Photo Forum / Digital Photography / Digital Photo / October 2005Lithium AA batteries vs CRV3's
Which lasts longer on the shelf and/or in the camera? I'm not talking about rechargeables here. These are both throw-away type batteries. TIA  SignatureJoey Goldstein http://www.joeygoldstein.com joegold AT sympatico DOT ca >Which lasts longer on the shelf and/or in the camera? > >I'm not talking about rechargeables here. These are both throw-away type batteries. On the shelf I would think because some camera continuously draws power to maintain settings even when it's off. So batteries inside the camera will go dead eventually while batteries outside and sitting unused would retain its charge for a long time.

Even if above is true, that current is so small that such ideal battery would last 100 years. Note that some models (like Canon S2) have additional button cell for retaining data purpose and such cell lasts several years. So, draining is entirely dependant on battery type and alkaline or Lithium ordinary batteries have very long shelf life. Note that on Duracell ones is date od duration stamped and it's typically several years from date of purchase.However, Lithium cells have way bigger capacity than AA ones, no doubt about that. So, you should decide on how long of active usage instead of shelf life, since camera will probably be dead or obsolete before batteries will be dead if left unused. NiMH cells are discharged after couple of months, while Lithium rechargeables retain capacity for a longer time. >Even if above is true, that current is so small that such ideal battery >would last 100 years.

Some camera don't drain much but other camera tended to be power guzzler. I used to have Kodak DX6340 and if I left the battery in the camera then after about a week it goes down by as much as 25%. It's always been like that. YMMV SignatureWhen you hear the toilet flush, and hear the words "uh oh", it's already too late. - by anonymous Mother in Austin, TX To reply, replace digi.mon with phreaker.net > >Which lasts longer on the shelf and/or in the camera? > > [quoted text clipped - 8 lines] > too late. - by anonymous Mother in Austin, TX > To reply, replace digi.mon with phreaker.net Well thanks for responding, but that's not what I'm asking. Which one will let me take more pictures (once they're installed in the camera), the CRV3 or 2 Lithium AA's? Which one will last longer on the shelf?

CR3V, sure. But, they are more expensive... > Which one will last longer on the shelf? Who knows...but there's not really any big difference here. > > Which one will let me take more pictures (once they're installed in > > the camera), the CRV3 or 2 Lithium AA's? > > CR3V, sure. But, they are more expensive... OK. Thanks. The price I just paid for 4 lithium AA's was pretty close to the price I paid for 2 CVR3's, as I recall.
