Telephone Batteries Key Terms
Learn some of the terms you may encounter when researching telephone batteriesAn electrical battery is any device which stores chemical energy and releases electrical energy. The term "battery" originally referred to the fact that these devices frequently use more than one cell, although the term has now broadened to include single cells. Telephone batteries have additional requirements over general purpose batteries, such as being small and rechargeable. A rechargeable battery may be known by other terms, such as a secondary cell or storage battery, and is able to be restored to a full charge by a compatible battery charger.
Built-in thermostatA battery with a built-in thermostat will shut off when its temperature exceeds a specified limit. The small size of a telephone battery makes overheating an important design consideration.
AlkalineAn alkaline battery is common in devices such as telephones, which require continuous current for long periods of time. Alkaline batteries are able to deliver as much as twice the current of a conventional battery of the same size.
CycleA battery cycle is the process of discharging a battery from a fully charged state to a specified level of discharge. In the particular case of telephone batteries, this charge level is frequently 90 percent of the battery's maximum capacity.
Lithium Ion (Li-Ion)Li-Ion batteries use cells composed of the element lithium to store chemical energy. Cell phones most often use Li-Ion batteries because they can store more electrical energy than other battery types of the same size.
Nickel cadmium (NiCd)NiCd batteries are commonly found in many different types of electrical devices, such as telephones. They are rechargeable and frequently last for 700 cycles.
