The real issue is our building regulations are an absolute joke. It should be mandatory to include ducting to each room and then at least include a balanced pressure ventilation system. That alone massively reduces errant humidity from sources like cooking / showering etc (no, an asthmatic range hood or pathetic fan wired to the light switch is NOT sufficient).
I live in a crappy 80s house with single glazing and poor insulation. I’ve got to run 3 dehumidifiers 24/7 at 60% here or else it’s mould city. In winter it’s massively helpful if I heat the place - have heat pumps in every room just about and as the house is pretty open plan I run them on a timer to maintain a minimum of 21 in the living areas during the day and 18ish when sleeping. In summer I cool as well which removes the humidity from the air.
But you’re right, NZ, and specifically Auckland is hella humid as it’s a thin piece of land in the oceans. I’ll be moving to central NI soon, bit further from the coast. The weather seems way more stable compared to living so close to the coast, and the slightly more sane property market doesn’t hurt either.
That is correct. LiIon batteries don’t outgas when charging. Outgassing often means a catastrophic failure is imminent.
“Charging for too long” is not a thing for any kind of lithium ion battery.
A lithium ion battery requires something called a BMS (a battery management system) which is responsible for ensuring the battery doesn’t get too hot when charging or discharging. Good quality Batteries often include multiple temperature sensors and fuses inside their BMSes so power is cut or charging halted if abnormal condition are detected.
Unfortunately, due to the popularity of these devices from escooters to e-cigarettes that use LiIon batteries, it is inevitable that some unscrupulous individuals attempt to cut corners to bring “cheaper” batteries to market that often do not contain these safety mechanisms, or less robust versions of them.
Long story short don’t buy no-name branded shit that has LiIon batteries, and don’t worry about charging it. Once it’s full, it stops automatically. Remember phones have had lithium ion batteries for much more than a decade and they very rarely if ever go bad (Barring the Samsung galaxy event). So don’t write off the tech just because some potentially dodgy battery went bad and caused a stuff article.
Additionally, I think it’s worth learning about LiIon chemistry in general and understanding what is harmful to it: high temperatures; charging under low temperatures; leaving them very full or very low for long periods of time. But really, if one purchases a good quality device, it comes with a management system that manages all these things for you. Unfortunately most people go for the cheapest option.
