Li-ion Rechargeable Battery 18500 3.7V 1200mAh

Li-ion Rechargeable Battery 18500 3.7V 1200mAh

The Li-ion 3.7V Rechargeable 18500 1200mAh battery is a cylindrical lithium-ion battery that operates at a nominal voltage of 3.7 volts, commonly used in portable electronic devices. It has a capacity of 1200mAh (milliampere-hour), which defines how much charge the battery can store, allowing for extended usage before needing to be recharged.

Key Features:

• Voltage: 3.7V nominal, which is typical for most small rechargeable devices.
• Capacity: 1200mAh, offering a decent charge for medium-power devices or those with lower energy consumption.
• Rechargeable: Can be recharged many times (up to 500–1000 cycles, depending on usage), making it cost-effective and environmentally friendly.
• Size: The 18500 size refers to the physical dimensions of the battery (18mm in diameter and 50mm in length), similar to the 18650 size but slightly smaller.
• Lithium-ion Chemistry: Offers a higher energy density, longer life, and lighter weight compared to older battery types like nickel-cadmium (NiCd).
• Low Self-Discharge: Li-ion batteries have a low self-discharge rate, which means they hold their charge for a longer period when not in use.
