This is the same Aspire K4 battery that comes with the K4 Quick Start Kit.
It can be used with different tanks, 22mm being the ideal diameter. These batteries can also handle sub-Ohm coils as the K4 kit includes 0.27 Ohm Cleito coils which are rated 40-55W. We do not know the minimum resistance capability so do not go lower than 0.27 Ohm unless you know otherwise and bear in mind the wattage range of the Cleito coils it's designed for us with.
The packaging comes with authenticity hologram and scratch panel.
1 x Aspire K4 battery 2000mAh
1 x User leaflet
For more information about eGo style and 510 style battery capacities, ie 900mAh, 1000mAh etc, and how long they last between charges, please see our article called what size mAh battery.
Users of electronic cigarettes must be very cautious when charging and using all types of rechargeable lithium-ion batteries and this includes built-in mod batteries.
If misused, mistreated or mishandled, lithium-ion batteries pose a serious safety issue.
Please familiarise yourself with best practice and play it safe.
We will not be held responsible for damage if there is any modification of the batteries or chargers in any form.
We are not responsible for any damage or injury caused by the misuse, mishandling or mistreatment of lithium-ion batteries and/or chargers.
All lithium e-cig batteries need to have some charge in them to stay healthy, so they come part charged and ready to use.
The first time you recharge your battery ensure you give it a full charge which could take 4-5 hours, depending on the battery.
Don't overcharge the battery, when it's charged and the light on the charger indicates charged, remove the battery from the charger.
If you're using a mod with removable batteries, the manufacturer often recommends that it is advisable to remove the batteries and to charge them separately, ie don't charge them in situ via the USB.
Storing batteries properly extends the life of the battery and keeps them from becoming a safety hazard.
Good clean contact between your e-cig battery and clearomizer/tank is essential for the best heat, vapour and flavour, so regular cleaning is essential (every couple of weeks or so for example).
Rubbing alcohol/surgical spirit on a Q tip/cotton bud is ideal. Clean the outside of the connection/contact area (for eGo batteries) and the inside too ensuring that you hold the battery upside down so gravity can take away any excess fluid. Paper towel can be used to dry the area if necessary.
For stubborn grime a cocktail stick is ideal for the threaded grooves, taking care not to break it off inside the battery, but don’t use anything metal.
Batteries are tested before they leave the manufacturer but this doesn’t mean there will never by a faulty battery in circulation. However, if you’re having problems with a battery (and it’s relatively new) there are other things to consider and eliminate.
If you’ve purchased batteries from one source and chargers from another there may be a compatibility problem, ie a slight difference in the size of the battery thread and the tank device or, and this is much more serious, the charger may not be intended to charge your particular e-cig battery and there may be voltage issues and therefore a serious safety risk.
Use special caution when working with e-cigarette batteries as they are very sensitive to charging characteristics and may overheat or explode if mishandled or misused.
The user must ensure they have sufficient knowledge and take sufficient care in charging, discharging, assembly and storage.
Healthy Start Ltd is not responsible for damage if there is any modification of the batteries or chargers nor is Healthy Start Ltd responsible for any damage caused by the misuse and/or mishandling of any batteries and chargers.
Healthy Start Ltd will not be held responsible or liable for any injury, damage, or defect, permanent or temporary that may be caused by the improper use, due care and attention and storage of batteries.
Use this link for our returns and refunds policy.
Electronic Cigarette Co (Healthy Start Ltd) offers the original buyer product warranties as set out below, which become effective from the date of purchase. During the warranty period, we will, at our discretion, repair or replace items that are defective.
These warranties give the purchaser specific limited rights, in addition to those rights under applicable local law. There are one or two exceptions, therefore, if an individual product page on our website stipulates a specific longer or shorter warranty period, that warranty takes precedent over those below.
Our warranties never provide cover for physical damage, misuse, or breakages.
Scratches and discoloration from regular use is considered normal wear and tear and is not covered by warranty.
Manufacturers are likely to require their serial number before providing a replacement item. This is due to the increasing amount of counterfeits in circulation. Please keep your packaging with the serial number, or take pictures of it before you discard it.
Rechargeable e-cigarette batteries, both eGo and 510 style, come with a 28 day warranty and have a life expectancy of anything from 3 - 9 months, depending on usage and brand. The guarantee covers any manufacturing defects and any repairs, or replacements, if deemed to be faulty or beyond repair. The warranty doesn't provide for physical damage, misuse, or general wear and tear. Ensure you treat your battery well. Click here for our e-cig battery problems page for further information.
USB chargers, wall chargers, USB car chargers and other battery chargers are covered by warranty for a period of 28 days. Physical damage, misuse, and general wear and tear are not covered.
These are consumable items lasting anything from a few days to a couple of months and there is no warranty applicable. Issues with coils are often caused by improper priming, letting the tank run low or drawing too frequently. Please click here for more information about how to prime e-cig coils correctly and it will guide you through to coils burning too.
These items are non returnable and are not covered by warranty but defective items will be refunded or replaced.
Defective liquids will be replaced or refunded. This applies to e-liquid that is out of date or has a manufacturing defect.
The kits comprise many parts and it's the individual parts that would be subject to their individual warranty cover, for example, an eGo or 510 style battery will usually be 30 days. Physical damage, misuse, or general wear and tear is not covered.
These consumable items are not covered by a warranty. Expect a typical lifetime of 300 charges when used properly.
Box mods are covered for 90 days from date of purchase. The guarantee covers manufacturer defects and any repairs, or replacements, if deemed to be faulty or beyond repair. The warranty does not cover misuse, damage or general wear and tear.
The tank itself should last quite some time (usually many months). The heating element inside (the atomizer or coil head) will need to be replaced regularly (1 to 2 weeks on average). Both the tank and the coil heads are covered for faulty on arrival only (DOA). Take great care not to lose the seals on the tank or it will cause it to leak.
Please be aware that plastic/polycarbonate tanks are not recommended for use with abrasive e-liquids or particularly acidic e-liquids such as some fruit flavours. Some ingredients in e-liquid can cause cracking, frosting or even melting of plastic tanks. Abrasive and acidic flavours and flavourings include, but are not limited to, absinthe, cinnamon, spearmint, citrus fruit, cola etc. Please bear this in mind if you're using an e-cig with any type of plastic tank. Glass and metal tanks are impervious to these ingredients and are suitable for all e-liquids.
There is no warranty applicable but manufacturing faults are covered.
