Trickle chargers are considered to be useful battery chargers that are different than the regular ones. They charge at really low amperages, which is something that an adjustable jump starter can do, as well. So your question probably is: why invest in a trickle charger if there are already other devices that can do its job? The thing is, there is more to it.

First of all, it is important to understand the difference between a trickle charger and a normal car battery charger. Trickle charges are only capable of putting out a very low amperage, while normal jump starters can put out some of the highest values. Trickle chargers can put out usually between 1-3 amps, with the purpose of maintaining a car battery fully charged. This type of device was designed for lead acid batteries that, studies say, have a longer life span and better health if charged slower, rather than faster.

The truth is that trickle chargers aren’t crucial accessories to have. They target those who are obsessed with fine tuning and who are really passionate about this matter.

Nowadays, there are a lot of trickle charger models on the market. Some include really advanced technologies, while others are basic. Depending on your needs and your budget, you can find one that satisfies your requirements.

If you are looking to buy the best trickle charger within your budget in the near future, but you aren’t convinced which model is worth paying for, then the below list might be of help. We have selected 5 of the best-selling products on the market and highlighted their pros and cons for you. We have taken into consideration personal observations and consumer feedback while compiling the list, so that you can have the best options right in front of you. Take a look at the below products.

Questions and Answers

What are the benefits that trickle chargers offer?

Trickle chargers are devices that belong to the same category of tools as battery chargers. The difference between them is that trickle chargers charge low capacity batteries and are capable of maintaining them. They are known for their capacity to extend a battery’s life, too. Unlike regular battery chargers that are very powerful, these devices can be left connected to the batteries for a long time, without damaging them. As you probably already know, batteries discharge when not used for a long period of time. When that happens, sulphide forms inside them, which is why they start to malfunction. If you are worried that this might happen, it is essential to know that trickle chargers can prevent them from becoming sulphated. 

These devices get the energy from electricity. When they are connected to an outlet and then to the battery, they convert electricity into power, slowly, minimizing the chances of damaging them. More importantly, these chargers have battery regulators integrated that prevent overcharging. The main advantages of trickle chargers over battery chargers are that they are suitable for charging all day long, the energy is transferred in a steady trickle and the battery life is prolonged, as no sulphates form inside.    

How does a battery charger work?

Battery chargers are different than trickle chargers and are used differently, too. They have a circuitry that monitors the battery and only charges it when the voltage drops under a preset level. This level varies from manufacturer to manufacturer, but as a general rule, you should know that battery charger enable the charger to shut off, in order to ensure that there is no minimum supply of energy to the battery. These devices work by driving electrical current to the battery, either directly from an integrated power source, either from an outlet. Regular battery chargers need AC power that is converted to DC current at a low voltage. Most modern products come with overcharging protection, but this doesn’t mean that you can leave it connected for long, unsupervised, as it is the case when using a trickle charger. 

Trickle charger vs battery charger

If you need a battery charger, either for your car’s battery or for the appliances and devices in your home, you should do some research before actually ordering one. Doing this helps you determine which the right kind of charger for your needs is. In some cases, charging a battery too fast can lead to full damage, while in other cases quick charging is exactly what you need. The main difference between these two charger types is that trickle chargers help you charge a battery extremely slow, ensuring the process is steady and safe, while battery chargers are designed to do it fast and efficient. If you need a type of product that can help you charge your devices right there and now or if you want to have it at you disposal when the car’s battery discharges accidentally, a regular battery charger is what you need. If, on the other side, you want to maintain the battery and prolong its life, then you need a trickle charger. 

Final Words

Trickle chargers guarantee the slow charge of a battery, helping you avoid any damage that could be caused in the process. Experts say that most battery explosions happen when charging them fast, using high amperage. By comparison with regular jump starters, trickle chargers work at a relatively slow and steady rate. These devices are ideal for vehicles that are put aside during the cold season, such as motorcycles.

Depending on your needs and preferences, you can buy a manual or an automatic trickle charger. In a world that is led by technology, everyone prefers to buy automatic accessories and tools, but that doesn’t mean that they don’t have their advantages.

Although this is the safest way of charging a battery, remember that it is also a very slow process. A fully discharged battery takes about 20 hours to charge, depending on its size. No matter what you choose for your car, make sure that you put safety first.
