Battery Charger vs Battery Tender vs Battery Maintainer

Best Motorcycle Battery ChargerKeeping motorcycle batteries charged is quite a concern for most motorcyclists, irrespective of whether you are traveling for a long distance or a short distance. It might not be such a significant concern for motorcycles that are used daily.

However, for those that are not used daily, owners need to get the right battery chargers to keep the batteries charged and prevent damage.

Battery Charger vs Battery Maintainer

The two most popular devices that come in handy for this purpose are battery chargers and battery maintainers. The main difference between these two is the level of complexity that they come with. The battery maintainers, for instance, contain more advanced circuitry than most battery chargers. The circuitry is the part of the device that’s used to detect the charge level of the batter. It serves the purpose of determining the need for the battery to charge, as well as how fast it needs to charge.

Most battery chargers are designed to charge at a constant rate. However, the rate is often below the battery rating and can take up to 10 hours or more to charge. This helps to reduce the potentiality of overcharging the battery. This is perhaps the primary reason why some batteries get charged overnight. The battery maintainer comes with circuitry that is able to charge the battery at a faster rate while regulating the current to prevent overcharging. With this in place, charging time can be shortened by a few hours.

Battery Tender

Battery tenders, on the other hand, are specially designed devices that can help to keep the battery charged for a long time. Unlike the others, this device helps maintain the charge level of batteries for a while. It is especially necessary for motorcyclists that would need to leave their motorcycles inactive for two weeks or longer. The tender will help to ensure that the battery maintains its charge level at proper storage voltage when it is not in use.

How Does a Motorcycle Battery Charger Work?

Motorcycle Battery Charger ReviewAlthough it might seem complicated at first look, the working system of most battery charger is often simple to understand on a closer look. You will find the working system of most battery chargers from the manufacturer’s manual usually included in the pack.

On a generic note, however, a battery charger includes several vital parts that help it to perform optimally.

Getting all the technical details correctly would probably require that you read a small book on the charging process and the actual mechanism of the charger. What you need to know is that a battery charger works via the application of a constant DC or pulsed DC power to the battery.

Different chargers have different working processes. Trickle chargers are designed to feature slow charging rates because of their ability to force only a small amount of current through the battery during the charging process. Other fast chargers can charge up to as fast as 2 Amps or even more per hour, ensuring that you get a full charge in just a few hours.

Types Of Motorcycle Battery Chargers

Types Of Motorcycle Battery ChargersLike motorcycle alarms and every other motorcycle accessories that you can think of, there are different types of motorcycle battery chargers, and each type has its working process. Here, take a look at some of the most popular types of motorcycle battery chargers that can be found in the market.

1. Regular Chargers

Regular motorcycle battery chargers work in the same way with phone chargers. All you need to do is to just plug your battery in, on it, and it would continue to charge at the same rate until you decide to unplug it. While this can be classified as the simplest way of charging motorcycle batteries, the problem with it is that you would need to be around to unplug it when charging is complete. Leaving the battery plugged in to this type of charger for prolonged periods can potentially damage the battery, cause power wastage, and fire hazards in some extreme conditions.

2. Trickle Charger

This is another relatively popular type of charger. It is designed to replace the standard style and has gained massive acceptance across boards today. These chargers are designed to use advanced technology for monitoring the charge level, as well as for adapting to the unique needs of your battery. It is often referred to as the “plug and forget” style, and its most significant benefit is that it reduces the unnecessary power waster that most traditional chargers are known for. Its only advantage over a float charger is that irrespective of the time you plug it, the battery will still be fully charged.

3. Floating Charger

A floating charger is otherwise referred to as a battery maintainer. It still improves on the traditional motorcycle battery charger, although it uses a different technology than trickle chargers in this case. A float charger is designed to shut off after charging the battery fully. It then allows the battery to drain to a certain level, before coming back on to repeat the same cycling. It helps to save more power and to eliminate fire risks. The only disadvantage of this is that depending on the time of disconnection, your battery may not be fully charged.
