I'm wondering about getting the maxium runtime out of a AAA battery on high mode in an itp A3.
For AAA rechargeables I'm pretty convinced that an Eneloop would give me the best runtimes on high. However, I'm wondering if there is a way to do even better. I hear some people use a 10440 on medium and get the same amount of light as a AAA on high; would this give better run time?
Do alkaline primaries beat an eneloop? For those of you that don't know the light, it draws about 0.85 amps on high. At that current would the fancy (expensive) Energizer lithiums last much longer than a standard primary or an Eneloop?
I intend to the operate the flashlight mostly with rechargables. But I'm thinking about using it as a back-up in a night running race. Since it is a race and this would just be the backup light I really want to minimize weight. I don't mind paying a bit extra for batteries since it is a one-time thing.
If I can't find something that provides more than an hour run time I probably have to use a AA or CR123 size flashlight as the backup...
