3.7v Efest IMR 2000mAh 18650 Battery - Button Top
For use with the XL3, the Silver Lava or any mod that takes an 18650 battery.
Safe chemistry LiMN 3.7V rechargeable battery is now available in 18650 size. Can be charge with any LiIon battery charger with 4.2V output.
Nominal Voltage : 3.7V
Capacity : 2000mAH
Lowest Discharge Voltage : 2.50V
Standard Charge : CC/CV ( Optimal charging rate 1.5A max. charging rate 4.5A )
Cycle Life : > 500 cycles
Max. continuous discharge rate : 10C
Max 10AMP (please note: This is Efests number, so do not go above this limit in your devices)
- Do not over-discharge/overcharge
- Recharge empty batteries ( resting voltage ~3.6V ) as soon as possible. Leaving LiIon batteries in discharged state will incur irreversible damage ( capacity / cycle loss )
- Do not short circuit ( will release tremendous current )
- Do not dispose of in fire.
This item cannot be sent to International destinations
Attention : These IMR cells have much lower internal resistance than regular LiIon 3.7V cells and they may end up with a higher ending voltage when charged in certain chargers ( especially older version WF-139 charger ). Please check the voltage of them right out of the charger to see if they are above 4.20V when fully charged with your charger. Overcharging above 4.25V may shorten life/cycles. Above 4.50V may even pop them or making them leak. DO NOT use the charger if it seems to overcharge IMR cells.
This is a claimed max 10 amp battery, if you are using this in your mods, make sure the ohms of your device does not pull more than 10 amps.
You can use this calculator linked below (or any ohm/amp calculator) to see if your amps are too high which can ause damage to the battery or worse to your safety

i have tried other brands of this battery and they do not hold a charge like these do.in my opinion efest is the best.

How much can one really say about a battery? It charges and holds a charge a long time. that's all I can ask for. that, and I know Erics batteries are safe

Other sites have these for over a dollar cheaper. Not seeing a discount here for vapers.

They fit my Gripper and my Vamo. Order some from another site and they did not fit at all.
Thanks I love them.
