How long does it take to charge an ATV battery

The charging time depends on two things, the size of the battery and the type of charger you are using. Summing these two things together, it can take 4 to 20 hours to fully charge an ATV battery.

  • Charging a small battery with a 1.5 to 2 amp charger will take 3.5 to 4.5 hours for getting fully charged.
  • On the contrary, using a 5 amp charger on the same battery will extend the charging time up to 10 hours approximately.
  • The bigger battery of 12 volts will take 12 to 14 hours to get fully charged if you are using a 2 amp charger.
  • However, it will take around 20 hours for the full charge because of using a 5 amp battery.

Another thing that reduces the charging time a bit is the automatic float mode.

You need not skip this buying guides

If you select the battery charger for your ATV after reading the buying guide section carefully, I can assure you the product will be a value for money product with the best possible performance.

Type of batteries you have

You need to check out what type of battery is used in the ATV you have and then choose a charger that is compatible with the battery. A battery charger can go with lead-acid batteries, lithium-ion batteries, AGM, gel cell, wet cell and other types of batteries. But you have to check out the compatibility before purchasing.

Charger voltage

Typically battery charger nowadays is compatible with 12 volts charger. Most of the chargers operate through an automatic charging process from 1 or 2 volts. However, some chargers offer force charging from 0 volts.


It’s a crucial factor to consider before buying any automotive products. The charger should be equipped with float mode that automatically switches the charging process to that mode when it is fully charged and this prevents overcharging. There should spark-proof protection, overheating protection, reverse polarity protection, temperature protection and short circuit protection as well.

Ease of use

It won’t be a great thing to start the charging process after a long period o setup. That’s you need to buy a charger that comes with clamps and adequate connector cables. Also, it will be a great addition if there are built-in indicator lights to show the charging process, full battery charge, defective batteries, etc things. Some high-grade chargers come with thermal sensors to let you know about climate change.


As ATVs are used off-road and in rough weather conditions, you might have to recharge the battery on your way. So try to purchase a battery that is water and dust resistant to make it a perfect on the go ATV battery charger.

ATV battery voltage and amp

Most of the ATVs come with 12 volts of battery. However, the number is not accurate when it is fully charged. A fully charged ATV battery can produce voltage from 12.6 volts to 12.8 volts. However, it is better to use a charger that can produce 1.5 amp current for fast possible charging. Meanwhile, a 5 amp charger will only extend the charging period and if you use 5+ amps, there is every possibility of damaging the battery.

How to charge an ATV battery
