What battery do you use with the Pentax Spotmatic II?

[andrew_hall1]

I'm looking for the exact model/size for a modern battery to test an SP II

before selling and am not gonna get an adapter.

 

Sorry if you've seen this question before. I did a search and people just keep

saying 1.5 V silver oxide/hearing aid/alkaline or whatever is fine, which is

not that specific.

 

Thanks in advance!

Well go to your local camera shop and buy the appropriate Wien cell, or do a 10 second google search.

The google search returns tons of hits and the first link shows a Pentax Spotmatic II battery is a PX400. 5 min of reading shows that the meter is a bridge circuit, so a silver oxide one will work just fine. In other words if the battery fits properly in the compartment it will work, no adapter required.

Bob, you answer is exactly like those that turned up in my previous search. I am looking for a <i>modern equivalent</i> and can't just try the batteries on for size at the store. <P>

Andrew, I've just wondered into stores in need of batteries, and come out happy. I think the key is to *not* visit a purely retail operation with bubble packed batteries. A knowledgable *watch* repair place, with in-store repair, is the first place that comes to mind. They likely have loose batteries available, and will be knowledgable as to compatibilities between different brands.

Andrew, go to <A HREF="http://www.photoethnography.com/ClassicCameras/index-frameset.html?AsahiPentaxSpotmaticSPII.html~mainFrame">this page</a> and scroll down until you get to the paragraph about replacement batteries.

Weincell MRB400, but as mentioned, the bridge circuit permits the use of the silver S400X

And last time I looked Adorama had 'em.

Andrew, a PX400 is the generic size/number of the battery. Different makers use slightly different in house numbering. If I gave you a Mallory number and the store only carried a different brand, you would still have the same problem.

LR44, A76

Like Bob said, wander into the pharmacy and get a 1.5v battery that will fit in the hole. I bought a blister pack of ten similar to the link above. The hearing aid batteries only last a month or so, a standard LR44/A76 lasts a lot longer.

PX400 is not the same size as a 625 or LR44/A76, it is quite a bit smaller.

I use Exell Photo S400PX 1.5 silvers in my SPIIs. They fit.
