4R25 Lantern Battery

6 Volt lantern battery yours just failed again? This STL will let you run your lantern off four AA batteries. You will need a length of solid copper wire the hole and track is for 2.5mm wire such as household wiring, a couple springs (I used old biro ones) and four AA batteries. Bend the wire to go into the hole either side (from the bottom). Push the wire into the slot on the bottom, you might need to add a small bump for the battery to make a connection, The wire comes out of the top, fold it over and cutt off the extra. Load two batteries in each hole with a small spring between each battery making sure you have them connected in series so the +ve is the centre top and the other top hole shows a -ve. You should then be able to add it to the torch and you are fine to go. It might not last as long as previous but you should be fine.
