Yes, especially wearables and toys. Those are a real problem. One of my kids was gifted a toy that had an embedded Lithium Ion pouch battery of spectacularly bad quality, the pouch had already inflated to the point that it was unsafe to dispose of when he got it. I ended up hand delivering the whole thing to the local disposal site where they have the proper gear to deal with these.
It does help. It raise the opportunity to discuss it, which is helpful because not everyone is aware that this is a problem, and like many other lease clauses it is there to assign blame in case an exceptionally bad event comes to pass.
Interesting, and ominous. If the place burns down and they find the remains of a "TrustFire" battery in the debris, they might try to refuse coverage, leaving you with the task of recovering damages from the tenant. And good luck with that...
Nah, tenants will sign just to move in, and forget about this clause. Just like any tenant that smokes weed disregards no drug clauses. Tenants are going to do what tenants do. Unless you're doing routine walk throughs looking at every single thing in the place that could use a battery, then you'll never know. It's a useless "regulation", and we have plenty of those in the world already.
And the "intelligent" part makes them realize that you get absolutely nowhere if you try to strictly follow all rules (there's a reason why "work to rule" is an effective sabotage strategy), and that the path of least resistance is to sign and ignore it.
It’s not unjustified. I’m a tenant. I don’t read all of the clauses. I’m a normal well meaning intelligent person. Does not change anything about what I said.
