Battery for Avocet 35
Sheldon Isaac
I've tried several stores, they don't have the battery for my Avocet 35
cyclometer.
Where can I get it?
Thanks,

I got one at Target -- an Energizer 357 (LR44/SR44W). Works fine in my
35.

But isn't a 357 a 1.5 volt?
The Avocet manual says use 1.35 volt.

Oops, it's actually a 1.55 volt battery. I just took the battery counter
kid's word for it that it was the cross-referenced battery, took it
home, popped it in and it seems to work correctly. According to the
online avocet 35 manual, it looks like it calls for an AC675 (1.4 volt)
instead of the 357. Guess it's back to the store...

Most Avocet cyclometers were designed around 1.35 volt mercury-based
batteries. For environmental reasons, mercury batteries have been made
extinct. This causes problems for many photographers with older cameras
and light meters that were made for mercury batteries, because there are
no other long-lasting battery chemistries that put out a consistent 1.35
volts. For photographic applications, the recommended substitute is
zinc-air batteries, but they have a much shorter lifespan.
Unlike old CdS light meters, cyclecomputers are digital devices, and run
happily on higher voltages, as long as the voltage isn't high enough to
fry the circuitry...but a 1.5 volt button cell couldn't fry anything, so
this should be no problem, as long as the physical fit is OK.
The SR44/MS76 is available in both alkaline and silver chemistry.
Silver is more expensive, but is much longer lasting.
By far the best batteries for cyclecomputers are lithium cells, but
these are 3 volts, and won't fit the Avocet battery compartment anyway.

>cyclometer.
i didnt know ppl sold the apparatus to smash atoms to ppl, not to mention the
whole 1.xx volts issue....
i wanna see top quark at home too........
no offense
dan-if this was rocket science; youd be wondering why you were burning-M.

aid batteries. They come in a pack of either 4 or 8. I think the
4-pack goes for $1.99 on sale. They are 1.4V.
I've been using them in my Avocet 40. They seem to last about a year
each.

If no place else, from Avocet direct:

any longer, due to disposal problems. However, I've used the type 303 cell,
which is either silver oxide or alkaline, and it works fine despite the slightly
higher voltage. Seems to last about a year.

The type 303 may only last half as long, but it's less than half the cost.

Thanks a lot to you and others.
I put a too-thick 1.35 WeinCell ($4.99 at Larmon Photo on Chestnut St, Phila)
in, and although I couldn't snap on the battery cap, I held the cell in with
sticky tape, and then slid it into the mount.
The display was fine initially, and I thought I'd just use it that way till
this battery ran down. Hah! Later the same day the screen was dim again,
almost invisible digits when viewed straight on, like it was when Avocet sent
it back to me.
Perhaps there's something wrong inside, which is draining the battery?
Thanks,

To isolate the problem, beg, borrow, or steal a multimeter and check the
battery voltage. If it was at 1.4 or 1.3 volts initially, and drops down to
under a volt in one day, then clearly the computer has a problem.
But it sounds to me that you have the wrong size battery. It has to make
GOOD CONTACT not only with the center tange, but also around the
circumference of the battery. Without using the battery cap, you may not
have adequate pressure on the contacts.
