LED lamp rushed into electricity, no battery is bad, but is not into electricity, charging indicator light (not bad) didn't also bright, is how to return a responsibility?
Charging circuit disconnection or the charger itself has a problem
The current charging lamp pass much, just buy a new can also, the longer the storage function will reduce in the end just charge it into electricity, problems in the internal rechargeable battery, it is no longer able to store energy so I won't charge electricity. Tell you I have a you so the desk lamp of the same, not thoroughly with the eight months, I finally changed only USES a small battery now. I can because I love electronics repair maintenance.
Light is not bright, can be sure is there is something wrong with the wire or internal charging circuit has a problem. Judge fault: 1, if the line is broken, looking for businesses of the same wire, in a first try (don't have to buy wire to test), indicator is not; 2, the light is bad, but little chance (if this is the case, the battery doesn't charge into the electricity, the battery has high pressure resistance state sulfide, battery need to be repaired). 3, internal charging line fault: most likely internal CBB capacitor to boil road, need to change. For this kind of lamp, the most easily broken electronic components in the charging circuit is the CBB capacitance. Can go to the repair shop repair. Only more than 1, 3 kinds of possibility is high, the highest 3, was ruled out small battery (internal small battery) problem, because the light is not bright, batteries to electric light advocate the lamp, that the battery is resistance, capacitance resistance step-down charging circuit to charge of no-load voltage can reach more than 300 v, is impossible, and no current flows through the indicator as long as is good will on, even if the battery fully charge it into electricity, indicator light will be bright. I have a problem is battery repair instrument design engineers, can ask me, I design the battery repair instrument can repair indicator but any vulcanization of battery and charge it into electricity. There is a way to judge whether there is a current through the, is at the moment of plugged into the plug has a tiny 1 of "pa", or "chip", close to the ear, can hear, careful observation can even see tiny spark, then the CBB capacitance not bad, but the light is bad, and the battery has the possibility of sulfide. Downstairs and a brother named longsheng fushun said about the battery internal resistance and resistance capacity no-load voltage of charging circuit, considered a battery sulfide failure (charge it into electricity, indicator), but not necessarily.
