Battery for MD4

Hello,

I think that inlcuding an internal battery would be interesting in order to maintain RTC values.

Thanks.

Hello Raúl,

Are you using an MD4 build during 2014?
The first IQAN-MD4:s had a quite short RTC backup time, about 4 hours.
I am not sure if you saw this, but on MD4:s built 2015 the RTC backup time has been increased to 14 days.



There is still no battery inside, but a RTC with lower current consumption than the first MD4:s. This is supplied with a capacitor inside the MD4. It gets charged either if you connect +BAT or +RTC.
Thanks Gustav,

Sorry I was talking about my experience deploying old MD4(2014). I haven´t tested new ones yet but in 2014 vers I have lost RTC backup time just disconnecting +Bat and +RTC.

Thanks for Appendix info I will test that.
