• Charger and rechargeable batteries heat up when charging. Leave enough distance between the charger and the
rechargeable battery, never place the rechargeable battery on the charger. Never cover the charger and the battery.
Do not expose the charger and rechargeable battery to any high/low temperatures or to direct solar radiation.
• Never leave batteries unattended while charging them.
• Regularly recharge the rechargeable batteries (about every 2 - 3 months). Otherwise, self-discharge of the batteries
may cause deep discharge. This renders the rechargeable batteries useless!
NiMH rechargeable materials (except for specific builds with low self-discharge) lose their energy even within a few
weeks.
LiPo batteries usually retain their energy for several months; however, they are damaged permanently by deep
discharge and cannot be used anymore.
• Never use a too-high charging current. Observe the manufacturer information on ideal or maximum charging currents.
• Remove the battery from the charger when it is fully charged.
• Charges and rechargeable batteries must not get damp or wet. There is a danger to life from electric shock; there
also is a danger of fire and explosion from the rechargeable battery!
Attention!
Rechargeable batteries with lithium technology (e.g. LiPo batteries) in particular are very susceptible to
moisture due to the chemicals they contain!
