Compact cameras and DSLRs are usually powered by rechargeable Li-ion batteries. You can choose from original and non-original, i.e. alternative batteries, which are cheaper but may not be fully compatible with the camera body. Take note, however, that some devices still need the so-called AA batteries.

Battery Types
Original
- Same manufacturer makes both the camera and the battery
- Usually more expensive than non-original batteries
- Provide 100% compatibility with your camera's body
- Tend to have a longer service and higher number of charging cycles
Non-original
- May have a higher battery capacity than original batteries
- This is offset by often shorter service life
- May not be 100% compatible with the camera body
Key parameters when choosing a battery for your camera
Choosing the right battery
When shopping for a replacement battery, always follow the camera manufacturer' s specifications, preferably listed on the original battery itself or in the user manual. When choosing a battery, the type designation of the battery is always important (eg LI-40B), as well as the voltage, which is given in volts (V) and battery capacity (mAh).
Battery capacity
Indicated by the mAh value. Standard camera battery capacity ranges from 1,000 to 1,400 mAh. The higher the capacity, the more pictures you can take.
- Battery capacity up to 950 mAh – common for compact cameras and mirrorless cameras. Allows you to take up to 350 photos on a single charge.
- Battery capacity over 1000 mAh – typical for DSLR cameras. Allows you to take up to about 500 pictures on a single charge.
