• Please observe correct polarity (plus/+ and minus/-) when connecting the
rechargeable battery to your model or charger. Connecting the battery
incorrectly will not only damage the model but also the battery. There is a
risk of fire and explosion!
This charger has a mechanism that protects against connecting the poles
incorrectly. Nonetheless, it is possible that an incorrectly connected battery
may lead to damage in certain situations.
• If the product is not to be used for a long period of time (e.g. storage),
disconnect any connected battery from the charger and disconnect the
charger from the power supply.
• Do not charge/discharge any battery that is still hot (e.g. caused by high
discharge current from the model) Allow the battery to cool down to room
temperature before attempting to charge or discharge it.
• Never charge/discharge damaged, leaking or deformed batteries. This can
result in a fire or explosion! Dispose of any unusable rechargeable batteries
in an environmentally compatible fashion. Do not continue to use them.
• Never use battery packs that are composed of different types of cells.
• Recharge the rechargeable batteries about every 3 months, because other-
wise there may be a total discharge due to self-discharge, which makes the
rechargeable batteries useless.
• Remove the battery from the charger when it is fully charged.
• Never damage the exterior cover of a battery. There is a risk of fire and
explosion!
• Never charge/discharge a battery directly in the model. Remove the battery
from the model first.
• Place the charger and battery on a non-flammable, heat-resistant surface
(e.g. stone tiles). Maintain enough distance from flammable objects. Allow
enough distance between the charger and the battery - never place the
battery on the charger.
• As both the charger and the battery heat up during the charge/discharge
procedure, it is necessary to ensure sufficient ventilation. Never cover the
charger or the battery!
