Charge-Discharge Cycle Times
**Principle:** During each charge-discharge cycle of lithium batteries, a series of chemical reactions occur within the battery's internal components. As the number of charge-discharge cycles increases, the structure of the electrode materials gradually changes, leading to a reduction in battery capacity. For instance, common lithium batteries may experience a decline in initial capacity from 100% to below 60% after a certain number of cycles, significantly impacting their performance.


**Degree of Influence:** The service life of batteries is closely linked to their charge-discharge cycle count. Generally speaking, lithium batteries can endure approximately 500 to 1,000 cycles (with variations depending on battery type). Frequent charging and discharging during daily use—such as operating the tea-picking machine multiple times per day—can shorten battery lifespan.


**Charging Methods and Habits**
**Charging Method:** Utilizing an inappropriate charger or charging method can adversely affect battery longevity. For example, employing a high-current charger that does not meet specified requirements may lead to overcharging, generating excessive heat within the battery and accelerating aging and decomposition processes for its internal chemical substances.


**Charging Habit:** Overcharging or deep discharging habits also contribute to battery damage. Leaving batteries connected to chargers for extended periods can result in an overcharged state; conversely, consistently allowing them to discharge nearly completely before recharging leads to irreversible loss of active materials on the plates—both scenarios ultimately reduce overall lifespan.


**Working Environment Temperature**
**High-Temperature Environment:** Operating or charging batteries in elevated temperature conditions accelerates internal chemical reaction rates while hastening self-discharge processes and causing evaporation and decomposition of electrolytes. For example, when ambient temperatures exceed 45°C (113°F), aging rates increase significantly alongside accelerated capacity attenuation.


**Low-Temperature Environment:** Conversely, low-temperature environments diminish chemical activity within batteries resulting in reduced output power and available capacity. Additionally ,frequent cycling at low temperatures risks damaging both electrode materials and electrolytes .For instance ,when temperatures drop below 0°C (32°F) ,battery performance suffers considerably with prolonged exposure leading directly towards shortened lifespans .


**Usage Intensity and Load Conditions for Batteries**
**Usage Intensity:** If Dehua’s lithium-battery tea-picking machines are frequently operated continuously under high-load conditions ,the consumption rate among chemicals inside will accelerate thereby shortening overall service lives .For example,a tea-picking machine utilized several hours daily across expansive gardens experiences greater wear compared against one used sporadically .


**Load Conditions : **The magnitude associated with loads such as motors connected directly impacts longevity too .If motor specifications exceed optimal limits large currents generated during start-up/running phases impose significant strain upon cells resulting premature degradation along with rapid depletion regarding active constituents further diminishing expected operational duration .


**Battery Quality & Maintenance Status**
**Battery Quality : **Intrinsic quality remains pivotal influencing durability ;higher-grade units exhibit superior component integrity including electrodes/electrolytes capable enduring more extensive cycling amid challenging settings .Should Dehua employ premium raw materials coupled advanced manufacturing techniques throughout production lines then resultant products yield enhanced reliability/longevity assurances .

**Maintenance Status : *Regular upkeep practices like surface cleaning/checking connections extend usable lifetimes substantially whereas neglect invites dust accumulation/loose fittings potentially culminating failures/performance declines.
