• Other Thoughts: We read about using lithium batteries in a flashlight. We bought these for a cruise we just took. We are using the first two batteries! Worth the extra cost for the amount of life you get and we don't have to pack and take the recharger!

• Other Thoughts: These lithiun batteries are just the thing for electronics when you go into the backcountry. At 1/2 the weight and many times the lifespan of batteries, these are what I always use for long trips.

• Other Thoughts: The product was packaged well. I was impressed with the charged on the battery. When tested the reading was 3.7V. I would purchase from this vendor in the future.

• Other Thoughts: Used these batteries for wireless alarm system remote sensors and they work fine. The date on the battery is manufacture date, not expiration date. These have been installed for a few months and are still holding a full charge so the drain is also very good. I recommend these as a replacement without hesitation.
