Ampere Hour (Ah)

Have you ever wondered what makes certain e-cigarette batteries last longer than others? Or why some batteries offer a more powerful vaping experience? The answer lies in one term: Ampere Hour (Ah). By understanding Ah, you'll be able to choose batteries that perfectly cater to your vaping needs, guaranteeing an optimised, safer, and more satisfying experience. Whether you're just starting out or you're a seasoned vaper, mastering the knowledge of Ampere Hour can escalate your vaping satisfaction to the next level.

What Is an Ampere Hour (Ah)?

Ampere Hour (Ah) is a unit of measurement that describes the energy charge that a battery will hold. It indicates the amount of current a battery can supply over an hour at a specific voltage.

When it comes to e-cigarettes, understanding the Ampere Hour rating can help determine how long your battery will last before it requires recharging. For example, a battery with a higher Ah rating will typically last longer than one with a lower rating, assuming they're used at the same wattage. Choosing a battery with an appropriate Ah rating can help you optimise your vaping experience based on your usage habits.

Types of Batteries

E-cigarettes typically use rechargeable Lithium-Ion (Li-ion) batteries. They are favoured for several reasons, including their ability to recharge quickly, their long lifespan, and their capacity to handle the high current requirements of most vaping devices.

Let's discuss the different types of batteries for e-cigarettes, with Ampere Hour (Ah) being the significant factor. 

Low capacity batteries (up to 800mAh): These batteries are compact and lightweight, often used in smaller e-cigarettes. Due to their lower Ah rating, they don't last as long and are more suited to infrequent vapers who prefer a smaller, more discreet device.

Medium capacity batteries (800mAh to 1500mAh): These types of batteries offer a good balance between size and battery life. They are typically used in pen-style e-cigarettes and pod devices. They are suitable for moderate vapers, as they can generally last through a day of vaping.

High capacity batteries (above 1500mAh): Batteries with high capacity are designed for heavy vapers and are often used in more powerful devices like mods and sub-ohm devices. Thanks to their high Ah ratings, they often last several days before needing to be recharged. 

Understanding your unique vaping habits and lifestyle needs can help you determine which battery capacity might be most beneficial for you. 

How to choose the right type of batteries?

If you want to enhance your vaping experience, choosing the right battery for your e-cigarette or vape can be one thing to look into. However, it involves understanding several factors:

Ampere Hour (Ah): This factor reflects battery life. If you are a heavy vaper, consider a high capacity (over 1500mAh) battery. For occasional use, a lower capacity battery (up to 800mAh) may be more than enough.

Voltage: The voltage of a battery affects the amount of vapour you can produce. Batteries with variable voltage allow you to control vapour production based on your preference.

Size and compatibility: It's also important to choose a battery that fits your device and is compatible with its specifications. Compatibility also extends to the resistance of your atomiser (measured in ohms), which can impact whether a battery can safely power the device.

Quality and safety: Always prioritise quality. Look for recognized safety certifications, protection features (like overcharge and short circuit protection), and buy from reputable sellers/brands.

Style of vaping: If you prefer DTL (direct-to-lung) vaping, consider batteries suited for sub-ohm vaping. If you prefer MTL (mouth-to-lung) vaping, a standard vape battery generally works just fine.

Rechargeable vs. disposable: While disposable batteries can be convenient, rechargeable batteries offer repeated use and are more environment-friendly.

Battery safety

We can't possibly talk about batteries for your e-cigarettes without mentioning battery safety. A reliable, well-maintained battery is key to ensuring a satisfying and secure vaping experience. Misuse can lead to battery failure, which, in worst-case scenarios, can cause injury or damage to your device.

So, as we mentioned previously, if your vaping device requires a high current drain, you'll need a high-capacity battery. Using a low-capacity battery can strain the battery, impacting its lifespan and potentially creating a safety risk. However, a high-capacity battery isn't necessarily better for every vaper; if you vape sporadically, a lower-capacity battery will be more suitable.

Here are some tips to ensure battery safety:

  • Make sure your battery is compatible with your device, particularly in terms of Ah rating and voltage output.
  • Frequently inspect your batteries for signs of damage or leaking. If you notice anything unusual, replace the battery.
  • Store your batteries properly. Never carry loose batteries in your pocket or bag, as they can come into contact with other metal items causing a short circuit.
  • Avoid exposing them to extreme temperatures. High temperatures can cause the battery to overheat, while cold temperatures can reduce its performance. The best is to keep them at room temperature.
  • Only use the charger that comes with your battery or a certified replacement. 
  • Overcharging can degrade your battery. Therefore, avoid leaving it to charge overnight or beyond the recommended charging time.

What mAh is best for vaping?

It's difficult to say what the best mAh rating for vaping is. It mainly depends on your vaping habits. If you are a heavy vaper, you should go for a high mAh battery (over 1500mAh) for longer use. However, if you are more of an occasional vaper, a lower mAh battery (up to 800mAh) will be enough for you.

Do vapes use AAA batteries?

No, vapes don't traditionally use AAA batteries. Most vape devices use specific rechargeable Lithium-Ion (Li-ion) batteries, which are designed to meet the power requirements of e-cigarettes.

How do I choose the right vape battery?

Consider factors such as the Ampere Hour (mAh) rating, the voltage output, the compatibility with your device, the type of vaping you prefer, and the safety features provided. This should help you find the best battery for your needs.

What is the strongest vape battery?

One could say that the 'strongest' vape battery would be one that offers the highest power output and the longest life, usually characterised by a high mAh rating and voltage. However, remember that this suitability is subjective and depends on your vaping preferences and patterns.
