Review: Reliable Power You Can Trust for Smart Locks - 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. Review: Outstanding Battery Life – Worth the Extra Cost - We use these Energizer Ultimate Lithium AA batteries in our Kwikset Halo deadbolts, and the battery life has been amazing. With regular generic alkaline batteries, we were replacing them every couple of months. After switching to these, they are still showing 100% battery life after 3 months of use. They definitely work better than generic batteries, especially in high-drain devices. If you have something that goes through batteries quickly, these are absolutely worth trying. Yes, they cost more upfront, but the longevity more than makes up for it. Highly recommend. ## Features - 2 pack of Energizer Ultimate Lithium AA Batteries - Energizer Ultimate Lithium AA batteries are the world's longest lasting AA batteries - Performs in extreme temperatures from -40 degrees F to 140 degrees F to ensure reliable use in all seasons - These double A batteries are leak proof batteries, guaranteed based on standard use - Lightweight household batteries last up to 25 years in storage - Includes recycled materials *Steel up to 10% Recycled, excluding 9V ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00003IEMD | | Amperage | 1.5 Amps | | Antenna Location | Household Use | | Battery Capacity | 3500 Milliamp Hours | | Battery Cell Type | Lithium | | Battery Weight | 14.5 Grams | | Best Sellers Rank | #170 in Health & Household ( See Top 100 in Health & Household ) #8 in AA Batteries | | Brand | Energizer | | Built-In Media | Battery Pack | | Compatible Phone Models | Blink cameras, game controllers, drones, smart home devices, VR controllers, flashlights, thermometers, wireless mouse | | Customer Reviews | 4.7 4.7 out of 5 stars (70,958) | | Global Trade Identification Number | 00039800034083 | | Item Dimensions | 0.59 x 3.69 x 4.51 inches | | Item Type Name | Lithium Ultimate | | Item Weight | 0.06 Pounds | | Manufacturer | Energizer Batteries- Consumables | | Model Name | ENR L91BP-2.H4 ULT LITH AA2 EMOD | | Model Number | EVEL91BP2 | | Number of Batteries | 2 AA batteries required.

For any further information you can reach out to us at energizer@custhelp.com or can call us at 800-383-7323. **Q: Anyone know if there is a difference between the "advanced" lithium and the "ultimate" lithium?? Other than price.** A: I thought it would be marketing as well. So I looked in a leading consumer review Magazine and there is apparently a difference. They rated the "ultimate" A few points higher than the "advanced" and for the two tests that they use, one a flashlight test and the other a toy test, the "ultimate" received "excellent" on both tests, while the "advanced" Received "excellent" on the flashlight test and a "good" on the toy test. So I assume the lithium ultimate version lasted longer on the run down test for the toy, which is going to draw energy more inconsistently than a flashlight. If I find a product is burning through batteries faster than expected, I will usually try lithiums. More often than not, the improvement in run time is substantial **Q: Are these “energizer e91” batteries? my co detector requires that type (won’t work with generic aas). where on packages does it indicate e91?** A: E91 refers to Eveready Alkaline batteries¹ (open circuit about 1.5 VDC). L91 refers to Eveready Lithium batteries² (open circuit about 1.8 VDC). The physical casing is the same size. The CO detector may present such a low battery load that it does not like the slightly higher voltage that the L91 battery exhibits when not under a typical load. Contact your CO detector manufacturer and get their opinion on which battery to use (Alkaline or Lithium). I've used both in a number of applications and they've both worked well (although the Alkalines leak while the Lithium never have [for me at least]). _________________________________ ¹ https://www.amazon.com/s?k=E91+battery ² https://www.amazon.com/s?k=L91+battery **Q: What is the voltage of these batteries? they don't work in my handheld mic. non-lithium aa energizer batteries do work in the mic.** A: The open circuit voltage (i.e., just the battery alone) of Eveready's Ultimate Lithium batteries is roughly 1.8 VDC. Under a reasonable load this drops to roughly 1.5 VDC (as Reilly pointed out). This is normal. It is possible in your application -- a very low load on the batteries -- it is possible that the higher voltage is affecting your electrical circuit somehow. I've never run into this but it is possible. Physically they use the same physical case (50mm long, 14mm diameter). But I have seen some designs where the designer got cute and tried to mask off the + battery terminal using barriers to protect from reverse polarity. The result is sometimes the + battery terminal doesn't make contact with the + device terminal. If you're really intent on using the Lithium batteries, I'd recommend checking out those two scenarios. Good luck. And feel free to come back and leave "an answer" if you come up with a solution to use the Lithiums. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Power You Can Trust for Smart Locks *by C***E on April 7, 2026* 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.
