We all know that car batteries will have a tendency to lose charge after being used for a long time. But when it’s time to charge a car battery, you must know that charging faster is not the best thing to do. As charging battery at a high amperage can damage your battery or even results in a battery explosion. Luckily, you don’t have to worry about this situation anymore as nowadays we have the trickle charger – a savior to save the life of car batteries. Let’s check out this article to know what a trickle charger for car is and Top 10 best trickle charger reviews completed by auto experts.

What is A Trickle Charger?

First of all, you should know about trickle charging. Trickle charging is a method used to charge a fully charged battery at the rate that equal to its self-discharge rate, therefore allowing the battery to stay at its fully charged rate. This state only occurs when the car battery is not loaded, because trickle charging will not charge a battery if current is being drawn a load. A battery under continuous float-voltage ( the voltage that a battery is maintained after being fully charged) is said to be float-charging. According to auto experts, trickle charging is the most ideal for cars and trucks which are stored away during the winter time or for any car meant to be used for urgency situations. As a trickle charger will prevent the car battery from draining energy even if the car battery is rarely used.

To do trickle charging method, we need to use a trickle charger. A trickle charge for car is defined as an electrical charger which works at a very slow and steady rate. Because of its distinct low amperage, the trickle charger will little by little charge the car battery as the battery depletes energy. Also, some variants of the trickle charger are designed to be left linked to the car battery for long periods of time (like winter), reduce the risk of battery damage or battery explosion to minimum level.

Different Types of Trickle Charger

When talking about trick charger, we often think that we only have one type which is Smart style. But actually, you should know that we have 2 two types of trickle charger which are:

1. Dumb

This is a traditional type of battery charger that basically have lots of cables plugging into a wall socket. We can easily buy a dumb trickle charger at a very cheap price. Cheap but not mean low quality. Dumb trickle chargers are quite powerful, which can always be able to charge any battery of any size.

2. Smart

Smart style is a high-technology design that is the reason why smart style is more expensive than traditional design, dumb style. Nowadays, thanks to the rapid development of technology, the price for smart trickle charger is falling sharply. This design has the ability to automatically switch on and off, based on the battery level. That makes them much safer than Dumb style, specially for long-term use.

On the list of top 10 best trickle chargers to purchase mentioned below, we only focus on “Smart style” chargers, thus we just don’t see that much benefit to a dumb style charger frankly. Using a traditional charger will bring to you a little danger because they lack monitoring ability which can lead to a serious overheating battery if you do not monitor it carefully.

Trickle Chargers Vs. Normal Car Battery Chargers

The main purpose of using a trickle charger is to charge a battery slowly and prevent it from overcharging – though, we can achieve the same result through using a standard charger. If you regularly store batteries for a period of time, a trickle charger is a good investment for you.

But in the situation that the first priority of your charging activities require a fast charge for speedy demand and you occasionally need to store your battery, auto experts recommend you should invest in a normal charger and just plan on charging the stored battery every 30 – 40 days.

Thus, just make sure that before putting your battery away, it should be fully charged and then you can be able to maintain its charge without any problem.

    The picture above of the Schumacher Trickle Charger is the exact one I purchased. The included instructions & yours doesn’t tell me what the cable with the two circles are used for. Considering they have a red & black wire (negative/positive) what are they for? Don’t use my car very much and it has something draining my battery, which no one has been able to find, so just leaving it over the weekend, come Monday I need a jump start. I waste more gas just sitting in my car running it for 20 minutes just to charge my battery. Purchased thus charger over two weeks ago and still don’t feel comfortable to connect it. Not mechanical at all. H-E-L-P
