Which 18650 to buy

You can't simply buy a battery off the shelf by looking at the capacity measured in milliamp hours or mAh alone. The right battery depends entirely on what you're using it for. The isn't a standardized cell. They're not all built equally, or with the same task in mind. The most important trait to consider when looking at batteries is the continuous discharge rating CDR , also known as amperage capacity. The CDR is the rate at which currentmeasured in amps A can be pulled from the battery without it overheating.

In order to find out which battery is right for you, you'll need to match the CDR of the battery with the power draw associated with your device. If you pick the wrong battery, the cells will get too hot. Heat will damage the battery, reducing its overall lifespan. Overheating may even cause the cells to explode, leak, or damage your device.

The higher the capacity, the lower the CDR. That means devices that draw less power can take advantage of higher-capacity cells. Hungrier devices will need to use lower-capacity cells in order to safely draw more current. Some bogus manufacturers claim ratings of 40A, or 35A at mAh or greater, but these are not trustworthy ratings. Battery technology evolves constantly, so expect this to change. When shopping for batteries, you will have a choice between protected and unprotected cells.

Protected cells, as the name might suggest, have a small electronic circuit integrated into the battery packaging. This is located one end of the battery, and is indistinguishable from the cell itself. This circuit protects the battery against dangers like excessive charging and discharging, short circuiting, and extreme temperatures. This is designed to protect the devices you use them in, and to prevent damage from explosion or leaking. Temperature — 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 battery, we recommend keeping it within a range of 3. This tip does take some effort as most batteries will discharge down to 2. 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 batteries, you should always make sure your charging device automatically turns off when charging is complete. It is also recommended to remove the batteries from the charger once charging is completed as many chargers have a function to continually top off the battery to make sure it is always at max capacity. This constant topping off can stress a battery and cause it to age prematurely. Charge Rate — There are chargers on the market capable of charging at 4A or even 6A.

While this can be very convenient, keep in mind rapid charging can accelerate the aging process as these speeds put added stress on the battery cell. A healthy range to charge your batteries at is anywhere between 0. These batteries are neither designed nor intended to be used with an e-cigarette, vaporizer or similar device. The current li-ion market is very scarce as supply struggles to keep up with the demand.
