As a gadget lover, we all know that most of our gadgets require batteries. The problem is that most of the batteries out there doesn’t last as long as you wanted. That’s why Energizer has created the Ultimate Lithium Batteries in AA & AAA. Do they last longer than other batteries?The packaging on these batteries is similar to any other battery packaging you’ve seen. Energizer says these batteries are the “World’s Longest Lasting AA Battery in High-Tech Devices”. They also say that it lasts 9 times longer in digital cameras versus Energizer Max.
So how does the Energizer Ultimate Lithium Batteries stand up against the other competitors? I tested it against 3 different rechargeable batteries and 2 different standard batteries. I used 2 of each type and did a battery drain test on a TerraLUX Lightstar 100 flashlight which takes one AA battery. The LED flashlight is set to high at 100 lumens and left on until completely turned off. Manufacturer’s approximate run time on high is listed as 2 hours.

From the battery drain test, these new Energizer Ultimate Lithium batteries definitely last considerably longer than the others. I understand that I didn’t test it against other lithium batteries. But I will definitely choose the Energizer Ultimate Lithium batteries for my next battery purchase. MSRP for a 4-pack AA Energizer Ultimate Lithium is $9.99.
