Limitations on use of AA/LR6 and AAA/LR03 Lithium batteries with
headlamps.
This information does not apply to the Petzl e+Lite which was
designed to work with CR2032 Lithium batteries.
Lithium batteries are lighter and give longer burn times at low temperature
than traditional alkaline batteries.
Recent advances in the performance
characteristics of Lithium batteries (especially their higher output during
discharge), mean they can cause the lamp to overheat and possibly damage the
LEDs.
Therefore we recommend you do not use lithium batteries in any torch that
uses LEDs unless the manual specifically advises to (eg Petzl e+lite or Petzl
Signal).
Lithium batteries can be used with incandescent bulbs but will
reduce their lifespan.
