I tend to leave CFLs on rather than turn them on/off for short periods because of this, but I wonder the cost of replacing vs. wasted electricity (they can be costly, for example the Philips bulb I use in the bedside lamp is at least 7 years old).
i also do the same, i was never able to accurately calculate the life loss per on/off cycle, i consider 3 hours of life loss as my best current educated guess
My i4 charger charges the aaa eneloops not so good like my b6 does…
If charged and discharged with b6 I get around 720mAh with my i4 I get 100mAh less…
So I am searching for a nice charger which is suitable for AAA.
