So from begin to end:
We sold our boat, everything is paid etc, the buyer will come pick it up in 2 days, they have to sail a day to get to the destination.
We charged the batteries(like they asked) and one of them emitted a strong sulfur smell (like rotten eggs) which means this battery is dangerous and shouldnt be used.
My mom (old owner) told the buyer to change it some time, then on my advice sent a extra message that for safety its best to just remove this one asap.
Now my parents are mad "the battery still works" and "not our problem"
It does power lamps, but safety is important too. Fire protection too.
I told my parents i could change it real quick if they bring a extra battery (i am technical) but they shrug it off and dont care about safety apparently
UPDATE: my mom wanted to call with a technical story who proved me right. My mom is on my side now and wr dont listen to dad but he just said "oh" anyway.
Tommorow i will be removing the battery.
NTA. Buyers have a duty to disclose known issues with what they are selling, particularly safety issues. What happens to the buyer if this battery causes a fire while at sea? This is like selling a car without brakes when you know they are planning on driving it home and being mad at you for forcing them to tell the buyer that the brakes don’t work.
At very least, as a seller of an item we have a responsibility to make sure that the product we are selling doesn’t kill someone by keeping a known issue secret.
You’ve done your due diligence:
>My mom (old owner) told the buyer to change it some time, then on my advice **sent a extra message that for safety its best to just remove this one asap**.
NTA.
NTA. Your parents know the battery is bad, if they fail to disclose that the battery is bad and something happens then your parents can be sued.
They sold an item used/as is and informed the buyer of the issue with the battery. They are not required to replace the faulty battery. They have done the safe thing and made the new owner aware. The new owner can decide if they want to replace it.
YWBTA if you insist that they should change the battery.
NTA for insisting they are open with the buyer about the issue with the battery.
NTA. Good looking out. Thanks for having a conscience. We buyers who tend to be too optimistic and trusting certainly appreciate it.
NTA. Buyers have a duty to disclose issues. Otherwise, they can be sued. Good on you for changing the battery out.
