The Energizer Ultimate Lithium is the top performer of all the batteries we tested. It's an excellent all-round battery that's ideal for high-drain devices and it has an excellent shelf life. Being lithium, it's a good choice for cold weather use. But it's very expensive.

Long life at great expense
Pros
Doesn't need replacing quite as often as alkaline batteries
Cons
Over 5 times the cost per hour under high drain as the best performing (#8) battery, 7 times the cost under low drain.
Lithium going to landfill...
Extended shelf life not a real advantage, better to use fresher batteries and keep a small stock regularly replenished.
Recommend it?
No, this product has too many drawbacks.
