Motorcycle Battery Guide: How to Choose, Maintain and Replace Your Battery
Most motorcycle riders do not think about their motorcycle battery unless they're trying to start it in the morning and it won't start. How often do we hear about the best motorcycle batteries?
If you were to ask the local enthusiasts what oil, chain lube, or pipe wrap is best, you would surely get multiple answers. However, when it comes to batteries most don't know where to begin. The battery is something most riders rarely think about until it fails.
Did the light not come on fully, did the start switch simply click, or are we greeted with that wonderful sound of the starter motor? In the end, a rider's life will surely be busier when it comes to the battery. The rider must not overlook the motorcycle battery, as it is a key part of the motorcycle's electrical system. It helps start the engine, powers the display and supports systems such as fuel injection. As we enter the modern-day motorcycle era, electrical components are growing and adding to the electrical demands of the motorcycle. High-performance motorcycles can also put more demands on the battery.
With the right battery, many headaches can be avoided. Here is a rider-to-rider guide to motorcycle batteries:
Why Bother With the Motorcycle Battery
Modern-day motorcycles are bringing a new level of performance that most manufacturers have been striving for. Adding features to motorcycles is allowing manufacturers to meet the performance appetites of the masses. From ABS and fuel injection to TFT displays, alarms, GPS, heated grips and more, all are making their way onto motorcycles.
A faulty battery would once have been a pain, but modern-day battery failure can cause a number of inconsistencies in the motorcycle. Displays not working correctly, warning lights and starting issues can all be signs of a weak battery. However, not every electrical problem is caused by the battery. The charging system, wiring or accessories could also be responsible. A rider who spends a lot of time on the road and not in the garage should know the signs of a faulty battery.
This way the rider is not spending time at the petropump trying to jump his motorcycle after not riding for a weekend. In the next section, we'll discuss the different types of motorcycle batteries.

Main Battery Types
As a rider, you will probably be choosing a battery based on what fits in the battery compartment your motorcycle manufacturer put there. Most riders will not bother with anything other than the size. There are only a handful of different battery types, and in most cases, you will see conventional, AGM and lithium.
Conventional (Flooded)
These are the standard batteries most riders would have seen on older motorcycles. Some serviceable flooded batteries need the electrolyte level to be checked periodically and topped up if needed. Distilled water should be added only if recommended by the battery manufacturer. These batteries tend to require more attention, as they are also sensitive to their positioning.
These batteries are more commonly found on older motorcycles and certain current motorcycle and powersports applications. The batteries may be cheap, but they require more of the rider's time, which most will not give.
AGM (Absorbent Glass Mat)
These are among the most common types of batteries found on modern-day motorcycles. The batteries require very little maintenance and provide a good power source with minimal effort on the rider's part. Clean and secure battery terminals are still important to keep them in working order.
These are a common choice for the average rider who does not want to put much effort into motorcycle battery maintenance.
Lithium
Lithium batteries provide strong performance with minimal weight. Track-day bikes and performance-oriented riders may appreciate the benefit of a lighter battery.
However, performance-oriented motorcycles do not automatically require a lithium battery. The battery must suit the motorcycle's electrical and charging system.
The prices of these batteries are usually higher, and a rider should make sure that the motorcycle's electrical and charging system is suited for a lithium battery and that he has a lithium-compatible charger or maintainer when required. Sometimes the benefits of a lightweight battery are not worth it to the average rider.
For a closer look at the differences, riders can also read our guide on AGM vs Lithium Motorcycle Batteries.
How Long Does a Motorcycle Battery Last?
The average motorcycle battery can last around 2–5 years, depending on the battery type and how it is used. Some batteries will outlast this time frame, while others may fail well before it.
Regular riding can help keep the battery charged, provided the motorcycle is ridden long enough for the charging system to replenish the energy used during starting. Very short rides may not give the charging system enough time to replace the power used during starting.
Modern-day motorcycles have plenty of features that may continue to draw a small amount of power even when not in use. Battery life is also affected by the type of battery on the motorcycle, maintenance, storage and riding conditions.
The next section will discuss the warning signs that may indicate the battery is faulty.
Warning Signs of a Failing Battery
A battery can sometimes fail suddenly, but there are often warning signs such as slow starting, dim displays or repeated loss of charge. Having slow starts, dim displays and the need to charge or boost the battery more often are all signs that the battery is struggling to keep up.
Failure to start is also a major warning sign. These are only a few signs but the rider should understand that when the start switch is barely doing anything and the display on his motorcycle is flickering, it is usually time to have the battery tested.
A battery that repeatedly loses charge or has been deeply discharged may have suffered permanent damage.
When Should You Change the Battery?
Most riders have had the displeasure of having to boost or jump their motorcycle due to a weak battery at some point. If the battery is 3 or more years old and starting has become more difficult, it is usually a good time to have the battery tested and consider replacing it.
The rider should also change the battery if the battery shows signs of damage, swelling, leakage or poor terminal condition. A rider should never be on a questionable battery when he is on the verge of a long road trip. It is better to change the battery than to find yourself miles away from home due to a faulty battery. The importance of choosing the right battery is discussed in the next section.
Choosing the Correct Battery
It is very important to choose the correct battery. This means choosing the correct size that will fit the motorcycle. The battery code, voltage, amp-hour rating, CCA, physical size, terminal position and other specifications should match your motorcycle's requirements. Most motorcycles use 12-volt batteries, but it is very important to ensure that this is the case for your motorcycle.
The easiest option is to check the battery specified in the motorcycle owner's manual or match the existing battery's part number. If there is any doubt, check the manufacturer's specifications before ordering.
