Canon A570IS, 200 shots on eneloop, 10 shots on Alkaline
Chris Malcolm wrote:
In my Canon Powershot AA-using A300 I only get about a dozen shots on a cold day. But after putting the batteries in a warm pocket for five minutes I'll get several more. And so on. If I'm shooting in the cold I'll usually keep rotating three sets through the camera and a warm pocket to keep the thing going. I don't think it was too cold on this cruise. It was San Francisco, Ketchikan, Juneau, Skagway, Tracy Arm Fjord, Victoria, San Francisco in late June/early July. I've been much further north in Alaska, earlier in June, and the weather was pretty mild. |

Some cameras have brief high peak surge current demands which are uncomfortably close to the maximum the cheaper alkaline AAs can deliver. That's why lower nominal capacity reachargeables can last so much longer than nominally much higher capacity alkalines in some cameras. I've bought some cheap alkaline AAs on the run which only lasted a dozen or so shots even in summer sun. -- Chris Malcolm DoD #205 IPAB, Informatics, JCMB, King's Buildings, Edinburgh, EH9 3JZ, UK [http://www.dai.ed.ac.uk/homes/cam/] |

I guess it's possible that the cruise line was selling some no-name AA batteries, but I doubt it. |

My old sony is the same, with alkaline in winter I got a few shots, with nimh I go forever it seems. Now i use eneloop since my NiMh are very old, its great having a charged camera now! Okay, so it seems to be a consensus that getting very few shots on alkalines is pretty normal on newer models. I should have insisted that my sister-in-law take a charger and some NiMH cells. I've been spoiled by not having to deal with AA batteries for a while. I bought the A570 IS because the spousal unit wanted a larger camera than the sub-compact pocket cameras (which all use Li-Ion), and the AA batteries were a compromise I was willing to make in light of the Sanyo eneloops and other low-discharge NiMH batteries. I've added some stuff to the web site about this. Unrelated, I've added a longer evaluation of the Tenergy T6278 Universal (AAA, AA, C, D, 9V) Smart Charger, I've expanded the section on solar charging, and fixed some of the dead links.

Okay, so it seems to be a consensus that getting very few shots on alkalines is pretty normal on newer models. It's the same old story with you, isn't it? You'll blindly accept whatever anecdotal report supports your bias. Why don't you test your A570 IS when you get it back? Getting fewer shots on new camera models using alkalines is *not* pretty normal. My Fuji is good for 300 shots using the CIPA test where 1/2 of the shots use the flash at full power, and with the LCD display turned on. The previous version of this camera was only good for 250 shots. Your own A570 IS is rated by Canon as being good for 120 shots using alkalines with the same stringent CIPA test, and 400 shots per set of alkaline batteries with the more lenient non-CIPA test where the viewfinder is used instead of the LCD display. The previous version lacking IS (A530/A540) was only good for 90 and 360 shots, respectively. You and I both know that with a fresh pair of alkaline AA cells and the mild weather your relative used your A570 IS in, it will be good for far more than 10 shots, even if you forget to disable the flash. But that won't stop you from trying to mislead gullible visitors to your "battery information" website. BTW, Canon reports that with the latest version (the A590 IS) the number of "CIPA" shots using the flash and LCD display increases from the previous 90/120 to 200 shots. So much for your theory that newer cameras get fewer shots from their batteries. You once again have demonstrated your fanatical battery bias and lack of integrity. |

Thats what happens when you lend a camera to someone who makes no effort to understand the camera fully. With flash? what was the temperature, with IS on, autofocus, Lcd, alot of reviewing, and someone who doesnt know how to use a camera, who knows. Someone who thinks can use settings that dont drain batteries as fast. What brand and age were the batteries, I recently bought old ones that were not very good. Alkaline to me dont work well. Well the whole point of a point at shoot is that you should be able to use it _without_ having to understand it fully. I don't care what the settings are, 10 photos on a set of batteries, even with flash, even with reviewing the photos is unacceptable. Including a set of alkaline AA batteries may be seen as a good idea by the manufacturer, but I think it really gives the wrong impression of their product to the consumer that isn't familiar with all the issues of different kinds of batteries. I didn't realize just how bad the situation is with alkaline batteries until I saw all the responses to the original post. I looked on the Canon web site and they say 120 shots on a set of alkaline batteries, but they don't say the conditions used. |

Yes, assuming that one (such as your relative) isn't a total nitwit. If the AA batteries were unused when placed in the camera, getting only 10 shots may be because they weren't alkaline batteries. Using standard, or "heavy duty" batteries could result in only 10 shots. That you automatically assume that your camera might be good for only 10 shots per set of alkalines indicates that either nitwit genes run in your family, or that you're still at it, trying to dishonestly mislead gullible people into thinking that cameras won't perform well if they use AA batteries.

I looked on the Canon web site and they say 120 shots on a set of alkaline batteries, but they don't say the conditions used. Nitwit or spinmeister? The information is in your manual. Using alkaline batteries the A570 IS is good for 120 shots using the CIPA test procedure, and approximately 400 shots for flashless shots using the viewfinder. Once again, the self proclaimed battery expert has to resort to pretending to be dull witted and ignorant in order to make it appear that AA batteries aren't up to the job. BTW, once again you appear to be either a complete nitwit or are blatantly lying when you claim that "they don't say the conditions used". Have you any idea what "CIPA" means? Quoting from the Specifications Tab on Canon's A570 IS web page : Shooting Capacity Still Image: approx. 120 shots (AA-size Alkaline Battery), approx. 400 shots (AA-size NiMH Battery)* Playback Time Approx. 540 min. (AA-size Alkaline Battery), approx. 660 min. (AA-size NiMH Battery)* * LCD screen on. The above figures comply with CIPA testing standards and apply when fully-charged batteries are used. http://www.usa.canon.com/consumer/co...elTechSpecsAct |

I've bought some cheap alkaline AAs on the run which only lasted a dozen or so shots even in summer sun. I saw on the Delkin web site at "http://www.delkin.com/pdf/product_docs/rcr_v3.pdf" their comparisons between AA alkaline, AA NiMH, and the RCRV3 that they sell. Of course they're trying to sell the RCRV3 packs, so maybe they aren't credible (and the self-discharge they show is pre-eneloop), but everyone that's responded to my original post said the same thing about alkaline batteries (in fact Delkin shows more shots on alkalines than anyone seems to have gotten with alkalines). I don't think the RCRV3 will work in the A570 though. |

Now the typical review says something like "The alkalines that come in the box will quickly find their way into the trash." edited for brevity You obviously shoot the same way that your relative does, where "no effort was made to turn off the flash". Hello, ASAAR: Electronic flash can genuinely clobber batteries, of any type; even my Kodak P850's KLIC-5001 (proprietary Li-Ion pack) absorbs a severe beating, from the camera's xenon tube and its big capacitor. Hence, I "shutter" to think how poor, helpless alkaline cells would fare! :-J Cordially, John Turco |

Hello, ASAAR: Hey, quit being so damned disrespectful! Steven M. Sharf includes this modest tag line, along with his newsgroup articles: "Earth's Independent Source for Digital Camera Battery Information" Now, just who are you, to doubt Herr Battery Meister's vast knowledge and impeccable honor? Furthermore, although there may well be other planets in the universe, populated by beings whose wisdom rivals that of SMS, himself...it's highly questionable whether any of these hypothetical creatures, could ever hope to match his divine grasp of all battery-related matters.
