Duracell, the battery famous for its copper top, is back with the Duracell Ultra Advanced with POWERCHECK battery which is capable of letting you know just how much juice it has left within via a built-in gauge that is located on the outside of the battery. All you need to do is press both white dots simultaneously and the gauge will show a reading on just how ready the battery is for its next usage, be it for a clock or a remote control toy car. This isn’t exactly new technology as it has seen action in other brands over the years, but at least you can be comforted that the Duracell Ultra Advanced battery line was specially designed to meet the demands of the widest range of devices consumers, lasting up to 30% more in toys compared to its predecessor. Needless to say, this one costs slightly more expensive than the vanilla version.
