Analysis of the correct use of the technique of lithium-ion batteries

Source: 2020 - 03 - 25 to pronounce hits: proper use of lithium battery tips? Recently, consulting about battery, I see a lot of friends have a central problem, is roughly: battery life is short, not durable; Battery operating safety; Because of the current basic all electronic products, only need wireless charging, more than half are using lithium battery, so how to better use of electronic products with battery? Let us use this product to outline some skills: 1. When charging don't play with mobile phone charge, try not to use mobile phones and other products are all the same, when charging the use of mobile phones damage is very large. 1: increase radiation; 2: damage to the battery, shorten service life; 3: battery explosion probability of the basic charge and discharge time, avoid a personal injury; Flushed the edge it is dangerous to play 2: after a full charge timely pull the plug, remember to unplug the power and assume that continue to charge a full charge, the battery internal resistance will grow big, damping capacity, affect battery life; Unplug the power supply in time, after full charge still responsible for mobile phone, to avoid falling asleep, in the past for a long time, the cycle of the battery life will be in free fall, do you know the number class lithium battery after-sales service need only one year. Before the orders of the universal, should not see 3:00 after charging don't carry a heavy suitcase or standby power supply when the purse under the condition of the normal lithium battery charging, mobile phone may own heating, heat part is battery, part PCBA heat dissipation. Assume that thick skin case could be standby charge paper clips, heat dissipation for batteries. When the temperature reaches a certain temperature, the battery will fire or explosion. We usually put the battery temperature control within the 60 degrees, the high temperature battery can support 80 degrees Fahrenheit, this is the use of high temperature detection, we can in our daily use is very clever. Heat 4 his suitcase. Charger is the choice of mobile phone, bluetooth headset, smart wear watches, and tablet computer products, such as charging time, try to use the factory original charger, the charger to use lunch and optional, assuming that the voltage current mismatch, so big damage part of the battery, battery, and a threat to the battery stop protection, but the battery life will still have a big impact; A simple example: suppose mobile phone battery capacity is 4000 mah, so let us use 5 v - 1a ~ 1. 2 a charger to stop, just 4 hours full; Hypothesis 5 v - 300 ma and 500 ma charger, at least 8 hours full of talent, assuming that there is no way to choose to remember the charging current is not easy to easy to small to large; ( Warm prompt: do not recommend the use of the output voltage is greater than 5 v charger, 4000 mah battery does not recommend the use of the output voltage is greater than 2 a charger, unless there are instructions support quick charge. ) Output 5 v - 300 ~ 500 ma charger 5. Need timely charging use timely stop charging batteries, lithium battery when the power of a product is less than 10%, generally appear red, the demand for the product this time immediately stop charging, conditions allow, don't wait for the battery charging is complete shutdown, is a great damage to the battery. Charges will be collected at the bottom of the red above is the tips to share with you today and the matters needing attention, hope you pay attention to safety when using electronic products
