BONAI AAA Lithium Batteries, 8 Pack 1.5V High Capacity Longest Lasting Triple A Batteries Ultimate Power for High-Tech Devices - [Non-Rechargeable]

My outside thermometer sending units had Alakline batteries but got crazy when temps get too low here below zero. The manufacturer recommends using LI-Ion batteries for extreme temps and so far so good. And they last forever.

These do not last as long as other batteries in the same class. They do not overheat, the quality is good, they weigh very little. They are a good value for the money in this class.

Nothing and price seemed fair.

Lithium batteries last so much longer than the best alkaline. If you buy a brand that isn't well known, like Bonai, you'll pay about the same or less than popular branded alkaline and you'll find that they last so long you won't remember when you installed them. I have a pair in one of my TV's remotes that's lasted more than two years. I had any elderly girlfriend (age77) that had two lithium C-cells in her.................You don't want to know. Okay, portable hair dryer that she says worked for almost a year.Don't mess around with old tech; incandescent light bulbs or alkaline batteries: lithium and LED all the way!

These lasted for 4hrs in led powered lights. When we use any other battery, we get 5 days of use. These cost more than the big-name brand batteries.

Had a bad batch of batteries. Customer service was GREAT! They sent me a new set! Working fine! Definitely buying from this company again.

These batteries are a complete waste of money. I ordered these batteries to use in our headlamps for a night time hike. I chose these because they are represented as being lithium batteries, and lithium batteries should last significantly longer than other types of batteries. However, after about two hours of low-level use these batteries were completely dead. In contrast, the original non-lithium batteries that came in our headlamps worked for about 8 hours and are still going strong (they were still working so I put them back in after these batteries died). These batteries are so inferior to regular alkaline batteries. Don't waste you money on these, and certainly don't use them in situations where you will be relying on them - such as with a night hike.

This is an update on my review. The Bonai customer service reached out to me and offered to send me replacement batteries. I still have my reservations about the battery leak issue, but I am definitely pleased with the customer service response.------------------------------------------I bought it in September to use the battery in a flashlight in an emergency situation. I checked the battery today, and there is a leak/corrosion. Amazon referred me to the seller, and the seller's website has no warranty information. So much for the no-leak claim.
