The battery must be kept charged at 40%. This threshold was defined as a precaution. The higher the threshold is lower and you risk depleting the battery completely and permanently damage. By cons, a fully charged battery is stored for an extended period is extremely bad, because the laptop battery will lose its ability faster. The reason is that the internal voltage is higher when the battery is full, increasing stress and wear. 40% is prepared by experts as the best compromise.
Attention, it is better to reach 40% loading and not drain the battery. Indeed, the operating system measures the level of support based on the current activity of the computer. For example, if the system is fully charged, it will calculate the remaining battery and determine the apple appropriate charge rate, but this APPLE PowerBook G4 12 Series Battery can quickly change if the operating frequency of the processor or the clarity of the screen down under road. Even if today the system is very accurate, it is best to be sure to have a reliable measure, to reach 40% by charging the battery.
Heat directly impacts the batteries. It is therefore crucial to keep the battery cool and dry. The best place is also the refrigerator. Indeed, it is estimated that a lithium-ion battery, charged at 40% and stored at 0 ° C maintained 98% of its capacity over a year. At 25 ° C (casio room temperature in principle), it increases to 96% capacity at 40 ° C it increased to 85% and 60 ° C, reaches 75%. As we have seen, charger on average, CASIO NP-20 charger a battery loses about 10% charge per month. Comparatively, a full battery and stored for one year at a temperature of 0 ° C will not maintain that 94% of its capacity. At 25 ° C, about 80% against 65% at 40 ° C.
For your information, the electrolyte present in the batteries from freezing -40 ° C (depending LM Cristo B and T. Atwater in the book Characteristics and Behavior of 1M LiPF 6 1EC: Electrolyte at Low Temperatures 1DMC. Fort Monmouth, NJ: U.S. Army Research). Concretely, this value is discussed, some speaking of -75 ° C to -30 ° C. Other We chose one that seems the safest. However, we found www.supply-batteries.co.uk CASIO NP-40 charger no source that does not recommend placing the battery in the fridge and come as close as possible to 0 ° C, optimum temperature of storage .
It is also important to clean the metal contacts on the battery with alcohol and dry thoroughly before replacing it in his computer. This operation, carried out every other month, ensures better conductivity.
The traces of time
A finding will perhaps be shocked, but whatever the temperature at which the battery is stored or its charge Olympus level, a rechargeable Li-ion battery loses capacity over time. In fact, a battery starts to age from its manufacture. The average battery lasts well preserved olympus li-42b charger and maintained in principle two to three years from date of manufacture. This is the result of 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 referolympus li-50c charger to the battery if it was kept on the shop shelf for 6 months. They are six months lost to you.
Finally, once your battery has passed away, what to do? The environmental risks are low, so that these batteries are designed to be unaware of leakage and are safer than cadmium for example. Nevertheless, it is clear that incineration will release toxic gases. If you know nikon d40 charger of a recycling program, then of course, build on them by disposing of your batteries in appropriate containers. You can also play the rule of "one for one" established during the transcription of European directives on recycling of electronics in French law by the implementing decree 2005-829. This decree provides, inter alia, that a dealer (offline or online) must pick up your old equipment if you bought a similar product at home (a screen for a screen, a PC to PC) and you so demands. Be aware that removal is supposed to be free.
A battery falls under the nikon coolpix s220 charger category of waste electrical and electronic equipment (WEEE). So if you buy a laptop or just a battery, you should be entitled to seek recovery of the battery or the computer by the dealer. After all, the environmental levy is there to come and support the cost of this recycling effort.
