Perform well for rechargeable button batteries
These batteries perform well but not quite as good as disposable batteries. For me, I'm very satisfied with the performance given that the batteries are easily recharged.

Chargeable batteries
Nice replacement batteries, bought for a weather station, seems to loose a charge when it's cold out. But do work.

Good performer!
The coin battery is designed to the spec! I used 2 of them to replace the unnamed rechargeable batteries in my vintage Sony Sports FM Radio Walkman SRF-F1. Before doing so, I took measurement of the battery compartment. After some soldering onto the batteries directly, the Walkman now works like a charm with rechargeable long lasting power! The batteries breathe new life into the old device!

At Last...Coin Batteries with a full charge
I have gone through many cr2025 batteries to find that although they had a use by expectancy of 1 to 2 years remaining. , then we’re all dead on arrival. Got these today, and they test at 100% charge. Thank you Amazon.

Battery Life
These batteries only last for approximately 6 hours. I am using them in a small string of mini LED lights. I started out using the non-rechargeable batteries. They lasted for more than a week without having to be changed. I would have to change these batteries every day. Not worth the money. I also purchased the charging unit. I did charge them for approximately 4 hours and until the red lights turned blue. They were fully charged when I inserted them into the light battery case.
