<p>It's been a while. I am still using my D700/ MB-10 combo. The question is not about IQ or technique but about what started recently with my system.<br>
I was using the D700/ MB-10/ EN-EL4a (all Nikon genuine) for a while and quite happy. although I can spend my time for this hobby less and less, so it is sometimes weeks between the use. One day, I charged EL4a fully and put it in MB-10 - then the LED on top of the body shows "Law Battery (the shape of the battery with thin black area - please imagine)" and when I turned it on, it just blinks and nothing works.<br>
Well, I then detached it and used the fully charged EL3e (the small guy) and put it in D700. It works. Hmnn. Then I put that perfectly fine fully charged same EL3e into the "EL3e adaptor" that came with MB-10 and attached it to D700 body. Again, same "Low Battery".<br>
So, so far, I have concluded (1) doesn't seem to be battery problem, or even charger problem, (2) then the MB-10 fault, maybe.<br>
To eliminate possibilities one by one, I borrowed another MB-10, which is perfectly working with his D300, and did the same thing as above. Nope. The same result. Okay, then my conclusion (3) this is not MB-10 fault.<br>
Then, the rest is D700 body problem. I cleaned the terminals with alcohol/ Q-tip. No change.<br>
Okay, so I brought the set to the service center - they checked all and said "battery has deteriorated". REALLY? Last time I checked, it had no deterioration (like I said, I don't spend a lot of time with this camera). But I bought a brand new EL4a from Amazon and charged it and tried again. THE SAME THING!<br>
I am a bit frustrated. Is it time to re-visit the service center?<br>
I would appreciate any help you guys can provide. Thank you.<br>
