I live in the USA and I'm in the UK right now, using a local SIM. If you don't offer than capability, you've shrunk your market to only the people who don't travel (hint:not the ones who tend to buy the fanciest phones).

Yup. I will never be a customer for a phone that doesn't let me use the SIM of my own choosing.

Haven't you seen it? It's huge.

There are more jumpers are the Finnish end though.

Yup. Lead acids can be optimized for different types of load.

45.83W for a day is 45.8333.. Joules * seconds in a day. = 45.8333.. * 24 * 60 * 60 = 3,960,000 Joules.

You're off by a factor of 1000

>(It's a joke! Claim down.)

I claim up. It's higher.

Small ones are affected more than big ones. A classic case is motorcycles with an added aftermarket alarm/disabler. The trickle draw dramatically shortens the life of the battery. Car's were not affected so much, but with increasing draw, the batteries have to be increased in size not only for capacity as for robustness in the face of trickle current.

I can't be arsed to go googling for real data, but when I was designing cell tower backup systems (a former life before I got dragged into cryptography), the load/reliability data came with the batteries.

And a nice strong light in the ceiling of the garage to power the solar cells.

Lead Acid batteries hate trickle current.

Devices that use it (clock, alarm, remote opener etc) should have a secondary battery that is OK with trickle current and recharges using an occasional a burst from the main battery. This would cost a few extra cents, so instead they just do it stupid way on most cars.

Yes. Well predicated.

>*should* fail-safe to the open position.

Not in my first MX5. It failed down.

My second MX5 and my first 350Z both solved this problem by not having retractable lights.

My coffee milk frother does this. It's not that unique.
 

For 45W? That's a lot of watts for a 15mA receiver.

No, that 1100w per day. That would be an increasing rate of power draw.

1100Wh per day. So a draw of 1100/24 W = 45.83W.

The 12V battery of a family member's Honda Civic didn't just draw more current than intended. It failed completely! The car could not start! The whole battery had to be replaced at cost to the owner and the Honda CEO was nowhere to be seen.
