Additional Information About Lithium Rechargeable Batteries - Conrad 2330830 Notice D'emploi

b) Additional information about lithium rechargeable batteries
Modern lithium rechargeable batteries have a significantly higher capacity than NiMH and NiCd
rechargeable batteries and are more lightweight. This makes lithium batteries (especially lithium
polymer batteries) particularly suitable for use in model making.
However, lithium rechargeable batteries require particular care to ensure safe charging/discharg-
ing, operation and handling.
The following section provides an overview of the potential hazards associated with lithium re-
chargeable batteries and explains how these hazards can be avoided to ensure a long lifespan.
• The casing of many lithium rechargeable batteries is made of a thick film, which is very sensitive. Do not
dismantle, damage, drop or insert any objects into lithium rechargeable batteries! Do not apply mechani-
cal loads or pull on the rechargeable battery's connection cables. This may cause a fire or explosion!
Pay attention to this when the rechargeable battery is attached to or removed from the model.
• Ensure that the rechargeable battery does not overheat during use, recharging, discharging, transport or
storage. Do not place the rechargeable battery next to sources of heat (e.g. a speed controller or motor)
or expose it to direct sunlight. Overheating of the rechargeable battery may cause a fire or explosion!
The temperature of the rechargeable battery must not exceed +60 °C. (If necessary follow additional
manufacturer specifications for the rechargeable battery!).
• Use special carry bags to carry LiPo rechargeable batteries, which can lessen the consequences of a
sudden fire or explosion.
• If there are any signs of damage or the outer casing starts to swell or bloat, discontinue use immediately.
Do not continue to charge it. This may cause a fire or explosion!
Exercise caution when handling the damaged rechargeable battery and use suitable protective gloves.
Dispose of the rechargeable battery in an environmentally friendly manner.
Never store damaged rechargeable batteries in an apartment or in a house/garage. Damaged or bloated
lithium rechargeable batteries can suddenly catch fire or explode.
A lithium rechargeable battery fire is difficult to extinguish and produces poisonous gases. There are
commercially available special extinguishing agents for dealing with LiPo fires (fire extinguishers,
extinguishing granules, etc.).
• Always use a compatible charger to charge lithium rechargeable batteries and ensure that the charging
method is correct. Do not use NiCd, NiMH or lead battery chargers, as these may cause a fire or explo-
sion! Always select the correct charging method for your rechargeable battery.
• Always use a so-called balancer when charging a lithium rechargeable battery with more than one cell
(the charger comes with a built-in balancer).
• The charge rate for LiPo rechargeable batteries must not exceed 1C (or the value stated in the battery
instructions). This means that the charging current must not exceed the rechargeable battery capacity
(e.g. battery capacity = 1000 mAh, max. charging current = 1000 mA = 1 A).
