Editor's Pick: Changing batteries in a Blink camera means climbing a ladder to reach the front door or a back corner of the yard. Pop in these two lithium batteries and they'll last nearly two years, saving you the hassle of repeated trips. Lithium batteries are about 30% lighter than alkaline ones, so they won't add extra strain on your mount when it's hanging on the wall. Store any unused ones in a drawer—they'll still have power after twenty-plus years, so you can grab a pair and swap them in anytime.
