How to Distinguish 1.5V Rechargeable Lithium, NiMH, Alkaline and Disposable Batteries
Although all labeled 1.5V batteries may look similar, their internal chemistry, performance, lifespan, and cost can be vastly different. In this guide, Huawen New Power helps you clearly understand how to identify and compare lithium, NiMH, alkaline, and disposable lithium batteries — and why rechargeable lithium batteries are becoming the new standard.
Battery Type Overview
🔋 Rechargeable Lithium (1.5V)
Constant output, USB charging, 500–1000 cycles. Great for modern devices.
🔄 NiMH (1.2V)
Rechargeable but lower voltage. Incompatible with some electronics.
⚠️ Alkaline Battery
Disposable, voltage drops fast. Inexpensive, but not eco-friendly.
🧪 Disposable Lithium
Stable performance, but single-use and high cost. Ideal for medical/special use.

3. Long-Term Cost Comparison
Note: One rechargeable lithium battery can replace 500+ alkaline batteries over its lifespan — saving both cost and waste.
4. Identification Tips
Rechargeable Lithium: Labelled "1.5V Rechargeable", often with USB port.
NiMH: Labelled "1.2V NiMH", no USB, charger required.
Alkaline: Marked "Alkaline", disposable only.
Disposable Lithium: Marked "Lithium", not rechargeable.
