This battery pack works perfectly to convert a 3 D cell Maglite into a rechargeable unit that puts out 6 volts; enough to run the TerraLUX / Lightstar Corp. MiniStar31M-EX LED Conversion Kit for 4-6 D Cell MagLites. That's right; you do not need a 4 to 6 D cell Maglite to run this 1000 lumen LED head. The upgrade consisted of replacing the stock head with the minister 31 M-EX LED unit. The new battery pack is a simple drop-in, screw the tail cap back on and you are in business. All-in-all, this setup breathes new life into the old incandescent and makes it rechargeable too! What a difference in light output; I am happy with this purchase.

I bought this battery in March 2011 and believe it or not it is still going strong. I just wish they had more batteries like this for my other flashlights. This battery is awesome!

I used this to replace the failing battery in my Mag-Charger,fit was good and it took a quick charge

I have a 600LU drop-in in my Mag-charger and this battery last longer than the OEM, and it was cheaper! It can sit around for months and still have plenty of juice when I need it. Highly recommended.

Charged the battery and works really well so far. Your price was less than at a local store. Lot less.

Bought this battery from Battery Junction 3 years ago and still performs like a new one.

I use this battery in my Mag-Charger with 600 lumen Terralux module. It lasts for hours! Even when not in use, the battery retains its charge for months. Very impressed and much better than those made by Streamlight and Maglite.
