I need batteries and connecting lines to use Sony camcorder for a long time. I also need to charge extra batteries.

Question

=====================================
Are the sentences above correct? Do you use connect lines? Do I have to use connecting cords? When we want to use electricity, we need connecting lines. Do I have to put 'the' before Sony camcoorder'?

Answer 1

I need extra batteries and cables to use my (the)(mother's)(aunt Sarah's) Sony camcorder for extended periods.

The use of "connecting" is optional, it is commonly understood that the cables are for connecting electricity.
