Question: What are the advantages of a lithium-ion battery?

Answer: Lithium-ion batteries are the latest technology for portable use. These batteries do not suffer from the memory effect. Compared with a Ni-Cd battery, these batteries will deliver twice the runtime on each charge. It is available only in a limited number of sizes and models. They have a life expectancy of 300-400 charge/discharge cycles. Generally, lithium batteries are designed to be recharged in the device rather than in an external charger.

Question: If a battery charger will charge NiMH and Ni-Cd, will it charge lithium-ion batteries also?

Answer: If it is not listed for lithium-ion batteries, then it should not to be used to charge them.

Question: What are the differences between a Lithium-ion Polymer battery and a Lithium-ion battery?

Answer: There are three main advantages to a lithium-ion polymer battery -- lighter weight, a wide range of possible shapes and greater performance at high and low temperatures. A lithium-ion polymer is lighter than a standard lithium-ion battery because it uses a plastic electrolyte instead of an electrolyte solution, as is used by lithium-ion batteries. This plastic electrolyte (called polyacrylonitrile) also allows manufacturers to make batteries in diverse shapes. Lithium-ion batteries are limited in shape by the electrolyte solution. Thirdly, polyacrylonitrile has a high-performance discharge capacity at both lower and higher temperatures, as shown in the table below: 0?C 96% -10?C 86% 90?C 100% Question:How should I charge my battery the first time? Answer:For the first 3 charge cycles, a new battery should be fully charged before being used and then allowed to fully discharge before recharging.  This will help ensure a true "full charge" of the battery during the first few cycles and will condition the battery for optimal performance.  Proper conditioning of a new NiMH battery is critical to achieving optimal performance.  While less critical for Lithium-ion batteries, proper conditioning will provide benefits to new Lithium-ion batteries.  Note that when a new battery is first charged, it is not unusual for the battery to show a full charge after only a short period of time.  If this occurs, keep the battery on the charger overnight to help ensure a true full charge.  Removing the battery momentarily from the charger and then replacing it may also help.  Question:How long does it take to fully charge a battery ? Answer:The time required to charge a battery depends on the battery type, the capacity of the battery, and the type of charger being used.  A higher mAh battery will take longer to charge than a lower mAh battery.  In general, it will take 3-4 hours to "rapid charge" a battery to the 80% level, and an additional 8 hours to 搒low or trickle?charge a battery to the 100% level.  A good approach is to charge your battery overnight for about 12 hours.   Question:Will overcharging my battery hurt it ? Answer:Yes, overcharging a battery causes it to overheat and can result in damage to the battery, causing degraded performance and eventual failure.  As a general rule, do not charge a battery for more than 24 hours. Question:How long will a battery last ? Answer:In general, the life of a regularly used battery is between 300 and 500 charge/discharge cycles.  Depending on the battery, this translates into a 1-to-2 year timeframe.  As a battery nears the end of it's productive life (typically considered 50% of its original capacity), the talk and stand-by times of the battery will be noticeably shorter.  It is interesting to note that a Lithium-ion battery will, over it's useful lifetime, maintain more of a full capacity charge and then "die" rather suddenly; a NiMH battery will demonstrate a more gradual decline in performance as it nears the end of it's productive life. Question:Why can't I find a Lithium-ion battery that matches the battery voltage specified for my phone ? Answer:Lithium-ion batteries typically operate at slightly higher voltage levels than their NiMH counterparts (for example, a 7.2V Lithium-ion is the typical equivalent for a 6.0V NiMH).   The higher voltage Lithium-ion batteries are completely compatible and will not adversely effect the phone.
