Battery memory effect, lead-acid battery and lithium battery have any memory effect

Life, found that many people's cell phone will always be in a state of preparation without electricity, must be used to turn it off just to charge; Always someone like obsessive compulsive disorder, be sure to charge to one hundred percent. Because a lot of people think the battery has memory effect, must do this is to love the performance of the battery. However, today's battery in the majority with lithium battery and lead acid batteries. So what is the battery memory effect mean? Lead acid battery and lithium battery has a memory effect? Battery memory effect battery memory effect battery memory effect refers to the reversible battery failure, namely the performance of the battery can be reactivated after failure. Cells undergo specific work cycle for a long time, tend to keep this particular automatically. Popular, is the battery to remember the last node, charge and discharge for later unable to break through the nodes lead to battery capacity is reduced. Due to negative extremely sintering type in the traditional process, cadmium coarser grains, if nickel cadmium battery recharge before they are completely discharge, cadmium grain easily gathered into pieces and make a battery discharge form secondary discharge platform. Battery will store the discharge platform and it as the end of the discharge in the next cycle, although the capacity of the battery itself can be make the battery discharge to the lower platform. In the process of after the discharge of battery will only remember that low capacity. The same in every use, any incomplete discharge will deepen this effect, make the capacity of the battery is lower. Lead-acid battery electrodes is mainly composed of lead and its oxide, the electrolyte is a battery of the sulfuric acid solution. Discharge condition, the positive main ingredients for lead dioxide, negative main composition as the lead; Charging status, the main components are all lead sulfate is negative. With the upgrade of battery manufacturing technology, lead-acid battery development for lead-acid maintenance-free battery and colloid and maintenance-free batteries, lead-acid battery to add electrolyte or use distilled water. Mainly using the positive produce oxygen can be in negative oxygen absorption to circulation, can prevent the water cut. When the discharge of the concentration of the sulfuric acid solution will decrease, while the density of solution 1. When 18 g/ml, should stop using the recharged. With the upgrade of battery manufacturing technology, lead-acid battery development for lead-acid maintenance-free battery and colloid and maintenance-free batteries, lead-acid battery to add electrolyte or use distilled water. Mainly using the positive produce oxygen can be in negative oxygen absorption to circulation, can prevent the water cut. Lead acid battery and lithium battery have any memory effect if the battery is nickel cadmium battery, long-term is not complete charge and discharge, easy to leave a mark inside the battery, the phenomenon of lower battery capacity. Batteries like memory user daily charge and discharge rate and the mode, time is hard to change this pattern, can no longer do greatly charging or discharging. Lithium battery no such effect. Lead-acid battery has no memory effect, while lead-acid battery don't then there will be capacity attenuation phenomena, but that is sulfide, not memory effect. And memory effect and sulfide ways are not the same. Memory effect of the response is periodic, depth of discharge to empty the battery and sulfide is as far as possible to cope with the charge every time. Due to the characteristics of lithium battery itself, determines its almost no memory effect. So new lithium-ion batteries in the user's phone in the process of activation, is don't need special method and the device. Not only in theory, from my own practice, from the start with a standard method of charging this & other; Natural active & throughout; Is the best way. Lithium batteries in accordance with the best charging standard time and standard methods, especially don't charging for more than 12 hours long. Usually, the introduction of charging method, on the phone's manual standard charging method is suitable for the mobile phone. Lead-acid battery maintenance way 1. After use to charge in time, can't long time no electricity condition place; 2. Pay attention to check the tire pressure, can be appropriately lower in summer, you can make some other season, tire pressure is high to compare save electricity; 3. If you don't use electric electric bicycle for a long time, to pay attention to the battery and then placed a monthly check power; 4. Often clear the dust and dirt on the battery compartment, pay attention to keep the battery dry, clean, in case the battery to discharge, 5. The battery don't close to the high temperature heat source. High temperature season, it is strictly prohibited in the sunlight insolate directly, charging must pay attention to the good ventilation; 6. Try to avoid slamming on the brakes, brakes frequently will consume large amounts of electricity, also can damage the battery. Read the article you see, in addition to the nimh battery memory effect, most of the lead acid battery and lithium battery has no memory effect, along with the best filling, lead-acid battery should try to keep the electricity to stand, and both normal use discharge self-discharge placement should be in charge when battery capacity more than 30% to the full, avoid is often large current deep discharge and kui state, lithium battery best not full electric or deficient electric placed, with power remained at 60% capacity advisable, dry cool place to store.
