Feeding a Fenix

I am going to be acquiring a Fenix L1P and a L2P.

I know that they run off 1 or AA batteries but what kinds can they digest?

What brands, models have you used that seems to work the best?

Are they able to use the Energizer Lithium Batteries?

I am not looking for rechargeable's at this time, as my lights don't get enough use.

Any help would be appreciated

my l1p works great with lithiums, nice output. l2p should be fine as well.

Pretty much any brand AA size battery works fine with Energizer Lithiums being the best. Don't use non-alkaline heavy duty batteries as they die in a few minutes. Also don't use rechargeable lithium ions with 3.7V ratings.

I know you don't want rechargeables but they are at the same level as the lithium for these lights. Just take a look at the L2P:

2AA Alkaline: 2h regulation
2AA NiMH/Lithium: >4h regulation

Take a look at the AA-Sanyo Eneloop cells. Low self-discharge, so you can store the light for a long time without using.
They will save you a lot of money over the time.

Your best bet, if you, like me, really like the Energizer L91 Lithium primary batteries, might be to get the L2P with an extra L1P body:

You can feed it 2xAA alkaline or L91, and it runs better on a single L91 with the L2P head on the L1P body than does a regular L1P, running for 3 hours! It will not drain every last bit of energy when running on a single alkaline, but it will still last about 90 minutes.

Just check the AA is not a tight fit when putting into Fenix.

Difficult to get out.

And don't let alkaline AA run down, it may expand, or leak.

Yes, any quality battery works fine. Those Energizer Lithiums are great!

How much does an AA lithium cost? $1.50 to $2.00? Costco's alkaline AAs sold in packs of 48 come out to about 20 cents a piece . One of the main reasons I was attracted to the L2p is its great performance with AA alkalines.


But for those who have the extra L1P body for the L2P head, I agree with europium that it might be a good idea to run a single L91 with the L2p head.

You just gotta love those Kirkland AA batteries. They work like a charm in the Fenix AA lights. Dittos on the L2P head on the L1P body with L91s.

Yup.. +1 here those cosco kirklands work great & cheap

I like Costco a lot, but it can be a very dangerous place for your pocketbook if you are not careful

I recommend NiMH rechargeable especially in the L1p. Lithiums work great but they are expensive. Alkalines work, but not nearly as well. Runtime is shorter in the L2p and brightness suffers after a few minutes in the L1p. NiMH is also much more environmentally friendly. Use Eneloops if you're concerned about self-discharge. I generally don't worry about that with my own L1p, I just charge up the cell every so often.

The one situation where lithium really beats NiMH in these lights is cold weather. Otherwise lithium runs the light a little bit longer and brighter but not enough for the expense to usually be worth it. That assumes you want the light for regular use. If you want to tuck it away for emergencies, lithium will have the longest runtime and storage life.

Hands down, NiMh is the best battery choice for the Fenix. The batteries are relatively cheap (around $1 each or less) and will take 1000 charges.

Lithiums are great for a glove box light that won't get used in years, but for everyday use, NiMh is the clear winner.

Energizer NiMH rechargeable batteries have worked well in all of mine,
