High Rate 18650 Li-ion Battery

High Rate 18650 Li-ion Battery

High Rate 18650 Li-ion Battery Rechargeable Cylindrical Lithium-Ion Batteries with 30A discharge current, 3500mAh high capacity with 10A.

Highest Amperage 18650 Li-ion Battery Rechargeable Cylindrical Lithium-Ion Batteries with 30A discharge current, 3500mAh high capacity with 10A.
The CDR of 30A is the highest true rating among all lithium-ion 18650 batteries and it has tested to maintain a low running temperature at up to 40A CDR.

Continuous Discharge Rating (CDR) with High Rate 18650 Li-ion Battery

This is probably the most important thing to consider when selecting a High Rate 18650 Li-ion Battery. You need to know how much current the device you are trying to power requires before choosing your high Rate 18650 Li-ion Battery. If you choose a 18650 Li-ion Battery with a current rating less than what you need, you will notice the High Rate 18650 Li-ion Battery overheating as it is working beyond its ability to keep up. There are also two terms you should know that are discussed in the high Rate 18650 Li-ion Batterycurrent ratings. Those terms are continuous discharge rating (CDR) and the pulse discharge rating (Pulse).

CDR – High Rate 18650 Li-ion Battery

The maximum current at which the High Rate 18650 Li-ion Battery can be discharged continuously and safely per manufacturer testing without damaging the High Rate 18650 Li-ion Battery. Pushing a High Rate 18650 Li-ion Battery to limits beyond its ability will greatly increase the risk for High Rate 18650 Li-ion Battery failure.

Pulse Rating – High Rate 18650 Li-ion Battery

The maximum current at which the High Rate 18650 Li-ion Battery can be discharged for a short period of time without damaging the high Rate 18650 Li-ion Battery or reducing its capacity.

We avoid using any pulse ratings as there are far too many factors to consider when pulsing a high Rate 18650 Li-ion Battery such as a pulse length, time at rest between pulses, and high Rate 18650 Li-ion Battery temperature to accurately compare two High Rate 18650 Li-ion batteries. For these reasons, we use the CDR rating which is the current rating at which the High Rate 18650 Li-ion Battery can be continuously discharged safely without overheating or damaging the cell.

Voltage – High Rate 18650 Li-ion Battery

When someone refers to a battery “hitting harder”, what they are referring to is the voltage at which a High Rate 18650 Li-ion Battery can sustain midway through its cycle, commonly referred to as voltage sag. Some High Rate 18650 Li-ion Battery can remain around 3.7V midway through the cycle while other batteries will drop to 3.2V or lower when drawing power causing a sag in power.

Operating Temperature – If your High Rate 18650 Li-ion Battery is consistently reaching a high temperature and getting hot, this is a warning sign that the 18650 Li-ion Battery is being pushed too hard. A High Rate 18650 Li-ion Battery that is consistently rising above 45C will certainly age faster than a cool running battery. They can also be dangerous as the potential for venting and/or bursting is increased greatly with a high-temperature lithium-ion battery. You should consider choosing a High Rate 18650 Li-ion Battery with a higher CDR rating.

Flat top and Button Top – High Rate 18650 Li-ion Battery

One final thing you want to consider is whether you need a flat top High Rate 18650 Li-ion Battery or a button top High Rate 18650 Li-ion Battery. This is referring to the positive end of the battery. A button top High Rate 18650 Li-ion Battery has a protruding surface that increases the battery’s length and may not fit in a device that requires a flat top battery. A flat top is as the name suggests a flat surface and may appear to be too short if your device is requiring a button top battery.

Caring for your 18650 Battery – High Rate 18650 Li-ion Battery

There are many safety precautions that should always be taken when using, handling, and/or storing lithium-ion batteries. Please refer to our battery safety guide for these tips. The following tips are suggested to get the most life out of your 18650 lithium-ion batteries.

Temperature – 18650 Lithium-ion batteries will age at an accelerated rate below 0C or above 45C. If you are running your batteries hot, this will certainly cause premature aging.

Discharging and Charging – To get the max life from your High Rate 18650 Li-ion Battery, we recommend keeping it within a range of 3.0V – 4.0V. This trip does take some effort as most 18650 Lithium-ion batteries will discharge down to 2.5V before requiring a recharge and will fully charge up to 4.2V. The logic behind this is when you push the cell to the extremes of its capabilities; it puts stress on the battery. In testing, batteries kept in this range will have double the life expectancy.

Charger – To get the most out of your 18650 Lithium-ion batteries, you should always make sure your charging device automatically turns off when charging is complete. It is also recommended to remove the High Rate 18650 Li-ion Battery from the charger once charging is completed as many chargers have a function to continually top off the High Rate 18650 Li-ion Battery to make sure it is always at max capacity. This constant topping off can stress the High Rate 18650 Li-ion Battery.
