I have been buying these Li-button cells from various on-line sellers & have received batteries with a variety of date stamps, some don’t have any dates. Maybe in Chinese. I buy on line as the retail price of these cells in Australia is very expensive.
The latest batch I bought were stamped 2014-12. When I queried the seller I was told that this was the date of production !
I have never heard of this - how is the user to know how long the batteries are good for.
I suspect that the dealers buy up old stock that is close to the Best Before Date & then re-sell.
Any comments ? Can someone recommend a dealer that sells batteries with a good Best Before Date ?
