How to prolong the lifetime of your battery?
. Use the original charger.
. Charge the battery after it automatically powers off , then full charge the battery.
. Avoid erroneous usage of battery, such as heavy pressure, short circuit, fall off and so on.
Advantages of lithium ion rechargeable battery
. Reduces the weight by half and volume by 20% to 50% compared to the same capacity nickel-cadmium and nickel-metal-hydride battery.
. Reduces the number of battery required since lithium ion battery can provide three times the voltage of Ni-Cd and Ni-MH battery, which contributes to miniaturization of electronic devices.
. Unlike nickel-cadmium battery, lithium ion battery have no "memory" effect, the effect which causes charging capacity to be reduced by repeatedly charging and discharging to insufficient levels, therefore, partial charging is possible.
. Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life. In addition, the self-discharge is less than half compared to nickel-cadmium, making lithium-ion well suited for modern fuel gauge applications. lithium-ion cells cause little harm when disposed.
. Most lithium-ion batteries for portable applications are cobalt-based. The system consists of a cobalt oxide positive electrode (cathode) and a graphite carbon in the negative electrode (anode). One of the main advantages of the cobalt-based battery is its high energy density. Long run-time makes this chemistry attractive for cell phones, laptops and cameras.
. There is only one way to charge lithium-based batteries. The so-called 'miracle chargers', which claim to restore and prolong batteries, do not exist for lithium chemistries. Neither does super-fast charging apply. Manufacturers of lithium-ion cells have very strict guidelines in charge procedures and the pack should be charged as per the manufacturers "typical" charge technique.
. A certain battery may be designed for small size and long runtime, but this pack has a limited cycle life. Another battery may be built for durability but is big and bulky. A third pack may have high energy density and long durability but this version is too expensive for the consumer. Battery manufacturers are aware of customer needs and offer packs that best suit the application.
