10. Battery Requirements
It is very important to follow these guidelines to avoid serious injuries. Bad handling of batteries
may cause them to leak, potentially rapidly, creating a risk of injury as the internals of batteries
are very corrosive. It is recommended to use Alkaline batteries in most use cases and Lithium
(LiFeS2) for cold use cases.
• Note the polarity of the batteries when inserting them. Polarity is always shown in the
battery compartment as well as on the battery itself. The plus side is marked on the
picture below.
• Note the voltage of the batteries. There are several voltages available for the same size of
batteries. See the product manual for details on which battery to use.
• Never mix type of batteries. Only use the same type of chemical compound in all
batteries.
• Never mix old and new batteries. Make sure all batteries used are from the same
package.
• Do not use old batteries. Batteries older than 2 years should be avoided as they may have
aged differently and therefore have different voltages.
• If batteries get warm within 5 seconds after insertion, remove the batteries immediately.
• It is recommended to use protective glasses when working with batteries.
Note polarity symbols in the battery compartment
