What do you need to pay attention to when charge a lithium-ion battery for the first time?

The battery of the phone mostly is lithium-ion battery. Lithium-ion battery is small and safe. It is very applicable for mobile phone. When you want to buy a new phone or new cell phone battery, many people have heard to charge for enough electricity, so that mobile phones have lower power consumption in the future, and mobile phone can work for a long time. How long is lithium-ion battery charge for the first time?

Lithium battery charging time for the first time

Battery capacity is mAh, how many ma discharge speed, discharge can discharge the meaning of an hour.1500 mAh battery discharge at 1500 milliampere discharge speed can be used for an hour, with 500 milliampere (500 ma) discharge rate, need to use 3 hours.

Lithium battery charging error for the first time

Myth: charging for the first time, need to activate the cell phone battery?

First of all, this sentence itself is a problem, you buy a mobile phone, mobile power has not been activated, then why did you buy these have electricity? That is because has good activation and test before they go out. So this will not need to activate.

In fact this "must be filled in the first three time charge 12 hours" enough that it is obvious from the early nickel battery, such as nickel cadmium and nickel metal hydride) continue down.

Basic has shifted to modern industrial mobile phone use lithium batteries, and lithium batteries with nickel batteries have different properties. So as long as the same as normal fully charge and then draw it out.

Earlier nickel cadmium rechargeable battery and nickel metal hydride rechargeable batteries, these batteries will produce a phenomenon known as the "memory effect", in the condition of incomplete discharge of charging, the battery overcharge, will lead to long-term plates on hyperplasia of crystal, blocking the electrolyte and electrode plates contact, cause the battery voltage to drop, let users having the feeling that the battery soon ran out.

Erroneous zone 2: the battery after the need to refill? Cause excessive charging battery explosion?

Lithium ion batteries large energy density, high voltage (single lithium ion battery cell voltage 4.2 V, and ordinary nickel-based rechargeable battery is 1.2 V), and low voltage class compared to batteries, lithium ion battery electrodes with the REDOX reaction of very severe, so the use of lithium ion battery conditions must be tightly restricted, overcharge, excessive discharge and short circuit, high temperature can cause cell damage, even fire and explosion. However, actual use of lithium ion battery is to put a number of batteries along with a set of safety protection circuit and a variety of safety devices together into a piece of panels. These safe designs can ensure the excessive, excessive discharge and short circuit automatically cut off the battery charging circuit; The battery internal pressure is too high will trigger the exhaust pressure; Battery temperature too high will trigger the thermal protection device, block of lithium ion movement to stop the electrochemical reaction of the battery. Therefore, as long as you are not with the quality of the erratic counterfeit batteries, cell phone charge not unplug the power does not cause the battery explosion in a timely manner.

Myth 3: the battery can charge the battery by reducing the number of, can extend battery life?

Digital devices will identify charging can charge up to hundreds of times, actually this is under the environment of the deep discharge detection, that is, the battery will be used up and then charge it to full electricity, this cycle, continuous deep discharge for battery.

And our daily charge, in fact is a shallow discharge, battery hadn't run out also will continue to, this way of well than deep discharge for batteries, shallow discharge battery last longer than deep discharge use.

In addition, the battery for a long time need not, try to keep at around 70% of the battery, it is favorable to the maintenance of the battery and reduce the damage to the battery; Studies show that lithium ion deposit in full charge of the state for a long time, its apparent loss capacity. Similarly, the higher the temperature, the capacity loss of lithium ion battery more quickly, and this loss is not reversible, that is, the capacity of the battery will permanently smaller. Under the environment of zero, the remaining 40% of the lithium ion battery to store a year later, the capacity loss will be 2%;40 degrees in the environment, fully charged lithium-ion batteries to store a year later, the capacity loss up to 35%.

The lithium battery charging time for the first time may be determined according to the actual battery capacity. A lot of people charge lithium-ion battery for eight or nine hours for the first time. Actually, there is no need to charge for so long. It is not good for durability to charge cell phone lithium battery for a long time. At present, most of the mobile phone is smart phone. The screen is big, so power consumption is large. Even if how large capacity lithium-ion battery has, if cell phone is used for a long time, it still needs to charge every day. You can prepare for a charger if your phone has large power consumption.
