Don't pay $3 and up for a single battery - these are perfect for calculators, flashlight key chains, laser pointers etc. 

Please note that these are VERY low-priced batteries. While the majority will have plenty of power, you may find one or more 'duds' in the packet, so please be sure to test them before using them. This is still the best value way we've found of buying these otherwise expensive batteries.

Please check your equipment's requirements as we cannot advise compatibility with your gear.
