Top batteries, very low self-discharge, excellent tension maintenance, more than 50% charging current savings. Applicable up to -20 °.

Because we have always annoyed that the standard NiMH batteries have ever very quickly to capacity by self-discharge or very fast voltage unstable were, we have the eneloop batteries already used in the previous version with great success. The batteries eneloop XX but the absolute top product. We put them in the meantime anywhere. This applies also for outdoor use, because they are up to - and so very suitable 20 ° C and are therefore for example, external sensors, temperature sensors of weather stations. We have found that they hold up to 5 times longer. Therefore, a further purchase of enelope XX.

The following have been found that are buying decision for us:

+ Very long tension.
+ Very low self-discharge.
+ Charge is expressed in months and even after one year are available, although slightly mitigated.
+ Are quick to load.
+ Can be used down to -20 ° C. Very good!
+ Easily use in battery-powered devices. We know in our currently no devices, where they would not be used.
+ Due to the very low self discharge eneloop XX kept the battery up to 5 times longer than normal NiMH batteries depending on device type. Because of this, they had to be charged much less often again. The charging current savings by charging our batteries, which was considered more than a year, resulted in a saving of over 50%. This was measured by a power consumption meter from Brennenstuhl, which was connected before the battery charger, a Ansmann Energy 16. There were more than a year the loading times and the used kWh measured (battery AA and AAA). This was a very big surprise. But that can also measure each for themselves objectively to compare more than one month. In addition, we used a battery tester, with which we can measure the voltage and the capacity of each individual battery. It is clear that the charge is maintained for longer, thus less loading operations per unit of time, characterized less charge cycles, thus less power consumption, thus less battery wear.
+ The batteries are processed very solid.
The +/- 500 recharges, are not a problem because these batteries are not as frequent charged by the low self-discharge NiMH batteries as the old ones.

A note yet: It is very important that the charger the batteries with high capacity and can load. This can be seen from the charge time table of the charger. Stands at a 1.2V AAA battery in the capacity column (not to be confused with charge current!) Eg 180-500mAh, you get a battery with 900mAh never fully charged, at 500mAh is final. It makes sense, therefore, a battery charge gauge to have with which you can measure the voltage and capacity.

Conclusion In brief: Overall, a very good product with high technology. We have already ordered more for us. In our view, a clear buy.
