LG MJ1 INR 18650 3500mAh 3.7V Unprotected High-Drain 10A Lithium Ion (Li-ion) Flat Top


Out of stock

These LG MJ1 INR 18650 batteries can provide reasonably high-drain devices at 10A continuous drain rate while giving a respectable 3500mAh capacity for a long-run period.

The LG MJ1 INR 18650 batteries emphasize a flat top terminal and are unprotected so that users can use them to gather their battery packs, such as within producing tools.

These 18650 rechargeable cells emphasize a hybrid li-ion manganese nickel chemistry that blends the stability of manganese with the powerful energy of nickel.

This is why the LG MJ1 green-wrapper battery can produce such a high capacity while enduring stability and reliability, even during high discharge projects. These LG MJ1 18650 batteries give the same power as the Sanyo GA but with a significantly higher lifespan.

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. 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
