You’re out on a hike, and your phone dies. You didn’t bring a portable charger, so you’re stuck without any way to communicate with the outside world. To make matters worse, your car is parked at the trailhead, and you have no way to get back home. If only you had remembered to charge your lead acid battery before you left!
If you’re like most people, you’ve probably experienced the frustration of a dead battery. But what you may not know is that overcharging your lead acid battery can be just as damaging as not charging it at all. In this article, we’ll discuss what overcharging is, the dangers it poses to your battery, and how to prevent it.
What is overcharging?
Overcharging can mean a lot of different things depending on the context in which it is used. Most commonly, it refers to instances where someone is charged too much money for a good or service.
This could be because the person doing the charging has deliberately inflated the price, or because they have made a mistake and overcharged by accident.
In either case, it can be frustrating and costly for the person who has been overcharged. In some cases, overcharging can also refer to filling something too full, such as a battery or a gas tank.
This can damage the item being filled and lead to problems down the road.
Finally, overcharging can also refer to exaggeration. This is often seen in cases where people are trying to sell something, and they make false or exaggerated claims about the item in order to get people to buy it. Whatever the context, overcharging is generally seen as a bad thing.
Overcharging occurs when a lead acid battery is charged beyond its recommended voltage. This can happen if you leave your battery plugged in after it’s already full, or if you use a charger that isn’t compatible with your battery. When this happens, the excess electricity causes the lead in the battery to oxidize, which reduces the battery’s capacity and can shorten its lifespan.
The dangers of overcharging
Overcharging your lead acid battery can cause a number of problems, including reduced capacity, shortened lifespan, and decreased performance. In extreme cases, overcharging can even cause the battery to leak or explode. That’s why it’s important to be aware of the dangers of overcharging and take steps to prevent it.
How to prevent overcharging
Fortunately, there are a few simple things you can do to prevent overcharging your lead acid battery.
- First, make sure you’re using a charger that’s compatible with your battery.
- Second, don’t leave your battery plugged in after it’s already full.
- And finally, if you’re not using your battery for a long period of time, make sure to disconnect it from the charger.
By following these simple tips, you can help ensure that your lead acid battery stays healthy and lasts for many years.
Also, you can use a circuit to protect the battery charge.

8 Tips for Safely Charging
Don’t overdo it.
To make batteries last longer, it is important to unplug them when they are fully charged. When a device or battery is plugged into a charger after it has been fully charged, this is called overcharging. Overcharging a battery can make it last less. Battery University says that nickel- and lithium-based batteries should be stored with a 40 percent state-of-charge to keep the battery in good working condition and allow it to self-discharge. If you follow these simple tips, you can make your devices and batteries last longer.
Be present.
Being there is one of the most important things you can do to keep your home safe from fire. This may seem obvious, but it’s important to say it again. If a fire starts, the faster you find out about it, the faster you can put it out. But your presence can make a huge difference even if you can’t stop a fire from starting. Even if you’re not home, a working smoke detector can tell you about a fire, and a fire extinguisher can help you put it out before it does too much damage. So, if you’re ever not sure if you should leave your home unattended or not, remember: it’s always better to be there.
Stay away from flammables.
As anyone who has ever dealt with a house fire knows, flammable materials are a major hazard. Even something as simple as a pillow can easily ignite, sending flames racing through a home in seconds. That’s why it’s so important to be careful when charging devices or batteries. Always place them on a non-flammable surface, such as a table or countertop. If possible, keep them away from direct sunlight and make sure there is good air circulation around them. By taking these simple precautions, you can prevent smoke and fire from damaging your home and putting your family at risk.
Don’t be extreme.
In today’s world, it seems like we are always being asked to go to one extreme or the other. We are told to eat low-fat or no-fat, high-protein or all-protein, and the list goes on. But when it comes to batteries, the experts say that moderation is key. Rechargeable batteries are often exposed to unfavorable temperatures, and extreme temperatures can shorten expected battery life. So if you want your batteries to last, store them in a cool place whenever possible. The recommended storage temperature for most batteries is 15 °C (59 °F), according to Battery University. This temperature keeps the battery in working order and lets it self-discharge while keeping capacity loss to a minimum. So next time you’re thinking about extreme measures, remember that sometimes the best course of action is simply to take it easy.
Choose the right way.
Rechargeable batteries should always be charged in the device they are used in, in the charger that came with the battery, or in a charger that the manufacturer recommends. Chargers are made for specific types of batteries; mixing chargers and batteries could cause problems you didn’t expect. If you want to charge your device or batteries in a different way, check the manufacturer’s website for instructions.
Don’t mix.
Don’t put both rechargeable and disposable batteries in a charger at the same time to charge them. Alkaline batteries that you throw away can’t be charged, so you should never put them in a charger. Manufacturers also say that you shouldn’t put batteries from different brands into the same charger. To avoid any risks, each brand should be charged separately.
Take care of the dead.
What do you do with batteries that are no longer working? Keep them in a cool, dry place in a container that isn’t made of metal until you know how to get rid of them properly. The Environmental Protection Agency (EPA) suggests putting electrical tape on the ends of used batteries or putting each one in its own plastic bag. If the ends of two wires rub against each other, a spark could happen. Don’t put batteries that aren’t in a battery holder in a drawer or other place where they could touch metal objects like paper clips or steel wool.
Please, please, please recycle!
Don’t throw away your old rechargeable batteries. They will be thrown out right away. Before you throw away an electronic device, you should take out the rechargeable batteries. Most places that recycle electronics don’t recycle batteries separately. Make sure they go to a battery recycler for processing to make sure they are recycled the right way.
Call2Recycle makes it easy to recycle rechargeable batteries. Just go to our website locator and type in your zip code to find the closest public recycling location on our list. Many cities and towns also have programs for recycling batteries, either at the curb or at their hazardous waste/recycling centers. By using Call2Recycle to recycle your batteries, you can be sure that the byproducts will be used to make new products, like new batteries, steel alloys, and cement additives, and nothing will end up in a garbage dump.
Be Safe.
Think twice the next time you want to take a shortcut when you store, charge, or recycle your electronic device. The U.S. Consumer Product Safety Commission has a long list of battery-related problems that have happened while an electronic device was being used, put away, or charged. By taking a few simple steps and using common sense, you can keep yourself safe from possible dangers and get more use out of the batteries in your portable devices.
FAQs
Can you overcharge a 12-volt lead acid battery?
Overcharging a battery can shorten its life. If the charging current is high, the battery can get too hot, but this won’t happen if the charging current is low.
What happens if a battery is overcharged?
When a battery is overcharged, it gives off too much gas. The electrolyte gets hot, and both hydrogen and oxygen gas are made. On older batteries with vents, the electrolyte could cook away, leaving the plates uncovered and broken. If gas builds up inside a sealed battery, the battery could burst.
What causes the battery to overcharge?
You can also overcharge your battery by making a mistake. This can happen if you don’t know how to use a car battery charger, if you set the amps too high, or if you set the voltage wrong. If you leave your car battery charger alone overnight, it can also get too charged, which can hurt your battery.
What are the symptoms of an overcharged battery?
Damage to an overcharged battery shows up as swelling and cracks in the battery case. This is because gas builds up inside the battery and electrolyte fluid leaks out. When a battery has been charged too much, it usually feels hot when you touch it.
Conclusion
