what are the pros and cons on both of these? i tend to prefer using energizer lithium advanced in my lights, and not sure if its the right choice
i remember someone had answered this question for me once before, but it was in a separate thread about something different.
thanks guys, i know someone here knows all the ins and outs of these
I’ll give it a shot, but you probably know more about them than I do. 
| Eneloops | Lithium Primaries |
| Rechargable | Non-rechargable |
| Lower capacity (2,000-2,500mAh) | Highest capacity (3,200mAh) |
| Lower voltage 1.2V | Higher voltage 1.5V |
| At my country, they’re priced about the same. | At my country, they’re priced about the same. |
| Higher discharge rates | High discharge rates |
| Somewhat resistant to cold | More resistant to cold |
| Pre-charged | Ready to use |

| Low Self Discharge (but still loses its charge) | Long shelf life (10+ years) |
Anything else? :bigsmile:
So I personally wouldn’t use Lithium Primaries due to its price, especially when a pair costs over $10 here. :_(
good start! i knew most of this already, but some may have not
i get my energizers from a local discount store that almost always has stock for $2 a pair. thing i like about them is they seem to last forever in my lights, when i use my duraloops, they seem to die of rather quickly, a lot faster than the 33% difference in mah it seems
i thought i remembered someone say that there is more voltage sag with the lithium primaries and that they can not provide the same amperage as eneloops... but i can not verify that as a fact
thanks for the nice chart though!will be handy for some im sure
Oh man, $2 a pair sure is a game changer.
If that’s the case, I would keep both, as lithium primaries have great shelf life.
So I would put them in lights that I don’t use often (and they don’t leak either) because they will be ready to go anytime.
Lights you use often I would put Eneloops in them because they can be recharged over 500-1000 times.
Sorry I couldn’t be of much help.
plenty of help
ive got 2 energizer lights i keep loaded with primaries, and my ea4... so thats 8 cells total
i have had my ea4w since early feb, and its still reading 6v on the light. i have used it quite a bit, but most of the time either low or med
im just curious if used in something like the ea4 if im getting a considerable difference in output that i would get with eneloops/duraloops. but all of the info would be helpful to the thread i think
Heavy frequent use > rechargeable
Rare, occasional use > primary, unless you simply like ‘burning’ money.
In between…….you determine your hassle vs. value equation.
I prefer the eneloop for my daily use, is to save money.
Often primary Lithium will have better performance

If weight is one factor, remember that a eneloop XX weighs twice a primary Lithium.
