You can never have too many batteries.

Think back to the last time the TV remote died. Or your alarm clock gave out. Or, God forbid, your electric toothbrush sputtered out its last rotation just before work, and you tore the house apart looking for replacements, only to come up short?

Luckily, for those who perennially live in fear that their batteries will give out, there’s a solution. And even luckier? It’s on sale.
