Lithium Polymer Battery Charge Cycles

Unlike nicad batteries lithium ion batteries do not have a charge memory.

Lithium polymer battery charge cycles.

This process is not some kind of magic but you can charge your li ion batteries without using your charger. 9 x 5 5 x 4 inches. Yes there are specific ways you can charge your li ion batteries without the charger. Assume that the capacity provided by a full discharge is q.

Lithium ion suffers from stress when exposed to heat so does keeping a cell at a high charge voltage. Full charge discharge cycles should be avoided if possible. 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. Their overall life span is comparatively much shorter about 500 800 charge cycles especially when used in high demand applications ie high discharge lipo battery 250 500 charge cycles.

The life of a lithium battery is generally 300 to 500 charging cycles. First continuous trickle charging of a full battery can cause plating of the metallic lithium which reduces stability in the long term and can lead to system wide malfunctions and reboots. Chargers for these non cobalt blended li ions are not compatible with regular 3 60 volt li ion. A li phosphate in a regular charger would cause overcharge.

The correct saying is that lithium ion battery cycle life is related to complete charge cycle time without direct relationship with charge time. A 3 60 volt lithium battery in a charger designed for li phosphate would not receive sufficient charge. In fact it s better for the battery to use partial discharge cycles. 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.

Provision must be made to identify the systems and provide the correct voltage charging. Misunderstanding on lithium battery cycle life is that battery needs replacing after 300 to 500 cycle times. Here is another way to think of the cycle lives of lithium ion polymer batteries. That means deep discharge cycles are not required.

Lithium ion and lithium polymer batteries should be kept at charge levels between 30 and 70 at all times. A charge cycle is lithium battery fully charged then completely discharged then recharge that is not equal to charge one time. Lithium polymer battery popularly known as lipo battery works on the lithium ion technology instead of the normally used liquid electrolyte.
