Originally posted by Apapukas Some advantages belong to AA's too:
1. Eneloops hold the charge exceptionally well too.
4. Memory issues with the AA are a thing of the past.
9. Eneloops can live for up to 1.5k charges.
Unique advantages:
1. Safer.
2. Cheaper.
3. Can be bought at pretty much any shop in the world.
4. A larger variety to choose from, there is 2000/2500/... etc mAh types of AA's.
Yeah, I just stated the pros and cons of li-ion as a tech, not comparing them to eneloops.
But if you want some comparison in the points you brought up:
1. Li-Ion still hold charge better. Though for most uses the differances are negligable.
4. For Li-Ion there's always that advantage, for AA's it depends on the type used.
9. Eneloop cells don't die as sudden as Li-Ion and will therefore have a longer usage period.
1. They are safer in use and when transported but pose a bigger environmental and health risk when manufactured and disposed.
2. Cheaper per capacity yes.
3. Not at all as common here in Sweden.
4. The Li-Ion cells are also available in different forms. But as they ara supercharged at 3.7V they aren't available in standard sizes, simply for safety.
The main advantage for Li-Ions compared to Eneloops for most most consumer electronics is that the pack more power per weight and have a longer voltage peak before they drop when discharged. This helps making things more stable even though you can compensate a lot when designing the electronics. The higher voltage they provide per weight leads to a higher effectivity in the circuit board while keeping weight down.
