What to Consider in Buying a Motorcycle Battery Charger
You can choose between regular, trickle, and float chargers. Regular chargers work pretty much the same as phone chargers. Once you plug it in, it’s charging until you unplug it.
A trickle charger is quite common since it uses somewhat more advanced technology. It monitors the charge level, adapting to the needs of the particular battery.
A floating charger charges the battery fully before shutting off. It turns back one once the battery drains a bit.
Durability depends on many different things. It’s especially crucial if you’re looking for a charger to carry around to trips.
It should have a strong plastic case that’s also dustproof and waterproof. You want it to endure the ride along with some rough use and maybe an occasional drop to the ground.
Think about if you need it to work at extreme temperatures. Some can operate at temperatures from 0°F to 130°F without undercharging or overcharging.
Look for a versatile model if you think you’ll charge more than just your motorcycle. In most cases, these chargers can work with motorcycles, cars, boats, tractors, and other similar vehicles.
Plenty of models come with several modes and the ability to charge all kinds of vehicles. Look for a microprocessor-controlled device with several charging modes like initializing, bulk charging, monitoring, and float mode.
Also, keep in mind that not every charger can recover a battery that’s been left unused for a long time.
Look for a charger that comes with at least two charging methods. It should feature standard clamps along with O-ring connectors. The two give you an option to choose, depending on your needs and preferences at the time.
If you think you’ll use it on a car as well, you should make sure it comes with DC plugs for some added convenience.
It should have as many handy features as possible so that the entire process is easy and quick regardless of the vehicle you’re charging.
Safety is always critical, especially when charging batteries. For this reason, low-quality chargers may not be the best choice because they often lack some of the most critical safety features.
Look for a model that’s spark-proof and has protection against short-circuit and reverse-polarity. On top of that, you should also consider if the model of your choice has safety certifications. These prove that the charger is safe to use when used according to the instructions.
It’s always important to check how compatible the charger is with your battery. As you noticed, these come with different terminals, which is why it’s critical to consider how they clip on.
You should check how long all the wires and cables are because they are often quite short. This can make it a bit tricky to use, especially if you’re away from home.
Some come with standard clamps while others come with O-rings. However, many models offer both options.
LED Indicator Displays
Having a LED indicator display makes all the difference when it comes to ease of use. Without an indicator, you have no way of knowing if it’s charging and how long it will take for the process to complete.
LED indicators are typically quite simple, although some models can be a bit tricky to figure out. It shows when it’s charging and when it’s fully charged.
Many show diagnostics for different problems, making it easy to figure out what’s wrong.
Most models can work with all motorcycles, cars, and even some larger vehicles such as trucks and boats. However, it’s always recommended to check if the particular model you’re interested in is compatible with your battery.
This is easy to figure out as most manufacturers list compatibility information. All you have to know is details about your battery in order to find the most compatible charger.
Voltage and Wattage
One of the most important things to consider is the voltage. The volts of the charger has to match the volts of your battery for everything to work correctly. For example, you should charge a 12V battery with a 12V charger only.
Also, check the amps as they show the power that the charger supplies to your battery. Lower power is ideal for the long term, but you should still look for a model that delivers fast charging when needed.
One of the best things to look for is a temperature monitor. Temperature is critical, which is why you should always have a precise idea of its level.
High temperatures can cause damage to both the charger and the battery. For this reason, look for a model with protection features since those are unlikely to cause overcharging. It’s vital because overcharging often triggers overheating.
As you noticed, most models feature several charging modes. While there are plenty of models that do no more than charging, some of the most advanced chargers can do much more.
Look for the one that has a trickle charge setting. It reduces the overall power that’s delivered to your battery once it’s fully charged.
Another great mode is the maintain-charge setting. It allows the charger to shut off, maintaining the level by occasionally charging.
Most models have four modes, including Initialization, Bulk Charge, Absorption Mode, and Float Mode.
Battery Charger Vs. Battery Maintainer
People often mix chargers with maintainers because the market does little to explain the difference. What you should remember is that chargers, for the most part, send constant charging even when the battery is full.
This can often cause overcharging unless the model of your choice is protected against it.
A maintainer senses how much charging your battery requires, sending a trickle charge for a few hours. It then stops charging once the battery is full.
The difference is minimal, but in most cases, a maintainer can’t cause an overcharge.
Breaking Down The Types
A float charger is essentially the same as a maintainer. It charges your battery before shutting off. This allows the battery to drain a bit, which is when the maintainer turns back on to charge it a bit.
It doesn’t work all the time, which reduces the chances of overcharging and overheating.
A trickle charger was initially made to replace standard models. It’s among the most commonly used types at this point.
It features advanced technology that monitors the charge level, adapting its cycle to your battery’s requirements. Also, this type doesn’t waste any power, and your battery will always be charged regardless of when you unplug it.
As we said, these work pretty much the same as phone chargers. It works continuously while it’s plugged.
Although this doesn’t sound as bad, leaving the battery connected for too long can damage it and possibly even cause a fire. Plus, you’d be wasting too much power.
Keeps Battery Healthy
Leaving your bike unattended for months isn’t the best thing you can do for its battery. You may find it dead and unable to recover, which is why you should consider keeping it on a charger.
However, keep in mind that constant charging can also damage the battery unless you have the right charger that can prevent this.
Money and Energy Saving
The best charger will reduce the power supplied to the battery. What this does is it protects the battery while also saving energy.
Having a suitable charger will keep the battery charged without wasting any energy or money.
Overcharging is a dangerous thing, and once it happens, your battery is as good as trash. This is only one of the reasons why you should use a charger and maintainer. It saves you from having to replace the battery as often.
Leaving your charger plugged for a more extended period may cause a fire. It’s extremely dangerous, which is why you should use a maintainer. These are much safer to keep plugged for an extended period, monitoring the entire process while decreasing power output.
Why You Should Buy a Good Battery Charger for Your Motorcycle
Having a good charger ensures a constant charge. It recharges and maintains the charge during the time you’re not using the bike.
It’s a steady stream of electricity, keeping the energy potential positive so that your battery is always ready when you need it.
Also, keeping your battery charged prevents the degradation of its components. It helps to prolong the overall life of the battery as well, which means you won’t have to replace it any time soon.
