Accu VTC6 18650 - 30A 3000mAh

MURATA's VTC6 18650 BATTERY, historically marketed under the SONY brand, is a rechargeable lithium-ion cell particularly appreciated for its excellent balance between battery life and discharge capacity.

With a minimum capacity of 3000 mAh, an advertised nominal capacity of 3120 mAh and a specified maximum continuous current of up to 30A from MURATA, the VTC6 is a high-performance solution for electronic devices explicitly compatible with 18650 batteries.

Often commercially referred to as a 3.7V battery, its official nominal voltage is 3.6V, with a maximum charging voltage of 4.2V.

🔋 3000 mAh capacity for excellent battery life

The VTC6 has a guaranteed minimum capacity of 3000 mAh, while MURATA specifies a typical nominal capacity of 3120 mAh.

This substantial energy reserve is one of the VTC6's main advantages and provides comfortable battery life in a compact 18650 format.

Actual battery life naturally depends on several factors:

• Power used
• Device type
• Frequency of use
• The device's electronic efficiency
• The battery's condition and age

The VTC6 therefore represents an excellent compromise for users seeking more battery life than with 2500 or 2600 mAh 18650 cells.

⚡ Advertised maximum continuous current of up to 30A

The current MURATA catalog indicates for the US18650VTC6 a maximum continuous discharge current of 30A.

This high discharge capacity enables the cell to meet the needs of many compatible devices, provided that the device manufacturer's specifications and the safety rules specific to lithium-ion batteries are followed.

It is strongly recommended to always maintain a safety margin and never exceed the limits specified for the equipment used.

⚙️ 18650 format and Flat Top terminal

The VTC6 uses the widely adopted 18650.

Its official maximum dimensions are approximately:

• Diameter: 18.5 mm
• Length: 65.2 mm
• Weight: approximately 46,6 g
• Positive terminal: Flat Top

This format is used by many electronic boxes and other devices compatible with removable 18650 cells.

Before purchasing, always check that your device supports the 18650 format.

🔬 NCA lithium-ion technology

The VTC6 uses lithium-ion technology with an NCA-type cathode and an anode combining graphite and silicon, among other materials.

Its main technical specifications are:

• Model: US18650VTC6
• Format: 18650
• Minimum capacity: 3000 mAh
• Typical nominal capacity: 3120 mAh
• Nominal voltage: 3.6V
• Maximum charging voltage: 4.2V
• Stated maximum continuous current: 30A
• Weight: approximately 46,6 g
• Positive terminal: Flat Top
• Unprotected rechargeable cell

🔌 Recharging with a compatible charger

The VTC6 must be recharged with equipment specifically intended for 18650 lithium-ion cells.

MURATA specifies a reference constant-current / constant-voltage charge up to 4.2V.

To preserve the battery’s performance and lifespan, it is recommended to use a quality charger capable of properly controlling the charging voltage and current.

Using a suitable external charger is particularly convenient for users with multiple batteries.

🛡️ Unprotected battery: essential precautions

The VTC6 is a lithium-ion cell unprotectedIt must therefore only be used in a suitable device with the necessary safety protections.

For safe use:

• Never carry the battery loose in a pocket or bag
• Always use an insulated carrying case
• Avoid any contact with keys, coins, or metal objects
• Never use a battery with a torn wrap
• Do not use a deformed or damaged cell
• Do not expose the battery to excessive heat
• Never puncture or crush the cell
• Always observe the polarity
• Use only a charger suitable for lithium-ion batteries

A short circuit between the terminals can cause an extremely rapid rise in temperature and pose a serious risk.

🔄 Use in a multi-battery box

In a device operating with two or more batteries, it is recommended to use identical cells with the same usage history.

The set of batteries should ideally be:

• Of the same brand
• Of the same model
• Purchased at the same time
• Used together
• Recharged together
• With a similar level of wear

This practice helps maintain more consistent behavior between the different cells.

💡 When should a VTC6 be replaced?

Like all rechargeable Lithium-ion batteries, the VTC6 gradually loses capacity over the course of its charge cycles.

It is recommended to replace the cell in the event of:

• Significant reduction in battery life
• Abnormal heating
• Physical deformation
• Corrosion
• Damaged terminal
• Unusual behavior during charging
• Significant damage to the insulating wrap

A battery that has reached the end of its service life must be taken to a designated battery and accumulator collection point.

🎯 Who is the VTC6 battery for?

The MURATA VTC6 18650 BATTERY is intended for users of devices explicitly compatible with removable 18650 cells and equipped with suitable electronic protections.

It is particularly suitable for:

• For users looking for a capacity of around 3000 mAh
• For owners of devices compatible with 18650 batteries
• For users wishing to have a replacement battery
• For those looking for a good compromise between battery life and discharge capacity
• For users wishing to build a rotation of several batteries

⭐ MURATA VTC6 – battery life and performance in the 18650 format

With a minimum capacity of 3000 mAh, a nominal voltage of 3.6V, and a stated maximum continuous current of up to 30A, the VTC6 is a high-performance and versatile 18650 cell.

Formerly associated with SONY and now listed by MURATA under the designation US18650VTC6, it offers an excellent balance between battery life and performance for compatible devices, provided that the specific precautions for unprotected Lithium-ion cells are strictly followed.
