350 flashlight. Not working. how do you change the battery?

Hi,

please attempt to twist the top or the bottom of the flashlight off in order to open it and the batteries that you've mentioned. Otherwise, you can drop buy your local geeksquad/bestbuy to have a tech do the battery replacement for you.

Thank you.

the bulbs could be bad, the batteries could be bad, you could have replaced with incompatible batteries or have the wrong orientation. did you realign the compartment to make contact ? often the spot where the batteries go have a wire or metal that connects to another wire or metal when you replace the battery compartment- maybe that metal or wire is not aligned correctly or touching like it should. This was not a question but more of a generalized problem that could have so many solutions. Im not sure more information would have.
good luck

make you request to manufacturer

Put the batteries in positive (+) end first, continue putting the batteries in where the positive touches the negative (-) end of the previous battery.

To my knowledge all you have to do is screw off the lid at the back and replace the batteries some of these flashlights comes with a charger some doesn't

Maureen, Coleman Graphite Flashlight replace batteries. Remove bottom cap, it will be on tight, if you do not have good strength in your hands use a pair of pliers or channel locks. Check the attached links,instruction and guides, Good luck

How to change the batteries in Mag Lite

The flashlight uses 1 AA battery. My guess, you should only have to unscrew the end cap. If you finds it very hard to unscrew the end cap off, it could be from the battery has explode and swollen. MAYBE - I see this happen in my daughters MAG flashlight. DO not keep your flashlight in the car with the batteries installed. The amount of heat in the cars can ruin the batteries in the flashlight.

It's probably bethind the sliding door where you make settings adjustments. On the 700 model (digital), you have slide the door further down past the stop. You have to pull hard. But slide the door first to the normal stop and look under it with a flashlight...you should be able to see the battery it that's where it is.

If it uses AA batteries there is likely a spare bulb in a keeper below the spring. HTH

Unless the bulb is burned out or you are putting the batteries in wrong there is not much that can go wrong with a flashlight.
