Are you going to need batteries with that? Which brand to buy...

If batteries are not included - don’t waste your money on a pack of duds. 

Consumer Reports put AA batteries to the test and found a significant difference. Lithium batteries performed much better than the alkaline, especially in cameras, which can drain a charge quickly. However, alkaline cost a lot less and can work just fine for low-drain devices like flashlights and remotes. 

The best performing lithium was the Energizer and the longest lasting alkaline was the Duracell. In some cases, those big-name brands lived almost twice as long as the bargain brand.
