High Energy NiMH Button Cells

Bluetooth System
Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, GPS receivers, digital cameras, and video game consoles over a secure, globally unlicensed Industrial, Scientific, and Medical (ISM) 2.4GHz short-range radio frequency bandwidth. One of the earliest and most popular applications are wireless headsets for mobile phones.

Battery challenge
Weight and size are the most important features for a wearable headset followed by long usage time (standby and talk) as well as long shelf life and availability in charged state.

Technical solution
The V70HE cell out of the new HighEnergy family of Ni-MH button cells from VARTA Microbattery is specially designed for high energy density, low weight, high stability as required by wireless applications. Next generation of Bluetooth chipsets for mono headsets require voltage levels of 2.2-2.4V and open the door for high power, low cost Ni-MH button cell solutions.

Bluetooth Battery
VARTA Microbattery’s Ni-MH HE batteries (HighEnergy family) offer rechargeable battery solutions with reliable power for supplying new-generation Bluetooth chipsets.
Recommended configurations: 2/V70HE or 3/V70HE
