Great quality and Value for money - These lithium batteries are game changers for many devices - I use them in Blink outdoor camera and they are amazing and literally last for years before needing changed. They have a great capacity and are very powerful - A bit more expensive that non lithium but they are a totally different battery.

These are expensive batteries, but they are lithium. The main advantage and why I got them is because they do not leak over time when stored or used for extended periods for low power use cases, such as Elevation Lab's AirTag 10-Year Extended Battery Case.

Seems to last longer than some batteries

You may be looking at these and asking yourself "Why would I spend so much on batteries? I can get them way cheaper from Duracell." Note these are Lithium batteries. Not alkaline. Do your own independent research to confirm my claims. I've switched to lithium batteries almost entirely for the following 3 reasons: - They have very long shelf lives. Ever pulled a torch out of the cupboard a few years after you last changed the batteries - just to find it's struggling or dead? As per what research shows online, I don't find that to be the case with Lithium batteries. They have a superb shelf life, and even hold up well to the cold (great for that little torch you keep in your car's glovebox). - They don't leak. I've lost several tools/gadgets to leaky Alkaline batteries. Completely corroded the battery contacts beyond realistic repair. These, I can confirm, do _not_ leak. - They will sustain high power output. Not often a necessity of mine - but occasionally I grab them for use in an external camera flash - and they "recharge" the flash fast, every time. They can sustain that high power delivery. What _isn't_ different (in my experience) to cheaper Alkalines? They don't "last" any longer in terms of active use. Clocks, thermostats, stuff like that - I haven't noticed any meaningful difference in how regularly I'm replacing the batteries. These cost more, so you may wish to gamble leak-liable Alkalines for those situations. Personally, having lost a thermostat to a bad Alkaline leak, I'd rather pay the extra for Lithium batteries than £35 for a whole new thermostat. Also make sure the appliance you're putting them in says its Lithium compatible, as the voltage can be slightly lower (and the "drop off" of voltage when the battery nears depletion can be _very_ different to Alkaline). Smoke detectors, in particular, might be something you choose (given your life depends on them) to stick with approved Alkalines. I put these Lithiums in our smoke detectors - and they do tend to not give the "low battery beeping" so reliably. Therefore it is _even more_ critical that I routinely check the smoke detectors by pressing the test button. But, except for those small caveats, Lithium is absolutely superior. You can buy a pack of 10, leave 3 spare, and in 3 years' time - they'll still be perfectly usable.

Work well great battery life and of a good quality, work well in our outside cameras

Long lasting

These batteries are expensive but are value for money. I use them for Blink cameras and doorbell. Two of the batteries still have a charge after more than 5 years. The doorbell uses 2 batteries over 15 months and more
