How We Decided
In order to narrow down our choices for the best motorcycle batteries, we limited our search to fully sealed, maintenance free AGM motorcycle batteries. Using absorbed glass mat technology, these batteries are far safer and easier to keep up than the old style wet lead acid batteries. Most OEM motorcycles these days use AGM motorcycle batteries.
We also only looked at batteries that met OEM specs for voltage and cranking amps for their intended applications. This way, you can be sure the replacement motorcycle battery you buy will start your bike as easily as the original.
In making our selections for the best motorcycle battery for Harley Davidson, we narrowed it down to batteries that met or exceeded factory specs and that were specifically designed for vibration resistance and external durability.
Best Motorcycle Battery Buying Guide
Features to Consider
Motorcycle batteries come in wet cell lead acid, gel electrolyte, absorbed glass mat and lithium ion. Lithium motorcycle batteries are typically rated for a larger number of recharging cycles but are more expensive. Old-style wet cell batteries, the oldest form of car and motorcycle battery used, contain lead and lead oxide plates in a sulphuric acid and water solution; since they’re not fully sealed, however, they need to be topped off with distilled water once in a while, and they may be sensitive to vibration and orientation. Gel cell batteries have the electrolytes suspended in a gel, and are more resistant to vibration and heat. AGM or absorbed glass mat batteries are similar to gel batteries but use glass fiber sponges between the electrolyte plates, allowing for more control over the acid movement between them, and thus smaller batteries for the same amperage. For these reasons most motorcycles use AGM batteries.
When looking for the best motorcycle battery for Harley, Suzuki, Honda, Triumph or other bikes, first make sure the batteries you’re looking at will fit your make and model.
CCA, or cold cranking amps, refers to the maximum number of amps the battery can produce in 30 minutes at 0º Fahrenheit. When looking for the best motorcycle battery for cold weather, look for a CCA rating of at least 380-400.
Most modern motorcycles have a 12V electrical system, but always make sure the replacement battery matches the voltage requirements of your bike.
Motorcycle Battery FAQs
What is the average life of a motorcycle battery?
While it all depends on usage and environmental conditions, the best motorcycle batteries should typically last anywhere from three to five years of regular riding use. Many motorcycle battery brands post a rating for the number of charging cycles. Chrome Pro batteries, for example, are rated for at least 2000 charging cycles.
Will a USB charger drain a motorcycle battery?
While the draw from a USB charger plugged into a 12V to USB converter is very small, you shouldn’t leave devices plugged in while stopped for more than a few minutes, or your USB converter in place overnight. Especially when using devices like GPS units and speakers, try not to leave the accessories on for very long while stopped.
What charges a motorcycle battery when driving?
Motorcycles use an engine-driven generator to provide charge to the battery while driving, similarly to how a car uses an alternator to provide a constant voltage charge to its battery.
How to install a motorcycle battery?
Removal and installation of a motorcycle battery is relatively straightforward in most cases. Locate the battery, use the right size socket to remove the negative/ ground terminal bolt, then make sure you secure the negative cable away from the positive cable or other metals, and undo the positive terminal bolt in the same way. Remove the battery and check to see if the cable ends or the battery tray need cleaning. To install a new battery, insert the nuts the new battery comes with, then position the battery in place, then attach the positive cable first, then the negative cable.
Are gel motorcycle batteries better?
Depending on what kind of bike you have, a gel electrolyte motorcycle battery could be an upgrade. If you have an older bike that came with a wet cell battery, a gel motorcycle battery will provide better reliability and last longer without needing any maintenance. However, most modern bikes come with AGM or absorbed glass mat batteries, which have the benefits of a gel motorcycle battery while being even more robust and more compact.
What type of battery is a motorcycle battery?
Most motorcycles on the road today use sealed 12V batteries, and the most common type is an absorbed glass mat or AGM motorcycle battery.
How do I choose a motorcycle battery?
First look for the right fit; many motorcycle batteries are specific to certain models, and the best battery for Harley Davidson motorcycles may not fit a Triumph or Honda. Make sure the battery is the correct voltage and has enough cranking amps to start your bike. If you live in a cold climate look for the cold cranking amps or CCA rating as well, which can usually be found in a motorcycle battery comparison chart.
Why do motorcycle batteries die so fast?
The best motorcycle batteries can often last a decent length of time, from two to five years on average. However, many do find that motorcycle batteries die more quickly than car batteries. This may happen because motorcycles sit parked for longer and go on shorter drives, on average, giving the batteries less time to recharge and more time to slowly drain.
