Motorcycle Battery Is Draining While You’re Riding, why?, Since the invention of motorbikes, they have had some type of battery. Batteries have improved in their ability to power motorcycles throughout time, but that doesn’t imply they’re perfect.
Battery problems are really aggravating. It’s much more aggravating when you’re out for a ride and find you’re losing power or the battery is entirely depleted by the time you come home.
When riding a motorcycle, why does the battery drain? A faulty battery terminal connection, corroded battery terminals, a bad stator, a bad rectifier/regulator, too many electrical add-ons, and if you have a newer motorcycle, an automated shut-off will happen if the battery cable rattles loose are all reasons why a motorcycle battery drains while riding.
Having dealt with every type of battery problem imaginable over the previous few years on the dozen or so motorcycles I’ve owned, I’ve gained a basic understanding of how motorcycle batteries function and why they might drain while riding. This essay will explain why this occurs, as well as provide other useful information if you find yourself in a similar scenario.
Battery Drains While Riding for a Variety of Reasons
When your motorcycle struggles to stay running when you’re out on a ride, it’s never a good sign. There could be a variety of reasons for something like this, but the battery is most likely to blame.
The battery’s purpose is straightforward, yet it is dependent on other components to perform properly. A poor terminal connection could be the first cause of a motorcycle battery draining while riding. A battery’s terminals are the two little metal rods that protrude from the top on either side.
When a motorcycle’s terminal connection is bad, it means the battery wire is either faulty or not attached at all. While the stator is operating, the battery should be charging, but if there is a poor connection, your battery won’t get much of a charge.
Corroded terminals, on the other hand, might cause a battery to deplete while riding. It’s possible that battery acid will form on these terminals, forming a barrier between them and the cable that connects to the stator. Because of the inadequate connection, the battery will receive little, if any, charge when riding.
If the connections appear to be connected, a faulty stator is the next (and most likely) cause of your motorcycle battery draining while riding. On a motorcycle, the stator is essentially an alternator in a simpler form.
The stator’s job is to keep the battery charged while the motorcycle is running. When a stator fails, the motorcycle is forced to run solely on battery power, which quickly depletes the battery. Batteries were not designed to power the bike while it was running, but rather to start it. To learn more about how a motorcycle stator works, see my other article here.
A motorcycle’s regulator/rectifier is part of the alternator system, but it’s normally separate from the stator. Because batteries can’t store AC current, the regulator/rectifier turns electricity into a current that the battery can handle. If the regulator/rectifier fails, the motorbike battery will drain while riding.
When the regulator/rectifier fails to do its job, it may not convert the power into a voltage that the motorcycle can store, resulting in the battery receiving no power at all.
A motorcycle battery can also be drained by aftermarket modifications or additional electrical add-ons. LED lights, phone chargers, and other accessories are examples of such add-ons. When these types of add-ons are installed on a motorcycle, it’s likely that the wiring was done incorrectly.
When these are utilized while riding, they draw extra power from the battery, especially if the grounding is inadequate. Because these are sucking so much power from the battery, it will drain throughout a ride and may not be able to start the motorcycle the next time you try.
A faulty battery could also be the cause of a battery depleting while riding. If the battery is old or expired, this is more likely to happen. A standard motorbike battery should survive for at least four years, or 48 months. However, it is not rare for people to give up before then. Check your battery’s expiration date; if it’s approaching, it’s probably time to replace it.
The last reason a motorbike battery drains while riding is more common in newer motorcycles. If a battery wire on a newer motorbike vibrates free, it may cause the machine to shut off. This is a safety feature designed to keep the cable from touching the earth and producing a spark. The motorcycle will normally shut down abruptly as a result of this.
The Function of the Battery
On a motorcycle, the battery’s primary function is to start the vehicle. Unless you have any other electrical add-ons, that’s pretty much all the battery can do. When the motorcycle is turned on, the stator takes over and helps the bike run while also recharging the voltage that the battery used to start it.
You might not notice that your motorcycle battery is emptying until you go to start it up again for the following ride. However, as previously said, additional underlying issues will present themselves by the battery draining substantially while riding the motorcycle.
The battery’s function is straightforward, but if it fails, the complete motorcycle may not be able to run. Knowing how the battery works and what’s connected to it can help you as a rider figure out where to look if you’re having problems.
How to Tell if the Problem Is With The Battery
When your motorcycle is acting up, most motorcycle riders come to a few conclusions. And it’s usually the battery that’s at blame. There are a few signs to check for to see if you’re really suffering with a battery draining problem when riding your motorcycle.
The first and most evident indication is that your motorcycle loses power and becomes increasingly slow over time. It’s possible that the motorcycle will perish at some point. In this circumstance, you’ll also notice that any lights turn dim.
When you try to start the bike again, you’ll hear clicking noises, which indicate that the battery is draining. This clicking sound is caused by the motorcycle attempting but failing to take electricity from the battery.
The last and most obvious way to know if your motorcycle battery is still draining while riding is if you can jump start or charge it and it starts right up. This doesn’t always mean the problem is with the battery, so go over the checklist again to figure out what the underlying issue is.
What Should You Do If Your Battery Runs Out While You’re Riding?
One of the most inconvenient things a motorcycle can do to us is leave us stranded because the battery has died. I’ve been there a few times and had to get inventive in order to get home.
There are a few things you can do if your battery dies while you’re out riding, especially if you’re far from home. First, double-check all of the connections to the battery for tightness.
You can also get a jump start from another motorcycle or from a car. If you get a jump start from a car, you should proceed with caution because the motorcycle battery may be damaged. Connect the positive (red) cable to the motorcycle battery’s positive terminal and the negative (black) cable to the bike’s metal frame. The positive cable should be connected to the positive terminal of the car battery, and the negative cable should be connected to the negative terminal.
Do not start the vehicle. Because the battery is powerful enough to transmit adequate voltage to the motorcycle, you can try to start it without starting the automobile.
