I compared these to several other AAA's in a headlamp. I needed the longest lasting headlamp life regardless of cost, for week long treks on a trail.

These usually are about 1.61g-1.62v new, which is about the same as the Maxells. These have drained less than 0.02v in the 6 months I've had them in storage, whereas the Maxells have drained about 0.03.-0.04v in the same time. These also have about a 10year expiration date from when they were purchased, and the Maxells only have about a 5year expiration date. These weigh 11.59g, the Maxells weigh 11.51g.

In my Black Diamond headlamp these ranked as follows (ran non stop until I couldn't see a chart 10ft away - which means the headlamp was useless/dead) :

Duracell Ultra - 90hrs
Duracell Procell - 85hrs
Maxell - 80hrs
Amazon Basics - 75hrs
Harbor Freight - 75hrs
Energizer Lithium - 55hrs
Energizer Rechargeable - 40hrs

I still want to test others, but so far these are clearly the winner for my application. Note: different devices can use different batteries. Quick and high drain devices like a camera flash or GPS will do better with lithium. Low ah and voltage required devices can use rechargeables well. Most non-regulated headlamps however do not do well with lithium or rechargeables, both die rather quickly.

I should have read the reviews. But they were Duracell so I didn't. Shame on me. They expired in 2012. No bargain here.

Used in an alarm clock, it's very important that these batteries be long-lasting and reliable. This is the best AAA battery out there.

Be sure to check the expiration date on your batteries when they arrive. I got some supposed to have a 5 year expire date and they only had 3. AMAZON tried to make it "right" and send me some with 4 year expiration dates while allowing me to keep the ones with 3 year expire dates::::-CAVEAT EMPTOR
