Here's how I've been repairing flashlights. I thought some of you might want to see how it's done so you can do it for yourself. Also, if you want yours fixed and don't want to do it yourself, send it to me with $10.00 to cover the cost of the two batteries, the bulb, and return shipping. I'd also be interested in buying your non-working flashlights....batteries can be bought here for $1.99 each plus shipping: http://www.onlybatterypacks.com/showitem.asp?ItemID=11412 bulbs can be bought at radio shack for $1.79 plus taxFirst: here are the tools I useSoldersoldering ironwire brush for cleaning iron tipsmall flat screwdriverwiresomething for cutting wirewire splicerssuper glueNEXT: OPEN THE FLASHLIGHTgently pry the flashlight open with your small flathead screwdriver. i find it best to start at the top around where the bulb goeshere's a view of the flashlight opened:remove the internals:now you want to break the weld from the negative and positive terminals of the battery, again useing your screwdriver to pry it off.here's what you'll have after the battery is removed:now it's time to make room for the new batteries. take your wire cutters and make a few snips around the plastic ring that the old battery was. then break the plastic "tabs" by pressing them down. Be carefull not too take too much plastic off, check all the pictures before you do it because there are certain spots that need to remain.now for the batteries:i use superglue to hold them together, then i put some solder down on all the terminal so they'll be ready for the wires. after they're glued together and the solder is on, run one wire from the negative to the positive of the other battery. then put a wire on the remaining battery negative and positive terminals. in certain areas i glue the wire down to hold it in place (i showed that in the pics).
