SH-1 for documentation

Recently I decided to revive an amateur radio transmitter-receiver, which was no longer turning on. A quick Google search showed up a major reason: After two decades, the CPU backup battery might be dead.

This started me on a hunt for a suitable battery, and a way to fit it. I am in the habit of taking photos of how it was before the repair attempt, then the part I need to replace:

The SH-1 can be set for close-ups. The built-in lens is suited for the close-up feature in the SCENE modes. My E-M10 Mark II and Mark IV also have that scene mode, but the lenses I have don't support it.

Back to my problem - nobody knows how the manufacturer Yaesu attached the solder tags to the battery. My super market New World still stocks that battery after 20 years, but soldering copper tags on a new battery blows it up.

Jaycar has a battery holder that matches the solder islands in my FT847 transceiver -

But it needs a thicker battery with a different type number -

Documentation as shown above saves me time when going back to some gear I have not used for years.

The SH-1 can take 16 MP shots, which allows to read part numbers on whole circuit boards, and it can do close-ups without changing lenses.

In addition it does our radio club guest speakers without irritating them, or the audience, with the mechanical shutter I use by default on my E-M10s -

The E-M10s do have a silent shutter, but they distract with their bigger size.

The grab shots above and below are from our radio club newsletter I edit, 'The 29-ER'.

If you have an Olympus SH-50 and SH-1 (I have), or SH-2 (I stuffed mine), or SH-3 (Japan only), don't ditch it!

Those pocket zooms might do a better job for technical documentation than your smart phone, at least in some instances.

FYI - The original battery tabs were spot-welded on; possibly by Yaesu.

Did your battery replacement solve the problem? I thought those batteries were only used to keep the clock running and retain the memories while the radio is un-powered...

Those lithium metal batteries have a 10-12 year shelf life, so the thicker CR2032 will likely not get you anything beyond what a CR2016 would have with half its capacity.

That CR20xx family is a very popular one for coin lithium metal cells. I have rifle scopes with lit reticles that use them, keyless entry car remotes, and even the Casio watches with advertised 10 year battery life use the thinner ones.

I forgot the user reply that says you have to do a full reset to avoid the 'dead-CPU' syndrome. Found the reply again where I saved it, but other stuff happened since then that was more urgent, like completing our tax return.

You are correct. The original CPU battery lasted 20 years at least, so I am not complaining.

Probably not, but my point is, there is a battery holder available for it that fits the Yaesu.

That CR20xx family is a very popular one for coin lithium metal cells. I have rifle scopes with lit reticles that use them, keyless entry car remotes, and even the Casio watches with advertised 10 year battery life use the thinner ones.

And they are still available 20 years later.

Sorry or the lateness of the reply. As I said - other stuff happened. Still, if I can get that FT-847 going again, I will have VHF, UHF and HF in the same set again.

Thanks for coming back to me.

Thanks for the battery-welding info. Might look into this.

The Super Micro is what I used on the SH-1. It is in the E-M10s as well, but you need lenses it can talk to.

Sorry for the delay in answering.
