I have bought one battery backup/energizer/secondary power source (2500 mAh). I am going to India this week but not sure whether I can carry battery backup on flight. The website of Air Canada does not specify whether a battery backup is allowed on flight.

To make it more clear for you I have attached the images:

    What is a "battery energizer"? Around here "Energizer" is a brand name for non-rechargeable batteries. Do you mean a charger for rechargeable batteries? Or (guessing wildly) an UPS? Mar 21, 2016 at 17:31

    These items are sold at the tax free shops in airports, so you would not expect problems. Mar 21, 2016 at 20:25

    Except it was closed 4 hours after the asker explained what these are using comments, two hours after a commenter had pointed out that these well-known items are commonly sold in airports, and an hour after Howdedo had linked to the duplicate. It's not "the community did not understand", it's a small harmful minority of up to five users failing to read comments. Mar 22, 2016 at 14:49
