• Never charge batteries immediately after use. Always allow them to cool down for at least 5–10 minutes.
• Always remove the battery from the vehicle before charging it.
• Place the charger and battery on a heat-resistant, non-combustible surface.
• The charger and battery will heat up during the charging process. Ensure that there is a sufficient dis-
tance between the charger and battery. Never place the battery directly onto the charger. Never cover
the charger and the battery. Do not expose the charger or battery to extremely high/low temperatures
or direct sunlight.
• Never leave batteries unattended when they are charging.
• Rechargeable batteries should be charged regularly (approx. once every 2–3 months) to prevent deep
discharge due to self-discharge. This may result in permanent damage and render the batteries useless!
NiMH rechargeable batteries (except special batteries with a low self-discharge) lose their charge within
a few weeks.
LiPo batteries usually retain their charge for several months. However, deep discharge of the batteries
will result in permanent damage and render them useless.
• Never use an excessive charging current. Observe the manufacturer's specifications for the ideal/maxi-
mum charging current.
• Disconnect the battery from the charger when the battery is fully charged.
• The charger and the rechargeable battery must not get damp or wet. This may result in a fatal electric
shock or cause a fire or explosion!
Lithium rechargeable batteries (e.g. LiPo batteries) contain chemicals that are very sensitive to moisture!
