A Jump Start Isn’t The Only Way To Recharge A Car Battery And It’s Not Necessarily The Best Way Find Out How To Charge A Car Battery The Right Way

You can recharge a car battery when your car refuses to start. On average, most batteries do not require a recharge for at least five years. That’s if you’re taking good care of your car. Frequent recharges indicate that your car battery is of poor quality or that you are not taking care of your car as well as you should. Some batteries have a charge indicator where you can find out the state of the battery. If the indicator is clear or yellow, you have to recharge it.

Here are a few simple guidelines on how to recharge your battery yourself.

Note: Since battery acid is hazardous, be sure to take adequate precautions when handling old battery terminals to protect skin and clothing.

Use a Trickle Charger This device delivers electricity to your battery from a power outlet in a slow, steady stream. You don’t need to charge your car fast. A slow charge is much better, as batteries tend hold the charge for a longer period of time with this method. The trickle charger has an electric cord with a plug and two jumper cables with alligator clips.

Turn on the Charger Once both the terminals are connected, connect the charger to the electric outlet. Turn on the current and the battery will charge itself. Leave the charger on overnight. In the morning, turn off the charger and then check the reading on it. If the reading is less than an ampere then you can unplug the charger.

Length Of Time Using 10 Amps

A 10-amp charger is able to charge a half-discharged small car battery in about 2-3 hours. The small car battery is categorized as an RC 40-60. The charger can charge a 50% discharged medium-sized battery, which is RC 60-85, in about 3 to 4 hours, or a large-sized battery, which is RC 85-190, in approximately 4-7 hours. If the battery is fully empty, then you just need to double these times to see the amount of time your charge will take.

What Is A Linear Battery Charger

The linear battery charger is the simplest charger you can get. It enables you to recharge your cars battery via the plug-in at a wall socket.

It requires little set-up and power but the charger operates at a low amperage meaning it can take a long time to charge your battery and, depending on the amperage, it could take up to 12 hours to fully charge the battery.

The linear battery charger runs at a continuous charge, and doesnt have a controller to stop the charging when the battery is at full power so there is always a danger that you may overcharge your battery and damage it.

What Is The Best Speed To Charge A Car Battery

The speed of your car battery charging should depend on what you want to acquire. Fast charging can damage your;battery and will make its life shorter. Long-time charging with low amps is the best for keeping the batterys lifetime long.

Usually, a standard car battery charger is giving out 4-15 amperes. 2-4 ampere is typical for maintenance charging, and it will take around 24 hours to fully charge a dead battery at this load. Check your car battery charger for any settings for the charging rate and apply the charging rate for your needs.

To charge your car battery quickly, without damaging your car battery, I would recommend charging your battery at the rate of 8-15 amperes. Charging your battery over 15 amperes can damage your battery if you are unlucky and make the lifetime shorter.

Why Batteries Go Bad

A number of issues can take place within your cars battery that reduces its battery life.

Issues such as electrolyte loss or poor charging can lead to battery sulfation. When sulfation occurs, a battery loses some of its natural ability to convert chemical energy to electrical energy.

This stems from a batterys inability to perform the necessary chemical reaction between its acids and active materials to the degree that it once could.

When this occurs, issues with poor engine cranking often become evident and your battery will stop recharging itself properly.

This is the point at which many consumers discard their old battery in favor of a new replacement.

However, this can lead to excess expenditure that can often be avoided if you learn how to recondition batteries to give your car’s battery the longest battery life possible.

How Long Does It Take To Jump Start A Car Battery

If your car has died and you need to make it to the auto body shop, then jump starting your vehicle could be the best solution for a short-term fix. When your car dies, it is a sign that the battery is experiencing issues. Either the battery is just dead, or there is other damage that has made its way to the battery itself. You need to determine if your car battery is under warranty to see if you are covered.

One crucial part to note is that after you jump start a car to get the battery running, it can put added stress on the alternator. The alternator must provide electricity to the car and is simultaneously trying to recharge a dead battery that might need replacement. This puts a tremendous amount of stress on the alternator, and can in turn, damage the alternator along with the already-damaged battery.

A jump-started car can usually run for about 10-15 minutes after getting jumped, but your car alternator can undergo serious damage during that short period of time. Replacing an alternator is more expensive and time-consuming than just replacing a battery. Jumping a car can get you out of a tricky situation, but it can lead you into an even tougher one if youre not careful or jump your car too often.

Every time a driver turns the ignition key or presses the Start button, the starter motor is expected to crank the engine. This mechanism is caused by the;12-V flooded lead acid car battery, which is standard on virtually every vehicle on the road. Some cars carry a second battery, and trucks and RVs may carry a battery bank, linking several batteries. Similar batteries can be found in tractors, power equipment, motorcycles, powersports machines, snowmobiles, four-wheelers, and solar power backup systems, to name a few.

Car batteries tend to last for several years, but lifespan depends on how they are used. The typical car battery, driven every day, properly charged, and never deep-cycled, could last upwards of 7 years, but thats a best-case scenario. Most maintenance-free car batteries tend to last 4 to 7 years. Short car battery life, less than 3 or 4 years, can be related to several different problems, such as lack of use, corrosion, excessive deep cycling, electrolyte evaporation, damage, or charging problems.

Step 2 – Remove Battery Caps

You will now remove the caps at the top of your batterys casing.

This will allow you to gain access to the battery cells and battery plates. On some batteries, this requires the removal of two side-by-side rectangular caps.

On other batteries that are deemed to be maintenance-free. Six individual caps can be located under the battery’s data sticker.

Simply peel up the sticker to reveal the caps. No matter the style of cap, removal can be completed by gently prying with the use of a small flat head screwdriver.

Step 3 – Mix Water Solution

In the majority of situations, you will find that the fluid level in each cylinder is slightly low. This will be remedied by adding a solution consisting of Epsom salts and distilled water.

Simply pour ½ liter of distilled water into a suitable container. Next, add as much Epsom salts as can be completely dissolved within. Heat this mixture to an approximate temperature of 150 degrees Fahrenheit.;

How Long Does It Take To Trickle Charge A Car Battery

Trickle charging your car might arguably be the best solution for long-term use, since it is used over a long period of time to regularly maintain the battery levels without an extreme amount of power. This is the preferred method to keep your car battery topped off if you dont drive the vehicle consistently as well. Those who drive RVs, ATVs, and motorcycles generally prefer trickle chargers.

Trickle chargers can take upwards of 2 days to charge a car battery to the full amount. A trickle charger generally only uses 1-2 amps, so the process is a lot slower than a higher-amperage charger. The best part about the trickle charging mechanism is that it wont overcharge the battery by accident. It also prevents the battery from potentially overheating due to a high amount of power and voltage. If you have a damaged battery or an old battery that wont charge, you can bring it on specific place for some compensation especially if youre in Nashville.

In order to determine how much time it will take to trickle charge your car, you need to read the spec sheet and possibly buy an automotive battery tester to see how much your battery has left. If you dont have a car battery tester, you can calculate the time using the minutes left in your battery, the reserve capacity in terms of amp hours, the voltage used, and the current battery percentage.
