Canon batteries: average battery life expectancy

How long does a Canon battery last? The average digital camera’s battery life of a fully charged Canon battery depends on the specific model, but most batteries will last 3-5 years with normal use before needing replacement.

Of course, there are a few things you can do to maximize battery life and get the most out of each charge. First, avoid draining your battery completely if possible. Doing full discharges too often can reduce the overall battery life over time. Try to recharge when your battery reaches around 20-30% remaining.

Second, don’t leave batteries sitting in a hot environment like your car on a summer day. The heat will speed up the aging process of the cells inside the battery and decrease its lifespan. Room temperature storage is best.

It also helps to avoid “trickle charging” which is leaving the battery plugged in and charging 24/7. Only recharge your batteries when they require it. Leaving them plugged in constantly can reduce their ability to hold a charge over time.

Finally, if you’re not using your camera equipment for an extended time, remove the batteries from the devices. Batteries left sitting inside digital cameras or other electronics for weeks or months at a time can slowly drain and lose capacity.

By following these tips, the average Canon camera battery last for 3-5 years before needing replacement. But when your battery life starts noticeably dropping off or isn’t holding a charge as long, it’s probably time to invest in a fresh new set of batteries. Your camera gear will thank you!

Factors that affect a Canon battery’s lifespan

How long does a Canon battery last, depends on several factors. How you use and preserve battery life has a big impact on how long a decent camera battery lasts before requiring replacement.

Battery type

The specific kind of battery you have matters. Canon LP-E6 batteries used in many DSLR cameras typically last 2-3 years, while NB-13L batteries for PowerShot cameras may only last 12-18 months. The battery’s capacity also affects lifespan—higher capacity means more charge cycles before the performance starts to degrade.

Charge cycles

Batteries can only be recharged a limited number of times before they lose the ability to hold a charge. Most batteries can handle 300 to 500 charge cycles before requiring replacement.

The more often you drain and recharge your battery, the faster it will reach the end of its useful life.

Storage conditions

How you store your battery when not in use directly impacts its lifespan. Batteries slowly discharge when stored, and heat accelerates self-discharge. Storing batteries in a cool environment can double their lifespan. Never leave batteries in extreme heat, like a hot car. Charge batteries to about 40% before storing them long-term.


Frequent use and deep cycling—draining your battery close to empty before recharging—can shorten its lifespan. If possible, avoid fully depleting your battery with each use. Also, avoid leaving a battery in your camera for long periods when not in use.

If you are using a mirrorless shooter from Canon, you have no way out but to rely on the Electronic viewfinder, which is a massive battery drainer. However, for DSLRs, you can always rely on the optical viewfinder to save battery life without sacrificing performance.

By following these best practices for using and storing your batteries, you can maximize their lifespan. Be prepared to replace them every 1-3 years for the best performance and to avoid getting caught without power. Using older, worn-out batteries could damage your camera or prevent it from operating properly.

Tips to maximize your Canon battery life

Now you know how long does a Canon battery last so that you can get the most out of your Canon camera batteries, follow these tips:

Avoid fully draining batteries

Only discharge batteries to about 50% before recharging them. Fully draining batteries can reduce their lifespan.

Keep batteries at room temperature

Extreme heat or cold reduces battery performance and longevity.

Take the batteries out of your camera if storing it in very hot or cold conditions.

Don’t leave batteries in the charger for days

Only charge batteries until the light turns green, then remove them. Leaving them in the charger continually can reduce their lifespan.

Use the camera’s battery power-saving features

Turn off the image preview, reduce brightness, and shorten the auto-off timer. The less power your camera uses, the less it drains the battery.

Have backup batteries

Always carry fully charged spare batteries, especially if you plan to be away from power sources for a long time.

Backup batteries allow you to keep shooting even when your main batteries die.

Recharge batteries before storing long-term

Partially drain and recharge the batteries before putting your camera into long-term storage. Storing batteries in a discharged state can reduce their ability to hold a charge over time.

Consider using third-party batteries

Third-party batteries are often much more affordable than name-brand batteries. Look for batteries from reputable brands that are specifically designed to replace your batteries. They can work just as well as the name-brand versions.

Recycle old batteries properly

When batteries no longer hold much of a charge, dispose of or recycle them according to the local regulations in your area. Never throw batteries in the trash.

Following these tips will help you maximize the performance and lifespan of your Canon camera batteries, so you can keep shooting for years to come.

With some TLC, your professional camera batteries can serve you well for a long time.
