19650 Ratings & Specifications
Just like any other battery, the 18650 is composed of three main components. It has two terminals famously known as the anode and cathode which have been made of different metals, and the electrolyte that separates the two terminals. Basically, the anode is negative while the cathode is positive. The electrolyte, being a chemical medium allows the electrical charge to flow between the cathode and anode. The battery has a separator in the cathode and the outermost part is referred to as battery wrap.
Continuous Discharge Rating (CDR)
Have you ever heard of the continuous discharge rating (CDR)? Well, this is the rating that’s not only used to compare battery discharge but also used by reputable electronic manufacturers. When rated, it depicts the current you can safely discharge the battery at a continuous rate without necessarily reducing its capacity to function efficiently or being damaged.
Many are the times when Chinese manufactured batteries or other rewraps overstate the CDR or use other ratings. A very noble example is the maximum discharge current, also known as maximum discharge rating which might be the only rating you find on the wrap and is the maximum current supplied by a battery in short intervals. When shopping for a battery, you should not take into consideration this rating because it could be misleading and you’ll end up buying something you never planned for. If you want to give value for your hard-earned money, take your time and examine the CDR of a battery and check ratings online and you’ll surely get the battery worth your money and effort.
The capacity of a battery is calculated in milliampere-hours usually abbreviated as mAh and signifies the running time of a battery. Basically, one mAh is equivalent to the charge a steady current of 1 mAh can transfer when flowing for an hour. Due to the increase of counterfeit products all over the world, you won’t be surprised to realize that mAh is often overstated on battery wraps, although not as common as the overstated discharge ratings.
If you want to buy the right battery for your mod, take consideration and pattern of a reputable battery manufacturer and you’ll realize a close relationship between CDR and capacity. For instance, you can never find a 18650 with a CDR more than 30 amps and similarly, you can’t find 18650 with a capacity of more than 3000 mAh with a CDR of more than 20 amps. As a rule of thumb, therefore, don’t buy any battery that’s not rated as per the two rules because there are high chances that it will be falsely rated and not worth your money.
It goes without saying that looks can be deceiving and because you work so hard to earn money, always consider buying batteries you can rely on. For instance, stay away from rewraps simply because the batteries used on them can change with time. As stated earlier, 18650 batteries are readily available and you should take quality time to ensure that what you buy is from a reputable manufacturer, and that’s the only way you’ll find happiness in buying what you plan for.
