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. 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

LG HE2 18650 20A (***) Flat Top 2500mAh Battery

Although I have not purchased this item from this company, it is one of the main batteries I trust for vaping with a mechanical (tube) mod. 2500mah means long life in a regulated mod (has a screen and +/- buttons to adjust wattage or voltage) It is one of the top batteries used by vapers. See review Battery Mooch. You will notice I *** out the "pulse rating" and suggest this vendor remove it from the description. Pulse rating is a non value. There is no way to know what standards the manufacturer or vendor used to determine this. I know in fact, that I have pulsed this cell at over 50A. Keep in mind please, I am an expert vaper so do not try this if you are a beginner or novice. My "pulse" was under 3 seconds with 30 second rest period between. The main thing to know, is under no circumstance should you continue using this battery when it becomes hot, maximum 100F. Anything higher you run the risk of venting so stay below 100F. Recommended resistance for this cell in a mechanical mod is 0.18 to 0.22 ohms. (consider this to be 'relatively pretty safe') It is your responsibility to make sure the cells aren't damaged, including the wrapper. NOTE.. one user gave this cell a 1 star rating. From his post I can say he was using a damaged cell. Most likely using a cell with a damaged wrapper. (as per hissing and popping... a sure indication of arcing and venting due to a short) Remember.. electricity follows the shortest path. If that is from a hole in the wrapper to the wall of the flashlight.

Both ordered batteries have been delivered undamaged owing to good packaging. After full charging they showed very close voltage.

I bought these for my wife's Vape. These seem to hold a charge well and last for several hours. For the price they are a good buy.
