Lithium batteries can overheat or overcharge explosion, cell phone lithium battery explosion news h


Lithium batteries can overheat or overcharge explosion, cell phone lithium battery explosion news have also been reported. While charging the phone with an electronic chip to control the charging voltage and current, will stop charging after full power, relatively density of air table safe. Of course not cheap rechargeable density of air table fan wafers, using only ordinary USB phone charger direct charge, it is very dangerous. The lithium battery density of air table is only 3.7V, power is 2,200mAh, you should use the charging voltage of about 4V, and when the charge is also necessary to limit the current. The general USB charger voltage of 5V, the current range, density of air table directly to the lithium battery charging from 0.5 to 2A, in the absence of current limiting protection less than 1 hour can be filled. If you continue to charge, have the opportunity to overheat explosive, very dangerous.
