20 357 SR44 Silver Oxide Watch Electronic Battery

It's a bunch of batteries, the nicer silver oxide type, which I find longer lasting. I use them for an old calculator and for my digital calipers. I don't know how long their shelf life is at this point, but so far they are working ok. My calculator takes three of these batteries. There's enough of them to have spares around, which is nice, since stuff always seems to die when you don't have replacements handy! Not too expensive and long lasting, seems good to me.

I buy and sell used cameras and I run through these batteries pretty quickly. I've only had one dud so far and they all have consistent voltage. Excellent value for the money.

Purchased these batteries for use in an automobile tire pressure gauge. The ones they replaced, had been in the pressure gauge for years. Good price, good value and quick shipping.

The LR44 or other subs of this type is an alkaline battery. They will work in digital calipers, micrometers and so on. However, as the battery discharges the voltage will not be steady, causing erroneous reading or having to re-zero digital tool. The SR44 is a silver oxide type. They maintain their voltage throughout the life of the battery until they finally go dead. Generally, the silver oxide is more expensive than alkaline type.

these will be finding their way into various lights and other devices we have soon

The SR44 battery works a lot better than LR44 because they keep their voltage constant for the most part of their useable life. I use them in my film cameras for automatic exposure and metering and so far they have lasted longer than any LR44 batteries I've put in my camera. Highly recommended.

Based on testing each of the 20 cells for no-load voltage & each tested at 1.59V. I'm not aware of any other cell type that would typically measure in the range of 1.55-2.0 volts; although I have seen cheap alkaline AA batteries measure 1.56V on initial check, but these voltages dropped rapidly. It will be some time before I can report on longevity of these 'silver-oxide' cells.

Returning this product in less than 15 minutes of opening. 4 Sleeves of 5 received. First 3 batteries opened and tried failed. Tester indicated "replace"!! Don't waste your time or money!!
