Is there any harm in leaving the battery in the charger when not in use? Other than forgetting it's not in the camera and going off to shoot something?

Can't tell you why, but they recommend taking batteries out of the charger as soon as charging is complete. They also recommend storing with a 40% charge. The latter, I've never done.

Now you're all set. Get out and shoot!

Some chargers might really never shut off. I remove the battery and unplug the chargers.

Haha, my chargers don't stop at 40%, and why would I drain ≈60% after charging??? and how???
So if the battery is half dead, I'm going to store it and hope that I have time to charge it completely before I want to use it?
Not going to happen!

Sometimes you find weird stuff on the internet! Not something that seems logical. Though since they drain a bit when stored, I will check the spares before a trip or event.

There is no single general rule that encompasses every type of battery and every kind of charger. Since batteries are becoming more expensive and we depend so much on them, it pays off to research the proper charging and storage procedures for all your important camera and flash equipment batteries.

I don't usually listen to all the old wives' tales and mythology on the Internet. I go directly to the manufacturer for the correct information. It's not that folks are out there to fool anyone but some are espousing procedures applied to old Nickel Cadmium rechargeable batteries that no longer apply to someof the later versions and the newfangled Lithium-Ion batteries.

The technology in the ENERGY STORAGE industry is growing, improving and innovating at a rapid pace. That's what it's important to verify charging procedures with information from the source.

The same thing applies to chargers. Many years ago, I built my own chargers that automatically switch to trickle charge once the battery attained fill capacity. Those chargers had enough circuitry to fill a case the size of a shoebox. Nowadays, with advances in miniaturization, in some modes, that circuitry can be encased in the small plug-in charger, complete with LED indicator lights. Frankly speaking, I don't know if that procedure is applicable to the latest Lithium-Ion cells. It worked well with older batteries in that the batteries were always ready to use regardless of the storage time. I use the chargers that came withte the original equipment.

Honestly, I don't know if leaving the batteries connected to the charger once they are fully charged will cause any issues. I have never tested to see if the charger somehow drains off some of the power if left connected.

I have no experience with the long-term storage of any of my batteries because they are seldom left in a dormant state. They are in use being rotateed in and out of the equipment and charged regularly.

I prefer to remove them as soon as charging is complete or I would not remember if it needed charging or was done charging.

For any rifle shooters out there, I clean and reuse the bullet boxes for battery storage and transport - e.g., Sierra, Berger or Speer .30 cal are great. These keep the AA batteries aligned and prevent any contact with terminals. smaller calibers are useful for AAA. Plastic .22LR boxes for camera batteries.

I recently bought a portable radio.CD player. It plugs in, but it can also operate on batteries - 8 D cells!

I once bought a shoe-boxed size charging station that would charge everything from AAA to D in multiples.

Not only would it charge rechargeable batteries, but alkaline batteries as well. It would charge those slowly for a while and then stop. Then it would start again (rinse, lather, repeat).

I never tried it with alkalines.

Alkalines, like carbon-zinc, are not really designed to be recharged. Might work a bit, but not reliably.

My OLD boom box (radio, CD, cassette) only used six D cells, but plugs in also.

Two differant chargers two sets of batteries for two differant cameras, then add in two differant smart phones and one tablet. At home it's very difficult to locate outlets enough to charge everything all at once. But while in the van, Our Anker charger works wonders. if you need one for the car or a portable charger look into the Anker products. In a pinch, I'll grab my Anker power pod mini which is about the size of a lipstick container and I can attach to the camera for a quick power up while on a shoot.
