Office Chair Battery

The types, characteristics, and usage precautions of office chair batteries are as follows:

I. Power Supply Mode Classification

1. External Power Supply Type
   Mainstream electric office chairs adopt this mode, directly connecting to a socket via a power cord for power supply. Functions such as backrest lifting and rotation require continuous power and do not need charging. This design offers high stability but relies on a fixed power source, resulting in poor portability, and is suitable for long-term fixed workstation scenarios.

2. Built-in Battery Type
   A few high-end portable models (such as gaming chairs and executive chairs with wireless charging trays) are equipped with lithium-ion batteries, similar to mobile phone batteries. They require charging every 2-3 months and can last for 30-50 hours on a single charge. Battery models vary significantly depending on the brand, model, and application scenario, with common types including:

   • Lithium Batteries: 18650, 2650 cylindrical batteries, or soft-pack lithium batteries, mostly with voltages of 3.7V/7.4V and capacities ranging from 500mAh to 5000mAh.
   • Customized Battery Packs: Some brands use 18650 lithium battery packs with a voltage of 3.6V and a capacity of 2000mAh, which need to be replaced by matching the original parameters.

II. Usage and Maintenance Points

1. Safe Layout
   For office chairs with built-in batteries, pay attention to the layout of the power cord to avoid short circuits caused by the cord being crushed by the chair's wheels. If not in use for a long time, it is recommended to charge and discharge the battery every quarter to maintain its activity and prevent capacity degradation.

2. Battery Replacement Specifications
   Smart chair batteries are mostly custom-packaged and not universal models. When replacing, strictly match the original parameters (voltage, capacity, interface type). Mismatched voltages may cause equipment damage or safety hazards.

3. Charging and Storage Environment

   • Temperature Control: The charging temperature of lithium batteries should be between 0-45℃ to avoid performance issues caused by high or low temperatures.
   • Avoid Overcharging and Over-discharging: Long-term full charge or deep discharge states can accelerate battery aging. It is recommended to charge as needed and maintain the battery level between 20%-80%.

III. Suitable Scenario Recommendations

• External Power Supply Type: Suitable for fixed office scenarios, eliminating concerns about battery life and offering lower costs.
• Built-in Battery Type: Suitable for scenarios requiring flexible movement (such as conference rooms and home offices), but requiring regular battery maintenance.

Summary: The choice of office chair batteries should consider usage scenarios and maintenance costs. Built-in battery models, while portable, require attention to safety and maintenance, while external power supply models excel in stability. When replacing batteries, always follow the principle of parameter matching to ensure the safe operation of the equipment.
