kevin_krumwiede2 Posted October 16, 2006 Share Posted October 16, 2006 In Philip Greenspun's article <a href="http://www.photo.net/equipment/best-digital-camera/">The Best Digital Cameras</a>, he says of the Canon A6xx series: "They use four AA batteries, which are heavy and will last for only 50 pictures." <p>Is this an exaggeration? If not, why has the power consumption gone up so much? I have an A520, which only uses two AAs. I've shot over 500 photos on a set of lithiums (never using flash) and well over a hundred on cheap alkalines. Link to comment Share on other sites More sharing options...
mr._smith Posted October 16, 2006 Share Posted October 16, 2006 This applies to non-rechargeable batteries only. Rechargeable batteries on a Powershot A630 or A640 (2300 Ni-Mh) should give you at least 300 shots and up to 500 shots. Link to comment Share on other sites More sharing options...
keith_van_hulle1 Posted October 16, 2006 Share Posted October 16, 2006 Agreed with the previous poster. I get ~350 per set of rechargables. Maybe more but I change about then anyway just in case. Link to comment Share on other sites More sharing options...
phule Posted October 16, 2006 Share Posted October 16, 2006 AA is a battery size not a battery type. 50 shots are from Alkaline AA's which were never designed for high-drain devices. Phil should clarify which batteries he's talking about. Link to comment Share on other sites More sharing options...
kevin_krumwiede2 Posted October 16, 2006 Author Share Posted October 16, 2006 Rob, That still doesn't make sense. How can the A620 only get 50 shots from four alkaline AAs when my A520 gets 150 from two? I can't believe Canon took that big a step backwards.

phule Posted October 16, 2006 Share Posted October 16, 2006 Kevin, 150 with the alkalines supplied by Canon or with others? I doubt Canon's supplied batteries are very good by even alkaline standards. The A640 also has a 2.5" screen whereas the A520 has a 1.8" screen. That should account for some of the additional drain. I don't believe Phil's figures, but does it really matter? Alkalines are for emergency use. You already know to use either Lithiums or NiMHs.

ulrich_michel Posted October 17, 2006 Share Posted October 17, 2006 Occasionally I use 4 Duracell alcaline batterys in my A620 and I find them to be as capable as rechargeble NM HD. Usually in exess of 250 pictures with LCD on and occasional flash use. In fact I find alcalines dont suffer from the dissapearing power sindrom after one Month like rechargebles. and the initial Voltage is higher to boot.

wilsontsoi Posted October 17, 2006 Share Posted October 17, 2006 4 rechargeable NiMH AAs are what I recommend and have been using on my <a href="http://www.photo.net/photodb/presentation?presentation_id=317651">Canon A620</a> and I've certainly been getting more than 50 pictures from that set of 4 NiMH AAs. The newer A640's larger LCD may draw more power, but I'd bet it will definitely take more than 50 photos per charge! Link to comment Share on other sites More sharing options...
