Dive Rite LED LUX battery problem

[sogig]

Hi fellows,

I am now cycling my new battery for the LED LUX canister light...

I found that the burn time is super short, also charged up fully the battery very fast (less than one hour)... is it normal?

Does anyone know what is the normal time to fully charge the battery?

Today, I charged and discharged the battery more than 5-6 times already... now the fully charge time is about 15-20 mins then light will go dark less than 20 mins.... :-(

Is it possible the battery already damage? Anyone knows how to "save" it, I only used it once :-(

Many thanks!!!
