The Difference Between A Trickle Charger And A Regular Battery Charger

How long does it take electrons to get from a car battery to the starting motor

A trickle charger provides a continues trickle of a charge to keep maintain your battery topped off without the risk of overcharging. They are designed to feed a low charge over a period of time to prevent discharge. However it should be removed to prevent over charging once the battery is completely charged.

A maintenance charger is the new terminology to denote a smart 2 amp charger that can stay connected to the battery and will automatically cycle off if once the battery is topped off.

Today, all of these are generally of the maintenance charger variety and old-timers tend to use the terms interchangeably or call them a battery tender.

The Difference between these two is that the regular models has higher amperage settings. they also have the circuitry to shut off when the charge is complete, or if the battery is overheating.

How To Recognize The Time For Car Battery Replacement

A well maintained battery will last at least 3 to 5 years under normal conditions. However, if it does need to be replaced, there are numerous indicators that you should look out for. Initial indication is a delayed start of the engine, which is caused by internal elements of the battery that have already been worn out. While driving, you may have electrical problems, which is the second indication. Consider the dimming of the front or rear lights, the malfunctioning of the radio, and the non-operational dashboard as examples.

If so, replace the battery.

Sandpaper can be used to clean the wires, but make sure to use gloves.

The battery may be damaged if you live in a climate with many seasons or if you are subjected to severe weather.

Charging Your Car Battery

If you havent been driving your car or its been left sitting idle, you may not have enough power in your battery to start the engine. And while it may seem like a good idea, running your vehicles engine five minutes a day is not enough to maintain your car battery.

To maintain the charge in your vehicles battery you need at least 30 minutes of driving – depending on the vehicle and the battery age. However, we recommend using a battery charger. With a fully automatic charger, it can be fitted to maintain your pride and joy or, used as a normal battery charger. Charge every two weeks and youll extend the life of your battery, restore battery performance and minimise the chances of breaking down.

The answer to the above question depends on the number of amps you are using for battery charging.

For instance:

  • 40-Amp Charger: 40 amps has a fast-charging capacity and can charge a car’s battery within a few minutes to an hour.
  • 2-Amp Charger: A battery charger with low amp charging, such as 2 amps, can recharge a battery in one to two days. This is because a 2-amp battery provides only 1 ampere per hour.
  • 4-Amp Charger: Generally, a car battery holds 48 amps, so using this amount of voltage will take up to twelve hours to reach full battery capacity.
  • 10-Amp Charger: A 10-amp charger can recharge a half-discharged small car battery within 2-3 hours and a medium-size car battery within 3-4 hours. A large car battery at 50% charge capacity takes 4-7 hours to reach full charge.

How Many Volts In A Fully Charged Car Battery

Most modern vehicles have a 12 volt battery underneath the hood. A 12 volt car battery contains six cells, each of which will contain 2.1 volts of power when fully charged. So, when the engine is off, a car battery is considered fully charged at 12.4 to 12.6 volts.

When your battery’s voltage drops even a small amount it can make a big difference in its overall performance. For instance, a voltage of 12.1 volts means your battery is operating at only 50% of its total charge. Once it drops down to 11.6 volts, the battery is almost completely discharged.

    This is a problem you might run into if you really let your car battery completely discharge. This type of battery is nothing but an overly heavy paperweight.

    Its usually an easy problem to remedy if you can get a jump from another car.

    The reason your smart charger wont begin the charging process is because of its built-in safety feature.

    Most smart chargers wont pass current through their cables until a minimum voltage is detected first from a battery. This is so that the charger wont attempt to pass on a charge if you hook the cables to the wrong terminals or whatnot.

    The 12-volt smart charger needs to detect a minimum voltage in the battery to begin charging . Safely connect jumper cables from a running car with a good battery to the fully discharged battery for a few minutes and rev the engine a little to increase amperage.

    Charging A Car Battery: 4 Things To Remember

    Charging your car battery on a regular basis is an effective strategy to keep it in good condition. However, there are four things you should keep in mind before connecting the charger to your device. Keep Your Battery Clean: Maintaining your batterys cleanliness is the most straightforward and efficient technique to ensure that it lasts as long as possible. The development of dirt and rust on the cable and terminals can impair the distribution of power output level and reduce the efficiency of the batterys internal battery.

    • The weather has a considerable influence on the battery and its charging ability.
    • When the temperature is too low, the batterys ability to provide its full potential power is compromised, while excessive heat reduces the capacity of the batterys ability to retain its charge by evaporating battery solutions.
    • When it comes to charging your automobile battery, it is not necessarily the alternators responsibility.
    • Recognize when you should rely on your alternator and when you should utilize a separate charger.

    Last but not least, always remember to switch off all of your in-car devices while youre charging them. Power-hungry gadgets are one of the most significant causes of battery draining, and using them while charging will prevent the battery from charging properly.

    How Long Does It Take To Charge A Car Battery With Another Car

    How to charge a completely dead car truck or motorcycle battery that won’t take a charge

    In order to answer this question, it is first important to understand how a car battery works. Car batteries are rechargeable, meaning that they can be used multiple times. The battery in a car is made up of lead plates and sulfuric acid. When the car is turned off, the alternator kicks in and starts generating power. This power goes to the battery and recharges it.

    The amount of time it takes to charge a car battery with another car depends on the size of the battery and the amount of power being put into it.

    For example, if two cars are trying to charge a small battery, it will take longer than if one car is trying to charge a large battery. It also depends on how much power the alternator in each car is putting out.

    How Long Does The Alternator Take To Charge A Car Battery

    If youve ever had a mechanic jumpstart your car, theyve probably told you to let it run for a bit before you turn it back off. Thats so the alternator can charge your battery, and you wont be stuck with a dead battery again as soon as you shut the car off.

    But how long is a bit, and when is it safe to shut your car off again? The answer to the question of how long to charge a car battery with your cars alternator isnt that simple.

    It really depends on how hard youre driving your vehicle. Your alternator is belt-driven, and your engines RPM directly controls the speed of the belt.

    The faster you drive, the harder your alternator can work. So, if youre driving down the freeway, your alternator can usually get your battery back to life within 30 minutes, but if your car is just sitting in the driveway, it might take a few hours.

    Its also important to note that your alternator is charging your battery like a 40-amp charger would, which means its dumping power into it as fast as it can. While this is effective at charging your battery quickly, it can cause it to wear out sooner.

    However, your alternator is like a smart charger. As soon as your battery reaches the correct voltage, it starts dumping the excess voltage to ground, meaning that you dont have to worry about your battery getting overcharged!

    How To Reduce Your Battery Charging Time

    The battery depth of discharge is one crucial factor determining your car battery charging duration. Recharging a fully discharged battery will most certainly take longer than one that still has a 50% charge. Discussed below are some tips to help reduce your battery charging time:

    Take longer trips: Driving short distances seems like a harmless activity, but it is a significant factor that impacts battery charge time. Short commutes dont give the alternator enough time to send an electrical current back to your battery to recharge as you drive. Continuous short trips gradually drain your battery until it loses all the charge and requires a longer charging period. Hence, if you want to reduce your charging time, you should favor long trips over short ones.

    Minimal use of electrical components on battery power: If you dont have your car engine running, you shouldnt leave your headlight, infotainment system, or any electrical component on. Unnecessary use of battery power is a sure way to drain its charge. Always ensure you turn off any equipment that could deplete the battery charge before exiting your car.

    Keep your battery clean: If the casing of your battery is covered with dirt, grime, or other greasy debris, your battery may discharge across it. This creates a form of a short circuit that eventually causes your battery to get flat quicker, resulting in increased charging time.
