Screwdriver Battery

[Budweiser8Jr]

Okay, I have a question:

I was looking at buying a screwdriver, especially at the nice sale price. However, what kind of batteries does it take?

 

[rotten76]

The SDMKII takes an 18350.

Hi Budweiser8Jr

The Screwdriver MKII takes 900mAh, 3.7 Volts. Re-Chargeable Protected Lithium batteries.

Hi Budweiser8Jr

These batteries were specially made for the SD MKII


Screwdriver MKII-Spare Battery.

can i charge the screwdriver battery with this charger from dx?
TrustFire All-in-One Charger
it says that:
- 500mA charging current
- Charges 3.6V 10430, 10440, 14500, 16340, 17670, 18650, and CR123A lithium batteries

it would be great if this can be done

Sorry Miss Wicked, but I think that answer may confuse people.You may have stated the mAh & Volts correctly but that doesn't help people with choosing the correct size of battery. For instance, there are 14500 900mah 3.7volt rechargeable batteries & I doubt very much they would fit the SD MK11. I would think they would be too thin (OK not a major problem) & too long (A bigger problem).

From research, I believe that rotten76 is right & the SD MK11 takes a 18350 size battery.

I have that very same charger and it works perfectly.

 

[Miss Wicked]

Sorry if i confused anybody, just stating the description we have for the Screwdriver MKII batteries...

 

[Koman]

I think you can use other batteries for it as well...

 

[Budweiser8Jr]

Well I made the plunge and got the thing with some LR attys. All I can say is WOW. The combo is amazing, although I have noticed since the atty has broken in that I am drinking juice! Getting about 2 hits per drop and then I have to refill after about 10 hits total.

 

[Minna]

Oh yeah, these LR atties are thirsty little beasts! I've taken to using a drip tip with them and it works great.

 

[Budweiser8Jr]

It's worth it. I am going to try a 510 cartomizer on it soon. I heard those hold 40 drops.

I have tried the CR123a (aka 18350) Protected and unprotected. The unprotected kind of fits but is just a little to thin so it gets stuck, the protected one is to long..
Looks like I will have to try one of there's

 

[sktoris]

I have tried the CR123a (aka 18350)

But CR123a is 3v, not good for SD. 18350 is 3.7V 900 to 1200mAh

Can anyone tell me how long it takes to charge these darn things? I just got my screw driver today and started charging the battery at 4 central. It's now 8 and the red light is still on... dang

 

[boxhead]

well, i can say i don`t always wait for red light to turn green and still get a long uswe time out of them...you got a volt meter? if it reads over 3.7 use it...i get anywhere from 3.7 to 4.2 on a 16340 batt, and would think same on 18350 batt...

 

[tedward1555]

I don't have a volt meter but is it ok to try it? meaning is it unsafe to use if it's not fully charged or will it just not work well?
Thanks for the help.
Ed

 

[boxhead]

completly safe, most new batts wont care what charge their at...well if it has a PCB (protection circut board) the stop power at 2.75vdc and stops charging at 4.2vdc...it will work if the charge is between those two voltages. when you take off a charger before the led greens on, it may be so close any difference of the use time wont be noticeable untill the battery gets used and the nature of running these batts in a high drain applaction ( an atmozier) helps with batters sure death.

thats why some high drain batts are getting poplar. the chemeristy is better able to survive the cycle of e-cig onoffonoff...charge...onoffonoff...charge and they are more costly to buy, but if you want a battery that will have defined lifetime (say 600-900charges i am tired right now so that is a guess...sorry) get some. i have 4 unused batts for use when the 6 in use belly up, and 4 would give me time to get more...

Sorry typed to fast, DX sells a cr123 (16350) 3.7v that is 900mah real world is aroung 500mah.
I just put some heat shrink around them to make it thicker.
