Lithium Polymer Battery Charging Best Practices

To understand why it s important to appreciate how a battery charges.

Lithium polymer battery charging best practices. A li phosphate in a regular charger would cause overcharge. Leaving your phone or laptop plugged in all. The original charger will be of no use. Basically the charger will keep the current or charge rate constant until the battery reaches its peak voltage 4 2v per cell in a battery pack.

Partial charging is just fine for lithium ion batteries and can actually have some positive benefits for cell longevity. On the other hand nimh and nicd batteries charge best using a pulse charging method. Lithium ion suffers from stress when exposed to heat so does keeping a cell at a high charge voltage. Then it will maintain that voltage while reducing the current.

There are many ways to keep and prolong the life of lithium ion batteries. You can t completely trust your memories. We all know that extreme weather condition affects battery life and this includes the lithium ion battery. A battery dwelling above 30 c 86 f is considered elevated temperature and for most li ion a voltage above 4 10v cell is deemed as high voltage exposing the battery to high temperature and dwelling in a full state of charge for an extended time can be more stressful than cycling.

When purchasing a new dive light and powering it up without charging it first the battery will most likely be somewhere between 40 60 charged the lit battery indicator on the light will show the level of charge. Give those batteries long healthy lives. How to store a lithium ion battery. Trickle charge what your battery gets when it s connected and full is way less detrimental to the battery s health than a larger discharge would be.

Provision must be made to identify the systems and provide the correct voltage charging. What are the best charging practices for a lithium ion battery. How to charge your devices the right way. One of the best practices known to extend its battery life is to store it on room temperature.

If a lithium ion battery is discharged below 2 5 volts per cell a safety circuit built into the battery opens and the battery appears to be dead. Plug it in and charge it when you can and then rinse and repeat.
