The batteries with Alkaline technology provide up to 118% more power than other comparable batteries and are known for their long life. The Philips LR03 1.5V Alkaline batteries have a low self-discharge. This makes them very suitable for electrical devices that use little power over a longer period of time. Think of devices you don't use often such as clocks, remote controls, wireless mice and keyboards, flashlights and radios. In contrast to Lithium batteries, these Alkaline AAA batteries also last longer, because they hardly run out.
