This set of replacement parts includes the Davis fan and much enhanced set of NiMH batteries for the Davis Vantage Pro2 24 hour Fan Assisted Radiation Shield.
Original part no 7758B is suitable for fans that have stopped working or are running rough due to age and includes the set of replacement rechargeable batteries that keep the fan running during darkness. The batteries supplied exceed the specification of the Davis supplied ones and being NiMH do not suffer from the memory effect of the original NiCad original Davis battery.
As a bonus, they also come pre charged for immediate use.
