If you're in the US and can stomach Wall Mart Eveready 357, 1/2 the price of the MS76 and still Silver oxide. At 01:30 PM 6/2/03 -0700, you wrote: Hmm, A76? Wouldn't that be an alkaline? Wouldn't that have the "dreaded" slow voltage drop discharge characteristic? I would have thought (from what I was reading online) that my choices were two MS76 or one CR1/3N (aka DL-1)? According to the manual, LR44 & G13 can be used. They are identical to A76 & S76. Two S76 are expensive so I use A76. Since the batteries power the meter only, alkaline should do the job. regards, Alan Chan _ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=features/junkmail Outside of a dog, a book is man's best friend.

Perfect fit, got a pair in two MX's and a LX. They're a listed substitute on most battery guides.

The PDML is definitely alive and well. Feign ignorance to post a question then argue with the people that offer answers. Isn't that a form of trolling? Len --- _ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus

I have to say that I used the Dl-1 batteries only once in my MX. Soon after that the light meter had to be replaced by the Pentax service. I can't say for sure that it was the the lithium battery that caused the failure of the light meter but it is probable. Enjoy, Alexander __ Do you Yahoo!? Yahoo!

Re: MX Batteries: MS76 vs. DL-1 (vs. ?)
Just a brief adendum regarding what I found as relative life expectancies beween 2 S76 batteries and a single DL 1/3n. My experience was based on use in a Nikon F2s Photomic, which used 2 rather bright LEDs for metering. The lithium battery gave about 20 minutes of metering, the silver oxides gave about 1/2 hour of meter on time. I have not bothered to do any sort of testing since, so my information should be considered quite dated. William Robb

Below are extracts from previous answers which I've posted to the PDML over the last 5 years (yes the question does come up regularly): "2 stacked LR44/SR44 are equivalenmt to 1 CR1/3N. The only reason that the CR1/3N cells may not appear in the compatible battery list in manuals is that they are a relatively late battery design" "The biggest problem with using the CR1/3N cells in the LX is that once you see the low warning battery it's all over in a few minutes, I always keep one or two in each camera case. I have used them successfully for years in LX, ME Super, MX, KM, SuperA, ProgramA, M6 and M6 TTL cameras (and probably more that I can't think of at the moment)" "There is no good reason not to use CR1/3N lithium cells in place of 2 x S76 or equivalents, these batteries are only ever used for metering circuits which have an inherently high internal resistance (read low current requirement) so are self limiting. Since the terminal voltage remains the same there is no real argument not to use them." ""I did a little research and found the following: Approximate self discharge rates: Alkaline batteries : 5 % / year (PX28A, A544, 4LR44 105mAh capacity) Silver oxide : 5% / year (PX28, 544, 4SR44 160mAh capacity) Lithium batteries : 1% to 2% / year (PX28L, L544 160mAh capacity) >From the data above we can surmise that for low current applications the Silver oxide and lithium cells should offer similar operational life over the short term (eg under 6 months) however the Lithium cells will allow longer storage period."

Could it be that the LX and P50/P30 draw too much current and overheat the battery, causing it to crack open and leak? But I would think the Super and Program A models would draw a lot of current as well. Maybe it is a physical size issue, like the CR1/3N is _slightly_ taller then two MS76s and in the "failure types" this damages the battery compartment, requiring an overhaul? Any Japanese readers/translators out there that can interpret the page any better? Thanks for the info Alan! - THaller

Hi Herb, > "that's what is recommended in the manual, S76 batteries. > hard to argue with that." > Thanks Herb! I guess I forgot that. I was reading all over the web about "the Pentax battery replacement issue" but I was know now reading about other Pentax models, like the Spotmatic, without realizing it. Got myself confused! :-) I still like the CR1/3N or DL-1, though. I do available light shots a lot, when it's fairly dark, and I can remember at least one occasion when I had to change the batteries and one of the two button cells turned over as I was loading them. Took a while to figure out what was wrong! Harder to do with the single CR1/3N! And that shelf life! Thanks for the response! - THaller

that's what is recommended in the manual, S76 batteries. hard to argue with that.

Re: MX Batteries: MS76 vs. DL-1 (vs. ?)
AFAIK MXs use normal 1.5V batteries. They weren't desinged for mercury batteries. Regards, Lukasz === www.fotopolis.pl [EMAIL PROTECTED] === internetowy magazyn o fotografii
