The batteries in film cameras are mostly small-cell batteries or LR44 alkaline batteries. They tend to stay for a long time since they are not continuously drained, but it’s important to check and replace them periodically to ensure accurate focus and exposure.

3. Disposable Cameras

A distinct category in the field of photography is disposable cameras. They are the best choice for trips, events, and one-time uses because they are affordable and for one-time use only.

Batteries in Disposable Cameras

Batteries are indeed required for disposable cameras. These cameras typically have built-in flashes, and in order for the flash to highlight your subjects in dim lighting, it needs to be powered. Disposable cameras often come with built-in batteries that last the duration of the film. Therefore, you need not worry about replacing them.

Which batteries do you need—rechargeable or disposable?

Given that most cameras require batteries, let’s address the age-old conundrum of choosing between rechargeable and disposable batteries for your camera.

Rechargeable Batteries


  • Rechargeable batteries can be used hundreds of times, reducing the number of disposable batteries that end up in landfills. They are also environmentally friendly.
  • Rechargeable batteries have a higher upfront cost, but they save money in the long run as you don’t need to keep buying disposable batteries.
  • You can recharge them whenever they run out of power, ensuring you never miss a moment.


  • Rechargeable batteries have a limited number of charge cycles. As time goes by, they may lose their capacity and need replacements.
  • The initial cost of purchasing a charger and rechargeable batteries can be higher than that of buying disposable batteries.
