What's wrong with the LED rechargeable flashlight that has been lit all night long?
The flashlight battery doesn't work. It doesn't work. No general protection flashlight battery plate, is not overcharge too put, overcharge the battery over discharge and even explosive expansion, will cause the battery charging is completely destroyed, simply do not come back for a long time. I used my own flashlight, which was written on the instructions.
According to your question, the problem is that the battery is broken
Maintenance free batteries are dry. Maintenance free lead-acid battery is a residue.
