Why doesn't a standard lithium battery work as a back-up or replacement for this light? I bought two back-ups for long night rides and they don't work

What i experience it was that battery it was to strong for the light ball And it burns it.

Sorry, I have never needed to replace my battery. I imagine if you search the replacement battery number on Amazon or at Dorcys web site you should be able to find one? My light has never gone dead! so I have never needed a spare 1 charge lasts months! unless you accidentally leave it on all night! sorry I can't help more... good luckRich

I have bought a dozen of these flashlights over the last five years. Initially, they all had the same problem, the switch would only work if held part way on. The answer below this from R. Hennigh about a loose retaining nut is worth a shot, but for all twelve of mine, here's what I had to do, and what I'd recommend you try first. Unscrew the head and tailcaps of the flashlight and remove the battery. Hold the body tube up towards a window or a lamp...can you see through the tube? If not, take a long drift pin, a long dowel rod, anything that can take a good whack and not break...insert into the body tube from the tail (switch) end...when it contacts the plastic disc obstruction in the body tube, hold the tube tightly, and whack the rod with a hammer...HARD! When you dislodge the black plastic disc with the little brass colored rivet in its center, THROW IT AWAY! It serves no purpose, and stops the flashlight from working. Once removed, reassemble the head-end, re-insert the battery, and twist the switch cap back on...it should work fine now. Those caps were supposed to ensure the battery was inserted the correct way...the rivet is slightly indented on the tube side, and slightly proud on the head side. This would stop the flat negative side of the battery from making contact with the L E D driver circuit and destroying it due to reverse polarity...BUT...most 18650 battery positive end tips DO NOT fit the recess in the disc, so it prevents the flashlight from working AT ALL!! I have bought 12 of these lights...had to "modify" all of them. I carry two on me at all times, I have several in my vehicles, and have given some as gifts. In 5 years, the ONLY problem I've ever had was the initial need to modify the lights. Other than that, they are blindingly bright, highly reliable, light weight, and hold a charge regardless of the temperature of the vehicle they are stored in for months at a time. Good luck, and let me know how you made out!

I purchased the same battery LB1 High Performance Battery and after charging it for about 20 minutes, the light goes out on my computer,so something is wrong.It is not working like the factory battery did when it was new. Not satisfied here with the battery.

That's what I do...I run off the lithium battery until if gets low, then flip the switch over to the lead acid battery. I did have to change out the terminal, because my bike came with the bladed terminals and the lithum battery fits in with the buttoned terminal, but it was a cheap and easy fix.

Maybe that particular battery doesn't work? I ordered one and put it in, and it works great! Maybe send it back and have another one shipped out.

Maybe I can help. Anything you order through Amazon or one of Amazon's affiliates will be selling the latest product, as they could not possibly have the old units still in stock. I have the 2012 808U version, which was the updated battery, and have had no problems with the battery. I went for a night ride a couple weeks ago, about a 90 minute ride with the beam on high, and I still had PLENTY of battery life left. I can also comment on the ruggedness of the unit, because I ate dirt 6 times on that night ride and everything still works. The light is BRIGHT and will turn night into day for you. Maybe I can help.

The TechLite Lumen flashlights use 3 standard AAA batteries. If the battery holder is broken the cost of a new flashlight is low and the holder is probably not worth repair.

I was wanting to buy 3 of these units, for daughter, S.O. and mom, but I know some of them you can't use on a drained battery (say you leave your lights on in a parking lot for hours) and that's more what I'm looking for. Nothing like coming out to a dark, deserted lot and your car won't start even when you have AAA you have to wait...all alone ::shiver:: I guess I'll also wait and see if more feedback might come in. At the worst I can always go to a "store" and buy it :(

Just quit working on a ride to Montana...not sure why. Bought my wife one and it doesn't work either. I have it connected to the port I use for my battery tender so I know that's not the problem....

I got two of these lights in summer 2013. I had to return them as they stopped working after a few hours. This light has a great design and I like everything about it except that it does not work. Maybe some do but it is apparent from the comments that problems are widespread. The answers about removing the batteries solves a different problem. I would buy this light again if Energizer comes out with a new version that works.

Not in the traditional way as in trying to change the battery on your flashlight. The charge should last you a week if you brush twice a day. If it's a rather old unit, perhaps it's time to get a new unit. If you just got it, then it's definitely defective.

I have owned mine since the beginning of November 2014, and by the middle of December 2014, the light burned out. It also won't hold a charge. Without being able to replace the bulb and/or the batteries, I wish I'd purchased a different model. If the light lasted and the charge held, this would be 100% Awesome!!! (BIG IF)

The image shown looks to be back lit, but the one I bought is Not.Besides, having a light in side only runs your Battery down Quicker!Suggestion!, buy a small LED flashlight and keep it in a easy too locatespot (your pocket or in your Tool Box.).Raven

Hi Eugene, have bought the same unit, no problem so far. The blue light glows whilst it is charging. I would suggest checking you do not have a faulty battery first, all the battery polarities are correct otherwise it sounds like a fault in the lamp controller. Good luck! Apart from being a little heavy and not particularly pretty this is a great bike lamp, actually lights up the road.

there are two things you try out, one is to just install regular AA battery and if lights come on at night if this works this only mean that your rechargable battery need to be replace or need the solar cell is too dirty and need to be clean.

Remove the screws on the back and insert a new battery (or both). The replacement batteries don't seem to last quite as long as the originals, but the light will once again come on.
