How to Pick the Proper Vaping Battery

When choosing a vaping battery, we should always read the battery specifications carefully to see the discharge rate, capacity, cycle life, protected or unprotected, battery size and more. Here we would explain more for the most important parameters.

Maximum continuous discharge rate: the amp rating, also called CDA, which is what we want to know first. This indicates how quickly the battery can release its energy. The higher the discharge rate, the more power the battery can deliver. A discharge rate of at least 20A is recommended for most vaping devices.

Capacity: the mAh rating. This refers to the amount of energy that the battery can store. The higher the capacity, the longer the battery will last between charges. A capacity of at least mAh is ideal for most vapers.

We all want the longest vape time, but high mAh ratings usually come with lower amp ratings. So we need to find a balance between them based on our vaping needs.

The temperature limit is also a crucial specification to consider when selecting a vaping battery. Most batteries have a temperature limit of around 70-80 degrees Celsius (158-176 degrees Fahrenheit). It’s important to note that the battery temperature can increase significantly during use, especially if you are vaping at high wattages or using sub-ohm coils. So, it’s recommended to use batteries that have a higher temperature limit and to take regular breaks between vaping sessions to allow the battery to cool down.

Brand reputation is also an important factor to consider, as reputable brands are more likely to use high-quality materials and adhere to strict quality control standards. It’s also important to ensure that the battery is compatible with your vaping device, as not all devices support all battery sizes or types.

vs in Vaping

Most of the vaping mods currently on the market are compatible with two battery sizes – the and batteries. There are a few key differences that are worth considering.

One of the biggest differences between and batteries is their size. batteries are larger in size and have a higher capacity, typically ranging from mAh to mAh. In contrast, batteries are smaller and have a lower capacity, usually ranging from mAh to mAh. So, due to their larger capacity, batteries can provide longer vaping times between charges.

Another important difference is their discharge rate. batteries typically have a higher discharge rate, with many offering a maximum continuous discharge rate of 30A or higher. This makes them better suited for high-powered vaping devices, such as sub-ohm tanks or rebuildable atomizers.

On the other hand, batteries are more widely available and can be found in a wider range of devices. They are also typically more affordable than batteries.

Ultimately, the choice between and batteries comes down to your personal vaping needs and preferences. If you’re looking for a high-capacity battery with a high discharge rate, then a battery may be the best choice for you. If you’re looking for a more affordable option that is widely available and can be used in a wider range of devices, then an battery may be a better choice.

How long do batteries last for in vaping?

The original cycle life of batteries is typically around 500- cycles. In a typical vaping device, a fully charged battery with a capacity of mAh can last anywhere from 5-10 hours of continuous use, depending on the device’s power output and the user’s vaping habits.

However, several factors can affect the battery life and discharge, including the frequency of use, the level of discharge between charges, and the charging practices. The more frequently a battery is discharged and recharged, the faster its cycle life will degrade. Also, if a battery is discharged too deeply or charged too quickly, it can shorten the battery life.

And, low resistance coils used at a high wattage will drain your battery faster.

Unprotected or Protected for Vaping

Batteries can be classified into two categories: protected and unprotected. Protected batteries are equipped with a circuit that prevents overcharging, over-discharging, and short circuits. Unprotected batteries lack these protective circuits, which makes them more prone to accidents if not handled correctly.

Which one is best for your vaping device? The answer is the unprotected cells. Protected batteries are typically described as “high-capacity” batteries. Their amp rating is usually at 10 amps or even lower, and they are commonly used for household flashlights, radios, and other similar devices. However, their CDR is too low for most of our vaping requirements. On the other hand, unprotected batteries are typically “high-drain” batteries with a CDR of at least 15 amps. These batteries are designed for high-energy devices such as vaping, portable power tools, or high-intensity flashlights.

If you come across a blog or article that recommends using protected cells for vaping, it is outdated. Earlier battery uses mostly ICR chemistry, which were commonly made into batteries with protection boards. With the advancement of technology, nowaways the lithium ion batteries use IMR/INR/NCR chemistry, which is safer than ICR batteries.

Best Vape Battery Chargers and Charging Method

A high-quality charger is very important for vapers. This will ensure safe and efficient charging, and also help to extend the lifespan of your batteries. Here we recommend XTAR chargers.

XTAR is a reputable brand in the vaping industry, and they offer several chargers that are suitable for batteries. The following are three of the best XTAR chargers for  vape batteries:

XTAR PB2S – The XTAR PB2S is a portable charger that can charge up to two batteries simultaneously. It has two USB outputs, allowing you to charge your vaping mods and phones at the same time. The PB2S also has a display that shows the charging status of each battery, as well as the voltage and charging current. It supports QC3.0 and PD3.0 dual charging and discharging with max 2A current.

XTAR VC4SL – The XTAR VC4SL is a four-bay smart charger that is capable of charging multiple batteries at once. It has a clear LCD screen that displays the charging status of each battery, including the battery internal resistance. The max charging current reaches up to 3A for a slot. It also features actual capacity test and best storage voltage adjusting function.

XTAR VC8 – The XTAR VC8 is an eight-bay charger that is designed for multiple battery users. It is equal to the two VC4SL chargers. USB-C input, max 3A charging for a single slot. You can also test the real battery capacity and adjust the storage voltage.

Smart XTAR chargers can automatically detect your battery status and uses the optimal charging current. They use the TC-CC-CV charging method in the purpose of charging safety and prolonging battery life.

If you prefer to control the charging current by yourselves, you need to calculate the best charging current based on the capacity of your battery.

Using and Storage Safety for Vaping Battery

Safety is always a big topic for vapers, especially in battery using and storage. Here are some important tips to keep in mind:

► Use the right charger designed for your battery.

► Charge your battery properly and do not leave it unattended.

► Avoid exposing the battery to extreme temperatures or moisture.

► Store the battery in a cool and dry place, away from metal objects and keys.

► Check the battery for damage, especially the battery wrap, to aviod a short circuit.

Over-Discharged Batteries

Over-discharging means draining the battery beyond its safe minimum voltage level. The end-of-discharge voltage usually is 2.5V.

If your battery is over-discharged, you should not attempt to use it until you have recharged it. Using an over-discharged battery can lead to permanent damage to the battery or even cause it to catch fire.

To bring an over-discharged battery back to life, you can try using a specialized charger with reviving function. These chargers can bring the battery back to a safe voltage level and restore its performance. However, if the battery is severely damaged or has been over-discharged multiple times, it may not be possible to revive it, and you will need to replace it.

To preventing over-discharge, you need to avoid leaving your batteries unused for extended periods and not using them beyond their capacity. It’s also essential to use a battery with a suitable CDR rating for your vaping device and not exceed the recommended wattage or voltage level. Additionally, using a device with a battery monitoring system can help prevent over-discharge by shutting off the device before the battery reaches a dangerously low voltage level.

Disposal of Dead Batteries

Proper disposal and recycling of dead batteries is an important aspect of being a responsible battery user. When a battery is no longer holding a charge or is damaged beyond repair, it should not be thrown in the regular trash.

There are several ways to properly dispose of dead batteries. One option is to take them to a local recycling center or a store that offers battery recycling programs.

Another option is to participate in mail-in battery recycling programs. Many battery manufacturers and retailers offer these programs, where you can send in your used batteries in a pre-paid mailer for safe disposal.

As a responsible battery user, it is important to also consider the impact of your overall battery usage on the environment. Avoiding over-discharging and overcharging your rechargeable batteries can help prolong their lifespan and reduce the frequency of replacements.
