C batteries are standard cylindrical batteries bigger than AAA and AA dry cells but smaller than D cells. The terminal posts are threaded 8–32 ( Unified Thread Standard), insulated terminal nuts are normally provided, conical profile helical spring terminals are added for specific applications. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry. In the following table, sizes are shown for the silver-oxide IEC number; types and capacity are identified as "(L)" for alkaline, "(M)" for mercury (no longer manufactured), and "(S)" for silver-oxide.

If one is readily available, it makes sense to use it, but otherwise, a simple drop test can reveal the condition of alkaline batteries. This is because the chemical reaction they use to produce electrical energy generates a relatively stable voltage output until the chemicals are depleted. Combining a carbon-zinc anode for high power density with a manganese dioxide cathode ensures great longevity even when not in use! Some rechargeable batteries are built into the device that they power while removable models require a separate adapter or size C battery charger for the charging process. Touch the black clip to the positive side and the red clip to the negative side of the battery to read the voltage.Usually, when you purchase a rechargeable C size-battery it comes with a separate charger for your convenience. R14 batteries, otherwise known as C-batteries, belong to the dry cell group and are capable of operating in low moisture conditions, making them portable and perfect for use with low-power devices. The new cells will then force discharge the weakest one to its lowest voltage levels, increasing leakage potential. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics.

The UM2 batteries are specially crafted for optimal safety—low moisture content and built-in protection against overcharging, discharge, and short-circuiting. The most familiar dry cell battery sizes are AA and AAA, however, these are smaller than size C batteries which means that they have a more limited lifespan. It’s important to keep safety in mind though: avoid dropping the battery or leaving it out too long at hot or cold temperatures – otherwise, short-circuiting may occur that could lead to leaking!

These came in two incompatible sizes, as is evident in some of the pictures below, those on larger, mostly older, battery types such as the PP9 being somewhat larger than those on the smaller batteries such as the PP3.
