Test/Review of Keeppower 18650 3100mAh (Black)

[CM2010]

I just got 6 with tracking for $63.

 

[justanotherguy]

cells showed up yesterday, 9 days, impressed!

hmmm ...mine havent show up yet...I paid on 8/03 too....sigh

I bid on 5 pairs for $100 and it was accepted.

These look like very good batteries, but for owners of the NiteCore TM11 'Tiny Monster' be aware that these 69.7mm tall batteries will not fit.

I plan to use my collection of Eagletac 18650 3100mAh batteries for the NiteCore TM11. These new KeepPower 3100mAh should fit all my other lights.

Thank you HKJ for all your information and help. :thumbsup:

Mine took 5 weeks to arrive, but they are great batteries, worth the wait.

 

[veedo]

[tobrien]

I live on the west coast USA and I have tracked my new batteries and they left China a few hours ago; expeced by shipper to arrive by 9/12/12.

 

[CM2010]

Mine turned up today, 17 days from ordering.

 

[sidecross]

[justanotherguy]

looking forward to your reply.
thanks

Best Regards! Bill

Just had an offer accepted almost immediately for 2 pair, four cells total, of the unprotected Panasonic 3100 mAH for $16.00 a pair instead of $17.50. Add $2.00 shipping and that's $34.00 for four cells. Not bad!

I looked at HKJ's comparator and it looks like the sanyo 2600 red is one of the best batteries out there in terms if keeping a higher voltage for longer then the rest except for imr's ,panasonic 2250 and lg pink 3000 mah and 2800 at 4.30 votls . I have the xtar 18700 2600 mah which I think uses the sanyo 2600 mah and looking at the charts the sanyo 18650 out performs the xtar voltage wise .

Yep! That's right. This ebay seller "doingoutdoor" is selling the red sanyo 2600's for $12.50 a pair plus two bucks shipping. If you could get them to accept a "Best offer" of say, $ 11.00 a pair you could get a pair of sanyo 2600's for only $13.00 shipped! Intl-outdoors couldn't compete against a price that low! Even the list price is a steal though. I wonder if folks realize that price is for a pair of cells. Better hurry though, the listing says "4 available / 10 sold".

***UPDATE*** Just had an offer accepted for four sanyo 2600's at $11.00 a pair. With $2.00 shipping that works out to six bucks a cell. I'm liking this seller!

So after getting these I wanted to know the difference...between a new top rated cell and my used(unknown amount) Redilast 2900 and an ultrafire2600

I started an sc600 and sc600w this morning on the redilast 2900 and a KP3100. about 5:15 am on Medium: M1 65Lm (18hrs)
When I got home at 4:45 pm the redilast was already out, wife said it happened recently...I got home from dinner this evening and
now at 10:15 pm the KP3100 still has the sc600w lit.....

pretty nice , though I dont know if the cool vs warm tint makes a difference.......??
Dont have the UF2600 at home to play with. Doubt I want to really.

Runtimes are tested using Panasonic NCR18650 (2900mAH) batteries. Light output are out the front (OTF) values. All levels are current regulated.

Ok with 3100's I expect then 7% more energy/runtime? Another 1-1.25 hours.....? I wont be up then!

Gutted, for some reason the guy on ebay won't ship to the UK anymore.

 

[Quest4fire]

O.K. I'm officially impressed. Ebay seller doingoutdoor got my eight cells (Four Panasonic, four Sanyo) from China to my doorstep in the middle of the US in 11 days! It will take a while to charge them up and discharge them for a capacity check, but they appear to be the real McCoy. I don't think there will be any surprises.

Quest out...

 

[justanotherguy]

Now shipping has jacked up to $20.....!

 

[justanotherguy]

Ebay seller Doingoutdoor is NARU on ebay...no longer a registered user....
argh
