What is an ATV Battery?

ATVs are operated by Powersports batteries similar to those used in motorcycles. The majority of ATV batteries are lead-acid batteries. Such ATV batteries are not suitable for ATVs, which are not designed for common roads or environments. Purchase a good quality digital smart charger to use with an ATV battery.

Different Types of ATV Batteries

We have found three different types of batteries. ATV users can choose from three different types of power sports batteries:

Flooded Lead Acid

An electrolyte that can move freely inside the battery container is featured in flooded lead-acid batteries.

AGM or Absorbed Glass Mat

The electrolyte solution in this battery is wicked between the battery plates by an innovative glass mat divider.

Lithium Iron Phosphate

A form of lithium-ion battery known as a lithium-iron-phosphate battery, also known as a LiFePO4 battery or an LFP battery, employs lithium iron phosphate as the cathode material to store lithium.

How do you check an ATV battery?

  • Battery testing is helpful in figuring out how much charge is still in your battery and whether or not a new battery needs to be purchased. 
  • Use a voltmeter to determine the battery’s state of charge for an AGM battery, or a hydrometer to determine the battery’s charge percentage.

How do I know if my ATV battery is bad?

A bad ATV battery will indicate some sign of negativity. Therefore, you should detect some facts that say you must change the battery. Let’s check out what ensures a bad battery.

  • Your car’s performance will show you if the battery needs to be replaced.
  • The battery is dying if it stops holding a charge as long as possible between charges.
  • A poor battery will make the lights dim, cause trouble powering the headlights, and make it challenging to run the car properly.
  • Bulges, fractures, and deterioration are all signs of a bad battery.
  • The voltage reading is a crucial part. The positive and negative battery terminals should be connected to the multimeter. Remember, a faulty battery can be present if your voltage is below 12.6 volts.
  • If you observe that the battery cannot charge to 10.5 volts, it either has a dead cell or is sulfated when you notice the voltage is 12.5 volts or less.
  • Also, a voltage that falls below 5 while your engine is running ensures the battery is defective and needs to be changed.

Why do ATV batteries not last?

  • All-terrain vehicles usually come equipped with lead-acid batteries, which might weaken because of the electrolytes in the battery. 
  • A short might result from the lead plates in your battery corroding in the air around them.
  • The lifespan of a battery might be shortened if it is left unused for extended periods of time.
  • An outdated battery can be an issue.
  • Sometimes, low battery conditions or the battery are no longer able to hold a charge disturb the entire system.
  • Additionally, you might need to replace the stator, or fluid levels are low, indicating that the battery will soon fail.

What factors affect an ATV battery’s lifespan?

how long does an atv battery last

The battery’s longevity is often influenced by storage temperature and charge level, the intensity of each discharging process, the regularity of riding, and the rate of riding a bike. The ATV battery is also impacted by additional information such as the environment, usage, and internal components. Let’s talk about this in detail.

System of Charging

There is a built-in power source on every ATV. Electric winches, EPS recognized as electric power steering, and heat grips all use too much battery power. Therefore, if your system is malfunctioning, your battery won’t be fully recharged, which shortens its lifespan.


It’s crucial to keep an eye on the charging process to avoid overcharging. It reduces the electrolytes that ultimately cause acid to evaporate. If this level falls low, your lead plates will be open to the air and will deteriorate.

Level of Battery

The battery level works to let you know about the leftover charge that exists until the battery runs out. Never allow the battery to go entirely flat. Otherwise, the battery will suffer damage and eventually die.

Environment Plays a Great Role

A battery’s lifespan can be greatly influenced by the environment or climate. Any battery functions best when it’s at a standard temperature. 20 to 22 0C, or 68–72 0F, is considered the norm for room temperature.

A lead-acid battery’s electrochemical reaction occurs more rapidly than usual in high temperatures, such as those above 30 degrees Celsius, which injures the battery tender and causes rapid battery drain. Additionally, it causes the battery to dry up and speeds up the internal deterioration that eventually causes the battery to fail.

If the temperature is below 0 degrees Celsius, low temperatures can also be to blame for battery death. CCA, or Cold-Cranking Amperage, is the amount of current a battery can output for 30 seconds at -18 °C while maintaining a cut-off voltage of at least 7,2 volts. That’s what you need to know!

The battery lifespan will decrease if you don’t ride the bike for a long time, if the temperature is cold, or if it’s winter, as these conditions put an enormous amount of stress on the battery. You might also notice the lead-acid battery’s electrochemical reactions are slowed down, and you can even notice that the electrolytes inside freeze, which reduces the lifespan of the ATV battery.

Usage of Battery

If you use them frequently, your battery will remain functional. The battery gets drained and recharged more frequently, though, when it is used quite often. As a result, if your ATV battery has been sitting idle for a while, you will need to take extra care to keep it charged.

Battery Water Loss

Do you know? Battery acid or electrolyte water will evaporate when the battery is overcharged. As we mentioned previously, the low level caused the plates to be open to the air, which caused them to rust. Therefore, wrap the lead plate in a cover. Also, when you have a decent smart charger, don’t worry about evaporation issues with sealed AGM or GEL batteries.

Internal sulfation of Battery

In a lead-acid battery, sulfation is the buildup of crystals on the lead plates. Sulfation buildup can quickly harm batteries, so keep it limited by carefully charging any battery. Therefore, all that is required of you is checking the electrolyte level, ensuring appropriate charging, and either storing the battery in a low state or letting it run completely flat.

How durable are conventional flooded lead-acid ATV batteries?

  • For most power sports drive systems, flood batteries with lead acid are long-lasting and reliable.
  • A conventional lead-acid battery can last for on average 2-3 years.
  • However, with good maintenance, they can last for 4-5 years.
