Renata 357 SR44W Batteries - 1.55V Silver Oxide 357 Watch Battery (20 Count)

Title sums it up. The issue with batteries like this often comes down to factors beyond the brand reputation (which Renata is fantastic). The main variable is the seller/the seller's stock, which can be nice and fresh...or old, improperly stored, and outright counterfeit.) Which is why you see such mixed reviews on batteries like this, and the reason I'm mentioning the product and seller name: The SR44W 2 pack, sold by Galtex, shipped by Amazon.) The expiration date for these was still more than 2 years away (02/2028), the voltage out of the package read as expected, and they functioned in the device as expected. Of course reading the voltage of a cell with no load doesn't do a great job of showing remaining capacity, especially with silver oxide's voltage stability, but it's a positive sign nonetheless.

Perfect, no problem

Used to replace the battery in my Rolex watch. Good value for the money and hopefully the battery will last a long time. Use a special watch back tool to remove your old battery for easy replacement / removal.

Good deal

Working great

I have a lot of electronic measuring devices (calipers, etc) that take this size battery. The problem is standard alkaline-cell LR44s last a very short time in them. SR44Ws or 357 cells are silver-oxide batteries, so their discharge curve is much flatter, holding a higher voltage longer than the LR44s. This means they last much longer in my calipers. They cost more than the alkaline cells, but are more than worth it for the longer life and reduced inconvenience of constant battery replacement. That said, I don't trust Chinese-made versions; I've had bad results with some of them. Renata is a Swiss company, and I've found them to be consistently reliable. (Pro tip if you have big bucks: Cheap Chinese calipers, height gauges, etc draw current even when the display is off, so they drain their batteries even if you aren't using them. In contrast, Mitutoyos; actually *are* off when you turn them off so batteries last many, many times longer in them. Unfortunately Mitutoyos cost $125-150 instead of $10-25 per pair, so for most of us constantly buying batteries ends up being the more affordable approach :-/)

Great batteries and great price!!

Exactly as advertised.

Ordered these for my film slr as recommended by manufacturer for their voltage stability ( Silver oxide vs Alkaline ), bought these in the past, and were long lasting. Does the job well.

The batteries work perfectly in my Olympus OM10, Ricoh KR5 & KR10 Super 35mm cameras and a hand held Jessops light meter (26 years old and still works).

They are fine, thank you, and arrived promptly
