One of the easiest choices is to buy brand name batteries. From batch to batch the manufacturer takes quality and performance very seriously. You know and I know that in general there will be no lemons. Generic batteries can be made by any number of manufacturers and they all take on the challenge with different perspectives. And as a result if you were to ...

1. Use high-quality NiMH cells You want the NiMH chemistry because it's able to supply the high peak current that leads to faster recycle times (and less energy lost to internal resistance). "Hold their charge when not in use" and "long lasting (on a single charge)" are opposing criteria: the reason is that the newer low-self-discharge (or "hybrid") cells ...

Leaving the batteries in your camera for a week or two between uses will be no problem. If you plan to leave your camera unused for six months to a year, you might want to take them out. And, the lithium battery pack used in your camera (like most current dSLRs) should hold its charge on the shelf fairly well, so you won't have to worry too much about it ...

I agree Sanyo Eneloop are very good batteries, but you should also consider getting a high quality charger if you want your batteries to last a while. I took the recommendation from this Coding Horror blog post and went for the BC900, but the newer BL700 is highly recommended as well (comparison here).

Amazon has the LP-E5 for $39.99 USD. To me, after buying a $500+ camera, a $40 second battery is a no brainer. I still have the original BP-511a that I purchased for $70 from Canon for my 20D in 2005 (it's now in my 40D), and I purchased a second LP-E6 for $79 for my 5D Mark II. In nearly 5 years of shooting, I've spent a total of $149 for camera ...

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 ...

This will not be a problem. Milliamp-hours are a rating of the capacity of the battery (metaphorically, the size of the gas tank), and having extra won't cause any harm. (Basically, it's how long the power will last, not how strong it is.) It's possible but unlikely that cost-cutting in the battery may have other, more problematic issues, but many people use ...

I (and many others, from what I've ready), really love the Eneloop batteries by Sanyo. That's an Amazon link to an 8-pack but they're available elsewhere as well. I've had great results as far as the batteries remaining charged, recharging quickly, and offering good performance for things like flash cycle time.


12

Based on the reading of the battery spec, no. The battery pack supplies 7.4v, while USB can only supply 5v. However, you can buy the ACK-E2 wall power kit to power the camera directly from a standard outlet.

Not only do you need new batteries, but what you want is low self-discharge NiMHs. Like the name says, they have a better not-in-use retention of charge, reducing frustrations like this. They generally have lower capacity than "regular" NiMHs, but unless you're planning to recharge and then use them up immediately, it's worth it. The common brand name here ...

Usually, we buy more batteries. For pros, a few extra batteries is a very marginal business expense, and for serious enthusiasts, it's usually just worth it. I always want a spare battery for my DSLR, even though it has excellent battery life. If you're in the studio, an AC adapter may be an option — although even then, keeping the camera free of an extra ...

Yes! This is a normal problem with rechargeables, and there is a type of battery made to solve it — low-self discharge NiMH. These will hold a charge for months sitting idle. The downside is lower capacity, but I find that a small price to pay for actually being useful. The main brand is Sanyo Eneloop, but there are others, too.

It really depends on the model but modern cameras are very good at saving power during sleep mode. Sleep mode however on most cameras consumes some non-negligible amount of power, so if you wanted the more battery-life then turning it off is better. Even better than off is to remove the battery as some cameras, particularly Nikon DSLRs, use power even when ...

Nikon produces excellent manuals for their flashes, with a lot of great technical information (rivaled in this area only by Metz). The following is from the SB-600 User Manual, page 19: Alkaline-manganese | 3.5 sec. | 200 / 6-30 sec. Lithium | 4.0 sec. | 400 / 7.5-30 sec. Nickel | 2.5 sec. | 180 / 6-30 sec. NiCd (1000 mAh) | 2.9 ...

As noted by others, if you want a battery that is a straight replacement for rechargeable AA cells then LSD (low self discharge) NimH will meet your need. LSD cells have more, not less, lifetime cycles than standard cells. A first generation Sanyo Eneloop cell offers about 1000 cycles (compared to less than 500 for a standard NimH cell) and their new 2nd ...


