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.

Great quality for the price and very reliable — I’ll definitely keep buying these.

## Questions & Answers

**Q: What is the capacity of  the 1.5v batteries in mAh?**
A: Thank you for reaching out to Energizer.The capacity of the 1.5v is 3000 mAh.
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]).

**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.
