Tips On How To Make Your Jump Starter Last Longer

So, how can you ensure that your jump starter will work when you need it? Before we go into the repairs, you can do a few things to keep your jump starter in good working condition, extending its duration.

  1. Keep the battery charged, but don’t fully charge it because deep charging damages batteries and diminishes their total capacity.
  2. Because starting an automobile demands a lot of energy, you’ll be consuming a lot of your portable jump starters stored energy, so recharge it after each use to minimize over discharges.
  3. Keeping it safe from moisture as it can cause corrosion in the jump starter, reducing its ability to deliver energy.
  4. Keep it safe from extremes of heat and cold, as heat increases the self-discharge process, leading to sulfation and other battery damage. However, extreme cold inhibits a battery’s ability to produce energy.
  5. Keep the jump starter in a secure location, and do not let it roll around in your vehicle. It’s best to fasten it and wrap all of the wires to avoid difficulties.

Fix Your Portable Jump Starter Quickly And Effortlessly

It’s essential to keep a portable jump starter with you all the time, even in an emergency too. But what if the jump starter itself fails? But don’t worry since we will guide you on how you can quickly fix your jump starter in minutes.


  • Set of essential tools (screwdriver, wrench, etc.)
  • Portable Knife
  • Electronics Cleaner
  • Soldering iron (if replacing battery cells)

Steps To Follow

1. Test The Charger

If the device would not switch on, charge it for a full 24 hours. Recheck the charging cable or adapter if it still won’t switch on. To make sure this isn’t the issue, try using another adaptor or charging cord.

2. Inspect The Overall Device

Examine the external housing carefully under a bright light. If you notice any cracked, melted, deformed, or shattered pieces, the unit has most certainly received too much damage to be repaired. Continue to the next step if everything appears to be in good working order.

3. Remove The Outer Part 

Remove the external housing pieces with screws; if that isn’t possible, make several shallow incisions with a knife.

4. Inspect The Internal Wiring

Examine all of the unit’s internal wiring. Check for any loose or rusted connections. Any wires that look broken or rusted should be replaced, and all connections should be tightened.

5. Check The Connector Jack

The connector jack can become rusted, burnt, or melted in some cases. Replace it if it is significantly damaged.

6. Replace the Battery Cells

Examine the battery cells, as they may be worn out. However, lithium battery cells are widely available. Replace them in the device and get them in place with a soldering iron.

How Do I Reset A Jump Starter?

So firstly, without pressing the brake pedal, insert your ignition key and press the start button once. Then using your remote car starter, press the lock button. Return your key to the “off” position within five seconds of turning it on or press the start button again. Repeat this on-off cycle three more times, for a total of four.

Furthermore, when you pick the accessory position on cycle number four, you’ll hear a noise (a “ding” or “buzz”), which means that you’ve switched to programming mode. Then turn the car off by pressing and holding the lock button on the remote for ten seconds. Then double-check it, and you’re done.

Can We Charge A Jump Starter Without A Charger?

Yes. Many automobile battery jump starts may be charged by connecting them to your vehicle’s A/C adapter. The jump starter can pull enough power from your A/C outlet to keep a full charge and will be available when you need it. Alternatively, solar energy can also be used to charge it.

Are Portable Jump Starters Effective?

Yes. Portable jump starters are an excellent addition to any vehicle emergency kit since they provide a self-sufficient means of immediately starting a vehicle with a dead or dying battery. They start by delivering electricity from a portable battery to a drained vehicle battery.

These gadgets function by plugging special booster cables into a 12-volt power connector on one end and fastening them to a car battery on the other end, just like standard booster cables. In short, they are an excellent investment for automotive battery issues.


To summarize, portable jump starters are an absolute necessity for every driver nowadays because not everyone is always willing to assist you in getting to your destination. As a result, having a portable starter will raise your battery on its own, allowing you to be completely independent.
