Recommend me CR2 batteries please!

I just purchased the Quark mini CR2 because locally I could find these batteries for $1 a piece. However, I cannot find them anymore. I used to have rechargeables from DX for my red laser but sold them.

Which batteries would you recommend I get to run in this light? Would the rechargeables work? If so which ones (and which charger to go with)?

Thanks in advance!

Mike

Not very cheap but not overly expensive for a brand battery.

Those look like these:

you should also get the rechargeable ones: http://www.dealextreme.com/details.dx/sku.932 with the 3v charger: http://www.dealextreme.com/details.dx/sku.2031

Anyone has a Quark mini CR2 and an ITP EOS A3? How do you compare them? (any pics?)

in product description, 4seven says: " do not use rechargable CR2 batteries" for quark mini CR2 edition. So, is there anyone tried rechargable CR2's with it? what problems may occur using with rechargables? Both, 4sevens CR2 batteries and below one is 3v.

This is very belated, but I found this in a related search, and figure others will find this in the future looking for the answer to the last unanswered question, which question still holds relevance.

While the owner of 4sevens on CPF called using [higher-voltage] rechargeables in the quark mini's "crazy", I've had no problem, and I disagree that it's crazy on short runtimes. Same LED and voltage as you'd have in any other flashlight, just lower maximum output the battery can easily do (same chemistry and voltage though), and less heatsinking ability. But plenty of crappy bigger LED lights out there come with essentially "no" heatsinking. 4sevens paid attention to heatsinking and that is their main concern when they warn you away, assuming someone out there is gonna let a batt bleed out on high. I also like that the Quark MiNi starts on Low, so even if it did turn on in your pocket, there's no reasonable chance it'd get to High.

At first I bought a pair of "3.0V" (they are really LiFePO4) on dealextreme for cheap--I believe the ones linked above. While not approved for that type of battery, I used my much-loved "universal" charger with a few DX mini rare earth magnets to make them fit. It overcharged them to 3.8V instead of the recommended 3.6V top end, but they worked.

I knew the light could have more output. I finally located a true 4.2V li-ion (LiCo) cell from LightHound. It did produce more light output. I was finally satisfied. I usually use the MiNi on low or medium anyway, and only use High for short bursts when needed. The Lighthound blue unbranded cell is unprotected an IMO does not need to be protected. It is labeled as a 15266, 300mAH, current price $4.55. This is the only 4.2V CR2-sized cell I know of, but luckily, it was the last one I needed. No problems. Even considering I only use it normally seconds at a time, the battery lasts surprisingly long. After maybe 6 months, it's down to 3.6V, and I charge it.

I got my MiNi for quick things like fumbling with keys, checking the mailbox, and doing a quick checking of the engine compartment for funny noises (where the high available power of the Li-Ion comes in handy). I try to have a bigger flashlight around, not for more light but simply runtime if needed. I started out with the idea to carry a P60 host in my carry bag and in each car if I forgot, but I'm finding an SK68 with a 14500 works satisfyingly well, is handily smaller, and AA primaries as emergency glove-box backups are cheap easy safe and better at handling car heat than Li-Ion.

I use my trusty (much-maligned at CPF) "Universal Chargers" also for the 15266. Like these (Manafont has 2 at different prices which look similar or identical):

$3.78 HUANGAO - Single Lithium Battery Charger for 1.2/3.6/9V Battery(100V~240V)

$4.79 Universal Smart Quick Charger(100~240VAC)

Very slow charger, which I like, good for small cells especially. All mine slightly undercharge at under 4.20V but over 4.10V, which is safe and good for battery longevity. Takes all night to charge an 18650 from 3.6V.

Again you'd need a mini-magnet or something to bridge the gap. Lighthound sells a single strong battery for this purpose which I got, and it works fine,

Magnetic Spacer for Charging CR2 or 14250 Battery ($0.95)

but so does a short stack of narrow neo's from DX.

The Panasonics work great with my 2 (yes I have two, lol) Quark CR2s.

As far as I know you won't be able to turn it on OR fry it with rechargables. It's a 4sevens thing...

DX was the best deal I could find on primary CR2's, but I found that wasteful. Rechargeables weren't a whole lot more, I mean per battery. The DX 3.0V rechargeables two-pack is $3-something, almost a head-shakingly low price. They are lower voltage than standard lithium-ion when not overcharged but a little higher than primaries. They are not really 3.0 volts, that's nominal, and misleading IMO.

"As far as [you] know." Have you ever tried it? I personally have use rechargeables since depleting my second primary, close to 2 years now? It turns on just fine. And you probably could damage it if you left it on high for a long time. That's why they say just don't do it at all. No other reason that I can tell. But that would only be the user's fault. It will not happen by accident, like can happen with other flashlights, notably the Trustfire Z1 right-angle CR123.
