Accu Sony VTC6A 21700 - 4000mAh 30A

SONY VTC6A 21700 4000MAH BATTERY is a rechargeable battery intended for electronic cigarettes and devices compatible with the 21700 size. With its generous 4000 mAh capacity and advertised maximum discharge current of up to 30A, it offers an excellent balance between battery life and performance.

Its 21700 size provides greater capacity than many 18650 batteries while maintaining performance suitable for electronic cigarettes requiring a stable power supply. Its INR Lithium-ion chemistry and Flat Top positive terminal make it a versatile choice for compatible devices.

🔋 4000 mAh capacity for extended battery life

The VTC6A offers a nominal capacity of 4000 mAh, particularly comfortable for users seeking good battery life.

Compared with many lower-capacity 18650 batteries, the 21700 size reduces the frequency of recharging, particularly when the electronic cigarette is used at moderate power.

Actual battery life naturally depends on several factors:

• The power used
• The resistance value
• The frequency of inhalation
• The device's chipset
• The battery's condition and age

Its 4000 mAh capacity nevertheless makes it an excellent choice for everyday use with a compatible 21700 device.

⚡ Advertised maximum discharge up to 30A

The VTC6A is marketed with an advertised maximum discharge current of up to 30A.

This characteristic enables the battery to meet the needs of many electronic devices compatible with the 21700 size.

For safe use, it is essential to respect the battery's limits and the recommendations of your electronic cigarette manufacturer.

Since maximum or continuous current values may be presented differently across commercial technical specifications, it is recommended to always prioritize use with an appropriate safety margin.

⚙️ 21700 size and Flat Top positive terminal

The VTC6A uses the standard 21700, with a diameter of approximately 21 mm and a length close to 70 mm.

Its positive terminal is a Flat Top, without a protruding button.

It is intended for devices explicitly compatible with 21700 batteries.

Before purchasing, always check the size supported by your device: a 21700 battery is larger than an 18650 battery and therefore cannot be installed in all devices.

🔬 INR Lithium-ion chemistry

The VTC6A is based on INR / Lithium-ion rechargeable chemistry.

Its main features are:

• Capacity: 4000 mAh
• Size: 21700
• Nominal voltage: 3.7 V
• Maximum charging voltage: 4.2 V
• Advertised maximum discharge current: 30A
• Positive terminal: Flat Top
• Rechargeable battery

This combination provides a good balance between energy capacity and performance.

🔌 Recharge with a suitable charger

To preserve the battery’s performance and lifespan, using an external charger compatible with 21700 batteries is recommended whenever possible.

The charger must be suitable for Lithium-ion cells and comply with the maximum voltage of 4.2 V.

Before each recharge, it is important to visually check the battery’s condition, especially to ensure that its insulating wrap is not damaged.

A battery with a torn wrap, damaged insulation or deformation must not be used until it has been properly restored or replaced.

🛡️ Transport and storage: essential precautions

A 21700 battery must always be handled with care.

To prevent short circuits:

• Never carry a loose battery in a pocket
• Avoid any contact with keys, coins or metal objects
• Always use an insulating box or case
• Never puncture the battery
• Do not expose it to excessive heat
• Do not use a damaged battery
• Observe the polarity when installing it

Simultaneous contact between both terminals and a metal object can cause a short circuit and a rapid rise in temperature.

🔄 Ideal as a main or replacement battery

The VTC6A 21700 can be used as the main battery in a compatible device or as a replacement battery.

Its 4000 mAh capacity makes it particularly suitable for users who want to have several batteries and rotate the cells while recharging.

For devices operating with multiple batteries, it is recommended to use identical batteries purchased and used together, with a comparable level of wear.

🎯 Which users is it intended for?

THE VTC6A 21700 4000MAH BATTERY – SONY is intended for users who own an electronic cigarette or device explicitly compatible with 21700 batteries.

It is particularly suitable for:

• Users looking for long battery life
