Its a samsung digimax A5/A53 - batteries are fully charged but still keeps telling me the same thing 'low battery'

I understand that your brand is Samsung, but you have listed this as a KODAK camera.

I don't know if this applies to Samsung products as well as a C875 KODAK camera. But I hope it helps if not. Please re-submit your question under the correct brand. Thank you. Trouble shooting is as following:

1. Make sure you will install a new or fully charged battery/batteries into your camera. Please use lithium batteries Ni-Mh or rechargeable Batteries (2000 M.Amp or higher).

2. Clean the battery contacts.
a. Remove the battery/batteries and the memory card from your camera, then wipe the battery contacts with a soft, clean cloth.
b. Reinstall the battery/batteries into your camera

3. Turn on your camera without the memory card.
