Not so super at all
Skip these. They're not the cheapest AA you can buy, but they're almost the worst performing. For devices that draw a lot of power, these batteries really fall flat compared to the competition. We take particular issue with their claim that these have higher voltage during discharge than the competitors.
ACDelco's claimed battery performance
ACDelco's actual battery performance
They simply don't have the performance that their advertising claims. In fact our tests show that it is nearly the exact opposite, with a Duracell CopperTop providing higher voltages throughout the duration of the discharge at multiple different discharge levels.
In addition their chart clearly shows that their cells start discharging at around 1.7V, while in none of our testing did any of their cells show more than 1.6V.
Cheap
Container is uses minimal packaging and is easy to open and close
Poor battery life in many applications
They lie about their battery performance
