Anil asked:


I have 4 batteries with me.
I have been using for my CANON camera. My camera needs 2 at a time.

Among 4, i think 1-2 batteries are almost done with their job. How do i test all 4 batters and displose the battteries which are almost dead?

Some combinations works well and some gives only 2 mins backup. I dont want to try all 100 combinations. Any easy way?
