my battery is very tini it says SR626SW can I use this battery for a replacement

See watchbatterycrossreference.com SR626sw is the same as 377

My battery says 377a. Can I use a 377 as a replacement?

NO... they are NOT exact equivalents. The 377a is an alkaline NOT silver battery. The 377's have a much longer shelf and operating life (in most devices), i.e. never use the "a" version in watches. Also note that the 377's have an almost flat voltage vs. time curve, whereas the 377a's have a gradual slope in the voltage. Devices depending on the constant voltage must use the silver version.

What is the manufacture and expiration date?

Energizer customer service told me these packages with no expiration dates are sold for commercial use only. I had the two letter date code off the package and they still could not tell me how old these batteries are.

You do not clearly state how many batteries are being sold. How many are there for $4.76 + free shipping?

title is clear. this sale is for 10 377 batteries
