Some cordless phones formerly advertised as 5.8 GHz actually transmit from base to phone on 5.8 GHz and transmit from phone to base on 2.4 GHz or 900 MHz, to conserve battery life. The 1.9 GHz band is used by the DECT 6.0 phone standard and is considered more secure than the other shared frequencies.
A lithium primary battery, not interchangeable with zinc types. A rechargeable lithium-ion version is available in the same size and is interchangeable in some uses. According to consumer packaging, replaces (BR) 2 ⁄ 3 A. In Switzerland as of 2008, these batteries accounted for 16% of lithium camera battery sales. [75]
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Cordless phone. The term cordless is generally used to refer to electrical or electronic devices that are powered by a battery or battery pack and can operate without a power cord or cable attached to an electrical outlet to provide mains power, allowing greater mobility. [1]
A lithium polymer battery, or more correctly, lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly, and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. Highly conductive semisolid polymers form this electrolyte.
