1 - I recently purchased a MYO-series headlamp. How can I find out if it is compatible with AA/LR6 rechargeable batteries?
Due to advances in the performance characteristics of AA/LR6 rechargeable batteries (especially their higher output during discharge), they can in certain cases of intensive use, cause quality and safety problems with MYO-series headlamps. When the headlamp is used with AA/LR6 rechargeable batteries, if a short-circuit appears in the cable connecting the battery case to the lamp, the cable can spark, melt, or catch fire. This poses a burn hazard tothe user.
The number of reported incidents is very low, representing 0.004% of total MYO headlamps sold. Nevertheless, this rate of incidence does not meet our standards ofreliability and safety.
As a result, Petzl has decided to alert endusers and to take the necessary correctiveactions.
This information applies to all Petzl MYOseries headlamps manufactured before the end of June 2008. For these headlamps, only alkaline batteries should be used. Rechargeable AA/LR6 batteries must not be used. (photos, MYOLITE, MYO)
Since July 2008, modifications are underway for our currently available MYO headlamps to make them compatible with AA/LR6 rechargeable batteries.
