The Ugly Truth About Why Powersports Batteries Fail So Easily!
Traditional Flooded Acid Batteries: Acid Stratification and Sulfation
Acid stratification is something that can happen inside the battery of your machine if you haven't made the switch to an AGM battery. Inside the battery, there is a liquid called electrolyte, which helps generate the electrical power. Sometimes, the electrolyte can become imbalanced and create layers or "stratification." Think of it like oil and water separating into different layers in a bottle.
When acid stratification occurs, the heavier acid sinks to the bottom of the battery, while the lighter acid rises to the top. This separation can cause problems because the battery needs a balanced mix of acid throughout to work properly. AGM batteries absorb the acid and electrolyte and therefore the acid and electrolyte cannot separate or leak out.
Sulfation is another common issue that can affect ATV batteries. It happens when the battery is left discharged or not used for a long time. When this happens, a chemical reaction occurs that forms small crystals on the battery plates. These crystals are made of lead sulfate.
Acid stratification can affect the performance of your ATV battery. The main issue is that the acid needed to generate electricity may not be evenly distributed. As a result, the battery may not hold a charge as well as it should. This means you might have trouble starting your ATV or find that the battery doesn't last as long as it should.
Sulfation can cause problems because it reduces the battery's ability to hold a charge. It's like having a layer of dirt or gunk on your battery's internal parts. When these crystals build up, they can interfere with the normal flow of electricity, making it harder for the battery to provide power to your ATV.
To prevent both stratification and sulfation, it's important to keep your battery charged. When your machine sits idle for a long time, the acid can settle and separate more easily. By regularly charging the battery or using a battery maintainer, you can help mix the acid and prevent stratification.
AGM Batteries: Improper Charging
When it comes to charging an AGM (Absorbent Glass Mat) battery, there is an Achilles Heel. AGM batteries require specific charging methods to ensure they perform optimally and last longer.
Firstly, it's crucial to use a charger that is specifically designed for AGM batteries. These chargers are equipped with the right settings and parameters to properly charge AGM batteries. Using a charger designed for other battery types may not deliver the appropriate charging profile and can potentially harm the battery.
Next, check the specifications of your charger to ensure it matches the voltage and capacity of your AGM battery. You'll want to make sure that the charger's voltage settings align with your battery's voltage. Mismatching the voltage can result in ineffective charging or damage to the battery.
When connecting the charger to the battery, it's important to connect the positive (red) clamp to the positive terminal of the battery and the negative (black) clamp to the negative terminal. This ensures a proper and secure connection for effective charging.
Modern battery chargers often have specific modes for AGM or gel batteries. Look for an "AGM mode" or "Gel mode" on your charger and select it before starting the charging process. These modes adjust the charging parameters to match the requirements of AGM batteries, ensuring they receive the right charging profile.
During the charging process, keep a close eye on the battery and charger. If you notice any unusual signs like excessive heat, strange odors, or anything out of the ordinary, it's important to stop the charging immediately and seek professional assistance. Safety should always be a top priority.
It's also recommended to charge AGM batteries in a well-ventilated area. Charging batteries can produce hydrogen gas, which is flammable. By charging in a well-ventilated space, you reduce the risk of gas accumulation and potential hazards.
Lastly, make sure to follow the recommended charging time for your AGM battery. Overcharging or undercharging can affect the battery's overall performance and lifespan. Refer to the manufacturer's guidelines or the charger's manual for the recommended charging duration.
Batteries are usually stamped on the outside with the maximum recommended charging amps and duration. Rapid charging with a higher than recommended amperage can harm the battery.
Why Are My Terminals Corroded?
Corrosion on battery terminals occurs when a chemical reaction happens between the metal terminals and the surrounding environment. Battery terminals are typically made of metal, usually lead or a lead alloy. When the battery is being used or stored, tiny particles from the air and moisture in the environment can react with the metal terminals.
The most common cause of corrosion on battery terminals is the reaction between the metal and sulfuric acid, which is the liquid inside the battery. This reaction creates a substance called lead sulfate, which appears as a whitish or bluish powder. Over time, this lead sulfate builds up on the battery terminals and can hinder the flow of electricity between the battery and the connected devices.
Other factors that can contribute to corrosion include exposure to high temperatures, high humidity, or contaminants in the environment. These factors can speed up the chemical reactions and increase the likelihood of corrosion.
To prevent or reduce corrosion on battery terminals, it is essential to keep the battery and its terminals clean and dry. Regularly inspecting and cleaning the terminals can help remove any buildup of lead sulfate or other contaminants. Applying a thin layer of petroleum jelly or a specialized terminal protectant can also create a barrier between the metal and the environment, reducing the chances of corrosion.
By taking care of battery terminals and keeping them clean, you can help maintain a good electrical connection and ensure the battery power gets to your starter. Don't do that and you'll be ready to shop for a new battery sooner than you think.
