Canon battery charging time depends on the battery type and charger you use

Most Canon batteries take between 1.5 and 3 hours to charge fully, but the exact time varies based on which battery model you own and which charger you're using. Smaller batteries like the NB-13L charge faster — usually around 1.5 to 2 hours — while larger batteries like the LP-E6NH can take 2.5 to 3.5 hours. Canon also makes fast chargers that reduce these times by 30 to 50 percent, though they cost more upfront.

The charger matters as much as the battery. A standard Canon charger designed for a specific battery will charge it in the manufacturer's stated time. Third-party chargers vary widely — some are faster, some slower, and some may damage the battery if they're not designed properly. If you're buying a replacement charger, matching it to your battery model gives you the most reliable charging speed.

Key Takeaways

  • Standard Canon chargers take 1.5 to 3 hours depending on battery capacity, with smaller batteries charging faster than larger ones.
  • Fast chargers like the LC-E10 reduce charging time by roughly half, though they cost more than standard chargers.
  • The charger model matters — using a charger not designed for your battery can result in slower charging or potential battery damage.
  • Charging time also depends on the power outlet's voltage and the charger's condition; older chargers may charge more slowly.

Charging times for common Canon battery models

Canon makes batteries in several sizes for different camera types. Compact camera batteries like the NB-13L (used in PowerShot models) charge in roughly 1.5 to 2 hours with a standard charger. The NB-6L, found in older PowerShot cameras, takes about 2 hours. These smaller batteries hold less charge, so they reach full capacity faster.

Mirrorless and DSLR batteries are larger and take longer. The LP-E6NH (used in Canon EOS R and 5D Mark IV cameras) takes 2.5 to 3 hours with a standard charger. The LP-E17 (found in EOS M and some entry-level DSLRs) takes about 2 to 2.5 hours. The LP-E8 takes roughly 2.5 hours. If you own multiple Canon cameras, you likely have different battery models, and each one has its own charging window.

The charger's model number usually matches or relates to the battery model. A CB-5L charger works with LP-E6 batteries, a CB-2LW works with NB-6L batteries, and so on. Checking your charger's manual or the label on the charger itself tells you which batteries it's designed for and how long charging should take.

How fast chargers reduce charging time

Canon's fast chargers, like the LC-E10 and LC-E10E, cut charging time roughly in half. An LP-E6 battery that takes 3 hours on a standard charger may take 1.5 to 2 hours on a fast charger. The trade-off is cost — fast chargers typically run $40 to $60, compared to $20 to $30 for a standard charger.

Fast chargers work by delivering more power to the battery during charging. This is safe when the charger and battery are designed to work together, but it does generate more heat. If you charge frequently or need to turn around batteries quickly (for example, if you're shooting an event and need a backup battery ready), a fast charger pays for itself in convenience. If you charge overnight or have multiple batteries rotating, a standard charger is usually sufficient.

Factors that affect how long charging takes

The outlet voltage in your location can slow charging slightly. In countries with 110V power (like the United States), charging may take a few minutes longer than in 220V regions (like Europe or Asia). This difference is usually small — 10 to 15 minutes at most — but it's worth knowing if you travel internationally with your camera.

The charger's age and condition also matter. An older charger that's been used for years may charge more slowly than a new one, even if it's the same model. Chargers can degrade over time, especially if they've been exposed to heat or moisture. If charging suddenly takes noticeably longer than it used to, the charger may be wearing out.

Battery condition plays a role too. A battery that's been stored for months or years may charge more slowly on its first use, then return to normal speed. Batteries that have been fully drained repeatedly may also charge slower than new batteries. This is normal wear and doesn't mean the battery is broken, but it does mean you'll wait a bit longer.

What to do while your battery charges

Most Canon chargers are small enough to carry in a camera bag, and they work with standard wall outlets. You can charge while you're working at a desk, traveling, or between shooting sessions. Some chargers have a light indicator that shows charging status — usually green when done, red or amber while charging.

If you're shooting regularly, owning two batteries and rotating them is more practical than waiting for one to charge. Buy a second battery that matches your camera model, and keep one charging while you use the other. This way you're never without a backup, and you don't have to stop shooting to wait for a charge.

Using third-party chargers and what to watch for

Third-party chargers designed for Canon batteries exist and are often cheaper than Canon's own chargers. Some work well and charge at similar speeds to Canon chargers. Others charge more slowly or may not charge certain batteries fully. A few low-quality chargers can damage batteries if they don't regulate power properly.

If you buy a third-party charger, check the reviews from people who own the same battery model you do. Look for mentions of charging speed and whether the battery charges to full capacity. Avoid chargers with no brand name or reviews, as these are more likely to have problems. When in doubt, a Canon-branded charger costs a bit more but removes the guesswork.

Frequently Asked Questions

Can I charge a Canon battery in a different charger than the one it came with?

Only if the charger is designed for that battery model. Canon batteries have different connectors and power requirements depending on the model. Using the wrong charger can result in no charge at all, slow charging, or potential battery damage. Check the charger's label or manual to confirm it supports your battery before using it.

Why is my Canon battery charging slower than usual?

The charger may be aging, the outlet voltage may be lower than normal, or the battery itself may be worn. Try charging in a different outlet or with a different charger if you have one available. If a new charger still charges the battery slowly, the battery itself may need replacement.

Is it safe to leave a Canon battery charging overnight?

Yes. Canon chargers have built-in protection that stops charging once the battery reaches full capacity, so leaving it plugged in overnight won't overcharge or damage the battery. The charger simply stops delivering power and waits. This is safe to do regularly.

Do fast chargers damage Canon batteries?

No, not if you use a fast charger designed for your specific battery model. Canon's fast chargers are engineered to work safely with their batteries. The risk comes from using a fast charger designed for a different battery type or from a brand with poor quality control. Stick to chargers made for your battery model.

How do I know which charger works with my Canon battery?

The battery model is printed on the battery itself (like LP-E6NH or NB-13L). Search that model number plus "charger" to find compatible options. Canon's website lists which chargers work with each battery. If you have the original charger, its model number is on the label, and you can match it to your battery in Canon's documentation.
