They have a low self-discharge rate compared to NiMH batteries and are not subject to memory effect. They do not require regular discharging, thus requiring little maintenance. With proper storage, these rechargeable batteries are long-lasting, durable, and have many possible charging cycles. Li-ion batteries are used in various high-energy portable devices such as smartphones, notebook computers, cameras, and electric power tools. These batteries can also be used in radio-controlled models and telecommunications applications. Note: For lithium-ion replacement batteries with significantly higher capacity (1000 mAh and above) than the original battery, the replacement size may vary slightly, making it slightly heavier or thicker. As a result, the replacement battery may protrude slightly.; Compatible devices: Agfeo Dect 50, COMfortel M-200, COMfortel M-210, COMfortel M-310, Nortel Kirk 4080, Polycom 5020, Polycom 5040, Polycom Kirk 4080, Polycom Kirk 5020, Polycom Kirk 5040, Spectralink 3040, Spectralink 5020, Spectralink 5040, Spectralink 7202, Spectralink 7212, Spectralink 7502, Spectralink 7520, Spectralink 7522, Spectralink 7532, Spectralink 7540, Spectralink 7620, Spectralink 7622, Spectralink 7640, Spectralink 7642, Spectralink 7710, Spectralink 7720, Spectralink 7722, Spectralink 7740, Spectralink 7742, Spectralink Kirk 5020, Spectralink Kirk 5040 Aastra, Telrad 3040, Tunstall 7202 Dect Handset, Tunstall 7202P Dect Handset, Tunstall 7212 Dect Handset, Tunstall 7722 Dect Handset Polycom / Spectralink 84743424, Polycom / Spectralink 84743428, Polycom / Spectralink ICP73048
