watch batteries - what brand, where to buy

[TheUnicorn]

does anyone have any recommendations for AG1 size button batteries, I've exhausted my old stock, which were getting less and less reliable. looking on amazon there are very few brands that I recognize, so are they all pretty much the same quality?

I've used Renata batteries for the last few years. Swiss made, according to the packaging, anyway. No issues, except when I've had them in stock for too long. Initially, I bought them from H S Walsh, but recent supplies have come from Amazon.

A quick interweb search on 'Renata AG1' suggests both Amazon and Ebay suppliers, and that the Renata number is 364 - but that probably should be checked. They seem to cost about £1-70 each, less for quantities, of course.
