### 智能门锁的电池痛点 / Smart Lock Battery Pain Points

智能门锁是家庭安防的核心设备，对电池可靠性要求极高。传统碱性电池在门锁场景下存在三大问题：漏液腐蚀电路板、电压下降导致门锁失灵、频繁更换电池影响使用体验。

Smart locks are core home security devices with extremely high battery reliability requirements. Traditional alkaline batteries have three major problems in lock scenarios: leakage corroding circuit boards, voltage drop causing lock failure, and frequent battery changes affecting user experience.

漏液问题尤为严重。碱性电池使用6-12个月后，内部电解液可能渗出，腐蚀门锁主板和电机触点，导致门锁损坏。一台几百元的智能门锁，可能因为几块钱的电池漏液而报废。

Leakage is particularly serious. After 6-12 months of use, alkaline battery electrolyte may seep out, corroding lock mainboards and motor contacts, causing lock damage. A smart lock worth hundreds of yuan could be ruined by a few yuan worth of leaking batteries.

### 1.5V锂电池的解决方案 / 1.5V Lithium Battery Solution

恒压输出：1.5V锂电池从满电到耗尽，输出电压始终稳定在1.5V左右，不会因电压下降导致门锁突然失灵。门锁电机和主板始终工作在设计的电压区间内。

Constant voltage output: 1.5V lithium batteries maintain stable output around 1.5V from full charge to depletion, preventing sudden lock failure due to voltage drop. Lock motors and mainboards always operate within designed voltage range.

不漏液设计：锂电池采用密封结构，无电解液泄漏风险，保护门锁电路板长期安全。

No-leak design: Lithium batteries use sealed structure with no electrolyte leakage risk, protecting lock circuit boards for long-term safety.

长循环寿命：充电1000次以上，按每天开关门10次计算，可使用3-5年。即使每天频繁使用，也无需频繁更换电池。

Long cycle life: 1000+ charge cycles, calculated at 10 door openings daily, can be used 3-5 years. Even with frequent daily use, no need for frequent battery changes.

### 选型建议 / Selection Recommendations

推荐型号：AA 1.5V锂电池2775mWh或3100mWh档位。2775mWh适合普通家庭使用，续航约12-18个月；3100mWh适合高频使用场景（如公寓、办公室），续航约18-24个月。

Recommended models: AA 1.5V lithium battery 2775mWh or 3100mWh tier. 2775mWh suits normal household use, 12-18 months runtime; 3100mWh suits high-frequency scenarios (apartments, offices), 18-24 months runtime.

充电方式：推荐Type-C直充版本，电池自带充电口，无需拆卸电池，直接用充电线为门锁充电，使用更便捷。

Charging method: Recommend USB-C direct charge version, battery has built-in charging port, no need to remove battery, charge lock directly with charging cable for more convenient use.
