Never charge batteries unattended.
Put battery in the fireproof container and charge in an isolated area, away from other flammable materials. Always have fire extinguisher for emergency use.
Let battery cool down to ambient temperature before charging.
Do not charge batteries packs in series. Charge each battery pack individually. Failure to do so may result in incorrect battery recognition and charging functions. Overcharging may occur and fire may be the result.
When selecting the cell count or voltage for charging purposes, select the cell count and voltage as it appears on the battery label. As a safety precaution, please confirm the information printed on the battery is correct.
a. Example: The label on a 2-Cell battery pack in series will read charge as 2-Cell (7.4V), or may cause fire. You must select 2-Cell for charging.
b. Example: The label on a 3-Cell battery pack in series will read charge as 3-Cell (11.1V), or may cause fire. You must select 3-Cell for charging.
Selecting a cell count other than the one printed on the battery (always confirm label is correct), can cause fire.
You must select the charge rate current that does not exceed the battery's allowed charging current. (Please double check the battery's specification)
