I had a bunch of womens watch batteries to change, most of which I didn't know the number before opening so I ordered this in advance. I found I used primarily 364 and 377, but needed many 379 (which aren't included in this pack and had to order). For what I was able to use, they work fine.
Tip: Google for a cross reference table of battery numbers to get the SR, LR number vs. the 3 digit.

I replaced 4 watch batteries and found that 2 of them can be found in this package. Batteries work. However, if I did it again, I'd just buy the battery size I need. Now I have a bunch of batteries that doesn't fit anything lying around.

What you see is what you get: a whole bunch of little batteries. Unless you're in the business (the battery using business, that is), there's simply no way to use even 10% of these before they will expire (multiple years out). Still, at this price, it's absolutely worth it to (with any luck) have the right size/voltage on hand whenever a little battery suddenly craps out.

Great value, lots of batteries that would probably go unused. However, I tested the five watch batteries I bought this for and none of them went beyond "replace" on the battery tester. The used batteries I took out of one watch had more juice than these. The problem is that no manufacture nor expiry dates are printed on the packaging. So just like a box of chocolates, you'll never know what you gonna get when you buy cheapo batteries online. As for my solution, went to my local Batteries plus and got the batteries I needed at abt $4 each, ouch!

I haven't tested to see if their good or not and this review is on the price and quantity therefor. You get four of each size on each card and their labeled easily of the left of card so you don't have to pull out a magnifyer to read battery itself. You can buy one card for a dollar twenty less or get two cards, so it's a no brainer to not stock up on this set. Now I've got the batteries needed for other junk items I have like mini flashlights and I like their neatly organized on these cards no messy clump to have to search through in a jar. Hope this helped, Of course I'm expecting them to be good for three years to be worth the five bucks or so I paid.
