Has anyone seen the Energizer E2/E3 technology Lit ion Batteries? They boast the fact that they have lit ion technology and lasy 4 times longer than the standard Alkaline batts...They are AA and 1.5 volts I also looked at the stats..almost all the same as a standard AA bat but lasts up to 4 times longer in digital applications. What I'd like to know is if anyone's tried these? As I do want to give em a try but I don't wan't to end up frying my GP32... I just noticed these last week when trying to find a longer lasting battery than my current Duracell copper tops.
