Cautions

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
