Duracell Ultra Power Aaa Batteries 4 Count (Pack of 2)

Great batteries, cant go wrong with Duracell. They are still going strong.

Id buy them again! Plus the price was great!

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 1.59-1.60v I didn't do a controlled ah drain test to confirm.

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

Duracell Ultra 90hrs

Duracell Procell 85hrs

Amazon Basics 75hrs

Harbor Freight 75hrs

Energizer Lithium 55hrs

Energizer Rechargeable 40hrs

I still want to test a handful of 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 will do better with lithium. Low ah and voltage required devices can use rechargeables well. Headlamps however (confirmed in this and a Petzl), do not do well with lithium or rechargeables, both die rather quickly.

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
