Duralast jump starter 700 won’t charge

There are situations where you may find that your car’s battery is dead and the vehicle cannot move. It is so heartbreaking, especially when you are late for work or any other meeting that you were supposed to attend. In such a situation, you need your duralast jump starter 700 to enable you to start the car.  

But then something dreadful happened: when you needed your battery jump starter the most, it was unavailable. It’s dead and doesn’t charge. Therefore, it’s time to check and know what exactly is wrong with your duralast jump starter?

You will often find that your duralast jump starter battery is not charging because it’s dead. A jump starter’s battery packs must be adequately maintained, or they will not last long. Even so, they only have a few years’ worth of life before they need to be replaced. In this article, we will discuss why your duralast jump starter 700 won’t charge.

What type of battery does my duralast jump starter have, and how do I care for it?

Duralast jump starter 700 won't charge

Even if you are not using your cell phone, the battery will ultimately die. The battery in your jump starter goes through the same thing.

Lead-acid and lithium-ion batteries are the two main types of batteries used in jump starters. Lead-acid batteries are heavier and are used to power larger equipment such as an air compressor. On the other hand, your lithium-ion batteries are lighter, more portable, and may very certainly be utilized as a charging station.

These batteries are maintained in either situation. So, how do you keep a jump-starting battery charged? Simply by recharging it regularly. If you regularly use your battery jump starter, Clore Automotive suggests replacing it every two to three months. Clore also indicates that you charge your jump starter after every use. That ensures that you will have a full charge the next time you use it.

Shelf Life of Jump Starters: How Long Do They Last?

Another reason your battery jump starter isn’t charging is that it’s no longer capable of doing so.

A premium automotive battery has a lifespan of only five to six years. Alkaline batteries have a single life cycle, which varies depending on how they are used. Given reasonable care, rechargeable batteries can last two to seven years.

The idea is that all batteries will eventually die.

The battery is the essential part of your jump starter. When the timer runs out, it will no longer charge.

Yes, you could attempt replacing the battery in your jump starter, but doing so is usually prohibitively expensive.

Other Reasons Your Jump Starter Isn’t Charging


We’ve talked about how cold weather affects cars in general and battery jump starts in particular. Cold weather harms the battery in your jump starter.

In an ideal world, you’d be able to keep your jump starter box in your car and use it in an emergency. If you live in a complex winter climate, though, you may want to consider taking your jump starter box inside every night.

On the other hand, if you reside in a region where the temperatures reach dangerously high levels, your battery may be damaged. In the summer, the temperature inside my automobile in Florida can approach 120 degrees.

My jump-starting box’s battery will not perform at full efficiency after being exposed to those temperatures for a lengthy period. The recommended storage temperature for lead-acid jump starter boxes is 50°F – 70°F (10°C – 21°C). Jump starter boxes using lithium-ion batteries are more forgiving. The Noco Genius Boost GB40 may be stored at temperatures ranging from -4°F to 122°F.

Now, I would not experiment with the long-term effects of these severe temperatures. If you reside in a location where these weather extremes are common, you should bring your jump starter with you. The Moock MK1500 is a well-reviewed unit that weighs only 1.38 pounds, making it simple to transfer in and out of the automobile.

How to jump-start your automobile with a jump-starting box.

What type of battery does my duralast jump starter have, and how do I care for it

Remove the clamps from the battery as soon as possible after the car has been jumped. Of course, be sure that you disconnect in the proper order. What’s occurring is that a charge is being returned to the jump starter battery, providing it with more power than it was designed to handle at one time. As a result, the battery is damaged.

Second, the procedure of jump-starting an automobile might cause damage to the jump starter’s battery. When a battery unit tries to turn an engine over, heat builds up in the team, known as cranking. Clore automotive suggests a six-second ‘cranking’ period followed by a three-minute rest period. That will prevent heat from accumulating in the unit and save battery wear.

Charging Cable for duralast Jump Starters

When you’re trying to figure out why your jump starter won’t charge, think about everything. The AC adaptor or USB cord may be defective. It’s the same with our other mobile devices. Examine the cord for any signs of wear and tear. Make sure the charge indicator light on your battery jump starter is turned on. That is a dead giveaway that your charging cord isn’t operating correctly.

How to make your duralast Jump Starter Last Longer

So, how can you ensure that your duralast jump starter will work when you need it? Before we go into the repairs, there are a few things you can do to keep your jump starter in good shape:

  • Keep it charged at all times. That isn’t merely to ensure that the jump starter is ready to use when you need it. Batteries are harmed by deep discharges, which reduce their overall capacity. The easiest method to avoid this and extend the life of the jump starter is to keep it as close to full as possible.
  • After each use, charge it quickly. Starting an automobile requires a lot of energy, which means you’ll be using a lot of your jump starter’s stored energy. To avoid over-discharges, recharge the portable jump starter after each usage, even if it hasn’t been three months.
  • Heat, cold, and dampness should all be avoided. Anything that harms a battery will also hurt a jump starter’s performance. Moisture can cause corrosion in the jump starter, reducing its ability to deliver energy. As previously stated, heat accelerates the self-discharge process, leading to sulfation and other battery damage. On the other hand, extreme cold inhibits a battery’s ability to produce energy; therefore, it’s equally crucial to keep it warm.
  • Securely store the jump starter. It’s more likely to be harmed if the jump starter bangs around in your trunk than if it’s securely fastened. The best approach to avoid difficulties is to tie it down and keep all the cables bundled up.


When you purchase the Duralast Jump Starter 750 Amp, it does not include the AC charging converter. To charge it at home, you’ll need a second suitable AC adapter that’s CE, FCC, and RoHS certified. Short Circuit output Protection is built into this dependable jump starter for added safety. Here are the measures you must take.

o   Check that all of the Duralast jump starter switches are off.

o   Connect the AC adapter to the charging port on your Duralast.

o   Connect the adapter’s other end to a power outlet in your home.

o   If the Duralast battery has started charging successfully, an LED display will illuminate. Turn off the power and double-check the cable connections if you haven’t already.

o   Turn off the power source and unplug the AC charging adaptor once the battery has finished charging.

o   Disconnect the AC charging adapter connector from your Duralast jump starter next.

o   Keep the adaptor somewhere secure.

o   Before using your jump starter, wait a few minutes (5).

Frequently asked questions;

Is it necessary to let a car run after jumping it?

You can’t just drive away as if nothing happened, whether you’re using the right size jumper cables or a battery jump-starter. Allow some time for your car’s battery to recharge.

After giving your automobile a jump, you should let it run for at least 5 to 10 minutes. Maybe even revving the engine a little more (2000-2500 RPMs).

That was a rule of thumb for a Triple-A tow truck driver. He’d jump-start a car and leave it running for five minutes.

He’d then turn the car off and wait ten seconds before restarting it. Then he’d continue the automobile, and if it started, all was well. He understood there was an issue with the battery if the car wouldn’t start and would advise the customer to a repair shop.


So what’s the deal with my duralast jump starter not charging? As we can see, all batteries, including the one in your jump box, have a shelf life. First, consider the age of your unit; is it time to replace it? Second, to get the most out of your battery jump starter, you must maintain it well.

Every two to three months, make sure the jump starter is appropriately charged. If you need to use it, ensure it is fully charged before doing so. Keep in mind where the jump starter is stored. Extremely hot or cold temperatures will reduce the unit’s lifespan. Finally, double-check that the jump starter is in good working order.
