As storage batteries?
The battery must be kept charged at 40%. This threshold is defined as a precaution. The higher the threshold is lower and the risk depleting the battery completely and permanently damage. In contrast, a fully charged battery is stored for a long period is very bad, because the laptop battery will lose its ability faster. The reason is that internal stress is greater when the battery is full, increasing stress and burnout. 40% is prepared by experts as the best compromise.
Attention is better to get a 40% charge and not drain the battery. Of Indeed, the operating system measures the level of support based on current computer activity. For example, if the system is fully charged, it will calculate the remaining battery and determine the appropriate charge rate of apple, but Apple PowerBook G4 12-series batteries can quickly change if the operating frequency of the processor or clarity of the screen down the road. Although at present the system is very accurate, it is best to be sure of a reliable measure, to reach 40% of the burden of battery.
Heat problem
The heat directly affects the battery. It is therefore crucial to keep the battery fresh and dry. The best place is the refrigerator. In fact, it is estimated that a lithium-ion battery, charged to 40% and stored at 0 ° C maintained 98% of capacity over a year. At 25 ° C (room temperature casio in principle), which increases to 96% capacity at 40 ° C increased to 85% and 60 ° C, reaches 75%. As we have seen, the charger on average, NP-20 charger a battery loses about 10% charge per month. By comparison, a full battery and stored for one year at a temperature of 0 ° C will not keep that 94% of its capacity. In 25 ° C, about 80% against 65% at 40 ° C.
For your information, this electrolyte in the batteries to freeze -40 ° C (depending LM Christ B and T. Atwater in the book of the characteristics and behavior of 1M LiPF 6 1EC: Electrolyte 1DMC low temperatures. Fort Monmouth, NJ: U.S. Army Research). Specifically, this value is some talk of -75 ° C to -30 ° C. Other We have chosen one that seems the safest. However, we found www.supply-batteries.co.uk CASIO NP-40 charger source not recommend placing the battery in the refrigerator and come as close as possible to 0 ° C, optimal storage temperature.
It is also important to clean the metal contacts on the battery with alcohol and dry completely before replacing it on your computer. This operation, carried out every two months, says better conductivity.
The traces of time
One result may be surprised, but whatever the temperature at which the battery stored or charge level of Olympus, a rechargeable Li-ion batteries lose capacity over time. In fact, the battery begins at the age of manufacture. Battery has an average duration of good state of repair charger Olympus LI-42B and maintains, in principle, two or three years from the date of manufacture. This is the result the oxidation of cells, normal phenomenon when the battery is in use or aging. It is therefore important to know the date of manufacture or before the time of purchase. If you ordered online, please title = "OLYMPUS LI-50C Charger"> olympus li-50c battery charger if it remained on the shelf Shop for 6 months. Are you lost for six months.
Finally, once the battery is dead, what do you do? The environmental risks are low, so these batteries are designed to be unaware of the leak and are safer than cadmium, for example. However, it is clear that incineration may produce toxic gases. If you know Nikon D40 charger in a recycling program, of course, build on them by disposing of batteries in appropriate containers. Also can play the rule of "one on one" established during the transcription of the European directives on recycling electronics in French law the implementation of Decree 2005-829. This decree provides, inter alia, a dispenser (or offline) to pick up his former team, if you bought a product similar at home (a screen of a display, PC to PC) and as required. Note that removal is supposed to be free.
A battery goes category Nikon Coolpix S220 Charger waste electrical and electronic equipment (WEEE). So if you buy a laptop or a battery, you must have the right to request the recovery of the battery or the computer by the dealer. After all, the environmental tax is not coming to cover the cost of this recycling effort.
