I always use Renata batteries however Seiko ones are also available.
Always buy from a reputable seller as I believe there are fakes about.
Where from. Some from that river sounding site, some from e**l bay. Buy the seller in both cases.

Silver oxide rather than Alkaline too.

Thanks for your reply, I have read on this forum and others that Renata can be problematic and cases of leaking hence me asking for advice.

Mate of mine services military watches and has had many Seiko Gen1 and Gen2 Chrono's
through his hands. He once told me that he'd never seen a case of leakage from the seiko
batteries which were originally fitted to these watches. In some cases they'd been lying
around for years.

Thanks for the recommendation !

Will consider these next time I need some batteries. I've been buying Maxell ones most recently after deciding to move away from Renata (not had any bad experiences of Renata myself, but swayed by the crowd LOL)

Any dead battery will leak if left long enough in a watch!

Avoid cheap no- name batteries sold very cheaply, any of the branded separately packaged batteries should be OK. The key point is to get the battery out when it dies, don’t stick the watch in a drawer for a couple of years.

Cheap batteries can work out very expensive if you not careful/unlucky.

So far 20+ years I have always used Renata and to date never had or come across a leaker of this brand.
