully separate the jump starter’s casing or cover from the unit. Be sure to note how the case or cover is attached, so you can put it back together correctly.
  • Locate the battery compartment inside the jump starter. This will be a small area inside the unit that houses the battery.
  • Carefully disconnect the battery cables from the old battery, making sure to note which cable is connected to which terminal (positive or negative).
  • Remove the old battery from the compartment.
  • Insert the new battery into the compartment, making sure it is oriented correctly and securely in place.
  • Make sure the battery cables are connected to the correct terminals on the new battery.
  • Replace the casing or cover of the jump starter, ensuring that it is reattached properly and all screws or clips are securely in place.

Now, you can turn on the jump starter and test it to make sure it is working properly.

Make sure to responsibly dispose of the old battery.

Problem Two: Everstart Jump Starter Won’t Charge 

Another common problem the Everstart jump starter users struggle with is that the device is not charging itself. There are a couple of reasons for this problem.

Reason One: Temperature Not Suitable

This may or may not be news to you, but your jump starter will not work properly without a favorable temperature. 

For lead-acid batteries, the ideal operating temperature would be 50 to 70 degrees Fahrenheit. For, lithium-ion batteries, the temperature is 41-68 degrees Fahrenheit.


Take the jumpstarter to a suitable temperature and try again. 

Reason Two: Faulty Cable or Charger

If your jump starter is not charging it could be due to a fault in the charging cables or the charger. 


Try using a new cable for charging your jump starter. Only use the manufacturer-recommended charger and extension cord for charging your jump starter.

Reason Three: Dead Battery

If there is no problem with the charger or the cable, it could be a dead battery.


Check out how to deal with a dead battery from the previous section.

Problem Three: Everstart Jump Starter Making High-Pitched Noise 

Sometimes your Everstart jump starter may make a continuous high-pitched noise. This is due to a reverse polarity alarm. 

Reason: Reverse Polarity Alarm

The reverse polarity alarm sounds when you have connected the clams to the wrong battery terminals. That means, the negative clamp is connected to the positive terminal and vice versa.

As the reverse polarity alarm is triggered, the “Battery Status” icon, the “Battery Voltage Indicator”, the “Clamp Icons”, the “Alarm Icons”, the “+” and “-“ signs, and the “Reverse Polarity Icons” will flash.

Disconnect the clamps from the car’s battery terminal and reattach them in correct places.

Problem Four: Everstart Jump Starter Display Not Working 

Some users have faced an issue with the display not working. This may happen because of a low or dead battery.

Reason: Low Battery Charge or Dead Battery

Try recharging your Everstart jump starter; use the specific manufacturer’s charger and cable. While charging, turn off all of its functions. You need approximately 24 hours to completely recharge a jump starter. After recharging, see if the display works again.

If recharging does not work, this problem may be caused by a dead battery. 

How to Maintain Your Everstart Battery Charger

Maintaining your Everstart jump starter is important to ensure it operates effectively and lasts as long as possible. Here are some guidelines to help you maintain your jump starter effectively:

  • Charge the battery regularly: Batteries lose energy from self-discharge over time, which happens even more quickly at higher temperatures. So, it’s recommended to charge the jump starter’s battery at least once every 30 days when it’s not in use.
  • Keep the jump starter clean: Regularly clean the exterior of the appliance with a soft cloth. Don’t submerge it in water, as this can damage its internal components.
  • Inspect adapters, connectors, and wires: Check the condition of the adapters, connectors, and wires periodically. If any wear or damage is observed, it’s crucial to contact the manufacturer to replace the damaged components. Using damaged components can cause further harm or damage to the jump starter.
  • Store the jump starter properly: Store the jump starter in a cool, dry place, away from direct sunlight, heat sources, or moisture. Avoid storing it in a location where it could get knocked over or damaged.
  • Follow the manual: Always follow the manufacturer’s specific instructions for using the jump starter, including how to charge and operate it correctly. For example, if you can jump-start in the rain

By adhering to these instructions, you can ensure that your Everstart jump starter remains in excellent condition and performs correctly when you need it.

Frequently Asked Questions (FAQs):

Can you overcharge a jump starter?
