What would you do with longer lasting batteries? Power your camera, your remotes, or simply keep the peace longer by making sure all your kids' toys are ready for play with the new Fusion batteries from Rayovac. This new battery is tested to be "35% longer lasting than Energizer Max", which means you can buy less batteries and worry about technology shut-downs a whole lot less.
As someone who is admittedly very frugal and has been known to shop at dollar stores or purchase off-brands, batteries are one of the few items I refuse to go this route with. Those off-brand batteries end up costing a whole lot more in the long run because they only last a small fraction of the time of a brand like Rayovac, so you end up compromising a lot to save a little.
