Editor's Pick: When a Blink camera is mounted outside the door, changing the battery means climbing a ladder and removing the mount, which is quite a hassle. These lithium batteries hold up well in cold temperatures, so outdoor power drains more slowly in winter and they last for months once installed. Keep a couple of spares in a drawer so you won't have to place a last-minute order and wait for delivery next time you need to swap batteries.
