Cells - the heart of your battery

Every battery that powers electrical equipment consists of interconnected cells with a specific lifespan. At Battery Empire, you can find various types of batteries, including 18650 cells. Check out our wide range of high-quality replacement cells and prolong the lifespan of your devices.

You should consider buying our cells we offer, even if your currently used batteries work fine. Perhaps you are a keen modeller, and RC cars are your hobby? Or maybe you're a photographer travelling through the countryside, always on the hunt for that one perfect landscape? Whatever your goal, we understand your needs. 

If you have just one set of cells, you're tethered to a constant source of power to recharge your batteries. Therefore, if you pursue an active hobby, it is worth having a spare battery pack that will not let you down at the crucial moment. That is the type of cells we offer. 

The battery marked with the number 18650 may be a little confusing at first. What is this number connected with, and does it matter when choosing a new cell? What should you know before buying cells? Check our tips!

What does the number on the cell mean?

The 18650 number is nothing more than the dimensions of a specific battery. They are responsible for indicating the diameter and length. That is, in this case, 18 millimetres is the diameter of the cell, while 65 is its length. Some cells have a slight variation in their dimensions, but despite these differences, the battery labelled 18650 should fit the device. 

We offer Li-Ion cells of various capacities and from many reputable brands, including Panasonic and Sony. The batteries are brand new, and make an ideal replacement for cells in torches, laptop batteries and many other devices. Our batteries offer a lifespan of up to 1000 charge cycles. Whereby one cycle is a full discharge and then a recharge of the battery. A cycle does not count if you charge the battery from, for example, half capacity to full charge.

Our products include cells without the memory effect. That is, the battery lifespan reduced by the value from which you started charging periodically. That means that even if you do not use a Li-Ion battery to its full capacity and start charging at 30%, the battery will retain its original lifespan.

The cells also have limited self-discharge, so they perform as charged themselves as charged, a ready source of energy for an emergency. Under the right conditions, at temperatures between 20°C and 25°C, batteries can await use for up to a year.

Don't invest in half measures

When the cells in your device can no longer keep up with your needs, you have two options. You can either replace the whole battery, or you can easily cut down on the costs associated with such a purchase. At this point, you might want to check out our batteries. 

We do not offer cheap replacements from unknown brands, as we believe that if your device still works, and the only problem is the durability of the battery it is worth replacing it with something of high quality. This way you can be sure that your equipment will last as long as it did when using original cells. When it comes to cheap batteries from an unknown source,  the price and high declared capacity can, of course, be tempting. Although it is worth mentioning, that often overstated capacity is just a dishonest marketing trick. It often turns out that these cells offer a much lower operating time than stated. What's more, suspiciously cheap batteries can be very dangerous. Their use may risk burning or destroying your device.

The materials used for the construction of the cells, through their robustness and safety, guarantee a long period of intensive use. Thus, you choose a battery that will support your device for up to three more years.

Our batteries feature a high discharge current - for example, Sony or Sanyo cells up to 20A. That means the battery delivers 20 amps non-stop. By choosing our replacements, you can be sure of full compatibility with your original equipment. So, you no longer need to buy an extra charger. Meaning you can be sure you will not pay more than the cost of buying batteries.

What should you pay attention to when buying 18650 cells?

First of all, pay attention to the number next to the symbol mAh meaning the milliampere-hours. The more mAh, the longer your battery will last on a single charge. You will also find high-current batteries in the category of cells; these are best suited to, for example, power tools. If you are looking for batteries with the same capacity, simply check how many mAh the original batteries you used had. 

Our shop offers, for example, smaller cells from Samsung with a capacity of 1500 mAh. We also offer high-capacity ones such as Panasonic cells, with up to 2900 mAh.

How to care for batteries?

Despite the many safeguards that Li-Ion batteries have, it is worth knowing how to maintain them. First of all, it is better not to let them discharge completely, and in the case of extensive storage, it is worth leaving the battery half charged. 

Cells should also be stored in a dry and dark place at room temperature. Remember, to only use branded and trusted chargers. Using substitutes of low quality may lead to the destruction of the cell.

By choosing batteries from our shop, you can be sure that even if there are any problems with the purchased equipment, we will help you in solving them. Therefore, when you buy cells, you also receive a one year guarantee, ensuring you a smooth exchange in the event of defects in the products. 

If you are looking for durable replacement cells that will not let you down, check out our wide range. In case you have any doubts about choosing the suitable batteries, please contact us. We will help you find the appropriate cells with the correct power and voltage. Get a solid and safe supply of energy for your device right now!
