Regardless of any [legal] precedent for either battery manufacturers, device manufacturers, or retailers being responsible for making good when batteries leak and corrode a device, and regardless of companies policy to do so regardless of [legal] obligation, IMHO, I believe it is a generally known fact that alkaline batteries tend to leak and corrode devices when left in the device for long periods of time with little or no use. And as such I believe it is the user's responsibility to prevent damage to their devices by not storing alkaline batteries in devices, and if they choose to, check them on a regular basis and replace them as necessary.
That said, I've had C-cell batteries corrode in a Maglite and I should know better! :green:
