There are two types of batteries on Helios64 board:
- Li-Ion
- Coin-type Battery (CR 1225)

### Notes related to battery
## Notes related to battery
**To Be Confirmed**
We have NOT confirmed the operaiton of the RTC without CR1225 Coin Cell Battery, even in the situation with the Li-Ion connected we have NOT the operation of RTC.
!!! note
To be confirmed whether RTC is still running with Li-Ion battery only.
The Li-Ion battery design is not for powering device when the main AC supply is disconnected, but as the device support to perform graceful shutdown or hibernate.
Therfore if you found this device can actually turned on for a while when you push the power button, in the situation the Li-Ion battery is connected (when the main AC power disconnected), this is totally normal situation.
The Li-Ion battery is not designed to make Helios64 as portable device that can be used without AC power line, but designed as backup power to perform graceful shutdown or hibernate in case of loss of AC power line.
Therefore it is normal if Helios64 turned on for a while when you press power button without AC power line.
