#12v deep cycle batteries how to
How to avoid your battery from being overcharged That means if your charger or is giving out say 17V, then your battery will keep charging past the 14V that it was designed to hold.įor more info on battery, capacity and cells, visit my post on the difference between 6v and 12v RV Batteries. Since a battery is not smart and just a bunch of battery plates and lead acid, it will keep taking that charge as it tries to get to equilibrium with the power source. What happens if we have a charger that is not working correctly and is giving out higher voltage?
We reviewed that a charging system will provide 14V to a 12V battery to keep it fully charged. Since we know that a battery can be overcharged, let’s now see how that can happen. Let’s get back to the question of overcharging the battery. Other principles come into play, like amps, but in terms of volts, that is a good difference to note. Usually, a good charge battery charge rate is when there are 2 more volts from the battery to the charger. The voltage supplied by your charger is around 14V, giving added voltage to your 12V battery. A charger gives your battery power while driving your truck or having your RV plugged in. When you charge your battery, you are connected to a truck engine (car battery) or plugged into shore power (your RV battery). Chargers and Alternators give over 14V to charge the battery Eventually, the batteries will become equally in voltage once the difference in power is transferred from one battery to the next.

So if you have a fully charged battery at 14V and connect it to a weak battery with 10V, power will be transferred from the full charge battery to the weak battery. And that transfer of power, in simple terms, is higher voltage going into a battery with lower voltage. So how does a battery get overcharged? Good question, but let’s first look at how a battery charges, and then we can see how it can be overcharged.Ī battery is a simple transfer of power from one source to another. The resulting gas created from this process is highly flammable and could lead to dangerous situations if not addressed quickly. Additionally, extreme heat may boil off the electrolyte stored inside the battery. This can cause the cells to start breaking down – leading to various issues, including corrosion of the terminals and damage to internal parts. When a battery becomes overcharged, its cells become exposed to too much energy and heat. What is OverchargeĪn overcharge on a 12V system is a voltage on your battery greater than 14.4V. Is anything over 12V considered overcharged? The answer to that is “no.” A battery can safely hold around 14V and is not considered overcharged. Most of these batteries are considered fully charged when around 14.4V at rest. The charge voltage is the amount of electricity that must be present in an electrical system to be considered “fully charged.” In a 12V battery, you will likely get more than that amount of voltage. As we review the potential for overcharging, the same principles apply to the following battery type:Īll of these batteries are 12V and can be charged and re-charged with the potential of being overcharged. They are lead-plates set in an acid solution and produce 12V of power. These are flooded batteries that have been around for decades. We are referring to the batteries we all use for boats, cars and RVs. However, knowing how battery voltage works, you can watch for issues and signs of your battery being overcharged. But can that power be overcharged to where it will damage the battery or reduce battery life? As you read above, “yes” it can be overcharged. After all, a battery is a method to store power.
When we refer to overcharging, we are talking about going above the battery’s capacity to safely and effectively hold a charge. Final Thoughts How a Deep Cycle Battery Can Be Overcharged.How a Deep Cycle Battery Can Be Overcharged.The information below applies to all kinds of cell batteries, including a marine battery, AGM battery, or even lithium-ion. How to avoid your battery from being overchargedĪs a side note, this post relates to all types of 12V batteries that you can use for your boat, RV, or trailer.How a deep cycle battery can be overcharged.This post will review how deep cycle batteries can get overcharged and how you can to avoid it.
However, things must go wrong for your battery to get more charge than desired. Can you overcharge a deep cycle battery? The short is “yes”, it is possible to overcharge.
