Buying Batteries Online
The internet is a great source for being able to find batteries for laptops, cameras, cell phones, . . . etc. Once you buy your item (camera or whatever) there is really no reason to go back to your original source for power supplies. For that reason you should feel free to buy batteries from anywhere online.
Even if never taken out of the original package, disposable (or "primary") batteries can lose two to twenty-five percent of their original charge every year. This rate depends significantly on temperature, since typically chemical reactions proceed more rapidly as the temperature is raised.
This is known as the "self discharge" rate and is due to non-faradaic (non-current-producing) chemical reactions, which occur within the cell even if no load is applied to it. Batteries should be stored at cool or low temperatures to reduce the rate of the side reactions. Extreme high or low temperatures also reduce battery performance.
Rechargeable batteries self-discharge more rapidly than disposable alkaline batteries, up to three percent a day (depending on temperature). Due to their poor shelf life, they shouldn't be left in a drawer and then relied upon to power a flashlight or a small radio in an emergency. For this reason, it’s a good idea to keep a few alkaline batteries on hand. Ni-Cd Batteries are almost always "dead" when you get them, and must be charged before first use.
Most Ni-MH batteries can be recharged 500-1000 times whereas Ni-Cd batteries can only be recharged about 400 times.
Automotive lead-acid rechargeable batteries lead a much harder life. Because of vibration, shock, heat, cold, and sulfation of their lead plates, few automotive batteries last beyond six years of regular use.
Special "reserve" batteries intended for long storage in emergency equipment or munitions keep the electrolyte of the battery separate from the plates until the battery is activated, allowing the cells to be filled with the electrolyte. Shelf times for such batteries can be years or decades. However, their construction is more expensive than more common forms. (Wikipedia)

Batteries may contain harmful metals and chemicals such as
nickel cadmium, alkaline, mercury, nickel metal hydride and lead
acid, which can contaminate the environment if not disposed
properly. For example, when batteries containing cadmium is used
in landfills, they will eventually dissolve and release the
