SKU: samsung30q

Genuine Samsung 30Q 3000 mAh batteries.  This is an amazing cell, extremely low internal resistance similar to the 25R but with a higher capacity of 3 Ah.  A great battery for 10-50W per battery devices.  As always, we've done extensive testing to be sure they're real so you can be confident you've got the real thing, grade A.  

Note that these can either be made in Samsung's South Korea or Malaysia plants.  These batteries are equivalent with the same part number and you may receive either one since they are commingled.  The Malaysian ones are listed as Samsung SDIEM whereas the Korean ones say Samsung SDI on them.

Battery Warning

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.

All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

Here are a few tips:

  • Never completely discharge batteries (below 2.5V under load or 3V unloaded)
  • Charge fully (to 4.2V) before first use
  • Never charge batteries to 4.3V or above
  • Do not charge unattended
  • Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)
  • If you must store your battery, only store in a case or individual box in a cool and dry place at approximately 3.6-3.7V
  • Use only high quality battery chargers
  • Do not expose to heat
  • Do not connect the positive contact to the negative contact without an appropriate load
  • Never exceed the battery's specifications
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
  • Always charge these batteries on and within fireproof material
  • Never leave rechargeable batteries in a recharging station unattended
  • Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
  • Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
  • Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
  • If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
  • If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

The best!

I LOVE Liion! I have been vaping for 6 years now and there is not one other place I go to for batteries. The prices can't be beat, especially for verified authentic batteries, and the shipping is amazing fast for USPS. I most appreciate the free battery cases that come with every order. Not only because yay free stuff, but also because it shows that the company cares about battery safety, not just making a quick buck. These batteries do everything they are described to do. They work all day with regular vaping at 70-80 watts and they provide enough power for my 3 different mods. I'll be ordering more VERY soon!
