ER34615 lithium sub-battery is a disposable lithium battery, after use is not rechargeable to use, forced to charge may cause serious accidents.
(1) In fact, the battery we usually describe no power is not no power, but the disposable battery after discharging the increase in internal resistance caused by the battery in the reaction of hydrogen gas gathered on the electrode surface to increase the resistance, if we do want to try to charge the disposable battery, it is not completely impossible, but we need to pay close attention to the heat of the battery, the disposable battery will increase the internal resistance after using electricity The heat generated during charging is also very high. Once found overheating, you must stop charging. Otherwise, it may explode and catch fire.
2) Common disposable batteries include alkaline manganese batteries, zinc manganese batteries, silver zinc batteries, zinc air batteries, zinc mercury batteries and magnesium manganese batteries. These batteries cannot be recharged and used twice. That is, they are used up and discarded.
3, the common secondary rechargeable batteries are lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-hydrogen batteries, lithium-ion batteries. The advantage is the long cycle life, can be used repeatedly. Now the longest service life of lithium batteries can theoretically reach 4000 times.
The difference between primary batteries and secondary batteries
There is a clear difference between primary and secondary rechargeable batteries in terms of application. Primary batteries are more suitable for use in extreme environments. The temperature resistance is stronger, so in some special communication fields, disposable batteries have the advantages that secondary batteries cannot replace. Secondary batteries can be recycled many times. However, they are less adaptable to extreme environments.
