STB-A For Multi-Cell
It enables long time use through efficient power management by providing more accurate information than others already realized by other companies to main body and informs accurate remaining time (minute unit, capacity unit) to use.
STB-B Multi-Cell
1. Power-off time can be estimated for document working and wireless communication by exactly checking remaining power of battery
2. Usable time can be extended by communicating optimum power management condition with main body.
3. It enables maximum charging by checking remaining power until full charging while charging, and charging status
can be checked through monitoring.
4. It can display the remaining level of battery in the unit of minutes or %, not a bar graph. You can accurately predict
the remaining time of use.
5. Extended battery life. If you can check the battery status accurately, you can take advantages of your habit in using
a device or 100% charging to prevent a sudden thermalization of the battery and increase the life cycle.
6. Protection circuit function
7. Data storage function ? Battery capacity, remaining level/charging counts, battery types and maker information are
stored in the flash rom(Can update over the internet).
8. You can accurately estimate the status of each battery including the cell monitoring IC for multi cells.
