Li Ion Polymer Battery First Charge

In the first stage of charging a li ion battery or cell the charge current is controlled.

Li ion polymer battery first charge.

The basic algorithm is to charge at constant current 0 2 c to 0 7 c depending on manufacturer until the battery reaches 4 2 vpc volts per cell and hold the voltage at 4 2 volts until the charge current has dropped to 10 of the initial charge rate. Battery manufacturers usually recommend charging it at 08 c or even less to extend the life of the battery. First charge time of lithium battery is often misled to activating theory.

The modern batteries that equip all smartphones are designed to withstand a broad cycle of charges. Charging lithium ion batteries can be split into two main stages. How to first charge lithium ion battery. Lithium ion batteries are more reliable than older technologies such as nickel cadmium and don t suffer from a problem known as the memory effect where nicad batteries appear to become harder to charge unless they re discharged fully first.

In terms of consumer electronics charge time of lithium batteries usually is 2 4 hours. For new lithium batteries first charge time maybe longer. Capacity will decrease with 20 25. The first time charging and wait until full discharge before recharge and don t use when charging are not applicable to these modern batteries.

For a 2 000 mah battery the charge rate would be 2 000 ma for a charge rate of c. Find out how to prolong battery life by using correct charge methods. I made a post about this with my recent acer laptop over here. Typically this will be between 0 5 and 1 0 c.

The complete charging time will take about 2 to 3 hours. When you leave your battery charged at 100 most of the time every year your max. The first is that you do not have to be obsessive. High conductivity semisolid polymers form this electrolyte these batteries provide higher specific energy than other lithium battery types and are.

Li ion and li polymer batteries if charged often after about 1 month would reach to their maximum performance and you are recommended to charge them every time you find an outlet. Charging safely is a more difficult. If you are using a trickle charge most chargers uses topping when the level of current drops. This affects each and every one.

From the first to the last one you make before selling your smartphone or leaving it in a drawer. The lithium ion battery is easy to charge. This is bad for the battery when you have this most of the time. A lithium polymer battery or more correctly lithium ion polymer battery abbreviated as lipo lip li poly lithium poly and others is a rechargeable battery of lithium ion technology using a polymer electrolyte instead of a liquid electrolyte.
