🔋 Renata 321 / SR616SW Watch Battery Pack (5 Batteries) Review

A good manufacturer, in the picture, though, the packaging was a box, it came on a blister. I hope the filling is not worse.

Excellent batteries as always. We have dozens of watches and only trust our expensive watches with Renata batteries. They are sent via first class mail and usually arrive in just 3 days but sometimes it takes 10 days. The price is also unbeatable! A pack of 5 of these batteries costs less than an unnamed battery from Walmart or a jewelry store.

Purchased September 2015 to replace my wife's watch battery. After two months the battery showed 0.8V and had to be replaced again. I thought it might be a bad one in a 5 pack. It's February 2016, I had to put in a third one. Then I look at the packaging, the best before date is 12/2017. This seller appears to be clearing out old stock on the shelves. DO NOT BUY FROM THIS SELLER! [Update 05/15/16] Three months later the third battery was empty again! Now go on with four! And there is NO REPLY…

They fit my two watches perfectly and work well. Most importantly, it costs a lot less than if you bought them at retail. If you manage to open the back cover of the watch, changing the batteries is not difficult. Buy a Watch Opener Key/Tool at Revain.com for less than $10. These batteries cost $4+ for 5 packs. Overall, replacing two batteries in the watch cost me less than $10 (including the cost of buying a key). I have no idea how much it will cost at the watch dealer. I suggest you do it…
