Before investing in a motorcycle battery, or if you have already invested, you should know the factors that affect the battery life. There can be several factors. The critical five are-

5 Factors That Affect Battery Life 

  • Type of the battery

There are different types of batteries like wet cell batteries, gel cell batteries, AGM batteries. The battery that comes with less maintenance should be the preferable one.

  • Weather condition

Weather condition is one of the significant factors that affect battery life.

If the weather is cold or rainy, the battery charge will go down. Even there is a possibility that the battery might not start at all.

  • Battery Usage

More usage of motorcycles ensures more use of the battery, which elongates the battery life. If a battery sits ideally for a long time, the charge goes down and reduces the battery life.

  • External charge

When the weather is cold, or the motorcycle is not used frequently external charger should be used to charge the battery. This keeps the battery going for a long period.

  • Taking care of terminals

The built-ups on the terminal of the batteries can hamper the charge flow. This tempers the battery life.

Taking Care of Motorcycle Battery

How long does the motorcycle battery last if you take care of it? A motorcycle battery has a lifespan of two to four years. 

However, you can expand the lithium battery’s life by using a few simple tricks. You won’t have to be concerned about your battery life when driving. Here are a few pointers to help you maintain and take care of the lithium-ion battery.

  • Battery Storage

When your bike’s spending most of its time in the shed, unplug the battery and keep it that way until you’re ready to hit the road. However, make sure to charge the battery even when it’s unplugged. You can use a motorcycle battery charger for the job. Otherwise, the cell’s electrolytes will dry up, leaving you hung and dry with a dead motorcycle battery. 

  • Charging Motorcycle Battery

Just like you wouldn’t last long without food, your motorcycle battery’s the same way. You need to charge your bike’s battery on a regular basis. More so if you don’t ride your bike every day. 

You can use a smart battery charger to do the job depending on your battery’s model. But, generally speaking, you need to charge the battery at twelve volts and maintain regular charge cycles. 

  • Weather condition

One easy trick to maintain the health of your motorcycle’s battery is to regulate the temperature. Extreme fluctuations in the temperature can have detrimental effects on your bike’s battery. You can’t control the cold weather, of course. But what you can do is store your mechanical tiger under the shed. 

Or, if it’s in winter or you’re in cold temperatures, park your bike in a heated garage. The climate-controlled garage will prevent any vapor loss and help the battery hold its charge, leading to a longer lifespan. 

6 Steps In Taking Care Of Your Motorcycle Battery

Taking care of your motorcycle battery might seem like a matter of hassle. But with the following six steps, you can have a battery with longer life. 

  • Visually Inspect Your Battery

While people say not to judge a book by its cover, the visual aspect of your bike’s battery is quite essential. So, at least once per month, visually inspect your battery. Regular inspection will give you a rough idea about the condition of the terminals and electrolytes inside the battery.

  • Cleaning the Terminals

The importance of keeping your battery’s terminals clean can’t be stressed enough. If the positive or negative terminals aren’t clean, the battery can corrode and lose a significant amount of its usual longevity. So, make sure to clean the terminals properly for a smooth operation. 

  • Make Sure the Connectors Are Not Loose

It’s annoying when your bike doesn’t want to start. This incidence can occur due to loose connectors or corroded battery terminals. If you’ve ever been in an accident, check your connectors to see if they’re connected. 

  • Check for Leakage 

Water is poison to your bike’s battery. And if there’s any leakage in the battery, water can get in. So, check for any leakages before you hit the road. That is if you don’t want your bike to die on you. 

  • Check the Water Level

Always make sure that your battery’s water level is sufficient. If necessary, use distilled water to fill the batteries to keep an adequate level of electrolytes.

  • Keep It Charged

We can’t stress this point enough. Keep your battery charged if you want it to serve you well for long periods of time time. Otherwise, you may end up with a dead battery sooner than you think.

Frequently Asked Questions (FAQs)
