Description - Vapcell U30 18650 3000mAh 30A Battery
The Vapcell U30 18650 3000mAh 30A Battery is a high-drain rechargeable lithium-ion cell designed for compatible vape mods that use removable 18650 batteries. Combining a 3000mAh nominal capacity with a manufacturer-rated 30A continuous discharge current, the U30 provides a balance of battery capacity and high-current performance for suitable regulated vaping devices.
The gold-wrapped U30 uses rechargeable INR lithium-ion chemistry and measures approximately 18.1mm x 65mm. Vapcell also specifies a maximum short discharge rating of up to 45A; this is a short-duration figure and should not be treated as a 45A continuous discharge rating.
Browse our full range of 18650 vape batteries or pair your cells with a suitable 18650 battery charger.

3000mAh Capacity for Everyday Vape Mods
The 3000mAh capacity of the Vapcell U30 offers a useful balance between runtime and discharge capability for compatible 18650 vape mods.
Battery life will depend heavily on your device, coil resistance, selected wattage and how frequently you vape. Lower power settings will generally provide longer runtime from a charge, while higher wattages place greater demand on the battery and reduce the amount of time between charges.
30A Continuous Discharge Rating
Vapcell rates the U30 for a 30A continuous discharge current, making it a high-drain 18650 cell intended for applications that require substantial current delivery.
The battery is also listed with a maximum 45A short discharge current. This higher figure applies only to short-duration discharge and should never be interpreted as a 45A continuous rating.
Always select a battery based on the continuous current requirements of your device rather than relying on a pulse or short-discharge figure.

What Vape Mods Are Compatible With the Vapcell U30?
The Vapcell U30 is designed for compatible devices that accept a removable flat-top 18650 lithium-ion battery.
Before using the U30, check your vape mod manufacturer’s specifications to confirm:
- The device accepts 18650 batteries
- The physical battery format is compatible
- The battery's continuous discharge capability is appropriate for the intended power level
- The battery wrap and insulator are completely undamaged
Do not assume that every device using an 18650-size cell has the same battery requirements. Battery choice should always be matched to the particular device and intended operating conditions.
Using the Vapcell U30 in Dual-Battery Mods
If you are using the U30 in a vape mod requiring two or more batteries, use a matched set of identical cells purchased and used together.
Do not mix batteries of different brands, models, capacities, ages or charge levels in the same multi-battery device.
Keeping batteries married as a set helps ensure the cells have experienced similar charging and discharge cycles throughout their working life.
How to Charge the Vapcell U30 18650 Battery
The U30 is a rechargeable lithium-ion cell and should only be charged using equipment suitable for rechargeable 18650 Li-ion batteries.
A dedicated external charger can make it easier to monitor removable cells individually. Browse our 18650 battery chargers for compatible charging options.
Vapcell specifies a standard charging current of 1.5A and a rapid charging current of up to 3A.
Vapcell U30 Battery Safety
Rechargeable 18650 lithium-ion batteries must be handled correctly. The Vapcell U30 is an unprotected cell with no built-in BMS protection circuit, so correct handling, storage, charging and device compatibility are essential.
- Never carry loose batteries in a pocket, bag or purse
- Always transport spare cells in a suitable protective battery case
- Keep batteries away from keys, coins and other metal objects
- Never use a battery with a torn or damaged outer wrap
- Check the positive-terminal insulator for damage
- Do not expose batteries to excessive heat
- Do not crush, puncture or intentionally short-circuit a cell
- Only use a charger suitable for lithium-ion 18650 batteries
- Ensure the battery is suitable for your particular vape mod
- Do not exceed the safe continuous current requirements of the cell
- Do not mix unmatched batteries in multi-cell devices
For more information before using removable cells, read the Vaping101 Vape Battery Safety Guide.
When Should I Replace My Vapcell U30?
Stop using an 18650 battery if you notice physical damage, a torn wrap, damaged insulator, unusual overheating, significant deterioration in performance or other signs that the cell may no longer be safe to use.
Never continue vaping with a physically damaged lithium-ion battery. Batteries that have reached the end of their usable life should be taken to an appropriate battery recycling facility rather than placed into normal household waste.
Who Is the Vapcell U30 18650 For?
The Vapcell U30 is best suited to users of compatible removable-battery vape mods who want a 3000mAh 18650 cell with a high manufacturer-rated discharge capability.
It may suit users who:
- Own a compatible 18650 vape mod
- Want a rechargeable removable battery
- Prefer a balance between capacity and discharge capability
- Use regulated single or dual 18650 devices
- Understand removable lithium-ion battery safety
If you are unsure whether this battery is suitable for your device, check your vape mod's manual or manufacturer specifications before use.
