LI Battery
Charging n Care Tips

It is important to learn battery care information for Lithium-ion batteries to enhance the performance and extend the useful life of the battery. Because they are the newest technology batteries, they offer several advantages over NiMH and NiCd batteries.   Lithium-ion batteries are preferred for their lighter weight and higher performance.  Lithium-ion batteries are typically 20-35% lighter and will provide 10-20% better performance than a NiMH battery of equivalent mAh rating.  Lithium-ion batteries are also unique in that they are not susceptible to the "memory effect".

A new Lithium-ion battery will benefit from an initial "conditioning" of the battery.  For the first 3 charge cycles, fully charge the battery overnight and allow it to fully discharge before recharging.   Once conditioned, Lithium-ion batteries will perform best when charged at a rate somewhere between a conventional slow charge and a rapid charge.  When rapid charging, Lithium-ion batteries require a charger designed to charge Lithium batteries.  To achieve a true full charge when rapid charging, the battery needs to be slow charged the last 10-15% of its charge cycle.  Most "intelligent" desktop and Lithium-battery rapid chargers provide this capability.  A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours).

Li-Ion Batteries -
The newest category of commercially available rechargeable batteries are the Li-Ion batteries. These batteries have all the advantages of Ni-Cad and NiMH batteries plus they have a longer useful life than either of these two types of rechargeable batteries. The main disadvantage to Li-Ion batteries is that they lose about 10% of their useable capacity each year due to chemical breakdown within the cells. There is nothing that can be done to prevent this condition..

Li-Ion batteries have a typical useful life of between 300-500 discharge cycles or about 4-5 years. You can maximize the useful life of your Li-Ion batteries by keeping them on the charger during use (e.g. laptop computer) or keeping them on the charger when not in use. Because Li-Ion batteries are "smart" batteries they cannot be overcharged.

Because Li-Ion battery life is dependent on the number of discharge cycles, anything you can do to minimize the number of discharge cycles will, in effect, increase the battery's useful life.

Here's a Li-Ion battery maintenance tip; Li-Ion batteries should be conditioned about once a month. Most Li-Ion batteries have a fuel gauge on the battery (i.e. the LEDs on one side of the battery with a test button) and the electronic device (usually a laptop computer) also has monitoring software to manage the battery power. The accuracy of a Li-Ion battery's self-monitoring circuitry degrades after about a month of use. If you notice that your battery's fuel gauge or your device's operating time estimate is way off, then you probably need to condition your battery.

To calibrate (or condition) your Li-Ion battery, fully charge your batteries (let them charge overnight even if they appear to have a full charge) then operate your device until it shuts down. Recharge your batteries and you should notice an improvement in the accuracy of the operating time prediction.
