What this battery powers

The Canon NB-15L is a rechargeable lithium-ion battery built for compatible Canon cameras such as the PowerShot G7 X Mark III and PowerShot SX740 HS. It serves as a primary, replacement or backup power source for photographers who need reliable energy during extended shooting sessions or travel.

Heat noise and power in use

The cell delivers a steady 3.6V output with a 4.5Wh energy rating, providing consistent power without excess heat during normal camera operation. Its compact design adds no audible noise and draws only the current the camera requires for stable performance.

Capacity that decides fit

At 1250mAh this battery determines how many frames or minutes of video you can capture before recharging, making it the key figure for deciding whether it meets your shooting demands. Buyers who need longer runtimes than this single cell provides will require additional batteries.

Questions about this item

How do I install the NB-15L battery in my PowerShot G7 X Mark III, and what is the common mistake?

Open the battery/memory card cover, insert the NB-15L with the Canon logo facing up and contacts inward until it clicks, then close the cover. The step people get wrong is inserting it upside down, which prevents the latch from engaging.

What maintenance or replacement will the NB-15L need over time?

The 1250mAh Li-ion cell gradually loses capacity after hundreds of charge cycles; expect shorter runtimes after two to three years of regular use. Store it at roughly half charge in a cool place if unused for weeks to slow ageing.

What limit appears first during sustained shooting with the NB-15L in an SX740 HS?

The 4.5Wh capacity typically runs out after extended 4K recording or continuous burst shooting, so the battery depletes before the camera hits thermal throttling or buffer limits.
