!	Warning
	Hazardous to persons and property, risk of pollutant emission.

A lithium battery can explode if treated incorrectly; improper disposal of old lithium batteries can result in pollutant emission. The following instructions should therefore be observed without fail:

•Do not throw new or discharged batteries into a fire and do not solder onto the cell body (max. temperature 100° C). Do not recharge, there is a risk of explosion. Do not open the battery, and only replace it with one of the same type. Obtain the replacement via Siemens (see the Reference Manual, Module specifications appendix C for the order number). This will ensure that you have a short-circuit protected type.

•Old batteries should be disposed of with battery manufacturers/recyclers if possible, or as hazardous waste.
