MAXELL 364 SR621SW, AG1 - 1 Pack of 5 Batteries. USA GP164.

Just what was ordered and great item for the price and arrived early.

Easy to use but sometimes hard to get out of package at my age.

These batteries are very affordable and they're a great product. I use these batteries for my Watch repair and Watch Maintenance business. My clients are always satisfied when I change their batteries with these batteries. These batteries last for up to three years. They are of exceptional quality. You can't go wrong with these.

Don't know if they will last till 2027 but at least they put a date on the batteries. At least there are some expectations for battery life.

Individually wrapped; first two installations running fine; expiration date of 2022 which is plenty reasonable; and free shipping to boot; I'm happy

This is my second order from this company. I'm very pleased with the price and quality of the batteries. Super fast delivery.

All that I can speak to is that delivery was fast, the price was low and the packaging is exactly as shown in the picture. I paid more than this locally for one battery for a watch I bought and purchased these as back-ups. So, at the moment I can make no comment as to how long they last or if they work in my watch. I'm just "assuming" they will work.

purchased a 5-pack of 364 batteries in April 2024 (see attached).Each battery appears to last about a month before it dies. I’ve been through 3 batteries already and just replaced a fourth today. That’s almost exactly 1month each. I don’t know if it is the watch that is suddenly battery hungry or if maybe it is a bad batch of batteries??
