Batteries for Canon digital cameras can be a standard set of AA batteries or their rechargeable counterpart. Battery life of these varieties may differ depending on the frequency of use. Special lithium ion battery packs are also available. These battery types occupy a smaller space compared to the space in use of four AA batteries. The drawback with lithium ion batteries is that you can’t just insert in ever-present AA batteries when the cells run dry. You have to recharge them in order to be capable for usage.
Batteries for canon digital cameras always come with a warranty during purchase. Some stores and manufacturer’s promise replacement that is 100% compatible with the product. Some of them even come with a 30-day money back guarantee and one year of quality assurance.
The battery of the camera is the life of the camera itself. Without an efficient working battery, there will be less chance of capturing all the images and moments that you intend to take a shot.
