NimH battery care and feeding has occupied too much of my life in recent years. :-) It is significantly better for NimH batteries NOT to discharge them fully before recharging them. NimH life can be enhanced substantially by never discharging them fully on any occasion. Even when using multiple sets during a day's shooting, if you can manage to leave the ...

Do NOT do this. Please read this post from Electrical Engineering SE regarding Li-Ion battery. Li-Ion have one failure mode. Fire. And it's not a normal, lighter fire, or even a stove fire. It is a fire-that-burns-in-a-vacuum fire. It's a fire-that-reacts-with-water-and-air fire. Li-Ion is not the battery type to play around with. They are dead not ...

I don't know that there is a "best course of action", but here's what I do... I have multiple batteries, and I numbered them. When battery #1 gets low, I put in battery #2 and charge #1. If they've been sitting for a while, then the night before I'm going to spend enough time shooting that I may potentially need more than one, I'll top off the charge on the ...

No, this is safe as long as the battery is not in the charger. Some chargers may have a small power drain from being plugged in (even when not charging anything), but it shouldn't do any damage to the device to leave it plugged in.

The Nikon P330 camera uses a Nikon EN-EL12 1050 mAh battery. EN-EL12 battery capacity is nominally 1050 mAh as supplied. After market batteries may claim higher capacities and, regardless of label, may have lower capacities. If the charge rate is not limited by the camera itself when in-camera charging, or when externally charging the battery, maximum ...

You can buy dedicated accessories for charging all kinds of stuff, or you can spend a little more and get a car converter 12V -> 110V, or 220V, depending on what your chargers need. Then you can connect just about any standard device to it, as long as its current (wattage) requirements are not too high. Here is one similar to one I have and it came in ...

The Bower XC-CE6 3-in-1 Individual Battery Charger for Canon LP-E6 description at amazon.com says it can charge your LP-E6 batteries via USB. I've never used one.

What you're doing now is fine. Li-ion does not need to be fully charged for storage. In fact, the best state to store them in is between 30-70% charge, but I'd probably only bother with that if storing them for many months. It's also fine (encouraged, even) to recharge them when they're only partially discharged -- a very deep charge/discharge will ...

In Europe the voltage is 230v, so if your adapter operates outside the 220-240v range you have to buy some kind of adapter doing the conversion. Also, Italy, France, Switzerland and Austria all have different power outlet shapes, but there is a common plug called "Europlug" which works on all four countries ( http://en.wikipedia.org/wiki/Europlug ). Get an ...

Yes, this charger will work. You can see from the specifications in the picture that it will accept a range of voltage from 100 to 240V. That includes Japan on the lowest side, and the US / North America at 110, and Europe at 230V. You will just need a physical plug adapter, which you can get pretty much anywhere. The countries you are visiting all have ...

If you want an official Canon accessory, you can use the CB-570 Car Battery Cable. It works with the CG-570 Battery Charger and is listed on the accessories page for the 50d. As others mentioned, a power inverter is also a more general solution, though converting from DC to AC back to DC will use additional power and put additional strain on your ...

What you are looking for is the "Canon ACK-E10 AC Adapter Kit" which does not charge your camera but instead allows it to run off of AC power. But keep in mind that the 1100D/Rebel T3 is only going to allow you to record 17 to 29 minutes of video at a time. You will have to stop and start a new recording every 17 to 29 minutes depending on the settings you ...

A CSC, or (more commonly) mirrorless camera is actually quite a bit NOT "like a point and shoot, only larger." You really want to do a bit more research, as these cameras are significantly more expensive to own than a fixed-lens compact because of the interchangeable lens mount, which means that the "camera" (body) is really only half the camera. The other ...

Is there a way to charge a battery while still in the camera? Yes, it's definitely doable. It carries some risk but it's something I'd happily do if required. [My day job is an EE with much involvement with batteries and charging - having somebody who knows their stuff help on this would be "a good idea"[tm] Some cameras have DC input for a remote power ...

According to this: You charge the battery in the camera using a small square adapter with a folding plug that connects to the included USB cable. That means you can charge the battery from your laptop's USB port, but it also means you can't shoot while your battery is charging. You have to charge it in the camera.

It wouldn't harm the charger, but it is a good practice to turn off the switch and save power.

Suitability varies with camera facilities and with quality of the charger, but in many cases you will have no problems doing this. Usually a special adaptor will be needed but, in this case, it is probably a matter of "plug in and go". The EX-1 camera has an unusual feature - it will accept charging input from a 5 Volt "USB" power source and charge the ...

From what I can see the charger has the two pin plug, so that is compatible with the europlug used in most european countries, including all the ones you listed. You might stumble on an older socket installation for example in Italy, but they have the same current so you only need a converter for those. Modern sockets are compatible with both older and ...

No, it will not charge the battery. USB Voltage is 5V and the camera battery is ~7.4. They would have had to include a buck boost converter and other circuity in the camera just to allow for USB charging. However, the D90 does have the DC IN jack on the side. In the future, you'd be able to use an EH-5a AC Adapter to power/charge your camera. Of ...

According to Page 35 of the manual, the battery can only be charged in the charger, not in the camera. (note: the linked manual says DSCT70.pdf in the link, but the manual covers 3 versions including the T200).

As far as power drain is concerned, yes it will drain power. Will it harm your device has many other factors to it. Current will flow through transformer circuit. If you consider that as a factor that might harm your device, then it will. Giving complete technical details will be a little difficult here, but i'll try to explain with links to detail. A ...

No sadly it isn't. I had a 40D and sold it when I upgraded it to the 60D. Strange how it still doesn't feel like an upgrade lol :)

I'm guessing your battery is just old. It's a lithium battery, and lithium batteries inherently lose capacity with age. The D7000 was released some six years ago, so 75% is actually not horrible. You're still getting 700 shots with it, so you could either just live with it, or pick up a replacement. This battery, the EN-EL15, is still used on current model, ...

From what I see, not on a regular basis. Once in a while the batteries must be cycled completely, but otherwise no. Cell Phone Battery Care

This comment applies to camera Lithium Ion batteries in general. Based on personal experience, clone batteries CAN be about as good as a genuine one, but may not be. Weight should be similar. Low weight is definitely fake but correct weight may be fake too. Capacity should be as good as claimed from new. This is not trivial to determine but also not ...

One thing that stood out about the lp-e8 battery for me was the feel. Compared to an lp-e6, the surface is actually textured, almost a little rough, instead of the usual smooth feel. I can say from that image, that the battery charger does look different than what I have. Also, compare with the product in the official store. Battery Charger

I imagine any electric component has a certain life span. When the charger is plugged in, even without battery, there's still some current flowing and some heat generating. However, the current and heat are minimal on stand by. So, I would answer: technically - yes, it is harming the charger, but practically - no, it isn't. The charger will eventually break ...

You wouldn't want to charge the battery while it's in the camera, unless the camera is actually built to handle the charging itself. When charging the battery you use a higher voltage than the battery puts out, so that could fry your camera. Having the camera turned off doesn't help either, as that doesn't break the contact with the battery. The camera ...

Obviously it's a little easier if you can get a USB charger, but no worries- this is still pretty easy. What you are looking for is a "power pack". These are accessory batteries with USB and/or inverters built in. They are generally designed to charge a laptop on the go, so running small(er) battery chargers is even easier. Here's an older model on Amazon ...
