The problem with LED charging lamps?
1, if the discharge to the LED desk lamp out recharging, the battery is already in a state of over discharge, discharge will seriously affect the battery life; 2, usually, when the discharge to about 80% of the nominal voltage battery, should be used to recharge the battery. Such as: the nominal 3.7 V lithium electricity, discharge to about 3 V, must charge nominal 6 V lead-acid battery, discharge to about 4.8 V must charge; 3, LED desk lamp is very save electricity, if the battery capacity is larger, continuous discharge ability is stronger, in the process of the whole light, LED lamp brightness change also be aware of not easily, just by visual inspection, indeed not easy to decide when discharge end; The easiest way to use multimeter test battery voltage to judge whether the charge. Hope the above reply to help you.
Bright LED the longer elucidation and rechargeable lamps are of good quality and good brand of things you can rest assured use!
You look at the instructions, if 10 hours are used up, then the general new will be more than 10 hours. The big brands generally describe relatively conservative performance objective.
Now technical innovation, new types of LED lights are super save electricity. Filling desk lamp I felt at least on a 12 hours in order to be qualified, otherwise how enough
