Do lithium batteries lose charge when not in use?

No matter what type of battery it is or what material it is made of, it will drain the charge even when not in use. Similarly, when not in use, Lithium-Ion batteries will drain. If you charge the battery when it is completely discharged, you will reduce its capacity.

What batteries last the longest?

Lithium: Lithium batteries work even better than alkalines. They last much longer, have an epic shelf life, don't discharge as much power when not in use and can cope with extreme temperatures. While normal alkaline AAs struggle below 0°C, lithium batteries will operate down to -40°C.

Is a coin battery the same as a button battery?

Based on the shapes of these batteries we call them "coin" or "button" interchangeably, regardless of the chemicals inside. But there is an important difference between them: Coin batteries contain lithium, button batteries do not. Coin batteries (or cells) contain lithium chemistry and have a 3 Volt output.

What are the little round batteries called?

A button cell, watch battery, or coin battery is a small single-cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high — resembling a button.

What voltage is a coin battery?

Alkaline coin cell batteries have a nominal voltage of 1.5V. Lithium coin cell batteries, on the other hand, have a nominal voltage of 3V. Coin cell batteries come in a few different sizes, each with a specially coded name to indicate the size and chemistry.

Does keeping batteries in the freezer help?

In short: no. While cold environments help maintain battery life, refrigerators and freezers are not safe to put batteries in. The moist environment will cause condensation on the batteries. This in turn will lead to rust or other damage.
