Seller what is the difference between yellow/ black long lasting & red/ black max aaa alkaline batteries?

Yellow (Alkaline Power) are not as good as red (max), or the blue (max+). Yellow is good for low current things like remotes or low power LED lights. For high power lights or things with motors, the red max will be better. Depends on cost, though. If these are cheaper enough they will still be a good value. How much cheaper they need to be depends.

Can anyone tell me the exact wide? Need to place them in artifical candlesticks and some Double AAs are a little too wide?

These are AAA and I use them in my artificial candlesticks they are 1 centimeter wide and almost 4 and a half centimeters long.

Are these generic? Energizer only lists the Max on their website and I cant find these anywhere else.
