Scope Battery?

[tony3d]

Hi guys, I just got my new Owon SDS-7102 Scope today. Haven't had anytime time to really play withe it, but I am charging the battery right now, and I was just wondering if it's ok to leave the battery in the scope permanently even when powering off the mains, or should I remove it?

If you're going to use the battery power only occasionally and you don't mind the inconvenience, you could store it in a cool place in a half-discharged state to slow down the aging process. That's way most of the laptops now come with software which offers you an option to charge the battery to ~80% only.

If I leave the battery in, it can't be over charged correct? I really don't want to have to take it out all the time. The screws are very inconvenient.

Correct. All properly designed equipment utilizing Li-Io/Po batteries could be powered from mains indefinitely without any damage to the battery.

<aside rant>
The same goes for mobile phones. It pisses the hell out of me when my Samsung Galaxy SIII beeps at me in the middle of the night and lights its LCD up to tell me it's done charging and to disconnect the charger this very instant. Because of some eco bullshit. It's just retarded and unfounded from both the engineering and "ecological" point of view. It just shows how little the software team knows about hardware and how poorly the both teams communicate, if anything.

I only get a notification to unplug the charger if i disconnect my phone from the charger. It doesn't make a sound though.

All indication of a decently charged battery is that the status led shows green.

Indeed.

So it's better than Samsung but still pretty much pointless. Given the high efficiency of today's switching mode chargers (i.e. they waste next to no power under no load), what a business of theirs is it whether you want to keep the charger in the mains socket or not?

Most of the time I charge it through the usb port of a nearby computer, so it doesn't really bother me.

Like you, I can not really see the point of this, but I thought it could be worth mentioning this.

Sideways rant;
I have a 2010 Sony LCD TV on which you can hear relay clicks from when turning it on, or if you have turned it off 20 minutes before you hear the click.
I think it's some sort of "really low-power mode", only allowing a mcu to sense the soft power-button on the side and decode the remote control signals.

Haven't actually bothered to measure the power consumption during these 3 stages.

My nokia just stops loading when the Phone is charged. I measured power consumption a while back, just out of curiosity. I do not remember the numbers but at first it drew more power and over time the power dropped. When it was charged the meter read zero watt. The charger get a bit warmer while charging but is cold as the Phone is charges.

If you want to be sure then measure the power or current to the scope. If it still draws current when powered down, you better pull the plug when you do not use it.
