How to add battery to keep rtc time

If I power off the bananapi, the rtc time will lose. So, when re-power on the system, the time is old. So, is there any method to add battery to keep the rtc time.
Thanks. |

RPi also have the same problem. I heard the founder of Raspberry Pi Foundation, Eben Upton, said the major issue is to add a RTC battery onto RPi is unbelievable expensive. For low cost single board computer and target educational charity, personally I think this is not a critical issue here. |

In addition, I saw there is a space for battery on Banana Pi board. (BAT for external battery, BAT1 for RTC battery). Maybe someone could try to wire out a RTC backup battery manually.  |

I need to know the PN for the BAT1 connector, or else, it easy to break the board. |

Does someone has an idea on how to use these BAT connectors ? |

BAT1 is for RTC; BAT is for external battery. You can check the mark of "+" on the board. |

Cant you make a software fix that grabs time from someplace and updates it onboard? Seems cheaper and easier than adding a battery. |

of course, use ntp, however, if no network, how to solve it? |
