10 Reasons That Causes a Dead Atv Battery

1. Battery Is Too Old:

One of the main reasons that batteries die is simply because they are too old. Over time, the chemicals inside the battery break down, causing it to lose its ability to hold a charge. If your battery is over three years old, it’s probably time for a new one. The old battery is probably not holding a charge as well as it used to.

2. Lack of Use:

Another common cause of dead batteries is lack of use. If you don’t ride your ATV very often, the battery will slowly lose its charge over time. This is because the chemical reaction inside the battery only occurs when it’s being used.

3. Leaving the Lights On:

One of the quickest ways to kill a battery is by leaving the lights on when the engine is off. This drains the power from the battery, causing it to die. If you do this often, you’ll probably need to replace your battery more frequently.

4. Corroded Battery Terminals:

If the battery terminals are corroded, it can prevent the electrical current from flowing properly. This can cause the battery to die prematurely. To clean the terminals, use a wire brush to remove any corrosion. You can also try using a battery terminal protector to help keep the terminals clean. Unfortunately, the corroded terminal can also kill a battery.

5. Overcharging:

If you overcharge your battery, it can cause the chemicals inside to break down, causing the battery to die. It may also happen that the overcharging will cause the battery to leak, and this will damage your ATV. If the battery starts to leak, it’s time for a new one. Be sure to check the charging system regularly to avoid overcharging.

6. Damage from Heat or Cold: 

Extreme temperatures can also damage your battery. If it gets too hot or too cold, it can cause the chemicals inside to break down, causing the battery to die. It’s essential to store your ATV in a cool, dry place to avoid this. If you live in an area with extreme temperatures, you may need to invest in a battery designed to withstand those conditions.

7. Sulfation in the battery:

Sulfation is a common problem that can kill a battery. It occurs when the lead sulfate crystals inside the battery grow too large. This inhibits the flow of electricity, causing the battery to die. To prevent sulfation, be sure to keep your battery properly charged. If you let it discharge too far, sulfation will occur.

8. Loose or Dirty Battery Connections:

If the connections to your battery are loose, it can cause an electrical short, which will kill the battery. Be sure to check the connections regularly to make sure they are tight. Also, if the connections are dirty, it can prevent the electrical current from flowing properly, causing the battery to die. Clean the connections with a wire brush to remove any dirt or corrosion.

9. Short Circuiting: 

If you accidentally short circuit your battery, it can damage the internal structure, causing it to die. Short circuits usually occur when the positive and negative terminals are accidentally touched together. To prevent this, be sure to keep the terminal covers on tight. If the terminals do become exposed, make sure not to let them touch.

10. Wiring Problems:

If there is a problem with the wiring in your ATV, it can cause the battery to die. Check the wiring regularly for any frayed or exposed wires causing the problem. If you find any, replace them immediately. Also, make sure that all of the connections are secure and there is no corrosion on the battery terminals.

Step by Step Guide: How to Fix a Dead ATV Battery
