This Year’s Buying Guide
If you’re looking for one of the best battery chargers for motorcycles but don’t know much about these types of devices or which of the numerous models to go for, then you’re in the right place. Here are a few things you might want to know about battery chargers and their most important features so that you can choose the most suitable model to keep all your batteries at full charge.
Smart charger vs the best battery trickle charger
While trickle chargers can provide you with an inexpensive way to charge your dead batteries, they aren’t the best choice nowadays, especially with so many smart chargers around. A trickle charger will apply current to your battery at all times, even if the battery is full.
That makes it a good choice if you can supervise the charging process and want to save a few bucks on the device. However, if you plan on leaving your motorcycle in the garage during the winter months, then a smart charger is what you need. This device is fully automatic so you don’t have to keep an eye on it or disconnect the battery when at full charge.
If a trickle charger may overcharge your battery and cause damage, a smart charger will only apply current until the battery is full, and then only start charging when the voltage has dropped below a specific level that you may or may not be able to set manually.
While more expensive, a smart charger or maintainer will allow you to keep your battery connected indefinitely so that you don’t risk having the battery or motorcycle electronic systems become affected by a long period of inactivity.
Choose a versatile model
Whether you’re looking for a battery charger for BMW motorcycle or a universal charger to work on your bike as well as on the car, tractor, or boat, then you surely want to go for a versatile model. The good news is that there are quite a few models that come with multiple modules which not only work on a variety of vehicles, but they also come with multiple charging modes.
You can get a microprocessor-controlled device that can feature 3 or 4 charging stages such as initialization, bulk charging, monitoring, and float mode. A good motorcycle battery charger will also come with a desulfation mode which it achieves through pulse charging at high frequency. A charger with a desulfation mode can effectively revive a dead acid-lead battery.
A battery that’s been left unused for extended periods of time can suffer from a buildup of lead sulfate on the plates, which in turn results in the battery being unable to hold much charge. Through a desulfation process, the crystals are broken down, leaving the lead plates clean and helping restore functionality and battery capacity.
Get a resistant charger
Especially if you’re planning to go on a very long trip during which the motorcycle might not be used all the time, getting a rugged battery charger might be the best thing to do. You want a model that has a strong plastic case that’s waterproof and dustproof so you don’t risk having it damaged down the road.
You might also want a charger that can operate at extreme temperatures. You can easily find chargers that can work at temperatures from 0°F to 130°F without overcharging or undercharging.
Maintain battery health with a solar charger
If your motorcycle often gets left unused and you keep it parked outside on your property, then you might want to consider getting a solar battery charger for motorcycles. Such a device will trickle charge your battery and maintain it at healthy levels throughout the winter or when you’re not taking the bike for a ride.
These solar chargers are an ideal choice if you’re leaving your motorcycle in areas where there’s no electricity. You also get weatherproof connectors as well as extreme temperatures functionality out of a quality solar charger. However, you shouldn’t expect the charging process to be fast, especially when the charge current is usually between 10 and 100 mA.
Other features to consider
When looking at chargers for sale, you might also want to ensure that the model you’re getting comes with more than one way to recharge your battery. You want the charger to have the standard clamps for easy and fast charging, but also some O-ring connectors that are great when you’re planning to leave the battery connected to the charger for long periods of time.
If you think you’re going to use the charger on a car as well, then it wouldn’t be a bad idea to look for a device that also features one or more DC plugs for extra convenience so that you don’t have to get your hands dirty to charge the battery.
Protection is very important when charging a battery, and that’s why you should pick a charger that comes with spark-proof connectors, as well as reverse-polarity and short-circuit protection. You might also want to look at charging rates so you can decide whether you want a slow maintainer or a fast charger.
Get more info on the charging progress
Another extremely helpful feature is a LED indicator display. With older models, you never knew if the battery was actually charging, when it was fully charged, or whether there was a problem in the system. Thankfully, many modern chargers come with LED displays which can be simple or more complex.
A simple indicator will show you when the battery is charging and when it’s at full capacity. More sophisticated chargers will show you a lot more info regarding the charging progress, charging level and stage, as well as diagnostics for potential problems. With such a device, you can also check to see if the battery is just low on power or nearing the end of its life cycle.

Can you charge a dead motorcycle battery?
