Li Ion Polymer Battery First Charge

Find out how to prolong battery life by using correct charge methods.

Li ion polymer battery first charge.

In the first stage of charging a li ion battery or cell the charge current is controlled. The first is that you do not have to be obsessive. This affects each and every one. For new lithium batteries first charge time maybe longer.

High conductivity semisolid polymers form this electrolyte these batteries provide higher specific energy than other lithium battery types and are. 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. The first time charging and wait until full discharge before recharge and don t use when charging are not applicable to these modern batteries. Charging safely is a more difficult.

I made a post about this with my recent acer laptop over here. 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. A li ion battery reaches full charge when the current drops to a set level. When you leave your battery charged at 100 most of the time every year your max.

First charge time of lithium battery is often misled to activating theory. If you are using a trickle charge most chargers uses topping when the level of current drops. From the first to the last one you make before selling your smartphone or leaving it in a drawer. Charging and discharging batteries is a chemical reaction but li ion is claimed to be the exception.

For a 2 000 mah battery the charge rate would be 2 000 ma for a charge rate of c. Capacity will decrease with 20 25. 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. This is bad for the battery when you have this most of the time.

Read battery li ion science blog. Charging lithium ion batteries can be split into two main stages. Battery manufacturers usually recommend charging it at 08 c or even less to extend the life of the battery. 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.

How to first charge lithium ion battery. Typically this will be between 0 5 and 1 0 c. In terms of consumer electronics charge time of lithium batteries usually is 2 4 hours. Since lithium ion batteries don t contain cadmium they are also more.
