Hello friends ! I'm Ostin. I like to explain about, how to esprit dead desk lamp ? It is very easy, simple and saves bucks.
Usually led desk lamb dies soon, Mostly these problems are not due to circuit failures but batteries. These batteries are mostly lead acid type.
To be frank 99 % of led lamps are made in china. It takes very long to time to reach customers in various parts of the world, By then the lead acid in the battery gets dried up or they are not filling acid enough .
I'm facing this problem in almost all the electronics, which is included with this type of batteries. This is why china electronics dies often. Let me explain you, how to fix this?

Usually these types of battery are advertised as maintenance free and non reusable,But it is not.
Step 5: Inject Distilled Water
Use syringe and inject distilled water in to the battery. It consumes very low quantity of distilled water, around 10 to 20 drop. Dont worry even if it consumes less.
Fill it till neck. Do not pour out any liquid from battery .
Step 6: Solder the Terminals
Enclose the battery and solder the terminal.
Replace the bottom cover and screw It up.
