How Long Does a Motorcycle Battery Last

On average:

• Traditional lead-acid motorcycle batteries last 2 to 5 years.
• AGM (Absorbent Glass Mat) motorcycle batteries typically last 3 to 5 years.

Based on extensive testing, Uplus AGM motorcycle batteries have an average lifespan of 5 years.

But should you wait for your battery to completely die before replacing it? Actually — no. There are early warning signs you can spot in everyday use to know it’s time for a new battery.

How Do I Know If My Motorcycle Battery Needs Replacing?

Starting to slow down on startup

Have you noticed your motorcycle struggling to start, especially on cold mornings? Typically, your motorcycle should fire up after one or two cranks. But if it takes three, four, or even five cranks before the engine kicks in — it’s a strong sign your battery is running low.

This issue becomes even more obvious in cold weather, as the starter motor requires more current to turn the engine over. If your bike is consistently hard to start, it’s likely time for a battery replacement.

Low Voltage

Another clear indicator is low battery voltage. Most modern motorcycles come with a built-in voltmeter. If yours doesn’t, you can easily check the voltage using a standard multimeter connected to the battery terminals, or buying a motorcycle voltmeter.

As a general, a healthy static voltage (engine off) should read between 12.2V and 12.5V. If it falls below this range, your battery is likely past its useful charge-discharge cycle and needs replacement. When the engine is running, the voltage should stay between 13.7V and 14.5V, depending on the bike’s electrical load.

While low voltage when the engine’s running could point to other electrical issues, it also helps indicate the overall health of your battery.

Electrical Performance Problems

If you experience weak cranking, dim headlights, or flickering instrument lights, it often points to a failing battery. Today’s powersports are packed with electronic features,  they pair all place higher demands on the electrical system of the motorcycle. Of course, the battery is at the core of it.

Typically, with proper use and maintenance, an AGM powersport battery lasts around 3 to 5 years. If your engine cranks slowly or the starter sounds weak, don’t wait for a roadside failure — replace your battery proactively.

Pick a Low Self-Discharge Powersports Battery

Self-discharge is the rate at which a battery loses power when not in use. Many factors affect this rate, but one of the most important is the manufacturing technology — including electrode processing, assembly, formation and testing, and sealing.

At Uplus Battery, a subsidiary of Leoch Battery, all products are made on advanced automated production lines under the highest industry standards. This ensures premium quality and a self-discharge rate of less than 3%, which translates into a longer battery life and slower power drain.

Choose the Right Size and Capacity

Uplus offers a wide range of motorcycle, ATV, and UTV batteries with different capacities (Ah), sizes, and starting currents (CCA). It’s important to select a battery that perfectly fits your vehicle’s specifications and starting power needs.
