What Size mAh e-Cig Battery?

The size or capacity of an e-cig battery refers to how much power it can store which affects how long it can be used before it needs to be recharged.

When it comes to the traditional standard e-cig battery, you will normally find the more power it can hold, the larger it will physically be.

However, e-cig batteries now come in many forms. You may have seen people using all sorts of interesting-looking devices, these also need their power source and this will either be a built-in battery which you will never see, or a conventional-looking battery that's inserted into an ecig battery tube or box shape device (these items are often referred to as mods).

Regardless of how the battery or power source may appear, when you see a number and mAh after it, it's giving you an indication as to the typical amount of power it can hold. This principal is similar to that of a fuel tank in a car, the bigger the tank, the further you can drive.

This is a guide to typical use for different mAh STANDARD/TRADITIONAL e-cig batteries:

Typical use between charges      Typical Usage                           Typical Puffs

320 mAh                                   half a day / 2-3 hours                350 puffs

650 mAh                                   1 day / 5-6 hours                      650 puffs

900 mAh                                   1.5 days / 8-9 hours                  900 puffs

1000 mAh                                 1.5-2 days / 10-11 hours          1000 puffs

1100 mAh                                 1.5-2 days / 10-11 hours          1100 puffs

1300 mAh                                  2 days / 14-15 hours               1300 puffs

1650 mAh                                  2-2.5 days / 15-16 hours         1650 puffs

2200 mAh                                  2.5-3 days / 20-22 hours         2200 puffs

* If you're a very heavy user your battery will drain faster and where a battery might typically last 8 hours, it may only last 4 hours.

* More complex devices, such as batteries or mods with multiple user features and different modes, such as temperature control, and high output devices, will use more power than a standard ecig battery.

What does 650mAh, 900mAh and 1100mAh mean?

650mAh v 900 mAh - what's the difference?

The mAh stands for milli Ampere hour or milli Amp hour. It’s the measure of a battery's energy storage capacity.

Imagine your battery as a fuel tank in a car, the mAh is the measure of how much fuel the battery can hold. The higher mAh rating the more fuel the battery can store inside. The more fuel, the longer the journey lasts.

And to put it another way, it’s how many puffs you can take before the battery needs to be recharged.

Slender e-cigarettes have batteries ranging anything from 90mAh to 360mAh and these smaller batteries need to be recharged more often.

In order to make a meaningful comparison, it’s important to compare mAh ratings of similar batteries. For example, there’s no point comparing an alkaline battery to a NiMH (nickel-metal hydride cell) battery. So assume we are talking about batteries that are similar, in this case lithium ion e-cig batteries.

Lithium batteries are used in e-cigarettes because they have good energy density and they’re slow to lose their charge when they’re not in use.

So we know that the mAh relates to the amount of fuel a battery can store, so the higher the number, ie 650mAh, 900mAh, 1100mAh, etc, we know that these batteries will last longer because they can store more energy.

If you're new to e-cigs, a 650mAh battery is a good one to start with and is the most common size battery you'll find in a starter e-cig kit. You can easily upgrade to a longer-lasting whenever it suits you.

Do bigger batteries produce more vapour?

The vapour is mainly dependent on the e-liquid and using the right battery with the right atomizer (and the heating elements in the atomizer). If you have a more powerful battery it generally means that the battery will last longer between charges, not that you will be getting more vapour. A variable voltage battery will allow for the adjustment of more or less vapour, but it is still the liquid and the kit (atomizer/coils for example) that primarily produce the vapour.
