How to Fix A Portable Jump Starter?

Last Updated on

A portable jump starter is crucial for motorists, and understanding how to recharge it is critical to its maintenance. It can juice up your dead car battery whenever it dies on the road or even when you are at home. Has one of your portable jump starters stopped working recently? Are you wondering whether you can fix it? Here is a guide on how to fix a portable jump starter. So, let’s start with why a portable jump starter is not working.

Why is Portable Jump Starter Not Working?

A common issue is a faulty battery or damaged terminals. Knowing the best portable jump starter options can help you choose a reliable one. You can only know this when you open up the jump starter. There are, however, some apparent conditions that might cause the malfunctioning of a portable jump starter. A good example is if the cables appear worn out, there might be a disconnection. Replacing the jumper cables might be a quick fix for this problem.

The plastic surrounding the jump starter might also melt with extended use. And therefore it might stop working. All in all, to know the problem, you must open up the portable jump starter. You will need a regular set of tool kits, such as screws and knives, to repair a portable Jump-starter.

How to Fix a Portable Jump Starter?

1. Start by Opening Up The Portable Jump Starter

While it can be challenging due to its small size, understanding the internal structure of portable jump starters can aid in the repair process. However, you can look for where the screws are located and open them up. If there aren’t any screws present, then look for openings joining the parts of the portable jump starter. With the help of a knife, make shallow cuts and try opening them. Be gentle so you don’t expose the blade to the circuit board or jack. Doing this might make the problem more severe and complicated. A small flat-blade screwdriver can help you pry out parts easily without causing damage. Don’t force open any parts.

2. Analyze The Inside Parts

This is where it gets a bit technical. Each jump starter varies internally; familiarizing yourself with different types of jump starters can provide insight into their structure. However, there will be a circuit board, terminals, and battery cells. Look for anything that might look out of the ordinary, such as the accumulation of plastic wrappings on circuit boards, terminals, or the ends of the battery cells.

Take more interest in the batteries if they look over-drained. Replacing them can make your Jumpstarter begin working as they were. Before you close up the setup, you can permanently remove any plastic remnants from the circuit board with a knife or screwdriver. Look for wires that might have been eaten up or have become loose. Ensure they are also well connected from the batteries to the circuit board.

3. Battery replacement of Portable Jump Starter

It will depend on the make of your portable jump starter. In some jump starters, the batteries are located near the circuit board at the top opening of the portable jump starter. In others, they are placed at the bottom. When replacing the battery, it’s crucial to remember the connection sequence. For more information on battery maintenance, explore how to resuscitate a deeply discharged AGM battery. You can photograph the connection before dismantling it so that you can later reconnect it to how it was.

You might also find a compatible match with batteries. You can quickly get this from your nearest electronics shop. The connection of the battery terminals also has to be soldered. You, therefore, need to have a soldering gun with you.

4. Replacing The Connector Jack

If you find a melted connector jack, it might be time to check out different jump starter models for a potential replacement. This is due mainly to exposure to electric currents and high temperatures. If the connector jack for your portable jump starter has melted, it might have also exposed the wires beneath it. You, therefore, have to look for any signs of wire damage. Start by cutting it entirely and analyzing the thick gauge wires beneath it.

You will need another connector jack to replace the one that is damaged. You can salvage this from another portable jump starter or buy it from an electronic shop. Then, you can solder the exposed terminal wires and return the connector jack to its original place.

5. Insulating and Binding The Portable Jump Starter

Once you are sure that everything is working as it should be. Properly insulating and binding your jump starter is crucial for its longevity.

Don’t forget to secure the connector jack to avoid having it melt from the excess heat in the future. You can use a tie wrap to do this.

Now that everything is in place, you can add some finishing touches with silicone adhesive. If possible, coat the entire charge board and let it dry for the next day or so.

6. Recharge and test a Portable Jump Starter Pack

After repairs, recharge your jump starter fully. For more on this, see how to charge a jump starter pack. Take them out for a test drive in your car and see if it works. The portable jump starters should work if you carefully carry out the above steps. If not, the problem might have been with the circuit board, and you might have to take it to a technician for further repair. However, underlying issues with your portable jump starter, such as damaged wires, worn-out battery cells, and melted connector jacks, can be easily fixed at home. If your portable jump starter has undergone many repairs, it could be high time you get a new one.