A higher amp-hour rating is not automatically better. The easiest option is to stick to the battery recommended by the manufacturer of the motorcycle. The next best option is to use a replacement battery that matches the recommended specifications. Riders should never save money on a battery that they are unfamiliar with.
It is much more cost-effective to spend the extra cash at the counter than deal with the frustration of a poor-performing battery.

Additional Demands From Modern Motorcycles
Modern-day motorcycles have more features now than ever before. These additional features can increase electrical demand, which can cause headaches for the rider if the battery is not performing. This could range from a faulty GPS display to a complete inability to start the motorcycle.
When the rider assumes that an expensive part has failed, the battery is one of the things that should be checked first. However, not every electrical issue is caused by the battery. The charging system, wiring or accessories could also be responsible.
A good battery that is compatible with the motorcycle should be used for modern-day motorcycles. Avoiding batteries that have an unknown storage history or have been poorly stored is also a good idea. In the next section, we'll discuss some simple tips for extending battery life.
Tips on Prolonging the Life of the Battery
Keeping the terminals clean and secure is one important way to help prolong the life of the battery. The battery should also be kept properly charged. A battery maintainer should be used if the motorcycle will be in storage for a period of time. The maintainer should be compatible with the type of battery being used.
This is especially true for motorcycles with alarms, GPS, and other accessories installed on them. The rider should also be wary of accessories installed on the motorcycle, as poor wiring can cause more issues than solutions. If the new battery is dying quickly, the motorcycle wiring or charging system could be to blame. The importance of short rides is discussed in the following section.
Short Rides and the Battery
Short rides and frequent starts can be hard on the battery. Starting the motorcycle uses power, and the charging system needs time to replenish the battery. If the rider has lots of short rides and is stuck in traffic often, this should be considered.
This is especially important if the motorcycle also has several electrical accessories. A motorcycle that is only used for short trips may not give the charging system enough time to fully replace the energy used during starting.
The following section will discuss the effect long periods of storage have on the battery.
Long Periods of Storage and the Battery
Long periods of storage can slowly discharge the battery, especially if the motorcycle has an alarm, tracker or other electrical system that continues to draw a small amount of power. Natural self-discharge can also reduce the battery's state of charge over time.
When the motorcycle is eventually taken out for a ride, it may not start due to a weak battery.
A suitable battery maintainer can help avoid this situation. It is much more cost-effective to use a suitable battery maintainer than to replace a battery unnecessarily every year.
The maintainer should always be suitable for the type of battery being used, and the battery and charger manufacturer's instructions should be followed.
The effect of both hot and cold weather on the battery is further discussed in the following section.
Weather and the Battery
Hot weather can slowly reduce battery life. High temperatures can speed up the chemical reactions inside lead-acid batteries and contribute to a shorter battery life over time.
Cold weather creates a different problem. Battery starting performance drops in colder temperatures, which is why a weak battery may become more noticeable on a cold morning.
Heat can gradually damage a battery, while cold weather can expose a battery that is already weak. The following section of this article will discuss the effect accessories have on the battery.
Accessories and the Battery
Having additional accessories such as lights, GPS, alarms, and more can be beneficial to the rider. The rider should ensure that the accessories are installed properly. If the wiring looks messy or poorly done, it is best to have it checked before using the motorcycle.
If the battery dies only after installing accessories, it is best to look at them first. They may be drawing more power than expected or may have been installed incorrectly. The charging system should also be checked if the battery continues to lose charge.
The importance of not using the wrong battery is further discussed in the following section.
The Importance of Not Using Oversized Batteries
An oversized battery is not always a good thing. Some batteries may physically fit, but they may not match the electrical requirements of the motorcycle. When looking for a battery, it is best to stick to the size and specifications recommended by the manufacturer.
If the manufacturer recommends a 12-volt battery with a specific capacity and starting requirement, it is best to find a battery that matches those specifications. Physical dimensions, terminal position, polarity, battery technology and starting performance should also be considered.
A high-quality battery is recommended when looking to change the battery. The following section on batteries will discuss AGM and lithium batteries.
AGM and Lithium Batteries
AGM batteries are a practical choice for many riders. They are reliable, require little maintenance and are generally reasonably priced.
Lithium batteries provide performance and lightness, but they are not necessary for every rider. The weight savings can be useful for performance-oriented riders and track days.
If the rider decides to use a lithium battery, it must be compatible with the charging system of the motorcycle. A suitable charger or maintainer should also be used when required. The extra expense should also be considered before making the switch.
The next section of this article will discuss where to buy batteries.
Where to Buy
It is best to buy from reliable motorcycle shops rather than random websites. Riders should buy batteries from a reputable seller with good stock rotation, proper storage practices and a warranty where available.
This is best done at a reliable motorcycle specialist such as Baycity Powerparts. Riders can explore the motorcycle battery collection at Baycity Power Parts.
The final section will summarise everything discussed in this article.
Final Touch
Batteries are usually the forgotten part of a motorcycle until they fail. Many batteries have an expected life of roughly 2–5 years, depending on how well they are cared for, how the motorcycle is used and the conditions they operate in.
The rider can help prolong the life of the battery by keeping the terminals clean, keeping the battery properly charged and using a suitable battery maintainer during longer storage periods.
AGM batteries are a practical choice for many riders, while lithium batteries can be useful for riders looking for weight savings and performance benefits.
The rider should also be on the lookout for signs that point to battery failure. The rider should have the battery tested or changed if he notices slow starts, clicking sounds when starting, and dim displays.
A little attention to the battery can save a rider from a lot of trouble later.
