Each battery-chemical system has its benefits and drawbacks. As all the A-models regulate their feed-voltage, we can use any 1.5V system. One thus may choose on other preferences.The silver oxide versions last a lot longer.
The A-1 was around and current before lithium batteries, so I have no knowledge about whether the lithium version of the battery is appropriate.
Hello - does anyone know which battery the Canon A-1 takes? I've searched around and have been getting conflicting answers. I dug out my old Canon A-1 but it doesn't have a battery. I seem to remember LR44, but I cannot locate that battery these days. There are lists of alternatives, but I don't want to order something that won't fit.
Any help would be appreciated,
John D.
That is good to know..especially for the OP.Each battery-chemical system has its benefits and drawbacks. As all the A-models regulate their feed-voltage, we can use any 1.5V system. One thus may choose on other preferences.
That can't be right. Alkaline is known for its good self-discharge properties, but it CANNOT source a high current. Lithium, on the other hand, delivers high currents with ease, and also tends to hold charge quite well - hence it's prevalence.My understanding was the current load (milliAmps) was the determinant, and the lithium could not deliver as much as the other two chemistries.
I am not sure if Most/Any manuals even make mention of [voltage stabilisation]
My recollection is that the Bronica dis-recommendation of lithium at the time it happened was relatively early in the history of lithium batteries and there were purportedly many variations in the 6 volt batteries from different sources. As such there were concerns about some versions being unreliable. I've never tried the lithiums, but for both my SQ-A -- and my Canon A-1 & AE-1, the alkaline versions available for the dog collars seem to work OK. Ace Hardware carried them last I looked.That can't be right. Alkaline is known for its good self-discharge properties, but it CANNOT source a high current.

"Lithium cells can be engineered for high amp draw, and lower shelf life; or low amp draw, but longer shelf life. They have the potential for the highest energy density per volume of any low cost cell, but the trade off has been made, in "consumer" applications, for long shelf life. This allows these cells to be terrific for hearing aids, and pacemakers....but poor for an intermittent high amp draw requirement."
Thanks -- I think I have a copy of that that "somewhere" here, but I didn't find it in a quick look through my "file system." At any rate it appears my recall was fairly good.One post not only had a link to a now non-existent Tamron web page, but fortuitously had copied the text posted there!
