Can batteries last indefinitely?
No. Both rechargeable batteries and disposable batteries have a certain lifespan for their use, whether it is external damage or the battery itself will eventually become obsolete.
Death of disposable batteries
Disposable batteries are usually stored in the electrolyte, when used, the electrolyte reacts with the positive and negative materials to release power, however, this reaction cannot be easily reversed, and timely not to use him will also slowly respond until completely.
The death of rechargeable battery
Rechargeable batteries also rely on chemical reactions to achieve the storage and release of power, unlike disposable batteries, rechargeable batteries can be supplemented by the reaction of the charge to achieve the reaction of the reverse, but this reaction is not complete every charge and discharge will lose part of the electrolyte in the form of reactants in the positive and negative electrodes, the electrolyte gradually over a long period of time can not meet the charging and discharging requirements of the battery on the death of the natural.
The reasons for the death of the battery are those
(1) life expectancy, of course, this is the ideal way to damage the battery use have cycle times.
(2) over-discharge, a fully charged battery where, has not been used he will discharge a certain amount of power every month really to all the power discharge, in the over-discharge of the battery will lose the ability to charge and discharge, the general use of batteries will not be over-discharge phenomenon, the battery will always be a little bit of power is not enough to meet the equipment operation.
(3) overcharging, for the rationale for the battery when overcharging the battery will produce internal crystals, while excessive electricity will make the generation of a large amount of heat, with the internal expansion of the battery burst lithium and air contact will explode and catch fire, at this time, the life of the battery is also terminated.
(4) extreme weather, cold weather in winter, the degree of reaction in the battery to reduce the battery storage capacity decline, which will not damage the battery, in the summer hot weather under the sun, the battery will be huge damage, the loss of electrolyte in the high temperature environment will accelerate the loss of the battery, while the battery continues to work also makes the aggravation of the aging of the electricity, the most serious directly lead to the battery will be scrapped.
(5) electrolyte leakage, for lead-acid battery electrolyte is flowing acid, followed by the use of distilled water should be increased frequently, lead-acid battery damage electrolyte leakage will directly lead to battery damage.
(6) electrical short circuit, the positive and negative battery cannot be contact, lead-acid batteries for long periods of time when the battery active substances gradually accumulated in the battery, resulting in positive and negative plates in contact with each other will directly lead to the death of the battery scrapped.
(7) acid stratification, acid stratification often occurs in the lead-acid batteries are not fully charged, not fully charged lead-acid batteries to supply a variety of equipment, charging time required to extend the electrolyte in the acid began in the lower part, resulting in sulfate in the lower part of the aggregation, the battery’s charging and discharging capacity is weakened, the acid in the upper half of the electrolyte due to the impact of a strong will strengthen the corrosion of the battery soon after the battery will be Soon the battery will be directly scrapped.
Conclusion
In fact, most of the accelerated death of the battery is the use of human factors, no matter how the quality of the battery should be in accordance with the standard of battery use, while appropriate battery maintenance can also increase the service life of the battery.
