Question Sure Fire

I have an old surefire 8x flashlight that is over 15yrs old have replaced the battery in it a couple of times other than that it is all original. I would like to know if there is a way to make a replacement battery or have a replacement battery made? A battery stick or multiple batteries are fine but most likely if it is multiples I will need a charger also. i a m a noob to building flashlights but I do understand circuitry and fell that it should be a simple task just dont have the background for part acquisitions. I have spoke with surefire and they have discontinued the battery the charger and the light and have made all direct replacement parts obsolete.

Any asssitance would be a great help and any guidance is appreciated.

This answer is as old as it gets, but perhaps still of use to you: http://www.candlepowerforums.com/vb...wice-the-Run-Time-and-Brighter%85-B90-Upgrade

This is most likely the best upgrade path you have for your flashlight. The product is not still available to my knowledge but there shouldn't be much preventing you from getting your hands on the necessary components.

I have not purchased one of these, but they claim that it will work. If the photo is accurate, I don't think that it will work. The B90 has to have both poles on the top to work. They look like the Stinger batteries.

edit: I just sent them an email for clarification. I have been looking for B90 replacements for a while.

I have ordered two of these and will be receiving them this week. I have an 8NX that I will be trying these in. Actually I ordered them not closely looking at the photos, It does look as if there is no negative ring. I hope they work, but if not I will send them back. I will post a note up when they arrive.

Thank you that be great I really like the light and it has worked well for many years, and it has many years left if I can just get a battery.

The next issue will be replacing the lamp assembly. I have a spare, but after that I am SOL.

I received an email response from them as they claim that photo is accurate. I am interested in whether it will work as a replacement for the Surefire rechargeables

Just want to let folks know the batteries I ordered as B90 replacements, DO NOT WORK. There is no negative contact for the lamp spring. I have decided to abandon this search. The SF still runs about 25 minutes on the one survivng battery. When it or the lamp goes poof, maybe I will try some more complex mod. I have enough in the batteries now that I could have bought a new light with twice the lumen and none of the battery issues. Other than my eneloops, I think Im done with rechargeables.

I think that the Stinger batteries would work if one were to solder a 9 volt nipple to the top of the battery.

They do work in the light, but not with the charger. At least that is my understanding.
