How to Buy the Best ATV Batteries

Best ATV Battery
Best ATV Battery

1. Conventional or AGM Battery

A conventional ATV battery is usually a lead-acid battery that is quite popular and fairly affordable. On the other hand, an AGM battery is usually a heavy-duty battery that is significantly more expensive.

This type of battery is able to provide more battery power to your electric components and will be able to supplement your charging system with more power when necessary.

Additionally, since the ATV is usually used on rough terrains where there is a constant vibration occurring throughout the vehicle, it is best to go with an AGM battery since AGM has an excellent resistance to vibrations and shocks.

This is because the fiberglass sheets used in AGM batteries are very close together which nullifies the risk of those sheets moving inside the battery even when there are significant vibrations outside.

2. Compatibility

One of the most important aspects to consider when purchasing a battery for your ATV is compatibility. Indeed, your ATV is not compatible with every type of battery on the market. First of all, you need to consider the voltage and capacity of the battery.

You do not want to go with a battery that exceeds the manufacturer recommended specs. This will put a little pressure on your charging system and can close electrical failure.

Additionally, the enclosure for the battery is important as well. Not all batteries will fit the ATV enclosure as it usually has a fixed shape.

Therefore, you need to ensure that the battery you are interested in will fit your ATV. Checking through the manufacturer specs of the ATV battery should let you know if that particular model is compatible with your vehicle.

3. Battery capacity

As already mentioned, the battery capacity is another important aspect. You need to the right type of capacity for your ATV. If you go with an ATV battery that has a higher capacity than what your ATV charging system can provide, then you will be left with a battery that will always be undercharged.

On the other hand, if the ATV battery has a lower capacity, then your charging system will always overcharge the battery, causing a rise in temperature and a decrease in its lifespan. Not to mention that it can be a huge security hazard as well.

4. Cold Cranking Amps

In short, the cold cranking amps or CCA is a metric used for batteries to show how effective the battery is in cold temperatures. Generally, the higher the CCA value then the better it is for use in cold winters. If your ATV is usually left outside in the cold, then it is important that you consider the CCA value.

In most cases, a cold cranking amp higher than 500 CCA should guarantee that you will have no problem starting your engine even if the temperature is below zero.

5. Brand

You do not want to go with a no-name brand when purchasing a quad battery. This is because a branded battery will have a superior lifespan as it is made from higher grade materials. Additionally, you also get a form of warranty when going with a branded battery which is important.

6. Cycle Life

Basically, the cycle life is the amount of time that the battery can be recharged over and over again. Of course, you want the number of cycles for your ATV battery to be as high as possible.

In most cases, a cycle life greater than 3000 should ensure that you are getting a high-quality ATV battery that will last you a fairly long time.

7. Price

Despite the ATV battery being affordable, prices can quickly go up if you are not careful. Therefore, we recommend that you make a budget and stick to that budget when buying an ATV battery online. In any case, a good ATV battery should cost you less than $75.

Some Mistakes While Using ATV Battery

1. Capacity

The capacity of the battery will directly depend on the number of electric devices and lights that you have on the ATV. In most cases, the charging system is responsible for providing this type of current.

However, using a high capacity battery on an ATV equipped with many electric devices will result in a heavy load and the charging system will underperform when charging the battery.

Therefore, it is important to pay attention to manufacturers specs when replacing the ATV battery as every ATV has a specific battery capacity calculated by the manufacturer.

2. Adding Water to Wet Cell Batteries

Some ATV batteries are equipped with wet cell technology which means that they use distilled water for the electrolyte inside the battery. As with any wet cell battery, you need to perform regular maintenance to keep the battery in tiptop condition.

The problem is that sometimes people replace the distilled water in the wet cell battery with regular tap water. Regular tap water contains all sorts of minerals and heavy metals that dilutes the electrolyte and cause damage to the electrodes of the battery.

3. Under Charging

As with any type of battery on the market, undercharging a battery will cause the electrodes to sulfate over time. Indeed, most people who are charging the battery are usually in a hurry and want to use their vehicle as quickly as possible, and often times fail to wait for their battery to fully charge.

4. Over Charging

Similar to undercharging, overcharging the battery is also bad. Overcharging a battery usually, result in a rise of temperature that will cause all sorts of problem in the battery. In the worst-case scenario, overcharging can cause your battery to expand the casing and leak battery acid all over your ATV.

5. Not Charging in a Timely Manner

One of the most destructive forms of charging a battery is waiting for the battery to go at 0% and then charging it again back to 100%. The correct way is to charge the battery fully when it is around 20%. By doing so, you will get a greater lifespan for your battery.
