In recent years, with the progress of lithium technology and the reduction of production costs, lithium batteries as the main power source of lithium electric scooters also flew into the common people, lithium compared to the traditional lead-acid batteries, has a light quality, long cycle life, high energy density, fast charging speed and other advantages. Most lithium batteries are designed to last around 1000 cycles (ordinary ternary lithium materials), which is 3-4 years. But this does not mean that after 3-4 years of use, the life of the lithium battery is terminated, as long as the usual attention to these points, 36V 12Ah skateboard battery life can be doubled! We take the current mainstream ternary lithium battery as an example, the mainstream manufacturers produce lithium batteries with 18650 cells, the main characteristics are high energy density, high cycle life, moderate manufacturing costs, but the use of the environment and charging requirements are relatively high.
36V 12Ah skateboard battery is afraid of cold and heat, do not use in extreme environments
In summer many people like to put the lithium battery electric scooter in the sun, or in winter is also parked in the yard or on the road, which is very unfavourable for the service life of lithium batteries, lithium ion in the electrolyte and electrode sheet migration rate is closely related to the temperature, theoretically the temperature between -20 ℃ -55 ℃ can be used normally, in daily life, lithium battery temperature between 5 ℃ -35 ℃ In daily life, the lithium battery can be used at a temperature between 5°C and 35°C. The lithium battery is not harmed by the temperature between 5°C and 35°C. Users in the north should store the lithium battery at home in winter, not outdoors, and avoid exposure to the sun in summer.
36V 12Ah skateboard battery should not be charged and discharged in depth often
Many people think that the electric scooter manual lithium battery hundreds of times the number of cycle charging is as long as plug once even if used once, in fact, this is a misunderstanding, the manual actually refers to the number of completely re-discharge, lithium batteries are different from nickel-cadmium batteries, lithium batteries do not have any memory effect, can be recharged at any time, anywhere, the battery has spare power to charge not only will not shorten the service life, but also to the battery The correct approach for lithium batteries is to charge them slowly rather than deeply.
The 36V 12Ah skateboard battery should be charged with a suitable charger to avoid high currents.
The chemical activity of Li-ion batteries is much more active than lead-acid batteries, and the requirements for chargers are much higher. Once you use a miscellaneous charger or an unsuitable fast charger, it will not only affect the service life of the Li-ion battery, but also cause an explosion due to overheating and short circuiting of the diaphragm. In addition, 18650 battery is 3c discharge, your electric scooter is 350w, with the battery is lower than your electric scooter discharge current, this will lead to lithium battery temperature is too high, the current is too large and shortened life, there will be bulging scrap, if your electric scooter car power is very large, very fast, it is recommended to choose 10c current 18650 battery, so choose the right It is obviously very important to choose the right battery cell!
Don’t “overcharge”, don’t “activate” the lithium battery
Many users buy a 36V 12Ah skateboard battery and then charge it for 10-12 hours for the first three times as they do with lead-acid batteries, thinking that the lithium battery needs to be activated, which actually affects the life of the lithium battery. The correct approach is to unplug the battery after it has been fully charged. 36V 12Ah skateboard battery should not be charged overnight as it is prone to fire.
36V 12Ah skateboard battery does not need to be stored fully charged
36V 12Ah skateboard batteries (18650 cells) are usually purchased with 2-3 cells, rarely with a full charge, and a long storage time with a full charge will reduce the capacity of the lithium battery. Another thing to note is to choose a better quality protection plate. Pay attention to these points, your electric scooter car lithium battery with a five or six years is no problem.
