Best place for 18650 Li-ion batteries

[Dirac]

So I got my lasers in today from laserlands. But I was a moron and didn't order batteries from them (figured incorrectly that they would be supplied since they were in the photos of the product.)

Thus I drove up to the specialty battery store down the road and asked if they carried the 18650 li ion cell...no luck (they had no idea what it was). Same answer at radio shack.

So where would be the best place to pick these up quickly? Having them laying around is killing me and I really dont want to wait another 3 weeks to order them from china.

P.S. The 405nm blue (20mW 2 in 1 Blue Violet Purple Laser Pointer with a Star Cap - $23.00 : Laserlands) works great and clocked in at ~23-25 mw. SO up to spec which has me hopeful for the rest of the fun.

I did (almost) the same thing when I ordered my portable... This place is in California and they'll have FedEx get it to you quickly: Rechargeable Batteries & Battery Chargers - LG Chem Li-Ion 18650 3.7V 2600 mAh Rechargeable Battery

Dirac;

I have Panasonic #18650 batteries and chargers in stock.

Most chinese lithiums I have tested are of poor quality.

I have several Tenergy batteries and though I don't have a meter to test the capacity of these batteries, based on my estimates, they are performing roughly correctly.

I have used BatteryJunction before. They're just a few states over, so the shipping is extremely fast:
BatteryJunction.com Batteries, Battery Chargers, Flashlights, Solar Products & more!

the flashlight and RC hobby enthusiasts seem to have the best batteries, if any of you are members of other forums, give 'em a shot. Personally, I just get used 18650's, recycle the ones I don't deem worthy, and keep the rest 'Cause hey, free batteries!

Get some batteries from Larry!
I own a few and each charge lasts much longer than the Chinese "TrustFire" 18650s I own. And they are protected!

 

[BShanahan14rulz]

Wow, Larry's got some good cells! I have the old-style samsungs, probably LiCo chemistry. Larry, do you know what chemistry those use? I know the CGR in CGR18650 denotes something, I just can't find that chart that I had seen about the Li-Ion Prefixes.

Thanks for the battery endorsement, RA.

The Panasonic #18650 2400mah batteries are Lithium Cobalt Oxide types.

Here is a PDF on these cells:

Damn Larry, too bad you don't have any 10440's that had PCB. I hate these cheap Chinese Li-Ions :'(

Do you need a special charger for higher quality batteries you sell Larry, or will the typical 18650 charger work?

 

[LarryDFW]

Tech Junkie;

The standard #18650 charger will work just fine.

I have tested a few for charging voltage,
and selected one that does a good job.

A photo of it is in my signature link.

Cool Larry, thank you.

Hi， guys
Sorry about the inconvenience.
we usually do not include battery into a laser product package to reduce the risk of confiscation by customs or post office. you know batteries are usually not allowed by shippers or customs.
so i suggest buy battery locally or domestically
BTW, laserlands laser pens are over 90% over spec. there is none 5mw laser pointer pen actually to be honest

Yeah, I recently shipped two lasers with batteries to UK and they told me I can only ship batteries via surface mail in the post office.
You ship airmail, right, Merry?

Here is another good charger for the 18650 cell's, it' rated at 1000ma so it will get your cell's back to the top faster ! if you need one drop me a line each one comes with a new hand made laser or laser kit :tinfoil:

The Absolute best place for 18650s is to take a friend's laptop, remove the battery, get a hammer and a screwdriver.....you see where this is going, of course you do! Towards high quality Panasonic cells!!!
