What else is there to say? Let's read that packaging again. The e² has "Advanced titanium technology and construction..." According to Energizer, the battery does use titanium in some novel way. Energizer also has Lithium-based AA batteries (but no Lithium triple-A's) with claims of 5 times normal battery life, leading to plenty of confusion for AAA battery users. The e² AAA's are regular Zinc-Manganese Dioxide alkalines, and as you now know, you're not getting 5x life. Sorry.

The second half of their claim promises "stronger, more powerful performance." The extra 10% life doesn't seem to be all that significant, and after looking at Energizer's own technical data, we're not sure what the big deal is with the AAA batteries. Energizer has a great set of details on their batteries online, and their site claims that the e² AAA has a capacity of 1150mAh. Check the standard Energizer AAA stats, and guess what - they also have a capacity of 1150mAh. Whatever.

We gave you the goods early on so you wouldn't have to read this far, but we'll say it again. 10% longer life for 23% more cost. 'nuff said.
