May I ask if-
a) the battery indicator behaved differently previously?
b) your shot count is now noticeably lower than before?
question a, the battery indicator has acted this way since I bought the camera. I've just dealt with it.
question b; yes, it's always been less than I expected from Eneloops.

Using the Sanyo charger, once batteries are fully charge, the green light/s are steady green not blinking as when charging. I assumed that meant the charger wasn't charging any more.

Anyway, thanks for the added info Vincent.

Ah, thanks for that -
so there has not been any big change in the indicator behavior for your eneloops (even with firmware updates).
Unfortunately the Pentax dSLR battery meter has pretty much always been an issue
(I don't think there has been any improvements to the meter behavior after firmware 1.01.00.05 )
- like you, I just deal with it.

Getting less than expected with eneloops -
you knew I was going to say -
of course depends on one's usage, and expectations (sorry)

However there may still be a small chance charging could be a contributing factor -
could you please tell us the model of the eneloop charger you are using?

Thanks,

If I could read it I would supply the model number. Old eyes don't see well and my magnifying glass isn't that great either. Model number NC-MONO6U, I think.

OK could that be MQN06U?

There's quite a nice thread:
Sanyo Eneloop Battery Chargers - Spec Sheets

google "MQN06 pdf" and there are a number of listings for the pdf manual -
from which:


Unfortunately this is one of those "marginal" eneloop chargers -
of course it "works" -
but it is very far from optimal -
the charge current is 300mA which is 0.15C way below the optimal 1/2C (1000mA) for eneloops,
also it has to charge in pairs - that can lead to an imbalance in the batteries as mentioned before.

I am not saying it is definitely the charger -
it is sub-optimal by quite a margin -
but you have to use your own judgment on this.

Here's a really good article:
An informal look at the Sanyo NC-MQN06U – charging in pairs

I have always used a charger that has independent channels, ie: can charge batteries one at a time,
and always charge at 1/2C - in the case of eneloops 1000mA.

The "best" commonly available consumer charger is the Maha/PowerEx C-9000
it can be found for just under $50 shipped from places like Amazon.

There are cheaper chargers that also can do independent charging and around 1000mA
Sony Cycle Energy BCG34HRE4KN
this is really good - and low priced at $28 shipped, it's a bargain
(search for coupon code and price is $23 shipped with tax!) -
especially as it comes with 4x Sony CycleEnergy (blue) - when last checked were confirmed re-badged eneloops.
[IMPORTANT NOTE: I bought one of these - the Sony CycleEnergy Blue are no longer re-badged eneloops - so not quite as good]
[pdf] Super Quick Charger - Sony eSupport
esupport.sony.com/docs/BCG34HRE.pdf

and possibly:
Soshine SC-C3 Intelligent Rapid Charger
$15.60 shipped but from Hong Kong and it is not UL listed.
JPG image of manual

Note both these cheaper chargers will do about 1/2C when charging 1 or 2 batteries only -
when charging 3 or 4 batteries the current is sub-optimal at about 1/4C
(again it will "work", but not that well, but at least they have independent charging channels)

Yes, it could be that model number. As I said, my magnifying glass isn't all that great.
I've always wanted a Maha/PowerEx C-9000 charger but couldn't afford it. The Sanyo has two channels, charging two at one time works fine, takes seven hours to charge all four. My Eneloops are 2000mAh.
