Battery price comparison

Recommended Posts

Looks pretty useful information. It would be interesting to see a comparison of their respective measured capacities.

My suspicion is that there might not me much difference. On the other hand, how well constructed, and therefore how prone to leaking the cheaper brands are, may well be the most important factor of all, but  I doubt if there are any useful resources that go in to that much detail.

My limited experience suggests that the cheaper batteries may be slightly more prone to leaking, but eventually, if you leave them in the watch long enough, I suspect they all run the risk of leaking in the end. I have found furry Renatas and furry cheapo Shezhen market specials but my gut feeling is that the cheapos are more likely to spill their guts than their more expensive cousins.

I don't really know why I did this, but learned few things in doing it. Maybe it can be useful to someone.




Have been used Seikazen when the Retina has not be available with no issues.

Been using them for a while watchmaking as a hobby.

Think I read on the Cousins site a while back that they are Seiko batteries which was good enough for me.

I've had two Renata batteries leak years ago. Lucky I caught them in time to minimise damage.
I've now used nothing but Sezaiken (Seiko) for the past 4 years. 44 quartz watches and no issues yet.

    • I read somewhere (maybe the tube) that you can cure a lot of evils if you wind the spring up as you would into a mainspring winder (though a MS winder would be too large and this would have to be done on the flat of your bench for example) until it is fully and tightly coiled.  I gather this gives it its shape back and you can move on from there.  Maybe a bit of an ask for your spring though !!  Maybe worth a try as not much to lose !!
    • Well, I have just written to Mr. Sudarson at www.oldswisswatches.com and have politely asked him how he can help me with this problem. I'll keep you updated on the progress. Yes, I don't think you're wrong to assume that the cost of living and wages in India are extremely low. An alternative explanation could possibly be that the repair prices reflect the same kind of quality that the spare parts they sent me had, but I wouldn't really know.
    • I inherited a clock over 30 years ago that must have been in the family almost from new. It is identical in appearance, size, as a 1907 Urania 400 day anniversary clock but apart from a serial number stamped on the back 32638, (in the same place and font as the Urania) there are no other markings except for an S and an F on the circular weight.  The dial has no markings but I understand that this is not abnormal as often retailers added there own mark.  Is there any knowledge of a likely resource that might help provide any info. Thank you.