10

Yes, they do. "Body only" means as opposed to in a kit with a lens. You should actually get a battery, matching charger (except in the now-rare case of cameras which use AA cells), an instruction manual and probably a CD with software, maybe some random cables, and various other little bits and pieces like a viewfinder cover. In fact, the manual will ...

All else being equal, yes. A bigger sensor requires more power. Advancement in power-saving technologies can sometimes improve that but with higher pixel counts being the norm, we do not see much of that. Each pixel requires circuitry so higher megapixels require more power than making the sensor bigger. Luckily bigger cameras have room for bigger ...

I had a super cheap non-Canon battery in my 400D and it was as good as the Canon one. But I wouldn't trust a sample of 1 if I were you ;) Although you mention in the details you have a 450D, I'll add an answer to the generic Canon question for others that may read this. For some Canon cameras (such as the 7D) the battery holds special information ...

Rechargeable Ni-Mh batteries have a lower voltage, and a higher current. This gives a faster recycle time. I use Sanyo Eneloop batteries, which claim to have a long shelf life. The claim is that they retain 85% of their charge over 12 months. I have no reason to doubt them, although I have only been using them for 6 months. update I have now been ...

If the batteries are multi-celled, then yes, full discharge is good, once every couple of months. There are sensors that combine readings from multiple cells to determine capacity and balance the cells to improve efficiency and overal capacity. Other than that, Li-Ion still prefers shallow discharges. To maximize Li-Ion batteries' life, store them in cold ...

(from comments) Find the exact model here, and look for the specifications: http://www.canon.com/camera-museum/camera/film/series_eos.html Note that there are many different models that are called "Canon EOS Rebel something", and some of them use different kinds of batteries. For example, EOS Rebel XS seems to use CR123A batteries while EOS Rebel 2000 uses ...

When I am out shooting I always leave my Canon switched on, after 30 seconds or so it goes into sleep mode. I have never noticed any negative effect on battery life. Leaving it switched on means that it is ready to shoot as soon as I need it and I don't risk missing a photo opportunity. I will usually turn it off when I put the camera into my camera bag ...

If you're going to use the camera with regularity, you simply need an extra battery, in my opinion. You will, eventually, have a few days where you can't recharge for some reason so having the extra on-hand is important. You may forget to recharge, you may not be near electricity, you may have forgotten your charger, etc., and having an extra battery just ...

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 ...

Non-rechargeable Lithium batteries will definitely last longer than standard alkaline batteries... anywhere from 3x to 5x longer, depending on who you ask, and how it is measured. You will also get faster recycle times with non-rechargeable Lithium batteries as well. There are two important things to know about non-rechargeable Lithium batteries before you ...

I have conducted quite a lot of testing to find out how the low self-discharge cells keep their charge. You can see the results here. Sanyo claims the self-discharge pattern follows inverse S curve, meaning that you lose first some 10-20% rapidly in first 1-2 weeks or so, and then it levels, and the batteries retain some 70-75% of charge after one year. My ...

Buying more batteries is the easiest and simplest solution. I have 2 original manufacturer and 3 clone batteries for an A77 or A700. (See below re clone/original capacities etc) I find that there are very few days that that is not enough. For a wedding or all day event or similar I carry two chargers which can charge from mains or from a car lighter (or ...

The simplest and arguably most effective solution is just get more batteries. Another option that is available (for some cameras at least) is to get a Battery Grip which holds extra batteries and also provides a second grip for shooting portraits.

I never take my battery grip off my 5D mark iii. The extra battery life that it gives is wonderful. That said, I use it with the official batteries and I have a total of 4 regular batteries for it. I do still have a loaded and ready to go AA tray in-case of emergency, but AA's don't really work well as a battery option because they still provide less ...

I highly recommend Zeikos battery grips. I have the Zeikos grip for my 5D Mark II, and I could not be happier. It matches my 5D2 perfectly, with no flex. With two batteries, it gives it enough heft to match my bigger lenses. It has vertical shooting controls (which I never use), and sits firmly attached to my 5D2 body. I bought it from Amazon, paid $90.00, ...
