Our Comprehensive Buying Guide
As you are looking for the best battery tender for motorcycle, some of you may wonder whether such a unit is indeed necessary or not. However, the answer is that everyone who has a motorcycle should own a battery tender as well, as these useful units work great in prolonging that battery’s lifespan so that you can enjoy a ride whenever you want to.
Ensuring that the battery is kept in top shape means that you will benefit from the best performance every time you take the bike out. On the other hand, it’s also true that you want to get a high-quality battery in the first place, but this is another story. If your vehicle and its battery are high-quality and well-maintained, then a good battery tender is surely going to help as well for optimal performance.
Plus, you won’t have to worry about ensuring the battery’s maintenance more than it’s necessary. With this being said, there are a few things that you want to keep in mind as you are browsing through the options in order to pick the right unit.
Safety First & Other Features
We know that this is something we often hear around us, but this doesn’t mean that it’s any less important than we think. Safety should always come first, no matter what activity and products or devices we are using. The same goes for battery tenders, so you want to look for those devices that come with special features in this direction.
For instance, one aspect that the battery tender should include is a spark-proof feature that ensures the unit doesn’t deliver any power unless it’s properly plugged in and connected to the battery. This means that there’s no risk on the user’s part and also that the battery itself is protected over time.
Next, you want to look for overcharge protection included in the unit’s construction as well, given that this is very important for the battery’s lifespan. If the device is overcharged, especially often, this can really damage it, which means that you will incur more costs than necessary by purchasing new batteries very often. Therefore, you should actively avoid any such situation.
On the other hand, the good news is that many models come with this feature, so finding the right alternative should not be a problem. Even more, there are some that include smart systems that constantly receive feedback from the battery and automatically adjust the charging level based on what’s necessary. Of course, such units are ideal and a very good long-term investment.
Some Other Aspects to Keep in Mind
If you live in an area with extreme temperatures, this can really put a strain on your vehicle’s battery. Also, you shouldn’t think that just because you don’t use your motorcycle every day, the battery won’t become obsolete over time.
The truth is that these units do need maintenance, and they have a limited lifespan that can be easily prolonged if you decide to make a small investment in a reliable battery tender. Therefore, especially if you live in an area with low temperatures during the winter season, it’s a very good idea to consider getting one of these as part of your bike’s gear.
Along the same lines of convenience, it’s important to think about how much space you have available when you choose the battery tender you are going to use. There are some who have very large garages, so space is not an issue, but if you keep your bike in a smaller protected room around your backyard, you may want to think about how easy the unit is going to be in terms of handling it.
In these cases, portable and compact battery tenders are definitely the way to go. They are handy and easy to use, so they won’t become burdensome, and many of the models you can find available for sale are also highly reliable, so they can get the job done without any trouble.
A Trickle Charger or a Battery Tender?
The main difference between a battery tender and a trickle charger is that the former turns on and charges the battery only when the discharge level goes below a certain point, while the latter constantly charges the unit. While these two types of devices might seem to be pretty much the same thing, there are significant differences in terms of results.
The battery tender works great if your bike’s battery is not used very often, given that it doesn’t degrade its lifespan in any way. The trickle charger can induce some damage over time, given that it constantly delivers power to the battery.
Frequently Asked Questions
Q: What is a motorcycle battery tender?
A battery tender is a very useful device specially created to prolong a battery’s life by keeping it optimally charged at any given point. While traditional battery chargers constantly deliver the same level of power to the battery, tenders come with different and upgraded features.
What makes them such a good choice is the fact that their technology allows batteries to deliver feedback and the level of delivered power is adapted in real-time in order to keep everything optimally balanced and avoid any overcharging. This means that the battery’s lifespan is sustained and prolonged, making battery tenders a very good investment.
Such units are most useful when you have a motorcycle that you don’t use every day and that may be parked in the garage sometimes for months. As you can imagine, using a battery tender during the winter season can be very helpful as well, as when the spring comes, you can take the bike out for a ride without any trouble.
Q: How long does it take to charge a motorcycle battery with a battery tender?
The answer, in this case, depends on various factors, including whether the battery is completely drained and the type of battery tender you have. On average, it takes a minimum of 4 to 5 hours to charge a battery using a tender, but there are cases in which it can take a lot longer.
For instance, if you have a 2-amp battery tender and the battery is completely drained, it can last more than 24 hours to get the unit back to a full charge. It’s also very important to keep an eye on the entire process by checking on the battery from time to time during this time.
The good part is that most battery tenders come with convenient LED indicators that let you know the status of the charging session, so figuring out if it’s going to take a lot longer should not be an issue.
Q: How do you hook up a battery tender to a motorcycle?
While this process is not a complicated one, you do want to take some precautions before you get started. The first thing you want to do is make sure that you have access to both water and soap, in case any battery acid accidentally comes in contact with your skin. You should also wear protective clothing and work in a ventilated area to prevent anything bad from going on.
The charger should be located far away from the battery, usually as far as the cables allow. Next, you want to make sure that everything is turned off, and that the AC plug is not connected to any power outlet.
You will have to locate both the positive and the negative battery posts and see which one is grounded. Next, you will need to connect the charger’s clips on the battery’s connections.
