Is that really much of an issue? I've never noticed any condensation forming on them. And I guess you could avoid that problem by putting them in airtight bags.

No, because the humidity is outside the fridge...... When I mentioned condensation on a beer glass, does the beer has condensation on it in the fridge? no.
Condensation is caused by warm/moist air coming into contact with a cold surface.

As for batteries in fridges, just look at this https://www.youtube.com/watch?v=PRYYMXH7DUQ

Oh yeah -- fair enough. :-)

As I said above, you should use batteries at room temperature. The (completely unscientific video) agrees with that.

I've seen arguments about this countless times.

As the OP uses her machine in a fixed location and probably always will then just how degraded the battery may become is pretty immaterial so I'd recommend doing whatever is most convenient.

I have a fixed place laptop and just leave the charger in 24x7. I've always done that with my laptops over the years and never had a battery fail on the odd occasion I've actually used one off the mains.

For my phone and tablet I just charge them up each evening regardless and also top up during the day if I plan on a streaming session later.

My laptops, phones, and tablets have become obsolete before I've encountered battery problems.

My wife's Lenovo and her old HP Pavilion, both carried information in the Guide, to the effect that the battery required to be calibrated. This involved charging the laptop to Full Charge from new, the using it without the charger plugged in, until it gave a warning about Low Battery. Repeating this procedure a number of times (can't recall how many) was meant to calibrate the battery to accept this as normal and setup the Low charge point.

I am afraid I cannot afford to change a device before it becomes "obsolete". It has to serve until it actually becomes unusable and/or wears out.

I just got a new Li-Ion Battery Pack the other day so the following comes straight from the instructions that came with it.

Calibration as mentioned above. At intial use, fully charge and discharge 3 or 4 times. One cycle again every two or three months.

Storage. Between 60% and 80% charged in a cool, dry and clean place. Do a full charge and discharge every month.

Repeated charging. Life is only measured by complete charging cycles and partial charges don't matter and are not harmful, although they should all be added together to give overall "age".

Others. The circuitry means they only charge when they fall below 95%, so it does no harm to have the power connected with a full battery. You're not degrading it by overcharging because it isn't happening.

Still using the old Nokia then? I still have one that isn't broken it's on the original battery too and last time I checked it still powered up. It used to be an emergency phone left in the car until the £1 a month sim it was on got put up to £5.

Ive got a lot of practical experience with LiPo batteries as a result of flying electric RC planes for a hobby. Performance is everything here and I do keep a careful eye on capacity and internal resistance in order to calculate flight times and maximum power output.

What I can say with absolute certainty is keeping LiPo cells at or near full charge for long periods will ruin them very quickly.

I was interested in this thread as I've got an HP Envy too. But you can't take out the battery or I've not found a way to get inside yet.

IMO that's pretty poor for laptops at that price level. I have an HP stream which is really a big tablet with a keyboard and was cheap so I take the possibly non-replaceable battery as par for the course and in any event for me it's a non issue as I don't tote it around with me and just use it plugged in like a desktop (which I also have).

I use my laptop off the mains all the time but with the battery taken out. This way, it doesn't lose any charge capacity from being overcharged. If i ever need to move the laptop about and mains is impractical then i slot in the battery.
