Currently we use alkaline batteries which have a life of approximately 3-6 months or 12 months, depending on your Fiobuoy model and usage patterns. We prefer to use alkaline batteries because they are compatible with the Fiobuoy’s specific electrical requirements. We are however constantly reviewing other battery chemistries and expect to be able to use some of the newer lithium technologies soon.
Our 200m models do have spare internal space to support two battery packs providing extra energy for longer deployments.
