ML2032 Lithium Battery Related (2025-01-01)
- ML2032 3V就是可充電版本的CR2032，但是電池好找，充電器難找
- ML2032 是 3V 不可與 LIR2032 3.7V混用充電座，最高電壓完全不同，
- LIR2032 3.7V完全是鋰電池 3.7V為起，充飽為4.2V，如果設備對於電壓敏感的可能會燒毀或者不動
Reference
-
- 根據Maxcell關於ML2032的文檔，ML2032的充電電壓不得超過3.3V。負極上的電壓始終等於正極上的電壓減去ML2032 的電壓，因此施加到連結電池的電壓不會超過 3.3 V（如果電池沒有過度充電）。
-
- 我使用下面的電路為 LED 提供恆定電流。我請求您就如何計算僅由溫度引起的電流容差（設定電流的最小和最大變化）提出建議。
- 如何考慮變化V是
- 計算電流？
