Hi all.

I have noticed that these batteries have recently been introduced by a UK parts supplier. Relatively decent price too (for now) - and that they are made by Seiko.

Does anyone have experience of them .

Thanks

Here is a blurb on them from a seller. http://www.microbattery.com/products/seizaiken-watch-battery

I have not seen them here in my area malls. Mostly Panasonic watch batteries are sold. I recall seeing some Sony batteries on the shelf in a large electronics store but their price was the highest. For low end AA, AAA etc batteries, many are Chinese made. I always buy the Panasonic ones at my local mall stores. Average cost is $5.
I am sure the Sony batteries are excellent but you pay for it! Sony company just went through a financial shakeup, being the last holdout to revamp its company to save huge losses in revenue. Panasonic and Sharp already bit the bullet and cut areas and staff to stem the huge losses.

I am using it.
They are about the same price as the Sony, Maxwell....etc.
So far so good.

*It sure looks good on Seiko watches.

Wasent there a battery with a similar name mentioned a long while ago and they were fakes ?

Obviously not saying these are fakes !!! but the name was very like this or am i totally wrong ?

 

[xzqt]

Not sure about the fake.
But the inner pack pic looks like this/below :
(same but this is a 920 battery which i just changed)

So why does a silver oxide battery package have the symbols for mercury (Hg) and lead (Pb) on it?

I always use Seizaiken now, SII made - and OE on a lot of Seiko watches. http://www.sii.co.jp/en/me/datasheets/silver-oxide/seizaiken/ http://www.sih.com.hk/sih_eng/products/bat_01_silver.html

Tony, here is a wikipedia page ...scroll down to the list of cell compositions and you will see that silver oxide batteries have a minute bit of mercury but no lead listed.

To be politically eco friendly, the tag says NOT to discard them in the trash can.

I agree, it's probably to encourage recycling - but Seizaiken's Silver oxide cells don't use mercury anymore - http://www.sii.co.jp/en/me/datasheets/silver-oxide/seizaiken/

Cousins have started selling them so from there they are very probably above board. Bit cheaper than Maxells and Renatas at the moment but they will probably change when they get more popular (who mentioned diesel/petrol !!).

I have seen some Maxells and more so Renatas leak even before they are dead so the Seizaiken claim to have better crimping technology plus they are nade by Seiko, have an appeal

 

[Grammarofdesign]

I just got a few batteries from the Seiko Service Center and they are Saizaiken.

Take from that what you will.

Thanks for all this good info guys....especially about the crimping technology...

I've used them on my H558, very good and lasts longer than a Renata. JMHO
