No, I meant the main = Li-Ion:
Originally posted by photogem .....@stevebrot: The AC adapters won't charge the main (Li-Ion) battery, so I question it will charge the CMOS.
The CMOS
might be charged when the camera is switched on. I never tested that.
The Li-Ion can only be charged with the external charger which makes sense because hardly anybody uses the AC-Adapter. If the AC-Adapter could
charge the Li-Ion, the Pentax would be larger and heavier, nobody wants that really.
Originally posted by stevebrot I suspect the only way to know for sure might be with a patent search where these things are spelled out using state diagrams.
Indeed!

Here (again!) the spec-sheet:
MS414GE | Seiko Instruments Inc. Micro Energy Division Originally posted by alfa75ts The internal batteries in both my K7 and K3 still work as intended.
But this answer of yours does not indicated "work as intended:
Originally posted by alfa75ts I have left the camera (K7, K3) without a battery overnight hundreds of times without a problem. I have left it longer than that once or twice and had to reset the clock but the internal battery recharged after putting a charged battery in (the internal battery may not have been completely flat).
I'd say this is not really intended. IMO it is a pain having to reset ones settings.
Originally posted by alfa75ts I never said it did! I said you do not need to have the camera on an AC adapter while charging the (main) battery overnight. However I suspect you're wrong as the charging circuit for the internal battery is on the main board which is powered by the AC adapter. But I haven't tested it so I will not say it charges.
Do you actually have that AC-Adapter?
As I answered to Steve, I guess the AC-Adapter "might charge" the CMOS when the camera is on, but that was not your nor my point.
My only point was, that the AC-Adapter does NOT CHARGE THE MAIN BATTERY (Li-Ion). Nothing else.
Hardly anybody uses the AC-Adapter.
As much as the main li-ion is not charged, as much the CMOS won't be charged
if you have the camera switched off without a Li-Ion inside (or Eneloop etc. if another Pentax body).
If you have the Li-Ion inside, it charges the CMOS even if the camera is switched off!
Thats the whole point! Nothing else.
All the rest is useless and misleading. This is not about who argues better or wins some silly arguing race!
This is about verifying and giving Pentax-users the correct information!
That is why I started this thread
before this one here started:
Maintainance of CMOS or memory or backup-battery - PentaxForums.com
And funny enough quite soon a person has exactly that problem.
In this thread you also can read the correct specs of the MS414 which you were so sure:
Originally posted by alfa75ts Pretty sure the spec sheet I saw said 100 but maybe not.
while right in front of your nose there are the specs with a clear 50x!!!
May I suggest we leave it with this?
The TO had important questions and maybe can recharge the CMOS with some luck, if not it possibly is too expensive to get it repaired.
