Troubleshooting your Li-Ion Battery

Battery

Notes

510, 901,808 and other China batteries

2.5 ohm is the standard but they will work as low as 2.0 ohms.  Higher resistance produces less vapor.

Below 2.0 ohms, the battery life is signifigantly reduced and the batteries may be damaged

Not Recommended

eGo

2.0 - 2.5 ohms.  Same as above

Same as above.

1.5-1.7 ohms

3.7 Volt mods, roughstacks, box mods, e-Power

1.7 to 3.2 ohms

Above 3.2 ohms, vapor production will be reduced. Lower than 1.7 ohms, battery may think it's a short and not work.

1.5-1.7 ohms

5 Volt mods

2.5 to 3.2 ohms

2.5 ohms may cause some juices to burn. Lower resistances may not work and will tend to burn liquid or blow out the atty or carto.

2 ohms

6 Volt

3.2 ohms and up

Lower ohms will tend to burn out the atty or carto or burn the liquid.

2.5 ohms

7 Volt

4.5 to 5 ohms

Personal preference on most of these but lower than 4 ohm tends to burn e-liquid and the actual cartos or atties will burn out quicker.

1. Is this a brand new battery you have never used or is it one you already owned?
   1. New Battery – Be sure to fully charge the battery first.  Not all batteries are charged when you receive them.  It can take up to 6 hours to fully charge a Li-Ion battery.  Be sure that this battery or batteries, if you are using more than one in series to create higher than 3.7 volts, is compatible for the mod you are using it for and that the resistance of the atomizer or cartomizer you are using is appropriate for your voltage.  (See the chart below.)
   2. Used battery – Again make sure it is fully charged.  Did the battery ever work for you?  If you are using it in a new mod, test it in the old one.  If you are using it in the same mod with a new cartomizer make sure you are using a recommended resistance. (See the chart below).  Is the battery damaged physically?  Have you dropped it?  The protection circuit of the battery has a circuit board, if you drop the battery it is possible to break the solder points on the circuit board which can make the battery fail.  Do not try to repair a bad battery, this is very dangerous.

2. Does the battery work for a second and then stop?
   1. If this is the case you may be using a cartomizer or atomizer that has too low of a resistance.  This can trip the protection circuit of your battery.  To reset the protection circuit, remove the battery or batteries from the mod, place it/them in the charger.  This will reset the protection circuit on most batteries. Most mods that use a voltage regulator also have protection for over current and overheating. The protection on the regulator chip can also be turned on by an atomizer or cartomizer that is too low in resistance and is drawing more current than the device will support. This problem is usually identified by the ability to turn the device off (or remove the batteries), then turn the device on (or re-install the batteries) and it works again.

3. Have you tried adjusting the center pin on the connector?
   1. A lot of times a battery or a mod will appear to be bad but it could be that there is not a good connection to the atomizer connector. The center pin in the connector can become compressed over time.  This could be from screwing the atomizer or cartomizer in too tight or because some manufacturers center pins on their atomizers or cartomizers are slightly different.  To adjust the center pin on your connector, use a small screw driver or paper clip and gently circle the center pin prying it up just a little bit.  Then reconnect your atomizer or cartomizer and see if it works.  Remember you do not want to tighten a cartomizer or atomizer down too much, just until there is contact.  To see a video of how to adjust the center pin click here.

4. How old is your battery?
   1. Li-ion batteries have a good lifespan, but they do not last forever.  If you have had the battery for over 6 months, it may have just failed due to age.  Li-ion batteries will over time retain a memory.  When this occurs the battery will need to be recharged more often and may not charge as fully.  Eventually the battery will need replacing.

5. Use a Quick Li-Ion Battery Tester.
   1. If you dont have a volt meter, you can use our new Quick Li-Ion Battery Tester.  It is only $0.39.  You can't beat that!  Simply touch the free end of the resistor to the positive end of the battery and the negative end of the LED to the negative end of the battery. If the LED turns on, then the battery is probably okay and it would be time to look at the mod or other factors in determining the cause of failure.
