What Voltages Do Batteries Come In?

🔋 Single-Cell Battery Voltages by Chemistry

Chemistry	Nominal Voltage	Fully Charged	Fully Discharged
Alkaline (e.g., AA)	1.5 V	1.5 V	~0.9 V
Zinc–Carbon	1.5 V	1.5 V	~0.9 V
Nickel-Cadmium (NiCd)	1.2 V	~1.4 V	~1.0 V
Nickel-Metal Hydride (NiMH)	1.2 V	~1.4 V	~1.0 V
Lithium-Ion (Li-ion)	3.6 or 3.7 V	4.2 V	~3.0 V
LiFePO₄ (Lithium Iron Phosphate)	3.2 V	3.6 V	~2.5 V
Lithium Primary (e.g., CR2032 coin cell)	3.0 V	3.0 V	~2.0 V
Lead-Acid (single cell)	2.0 V	2.1 V	~1.75 V
Zinc–Air	1.4 V	1.4 V	~1.1 V
Silver-Oxide (watch battery)	1.55 V	1.55 V	~1.2 V

🔋 Common Multi-Cell Battery Pack Voltages

These come from combining individual cells in series:

• 3.0 V – CR123 or two 1.5 V alkalines
• 4.8 V – 4 NiMH/NiCd cells
• 6.0 V – 4 alkaline cells or 3 LiFePO₄
• 7.2 V – 6 NiMH/NiCd or 2 Li-ion cells (7.4 V)
• 9.0 V – Standard 9V battery (6 x 1.5 V cells)
• 12.0 V – Lead-acid car battery (6 x 2 V)
• 14.4 V – 4-cell Li-ion
• 18.0 V – Power tools (usually 5 Li-ion cells)
• 24.0 V – Electric scooters or small systems
• 36.0 V / 48.0 V / 72.0 V – E-bikes and energy storage
• 96 V and higher – EVs and industrial systems
