My Raymarine 101 is almost new and never been used in anger. The Ni-MH/Alkaline switch inside the battery compartment has fallen apart and there are signs of corrosion around it. The problem came to light when the VHF wouldn't accept a charge. This was the first charge after the initial charge when it was first received from the retailer. The radio has hardly been switched on let alone used and has never been damp or wet, although this should not be an issue as it is marked on the cover as being waterproof. Overall, I'm not impressed and hope that there will not be a problem having the battery pack replaced under guarantee. I have no confidence that the problem would not happen again as the switch in question does not look very robust and is probably vulnerable to ingress of damp. CJ
