What can go wrong with batteries?

I found what I wanted and at the right price. The batteries arrived in just a few days. Everything went according to plan.More detail ...

Of all SR series button cells the most energy storage

The 357 cell made in silver oxide chemistry (like this one) has the highest capacity of about 200 mAh and as such it has numerous equivalents including:

AG13

SG13

LR44

LR154

A76

S76

157

303

LR1154

SR1154

1166A

1107SO

1131SOP

SR44 (size name)

Since the silver oxide cell contains more power than the alkaline or MnO2 cells it is a universal replacement for all of the above cells so having silver oxide 357 cells on hand will replace ALL of the cells listed above with equal or likely better performance. Also the silver oxide chemistry has a very low self discharge so its not likely that these high quality cells will go dead not being used.



If you wonder why an inferior battery would be made with ~1/2 the power of the silver oxide it is because products can be shipped with these inferior cells dirt cheap operate for a short while then require new batteries. The mfgr usually sells the 357 at a high markup down the road and profits on the batteries where they couldn't on the product. Here they are close to a dollar in watch shops or stores they may be sold for 8-10 dollars PER BATTERY which if you use the 357 or equivalent sizes in any small device makes it advantageous to keep a card of 9 cells on hand.



These cells are also stacked often - our lab handheld pH meter uses a stack of 4 for ~6V but lasts forever. For $5 we can change all 4 batteries but running to the store we would pay $32!



Finally the 357 is not commonly found in watches due to its large size and modern watches low power usage. There are usually 2 batteries for watches that are identical - but one will be able to supply higher power for watches with lamps or other devices while the other is intended for watches that just have a ticking second hand display without any electrical lighting. Here again the higher power battery turns out to be the better deal since it will run any watch longer without replacement.More detail ...

Great value

Lithium batteries have a long shelf-life so if you have the money to invest on quantity you'll save a lot by buying these. This is a 12 pack of 2-batts/pack so you get 24 batteries. Highly recommended.More detail ...

This is a good deal. Absolutely satisfied with buying batteries this way.

They last just as long as if I were to purchase in the store. I was really tired of having to run to the store everytime the watch batteries ran out. These batteries fit all three of my watches. Just check the numbers on the back of your existing batteries. You should be able to type in an Amazon or even Google search to figure out if the numbers here match. Lots of different number/letter combinations equate to the exact same batteries. I am not sure why but that is the way it works. These have worked well for me.More detail ...
