Never completely discharge li-ion battery ( below 2.5V under load ).
Charge fully to 4.2V before first use.
Use charger specifically made for Li-ion batteries only.
Do not charge unattended.
Never attach any metal moving part |magnet| to the top-positive, or the bottom-negative battery contact.
Never use force to install (insert) li-ion battery.
Do not use old and new batteries together.
Use only high quality battery charger.
Do not expose to heat.
Do not short (connect) positive (top), and negative (bottom) battery terminals (contacts).
Keep battery that is not in use in plastic holder (or any insulating [plastic] container).
Do not charge battery over 4.27V (another reason to use high quality battery charger).
Do not store your li-ion batteries fully charged (for extended period of time -1 month and longer).
Store in cold and dry place at approximately 3.7V (storage charge).
After battery is discharged-don’t leave it discharged=>charge it as soon as possible
Recommended Charge Constant Current: 1.5A 1500mA
Lg HG2 can be charged with lower charging current | charging process will take longer.
Maximum Charging Constant Current: 4A | 4000mA
Max. Charging Constant Voltage: 4.2V
End of charge current cutoff: 100mA
