Test / Review: Keeppower 14500 800mAh (Black)

Considering 14500ā€™s are used in single-cell way 99% of the time you can use unprotected cell - which you can get in various places.

e.g. here: http://www.orbtronic.com/batteries-chargers/14500-sanyo-3.7v-840mah-li-ion-rechargeable-battery-cell-aa-size/

And considering that most single 14500 lights has a boost converter (So that they also can work with AA batteries) that will drain the battery to below 0.8 volt, the unprotected cell is a bad ide in most lights.

Oh crap, I totally forgot about that. Thanks for reminding! Indeed, 14500-light with a boost converter would be quite unsafe to use with unprotected cells.

I want protected ones so I dont drain them too low.

Any idea if they are available in singles or pairs HKJ?

Sorry, but no.

I know itā€™s months later, but for reference I found these on an Australian ebay listing:
http://www.ebay.com.au/itm/2x-Protected-Sanyo-Panasonic-UR14500P-800mAh-3-7V-Rechargeable-Lithium-battery-/280880529849
I bought a pair and theyā€™re labelled Keeppower.

Weā€™ll have them soon too :slight_smile: They test extremely well, and rival the Nitecore 14500 which is our in-house king now.

Well, tested them and while they perform admirably, they are just too long to be considered. The lower capacity version is shorter but still canā€™t dethrone the Nitecore ā€” and to a lesser degree the AW.

Hey HKJ
I would like to ask you if you heard anything about the Keeppower DLG protected 14500 800mAh? how does it compare to the Sanyo cell?

Not yet.

KumaBear has talked about sending a couple of DLG batteries to me for test, so there is a good probability that I will be testing them.

The next 14500 I will publish a test for is probably the Efest IMR cells.

Thanks for the clarification bro!
I guess they will be one of the best budget batteries for the price KumaBear is offering. Ill get a set to replace my 14500 Trustfire Flames.
Will be looking forward to see your latest findings 8)
keep up the great work :beer:

at almost 53mm arenā€™t they too long for certain lights?

It will be that, but remember that the light must be made for LiIon, before you can use this battery. It has the voltage of 3 NiMH in series!

hi henrik, yes iā€™ll be using them for Quarks and SC52.

the zebra ZL584 is just 52mm and is already protruding out of the Quarkā€™s body tube slightly. i noticed that the ZL584 has a low-profile nipple

the keeppower seems to have a taller nipple

They are waay too long for Nitecore D10. I have to keep using my old Trustfires.

The KeepPower 14500s we carry were never advertised as Sanyo, and they are listed on our website as having a DLG ICR14500 internal cell. A Sanyo version does exist but we did not claim that our version is Sanyo.

a sanyo BARE 14500 is already 49.4mm long :wink:

I guess we wonā€™t know for sure where those cells come from:

Would it be possible to update this review?

ā€œConclusion

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

There is not much point in updating this review, I will prefer to get a new battery from Keeppower with the new marking.
