The battery has no problem keeping the rated capacity, even the 2A trace is very close to rated capacity.

[size=+3]Conclusion[/size]

There is not much to say about this battery, with a Sanyo cell inside and a protection at around 3A, I will call it a very good battery.



[size=+3]Notes and links[/size]

Keeppower is a OEM manufacturer, i.e. many of the batteries they produce is sold with other names on them.

The batteries was supplied by Keeppower for review.

They sound very reliable. I'd like to buy some, but I guess they're not for sale under the Keeppower name? I guess I'm not understanding why they provide cells for evaluation... that perhaps are only available under one of the other names they produce for?

It is old good Sanyo. Most of their cells are top performers.

Thank you HKJ

Great review thanks, i sent a message to the ebayer who sells the Keeppower 18650's
in the hope they maybe were going to sell the 14500's, but they replied saying no.

It's such a tease to submit these for review and then not sell them.

Great minds:). I asked about the 16340 cells, and was told the same thing.

I know they're unprotected, but Orbtronics is selling the Sanyo 840 mHa 14500 cells for $8 a pop and if you buy 4, you get 10% off and shipping is gratis.

They work well in my single cell Xeno E03.

Try asking keeppower about it (I do not know what the answer will be).

doingoutdoor has these on their site now in a 4-pack for just over $20 now which looks like a great deal IMO (for four cells)

Good price and if you need you can buy less than four pcs. My batteries shipping time was 4days! This is my record with normal airmail (normally 8-10 days). They use singapore post.

btw 16340 not working with Armytek Partner C1, but perfect for Olight S10.

hi henrik, yes i’ll be using them for Quarks and SC52.
the zebra ZL584 is just 52mm and is already protruding out of the Quark’s body tube slightly. i noticed that the ZL584 has a low-profile nipple
the keeppower seems to have a taller nipple

I received a pair of these a few weeks ago from Wallbuys. I'd read a comment that Keeppower will use both Sanyo and DLG ICR14500 cells, so I sent them an email asking if there was any way of telling which I'd received.

Their answer was simple - Keeppower 14500 batteries labelled ""Cell&IC made in Japan" means the cell is Sanyo UR14500P. If there is only "IC made in Japan", that means the cell is DLG ICR14500. Oddly enough the photo on the Wallbuys site shows that they now ship DLG cells, but the ones I were sent (which took 40 days to get to me because of the shipping delays from China) were Sanyo.

I just noticed in your photos in the review, HKJ, that your cells are labelled "IC Made in China". I know your review is over 18 months old, so I just wonder if it is only relatively recently that Keeppower changed their labelling to accommodate the fact that they use more than one cell for their 14500 batteries?

I just received 2 of the Keeppower 14500 batteries and tried them in a ZL SC52, Eagletac D25A clicky, and 47's QB2A (1xAA body). They worked in the ZL but I felt like I was putting more pressure on the tailcap spring than I care for. Didn't work at all in the 47's. In the Eagletac, only allowed the tailcap on far enough to access group 1 output but would not tighten enough for group 2 (turbo and strobe modes). I'm a little disappointed as it seems that these were going to be great batteries. I just have no lights in which to use them. Anyone have any recommendations on lights that these definitely fit? If so I'll just have to buy a new light. What a shame. :D

My Keeppower 14500 (840mAh) suddenly stopped working in my Zebralight SC52. Tried in my H52w and charger but still nothing. Charger does not charger it at all. I have been using it with my SC52 and D25A Ti(2014) before. It is only roughly two months old. Then I tested it with my D25A Ti and it worked but only with D25A. I was wondering if it somehow got damaged when used with the D25A due to overtightening. As some of you guys know the Keeppower 14500 does not fit entirely in the D25A.

I got first hand experience that these cells are not robust or maybe I am just unlucky. :sigh:

I wouldn't be surprised if these cells stopped working due to physical damage to the protection circuit from excessive spring pressure. When I recently ordered some unprotected 14500URs from Orbtronic, they sent me protected cells instead. I figured I would try them. But I noticed that the negative terminal was practically flush with the end of the tube! This would almost certainly bind the tail spring, possibly damaging both the battery and the light itself. I promptly sent them back and asked that I get the unprotected cells I ordered in the first place. The unprotected cells fit and work like a charm!
