Conclusion

Batteries are chemical power cells with a specific electrical capacity and energy reserves. The capacity and thus the operating time of a battery depends on many different factors. The most important factors include the height of the load current, but also the ambient temperature and usage patterns play in the running time of a battery is crucial.

As the test results clearly demonstrate, keeps the 1.5-volt lithium battery Energizer Ultimate (L91), as promised. With a capacity of about 2860 mAh and a run duration of 32 hours at a constant discharge current of 100 mA or 2760 mAh and 6.1 hours at 500 mA lithium battery of the alkaline competition clearly superior. In a respectable distance follow the Duracell Ultra and the Varta Max Tech. Close behind is lined with one of the cheap discounter-AA Alkaline batteries Alkaline Activ Energy and Mars.

Particularly noteworthy is the Energizer Ultimate Lithium battery, the very flat discharge curve. This is the energy cell in a position over the life duration of each time-off to provide very high energy – such as in flash units in digital cameras and mobile phones. But mobile devices that require high operating voltage, benefit from the properties of the lithium battery. Other advantages are the Energizer Ultimate Lithium towards the alkaline counterparts, the long shelf life of up to 15 years, low weight and temperature resistance. The latter, I will analyze in greater detail in a later test of the subjects.

A major failure of the Energizer Ultimate Lithium is the high price of around 2.5 € per cell. Duracell Ultra and Varta Max Tech beat at 1.60 euros or 1.75 euros. An unbeatable price of only 21 cents per AA cell batteries are the Active Energy and Mars Alkaline. Thus, each must decide for himself whether his application for the expensive Energizer battery is necessary, or whether an alkaline battery is sufficient at the discount. The Duracell Ultra batteries and Varta Max Tech are relatively expensive and offer over the cheaper batteries only at higher current marginal benefits.
