Energizer Ultimate Lithium AA Batteries (2 Pack), 1.5V Lithium Double A Batteries

These Energizer lithium AA batteries work great and have been very reliable. They last a long time and are especially nice for devices where I don’t want to constantly change batteries. They’re a little more expensive than regular batteries, but the performance makes them worth it.

I use these batteries in my Blink Doorbell. I have used many brands but these seem to last longer than any other brands. I prefer these batteries and they are a GREAT value for the money. I will always use these specifically for my doorbell camera because I trust that they will last and not fail me.

Of course these are five star. You get what you pay for and if you own a blink camera, you know you need the best batteries possible. I do have rechargeable batteries, and you have to be very careful with the brands that you buy because after a use or two and a blink camera they can peel and have issues. I wish I didn’t have to buy batteries that I couldn’t recharge – however these last so long it doesn’t make me feel that bad. Also, they work great in any Hydra, music, equipment, gaming, equipment, or anything else that needs lasting power.

Energizer Ultimate Lithium AA batteries have been around for years, which makes them a safe and reliable choice, you know exactly what you’re getting. They have a strong reputation, and that’s one of the main reasons I chose them. I just received and installed these in my smart front door lock, where dependable power is essential. The last thing you want is your lock failing due to weak batteries, so choosing a trusted brand really matters here. They are definitely more expensive than standard batteries, but for something as important as home security, it’s absolutely worth it. Reliability matters more than saving a few dollars. So far, everything is working perfectly, and based on the brand’s reputation, I feel confident they will last. If you want peace of mind for important devices, this is a great choice.

The new lithium batteries are worth the money That I paid for them. They last a lot longer than the energizer batterie’s that I was using. I would have to change them every two weeks. I use these in the security cameras that’s on the front, back and sides of the house. I am thrilled with them and I haven’t had to change them yet and it’s been over three weeks.

Bought for my security cameras for winter. Easy install. Could last longer. Pricey.

Ordered 100 batteries and received six packages of 18, so a bonus for me. Was hoping for loose batteries in a box but they can't in thick cards with thick plastic coverings. Long life at least. Using for blink cameras at multiple locations.

I need these batteries for my wireless webcams. They work fine in thie application and the Amazon order was exactly what I wanted.

Wir haben diese Batterien von Energizer bereits mehrere Male gekauft und sind damit sehr zufrieden. Preislich sind sie natürlich schon deutlich teurer als andere Batterien, aber dafür zeichen sie sich durch eine sehr lange Lebensdauer aus. Die Batterien sind wirklich leistungsstark und halten sehr lange. Wir nutzen sie vor allem für unsere Blink-Kameras. Und im Vergleich zu anderen Batterien können wir die Kameras trotz vieler täglicher kurzer Video-Aufnahmen mehrere Monate lang nutzen. Das war bei vielen anderen getestenen Batterien leider nicht der Fall und wir mussten die Batterien sehr häufig (ca. alle drei Wochen) in den Kamers austauschen. Mit diesen Batterien laufen die Kameras mehrere Monate lang fehlerfrei. Bislang ist keine einzige Batterie ausgelaufen und sie funktionieren sowohl im Hochsommer als auch bei Minusgraden draußen ohne Probleme. Daher eine absolute Kaufempfehlung!
