EN-EL3e batteries

My D90 with the MB-D80 fitted and two fully charged (well the charger light isn't blinking) are only showing up as being 97% charged. They are both Nikon batteries and not that old. Is this normal or should I leave them on the charger for longer?

Thanks

Not something ive ever looked at,i just charge until the charger says done,dont know what they read as.

Some batteries will not ever fully charge to the design specifications. I would't worry about it unless they discharge too quickly. What level of service life does it show that they have?

I've just had a look and I cannot see any mention of service life. Where would I find that?

Personally, I wouldn't worry about it; unless they're draining unusually fast. I actually have the opposite situation from you. I have a Nikon battery that never shows "charged" in the charger but comes up as 100% in the camera.

It doesn't take long for lithium batteries to start losing their max charge. In practical terms you probably won't notice that 3% difference.

I just recycled one that was down to ~70% at max, but it was also ~4 years old. Oddly enough, I have one that's a few months older that still recharges to above 90%. And I switch between them every charge, so they were both used about the same amount. This just shows they wear out at different rates.

Nikon D90 Battery Drain - During Video Only

Hello,

I am getting into VLogging and have the Rode Go External Mic for good audio quality.
I have the following cameras.
1. Nikon AW 130 – Point and Shoot, Weather Proof camera with Built-In-Mic.
a. No support for externa mic makes audio an issue.

2. Nikon D90 – DX Format camera – Provision to attach external mic
With LiveView on my battery drains in just 5 mins.
Lack of auto focus for video – requires me constantly adjust as per subject.
That defeats video for a Vlog set up

3. Nikon D810 – FX Format camera – Provision to attach external mic
Too big for a VLOG
I would rather use it purely for high end photography

I am particularly interested to know about D90 and D810 for the Vlog Set up
Why does a D90 battery drain this fast for video – is something wrong with my battery?
D90 for photoshoots works just fine, as I use manual focus and LiveView off. It lasts through the day.

I dont wish to invest in a new battery if its an inherent problem with the D90 while shooting videos.

Please advise.
Thank you so much.
