For How Long do Motorcycle Batteries Last?

Types of Batteries
September 5, 2018
 

Battery manufacturers all over the world will readily let you know that a motorcycle battery, on average, should last about 48 months.

However, the reality is a much shorter lifespan closer to 12 months. If you’re lucky.

 

In most cases, reduced battery life can be attributed to lack of maintenance or incorrect care, which makes it entirely possible to get more out of your battery if you understand what you’re working with. The lead/acid cell is the most common type of motorcycle battery. They’re referred to as flooded or wet cell batteries, that are basically individual cells connected in series – three for a 6-volt system, six for a 12-volt system – and grouped together in a shared container. Although these are the most common type of motorcycle battery, Valve Regulated Lead Acid batteries are an alternative that offers a better maintenance experience. Let’s look at what you need to know before making your final choice…


Because of the way in which flooded cell batteries are set up (in series) you end up with a battery that produces a cumulative voltage appropriate for its intended use. However, as the battery runs down, certain chemical changes occur within the electrolyte creating the electrical charge, and the lead plates that carry the current. The sulfuric acid in the electrolyte gets used up in a way, leaving behind only water, and lead sulfate begins to coat the lead plates inside the container, greatly reducing the battery’s efficiency. After a while, what you’re left with is a dead battery. One of the biggest drawbacks of flooded cell batteries is the basic make-up – extremely corrosive liquid housed within flimsy plastic, releasing highly explosive hydrogen gas as the battery is being charged. The charge/discharge of these batteries also leads to the evaporation of water, which requires regular topping up to ensure the cells work the way they’re supposed to, and last as long as they should. If this maintenance is neglected, the battery will lose its ability to hold a charge for very long.


Valve Regulated Lead Acid batteries (VRLAs) or sealed batteries are available as either Absorbent Glass Mat (AGM) batteries or Gel batteries. Sharing some similarities with flooded cell batteries, the distinctions that sets VRLAs apart are significant and worth considering a change from the previously accepted norm. For starters, VRLAs make use of calcium alloy plates instead of lead. What this means is that no hydrogen is produced during a charging cycle and whatever oxygen is produced gets used back up the system to form water. In short, due to the intricate chemistry of VRLA batteries, you never need to add water. And like a wise man once said – the best kind of maintenance is no maintenance. AGM batteries incorporate high quality glass fiber along with calcium alloy plates, which results in far greater efficiency and higher current production than flooded cell batteries. They also hold their charge for longer.


The bottom line for extended battery life is that of maintenance. Know what to do, and don’t neglect to do it.


  1. Start with choosing the right battery for your bike. You can use this article as a guide if you need some help.
  2. Once per month, make sure you check the fluid levels of your battery. In flooded cell batteries, lost water needs to be topped up on a regular basis, so this step is especially important if this is the battery you’re using.
  3. Cleaning your battery is the next maintenance step. Grime, pollutants, and dust will accumulate on your battery over time. If left untended, these contaminants can lead to corrosion. Some battery cleaner and a clamp brush is all you need to eradicate build-up of dirt and preserve the housing for longer.
  4. Most motorcycle batteries don’t deal well with cold. During winter months, always remove your battery and store at room temperature to prevent freezing and possible cracking. Storing on metal or concrete will cause the battery to discharge, so rather opt for wood or any other warm surface.
  5. Use a motorcycle battery charger to keep your battery optimally charged, especially during winter months.
