When handling leaking or damaged batteries / rechargeable batteries, always use suitable protective gloves to
avoid burning your skin.
Liquids leaking from batteries / rechargeable batteries are chemically highly aggressive. Objects or surfaces
coming into contact with these liquids could be severely damaged. Therefore, keep batteries / rechargeable
batteries in a suitable location.

9.2 Additional information about lithium rechargeable batteries
Modernlithiumrechargeable batteries aremuchmore powerfulandsignicantlylighter thanNiMHrechargeable
batteries. This makes lithium rechargeable batteries (especially lithium polymer batteries) particularly suitable for use
in model making.
However, lithium rechargeable batteries require particular care to ensure safe charging/discharging, operation and
handling.
The following section provides an overview of the potential hazards associated with lithium rechargeable batteries and

Ensure that the rechargeable battery does not overheat during use, recharging, discharging, transport or storage.

Use special carry bags to carry LiPo rechargeable batteries, which can lessen the consequences of a sudden
reorexplosion.
If there are any signs of damage or the outer casing starts to swell or bloat, discontinue use immediately.
