Batteries

If you want a small battery for powering a low energy product or keeping a real-time clock (RTC) running, have a look at coin cells.

Coin Cell Batteries
Coin cell batteries (a.k.a. buttons cells or watch batteries) are a small, low energy and low power battery that can power small devices. They are commonly used in small, low-power consumer electronics such as calculators, remotes, and key fobs. They are also fitted to PCBs as backup batteries for things like real-time clocks (RTCs).

Zinc-Air Batteries
Zinc-air batteries are batteries characterised by their use of zinc and a reaction with atmospheric oxygen. There is both non-rechargeable (primary) and rechargeable (secondary) zinc-air batteries, although the primary batteries are far more common.

Lithium Thionyl Chloride Batteries
Lithium thionyl chloride batteries are non-rechargeable batteries that are good for long-term power applications such as wireless remote sensors, backup power for non-persistent memory ICs, and real-time clocks.
