Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, because the chemical reactions in the batteries are slower.

A battery is a collection of two or more cells, but in popular usage battery often refers to a single electrical cell.

Battery size generally refers to the shape, voltage, and terminal layout of a battery. Thus the term "size" has become interchangeable with "type". Batteries of different types will usually not have the same dimensions and terminal layout.

Diamond Drilling or Exploration Diamond Drilling makes use of an annular diamond-impregnated drill bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock (core samples). Diamond size and matrix can be varied according to the hardness of rock needing to be cut. Holes within the bit allow water to be delivered to the cutting face. This provides lubrication, cooling, and removal of drill cuttings from the hole.
