Ultrafire batteries OK?

Can I use this battery in my grand?

Ultrafire 18650 2400mah ULTRAFIRE-18650-2400-PTD 1 7.95
BUTTON TOP Protected
Rechargeable Lithium
Battery Li-Ion UF18650

Those batteries might fit in the Grand. But they are NOT the recommended batteries.
What you must be careful for is the battery compressing the spring.
The spring will collapse in case of a short and the battery can drop away from the firing mechanism.
If the battery is so long that it compresses the spring then you bypass that safety feature.
You could melt your firing button and your Grand if you had a short.

Hi Bobdog,

I just got a great deal on the AW IMR 18650 here ($9.95 each as opposed to $11.99 or $12.99 or even $14 bucks on other sites).

AW IMR 18650 1600mah - IkenVape Store

Enjoy in good health

I've used both a trustfire and an ultrafire in my grand and the flame wrapped one is a little snug but doesn't compress the spring too much. I swap them out with aw batteries regularly.

There not the recommended battery but they will work in a pinch . Many of use used them for a long time before the imrs became popular .Pick up some aw imr batteries when you get a chance there definitely a better battery and safer

I guess I should have said that they are only used if all of my aws are dead.
