Type S Jump Starter Says, “Battery Protected, Unplug, Start Over” [Solved]

Type S jump starters are famous for the top-notch features they include in them. One of which is the “Battery Protected” feature. But what does it mean when a Type S jump starter says, “Battery Protected, Unplug, Start Over?”

The message means that you have connected the jumper cables to the wrong battery terminals. When this happens, turn the jump starter off immediately and disconnect the jumper cables. Then reconnect the jumper cables in the correct order. This error can damage both batteries. In the worst-case scenario, the battery may explode.

What Does “Battery Protected” Mean? Type S Jump Starter Says, “Battery Protected, Unplug, Start Over”

When a jump starter is “battery protected,” it means that the device has built-in safeguards to prevent damage to the battery during the jump-starting process. Only some of the top-rated jump starters include this special feature.

Jump starters work by providing a boost of power to a dead or weak battery, allowing it to start the engine of a vehicle. However, if the jump starter delivers too much power or doesn’t regulate the power correctly, it can cause damage to the battery.

A battery-protected jump starter protects the battery from overcharge protection, over-discharge protection, and short-circuit protection. These features help prevent the battery from being overcharged or discharged. These can damage the battery cells and reduce their lifespan. 

Overcharging damages your jump starter battery more than discharging.

Short-circuit protection, on the other hand, prevents the jump starter from delivering too much power to the battery all at once, which can also damage the battery.

Type S Jump Starter Says “Battery Protected, Unplug, Start Over”: Solution

If your Type S jump starter is displaying the message “Battery Protected Unplug Start Over,” it is likely due to a reverse connection of the jumper cables. This means that the cables have been connected in the wrong order, with the positive and negative terminals reversed.

To solve this issue, you should follow the steps mentioned below in the same order-

  1. Immediately turn off the Type S jump starter.
  2. Unplug the jump starter from the vehicle by disconnecting the jumper cables.
  3. Wait for a few minutes and try again with the jumper cables connected in the correct order.
  4. Try to jump-start your car battery again and see if it works. This is to see if the jumper cables got damaged or not.
  5. After jump-starting, check both the car battery and the jump starter battery with a load tester.
  6. To use a load tester, access the battery compartment by turning off the unit and removing its cover. 
  7. Once you have access to the battery, connect a load tester to the battery terminals and turn it on to apply a load.
  8. 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 has been damaged and needs to be replaced.

If the error message persists after correcting the cable connections, there may be an issue with the jump starter itself. In this case, you may need to contact the manufacturer for further assistance or consider getting a replacement jump starter.

Note: You should be aware of the official specification of how long it takes your Jumpstarter to charge. It’ll help you to bring the most out of your device.

Damage to Components:

  1. A spark can occur, causing a sudden surge of electricity that can damage sensitive electronics and other electrical components in both the jump starter and the vehicle.
  2. The electrical system may be damaged, including sensors and fuses.

Damage to Battery:

  1. If the connection persists for a while, the electrical current doesn’t have anywhere to go, and damage to the battery is likely to occur.
  2. Heat is created, gases are generated, and dangerous situations can occur.
  3. In this case, hydrogen gas could be discharged, and if gas escapes, it could explode.

Damage to Jumper Cables:

  1. Incorrect contact with a jumper cable between two batteries for a time will heat your jumper cables.
  2. The wires will heat up and may get damaged.
  3. Strong cables may handle the heat better, but some lightweight cables could start to melt/burn when exposed to this amount of heat.

Damage to Alternator:

If a car’s components are on during the jump start, the alternator can receive a surge of power that may cause damage to it.

How to Maintain Your Type S Jump Starter?

Maintaining your Type S jump starter is important to ensure that it will work properly when you need it most. Here are some tips to keep it in good condition.

  1. Regularly Charge the Battery: Ensure that the jump starter is fully charged before using it. After use, charge it again and store it in a cool, dry place.
  2. Check Battery Condition: Periodically check the battery’s condition and ensure that it’s still holding a charge. If you notice any issues, contact the manufacturer for assistance.
  3. Clean and Inspect Connections: Regularly clean the connections and inspect them for any signs of corrosion or damage. If you notice any issues, clean the connections with a wire brush and contact the manufacturer for assistance.
  4. Check Cables: Inspect the cables for any signs of damage or wear. If you notice any issues, replace the cables with new ones.
  5. Store in a Safe Place: Store the jump starter in a cool, dry place, away from direct sunlight and moisture. Avoid storing it in extreme temperatures.
  6. Use the Correct Charger: Use only the charger that came with the jump starter or a charger recommended by the manufacturer. Using an incorrect charger can damage the battery and void the warranty. Also, charge the jump starter fully before using it.
