** For devices ceases to operate when 1 of 4 batteries brings less power, a simple battery tester has proven, since the remaining batteries are still used elsewhere, eg. As in clocks or smoke alarms.
- The Power check function of Duracell is therefore unnecessary for us. They did not work with the tested batteries from the outset. Either nothing is displayed or an unrealistic for a new battery level.
** Between the performance of batteries from discounters and brand batteries we have been able to find only small differences that do not justify the price difference. Sailed us so far are neither brand batteries even discounters batteries, but the cheap batteries supplied with devices and older rechargeable batteries.
For the price-performance ratio: 3 of 5 stars.
