lithium battery is full of storage, can reduce the capacity loss
Correct understanding of: the loss of lithium batteries is completely different principle and lead-acid batteries
This idea can be described as wrong. Reduced life lithium batteries because it has the aging characteristics of the electrodes, even without the use of charge and discharge some of its capacity will be permanently lost. The reason is the battery electrode material from the factory after its failure has already begun the process. Under different temperatures and power failure at different speeds, the new factory after tests found that 40% of lithium battery to maintain power after one year at 0 can save 98% of capacity, fully charged the same temperature, then stored for one year left 94% of capacity, full power at 30-40 environment, save for one year, only 65% of capacity.

Therefore, long-term storage of lithium batteries is not recommended. Must be long-term storage, do not at full power and heat preservation case, it should be only about 40% of the electricity charge, and on the refrigerator compartment. 1, Li-ion battery discharge to the percentage of the most appropriate charge? For example, I spent 20%, the complete replenishment of the release in order to prevent relatively minor memory effect, or whether the fast charge Shang Hao. In fact, the key issue is that: each with a different ratio, such as 20% and 80%, whether the same degree of cell loss? If much worse, then the charge time. If you just spent on the loss of a back almost level, then it would run out of charge.
2, Li-ion battery charging frequent short short up against a large Mody (such as regular unplug the power, 10 minutes and then connect)?

Charge placed against the short short, or some, the damage size depends on your usage. What is bought, if considered too tired and also for its worth the the.

Is to pay attention to a few! Almost no memory effect Lithium! Discharge depth: comparison with batteries rated capacity, discharge rate COMPAQ Laptop Battery Dell Laptop Battery FUJITSU Laptop Battery . over charge (discharge) power: provided that exceed the battery charge (discharge) power state, if it continues to charge (discharge) power may result in battery leaks or deterioration. energy density: refers to unit volume or unit mass of energy released, usually with the volume energy density (wh / l) and quality of the energy density (wh / kg), said. Self-discharge: after fully charged battery, no contact with the external circuit, and placed under room temperature, its electrical capacity is natural attenuation. In the storage process, the battery charge storage capacity will be gradually decreased, reducing the capacity and the ratio of rated capacity, called self-discharge rate. Typically, the environmental temperature on the impact of large, high temperatures will accelerate battery self-discharge. Battery capacity fade (self-discharge rate) of the expressions are:% / month. Ni-Cd, Ni-MH battery self-discharge rate of 20-25% / month, lithium batteries self-discharge rate of 2-5% / month. http://www.articlesbase.com/hardware-articles/lithium-battery-is-full-of-storage-can-reduce-the-capacity-loss-2764935.html
