Someone over on the SF discussion board reccomended the following for a fix to the B90 problem Surefire is having
I can get all the parts for a moderate price so I thought I might tey this in the few weeks. Whatta ya all think ? /ubbthreads/images/graemlins/confused.gif ?
Here's what you do:
--Buy a baggie of 9V terminals from Radio Shcak, costs about two bucks. Also buy a baggie of solder tape, and a small tube of solder flux (all available from RS). Hopefully, you already have a soldering iron, because they can be somewhat pricey for the higher watt models, but anyways...
--Remove the small tab from the 9V terminal, being careful not to damage it.
--With a bit of sandpaper or file, roughen up the bottom of the tab and the inner (positive) terminal of the battery stick, and then clean all surfaces to be soldered.
--Place a tiny bit of flux on the battery terminal, and then place a tiny square (just enough to cover the bottom of the tab to be soldered)of the solder tape onto the battery terminal. Place a tiny bit of flux on the tab, and then place the tab onto the solder tape (that's on the battery terminal).
--Apply heat to the tab, making sure it's centered on the battery tab. Also make sure not to melt the plastic spacer that surrounds the bettery.
--As the tab heats, the solder tape will melt, and theflux will allow it to flow, and prevent a possible "cold joint." Leave the iron on for a few seconds after the tape melts. Carefully remove the iron, and allow the parts to cool.
The finished battery will work with SF lights and chargers. Also should work with Straemlight lights and chargers.
