Thread: Simple battery question about Jetbeam E3s

    Default Simple battery question about Jetbeam E3s

    Eventually, my stupid day one questions will stop the more I learn, I assure you. Lol

    I've searched and just don't find much on the Jetbeam E3s on here. Not even a review.

    The specs of the light say 155ish lumens on a "standard" AA battery. Assuming that's a regular alkaline.

    Is it safe to use any sort of rechargeable in here? I know not a 10440s or anything crazy. But I'm just not sure what's safe when it comes to the different type of AA's out there that are rechargeable.

    Any help and info would be greatly appreciated.

    Alkalines and NiMH rechargeables as you would find in a store are essentially always interchangeable; in fact NiMH cells don't experience as much voltage sag when driven hard as alkalines do, so you'll find they provide more output over a longer period of time, with much better regulation.

    There's a lengthy E3 review here.

    Thank you for the link. Question, any recommendations on which NiMH batteries would be preferred? Just simple Duracell or Energizers from Walmart, etc.?

    Sanyo Eneloops are the perennial best-tested brand; if you happen to be a member at Costco, they sometimes run good deals on starter kits there, otherwise any of your local big box stores.

    So I just need the regular 2nd gen Eneloops right? Not the 'XX' offerings?

    XXs will give you roughly 25% more runtime, however they only charge ~500 times, standard Eneloops are rated for 1500 recharges. So if you use your light constantly and really need a bit more runtime, as in a professional application, go with the XXs, otherwise the standard longer-lasting Eneloops are a better deal.

    Also, if this light is going to be left in a car (the E3 is my current favorite in-car light because of it's durability and simplicity), skip rechargeables altogether and use Energizer Lithiums, which can handle the temperature extremes the interior of your car experiences.

    This will be a new EDC for me to replace my Microstream. (Purchased the EX11 clip).

    So i think I'll just get the regular Eneloops.

    It will be quite a change for you mass-wise; the Jetbeam weighs over three times more than the Streamlight, but you can't beat stainless steel durability. Hope you enjoy your serious new tool.

    I think I will.

    I had another question.. I'm reading a lot about how complicated it is to manage and upkeep rechargeables... And a lot of people are saying the MaHa C-9000 charger is the best or highly recommended. I already spent $50ish on my Pila charger for my Jetbeam 18650's and it's worked flawlessly for about a year now. Will the supplied charger for the Eneloops work and not give me any issues? I guess regarding overcharging, auto-switch to trickle charging after a full charge, thermo-switch protection, etc.

    The basic kit charger doesn't really have any features, you just put your batteries in and wait for the lights to signal completion; this is perfectly fine for everyday use, just make sure that if the instructions tell you to charge in pairs that you do so - most basic chargers can't charge cells singly.

    This is what I bought. I hope it's the most newest Eneloops. http://www.amazon.com/gp/aw/d/B004RP...0017320&sr=8-2

    There was another set but it had orange on the packaging and looked to me like the older Eneloops kit. Correct me if I'm wrong?

    I'm not sure how to tell by the packaging, but if you look on the individual cells, the newer version will have the image of a crown on them. Either way, your kit will give you many years of use.

    Well I'll find out Saturday when they get delivered. Along with my light

    If the threads or o-ring on your light looks/feels dry, be sure to read up on proper cleaning and lube procedure. And remember that the o-ring is like wiper blades on a car, it's meant to be replaced over time or if anything goes wrong with it. With just a bit of care, you'll have the option of passing on your new light to your grandkids one day..

    I know this is about my E3s but what is a good light with a lot of throw, lumens, on RCR123 or one 18650 that is about 5" long or so for under $125. I have a coupon code to take 15% off so keep that in mind too

    If you can fudge your length and price requirement a bit, a Thrunite Scorpion V2 with the optional Turbohead would come closest to your requirements off the top of my head, it's just over 6" and $160 for both.

    Is that something that can be had at light junction?

    Yep, right here, but they don't sell the Turbohead; BatJunc has it in stock. You might try the light alone and see how it fits your needs, 750 lumens goes a long way..

    Hmm very tempting. I can have the light for like $109. And the head for the $30... But idk

    Here's another contender, this one is already a thrower and has the option of an extender tube to make it brighter.

    What are your thoughts about the Zebra SC600? I just picked one up

    The SC600 is one of those must-have lights that define the time; everyone will remember late 2011-early 2012 as the SC600 era. It's definitely not a thrower, but when you need to light up your entire backyard with a light that fits in your pocket, there's no other..

    I have two Jetbeam 18650's for my M1Xm.. And charge them in the Pila smart charger from BOG. I would like to get a dedicated cell for my new SC600 in the mail starting tomorrow. Having this charger, what would be the best cell to charge in this charger and use in the SC600?

    The AW protected cell is the highest-rated Li-ion out there, and he just released the 3100mAh version..

    Halo, can I use my battery right when I get it or is it best to charge it first?

    They usually ship charged, check the voltage first, it should be around 4 volts; if that's the case, it's ready to go. If it's under 3.6 volts, charge first.
