Use AA Lithium batteries instead of C batteries in your C-1003 SOS eVDSD
Works with the Sirius Signal C-1003 only – not intended for any other SOS eVDSD
Increase your battery shelf life: Lithium batteries are considerably less prone to leakage compared to their alkaline counterparts
Double your power options: Adapter is removable so your SOS eVDSD can run with either C-cell or AA cell size battery type
Keeps your SOS distress signal working: Run your C-1003 on (3) AA Lithium Batteries instead of (3) C-Cell Alkaline batteries while maintaining peak performance