No matter what type of battery you have on your bike, whether it’s a Lithium one or another type, you do need to check it from time to time, to make sure that it still has power. However, if the bike is not used too often and spends a lot of time in a garage, the battery might become completely drained and most riders don’t pay attention to this detail until it’s too late.
The result is that they check out the reviews to figure out what is a good brand to go and purchase a new one. As you can imagine, this means spending more money when it shouldn’t really be necessary. The good news is that if you pay attention to small details and look at every sign the bike might give showing that it doesn’t have enough power, you can prevent this from happening.
It’s also possible to save the battery, if you take some of the measures detailed below. Besides the vehicles that are parked for too long, sulfation can be another reason that can lead to a dead battery. This aspect applies mostly to lead-acid batteries, so if your bike is using another type, such as a Lithium one, then this is not such an issue.
Sulfation means that sulfur adheres to the lead plates located inside the battery, which in turn blocks the flow of current and reduces the unit’s power. If you are tempted to go through reviews and see what other models are featured, you should first try to revive the one you already have – older batteries have rights, too!
How to fix the battery
If you are not using tenders to keep your battery in top shape and it loses power, then you should do a thorough check-up first. Make sure that you use all the necessary protective equipment, such as goggles and gloves, because what these power units contain are extremely toxic substances.
This goes for every type of battery, but especially for those that use sulphuric acid. Carefully remove the battery and keep it at room temperature before starting to work on it. The cell caps need to be removed first and the battery fluid completely drained. By this point, you are probably thinking about using one of those effective battery tenders in the future.
When the unit is completely empty, you can prepare a solution that combines distilled water and magnesium sulfate in the right amounts and then fill every single battery cell with it. The entire unit needs to be shaken to adjust the solution level and there are no rights and wrongs here, so simply get it evenly distributed among the cells.
Then the battery needs to be charged with a slow-charging option to prevent having too much power go through it, as this might cause damage. You need to connect the clips, each one on the right post, and leave the cap off while it’s charging. Then you can remove these, replace the cell caps, and then reinstall the battery.
Frequently asked questions about motorcycle battery chargers
Q: Can I use a motorcycle battery charger on a car?
You can use a motorcycle battery on a car, but you’ll probably need at least 12 volts to start a car battery. A motorcycle battery charge is meant to charge at much lower rates in order to avoid causing damage to the cells or other parts of the battery. What this means is that you’ll have to be really patient if you want to fully charge your car battery.
This is valid for special motorcycle chargers. For multi-purpose units that work both with 6V and 12V batteries, you can actually charge the batteries of a wide range of vehicles.
Q: How to test a motorcycle battery charger?
Whether you suspect that something is wrong with your motorcycle battery charger or you just want to test a new model, you can do so with the help of a voltmeter. The first thing you need to do is to take a voltmeter, adjust it to DC volts and set it to the 20-volt range.
Now place the voltmeter leads to the terminals of the battery while making sure you don’t mix positives with negatives. You should then start the engine of your motorcycle and accelerate until you hit around 3,000 RPM. Check the voltage reading with your manual to see if the values are normal and decide whether the charger works well or not. Next you need to know how to charge motorcycle battery – it’s recommended that you do your research beforehand.
Q: How does a motorcycle battery charger work?
Getting all the technical details right would probably require you to read a small book on the actual mechanisms and charging process. What you need to know is that a motorcycle battery charger, or any charger for that matter, works by applying a constant DC or pulsed DC power to the battery.
Trickle chargers have slow charging rates because they force only a small amount of current through the battery. You can also get fast chargers that can charge 2 Amps or even more per hour and get a low battery up to full charge in just a few hours.
Q: Can you leave a motorcycle battery charger on overnight?
You can definitely leave your battery connected to a charger overnight with most modern models. While older trickle chargers posed a threat to the integrity and safety of the battery, current models actually feature multiple charging modes that prevent such damage.
A standard charger will come with at least one normal charging mode and a float mode, the latter which will only keep the battery fully charged without overcharging it. With some models, you can leave your battery connected for extended periods of time and ensure you have a full battery ready to go anytime you need it.
Q: What’s the best motorcycle battery charger?
There’s no way to point to a specific make and model of battery charge and claim that it is the very best. Each charger comes with its own specifications, features, pros, and cons. Prices also range widely from one model to another, influencing what one might call the best charger.
What is important is that you look at your own motorcycle battery and then check the specs of some of the most popular models available online. Doing so will enable you to select a charger that comes with all the features you want and none of the ones you don’t need.
