Following its recent appointment to represent the components division of Seiko Instruments (SII) in the UK and Ireland, Ismosys has released details of a new coin-cell lithium rechargeable battery that offers a much higher operating temperature than conventional rechargeable batteries. While the maximum operating temperature for conventional rechargeable lithium batteries is 60ºC, SII has successfully applied its sealing technology to increase the operating temperature of the new MS920T coin-cell Lithium rechargeable battery up to 85ºC
MS920T Key features
- High operating temperature (85º C)
-
Exceptional power retention
– retains more than 90% of initial capacity after 60 days of storage at 85ºC -
Excellent over-discharge characteristics
– retains characteristics even after being over-discharged to 0V. - Long cycle life – can be charged and discharged more than 100 times with 100% depth of discharge (3.1V to 2.0V)
The design of the new battery has been optimised to meet the requirements of demanding exterior and interior applications.
According to Ismosys MD Nigel Watts, elevated temperatures accelerate the deterioration of conventional lithium rechargeable batteries: “In contrast to conventional type batteries, which rapidly lose up to 40% of their initial capacity at 85º C, SII’s new MS920T new coin-cell lithium rechargeable battery retains more than 90% initial capacity under the same conditions,” Watts said.
MS920T Key Specifications
- Nominal Voltage 3V
- Nominal Capacity 6.4mAh
- Internal Impedance 60O
- Physical: Diameter 9.5mm, Height 2.0mm, Weight 0.45g
- Operating temperature range -20º C to +85º C
The MS920T coin-type lithium rechargeable batteries will find ready applications in digital still cameras, security and dashboard cameras, thermostats, GPS, and as a power backup for real time clock and memory.
