You are so correct. I just want through this - the tender on my trike was flashing red, the warranty on the unit is 10 years - and, I had the receipt. Contacted then and the said send it in.
Meanwhile, I connected my backup tender, and all worked well. Here is the response I got from them - this is why I asked the questions.
Good Afternoon Donald,
I have received the unit you sent in for warranty replacement. This unit has been exposed to extreme conditions which has caused the unit to fail. This is not covered under the manufactures warranty and cannot be replaced. I have included a picture of the damage. Please be advised, this unit is not rated for Weather Resistance or as Waterproof. It is for household use only.
