Battery calibration?

Though I think the output charge in a defibrillator comes from Capacitors (yes, those are commonly known to need conditioning) not the battery. So your analogy is better for a strobe than camera.
I respect paramedics, they've helped me several times. Though my relationship with a defibrillator is a bit more intimate, I have an implanted defibrillator. It of course works at the IC milli or micro volt and amp level.
Still thinking Nikon likes selling batteries. Do Canon, Sony, Pentax, Fuji, Panasonic, and Olympus cameras and chargers have battery cell monitors / calibrators?

I think a lot of people that have a lot of todays toys that require batteries don't really realize that a typical battery today comes out of a toy as a one piece battery in a plastic enclosure that is made up of multiple cells inside that plastic enclosure. I have a $125.00 battery in a radio controlled aircraft that is made up of 6 cells, and my charger cost $160.00. If all of those cells aren't putting out the same voltage during a flight then the battery can fail unexpected and I can suffer the loss of a $950.00 investment in that toy. Battery calibration is real and important. Suppose you are out taking pictures and just as you are about to capture an image that you have been seeking for a long time, and your camera battery suddenly indicates "dead" and your camera shuts down. If your battery had been calibrated your camera battery would have lasted longer and you might not have missed that great image capture.

Once again many demonstrate only typing skills and a few provide educated information.

How is this different from four 1.5v AA batteries (cells) in a device? One goes bad, you replace one or all four. Batteries are electro-chemical devices that essentially consume themselves over time. How do you fine tune them? Also there are random statistical differences between all manufactured things. One reason Mil Specs require failure rates and consumer products usually don't. I guess I might read up on these modern Li-Ion batteries that I use daily with no problems. Also the rated voltage for a battery differs from how it acts under load. Study the charging system in your car. Though this could work in favor of your argument, I'll admit that much. So what is the cause of composite battery failure from differences between cells? I certainly don't know and have given it little thought since as I said, the rechargeable batteries I have seem to all be fine.

Right up there with muffler bearings and dual chrome plated dip sticks!

That's the way it is. Common sense isn't common. The obvious answer isn't always right.

There's a calibration mode with high end Canon battery chargers. My 1DIV has that and according to what I've read, this can extend the life. The calibration mode also allows a more accurate reading when charging and replenishment in future incidences. I've only had to use it once in the last 5 years and it automatically went into the mode once the batteries were inserted into the charger.
Even modern cars now have have similar functions; in the BMW world its called battery registration. A small chip is included in the battery cable connectors and monitors battery health and charge rate.
I know so as I now have to code one engine management computer and tell it its a new battery after replacement so rate of charge will not be same as old battery.

Thanks to all the latest posts. It's good to find that this forum is not totally composed of belittlement & put-downs. The early posts were very discouraging.

In the nicad battery days, calibrating a battery had real value. It meant occasionally draining the battery completely, then charging it completely. Helped the battery to remember what its capacity is. Laptop computer makers recommended doing it.
NiMH and lithiums do not exhibit "memory" as such and don't need "calibrating".

That is what I had thought, but we might be wrong these days according to some of the replies here. We seem to have some UHH battery engineers! Or at least the battery conscience people, and why don't any of my products get so picky about load voltage?

be sure to buy OEM batteries I bought a name brand battery for my D3400 from my local camera store, where I bought the camera. it charged fine, but when placed in the camera a message appeared stating it was an unknown battery and incompatible. the dealer had never seen anything like tat before, refunded my purchase price and sold me a genuine Nikon replacement

No problem; just wondering because it is hard sometimes to follow comments when people don't click "quote reply" when posting replys. Have a good day and take many great photos.
