What is the amperage draw on this unit when on and when in standby? Just curious for length before battery is fully drained.

I leave mine on all the time and it draws less amperage than an alarm-no moving parts whatsoever. You can set it to shut down after the vehicle is stopped too. I bought another one for my other car too.

I think that I read somewhere that the time which it has on "stand alone" internal battery was about 50 minutes, although I am not sure about that ... I can't find it right now. As far as amperage draw is concerned, I don't have a clue.

how big is the batteryhow long has it been discharged and are any of the cells shorted24hrs is not unusualthis is a low amp charger and it takes a long time to charge anything

Sorry, I can't answer that one. I have only used this at home so it's plugged in. I haven't taken it out for anything on-the-go to see how the battery power lasts.

Ansgar - I am sorry but I don't really know. When it arrived it was nearly fully charged. Since then I have usually just plugged it in every once in a while. I'll try to really run it down and they take note and try to pass the info on. Sorry I could not have been of more help.----M

It would completely depend on what you are running I have not ran it down yet but you never really want to run a battery with high amp draw down under 40% with. I would guess a dc refg 3 days. You take the total amp hours times 12 gives you the watt hours on the battery. I haven't done it yet.

I watched a couple Youtube video reviews where people used meters to check and it seems there is between 11 and 16 watts in over head while the battery is charging. If the unit is turned off and still plugged into the wall outlet the battery will still charge to keep it at 100% but not actually output power to it's outlets. If the battery is 100% charged then there is no draw what so ever.The only way to know for sure what is going on is for you to actually test your unit to see how much power it is consuming. From what I saw in the video's on Youtube it ranged between 0 and 19 watts, depending on the charge state of the batteries.

It depends on the draw. If it's a computer at rest or hibernating, you might get 30 min. Less power draw, more time.You can set it to shut down the computer at a percentage of remaining battery power. I have mine set to 20% remaining. You have to download software from Tripp Lite to enable this feature, but it protects from hard shutdown. If it's a spike or a short power loss, the computer won't even notice and won't shut down. Great system. I have my satellite box (no reboot) and my phone answering machineplugged in.DO NOT!!! plug in a laser printer!!!

I don't think it draws that much, but why keep it on when not in use? Just plug it in to check then disconnect, I think would be best.

Difficult to answer your question since you did not specify conditions. The battery is rated at 7 amp hours meaning it will provide 1 amp of current for 7 hours , or 1/2 amp for 14 hours. Under no load, that is no current draw, and not connected to a charger, it will probably hold its charge for 3 to 6 months or even longer when it is brand new. However, not connected to a charger is not a typical way this type of battery is used such as in an alarm system. In my application, the battery is connected to a charger and normally under no load. I normally have to replace the battery every 3 or 4 years. Difficult to answer your question since you did not specify conditions.

This unit is run off of AC plugged in power. There is no spot for batteries. This is a fairly big size unit maybe 14 inches H, 10 inches W and 6 inches D, roughly.

Not good. It drains really quick depending on what you are doing. A full charge would last about 1 to 2 hours. However I have it plugged in all the time so it is not a problem for me.

It is OK to keep it continuously plugged in. When the Cyren is off and fully charged and USB connected to 5.14V, it draws 0.00 Amps (I have a USB volt-amp meter). The battery is being charged only when it needs to be charged, and that is good for the battery.

Standby current is 500uA or less - temperature dependent at 12.00V. Yes, I meant micro.Operating current is 0.315A warm and about 0.385A cold at 12.00V. Like most SMPS, current draw goes down as voltage increases and vice-versa (0.290A draw at 13.80V).I purchased two units and they're within 1% of each other.These are quite efficient and work well from 6-14V -- perfect for solar/gelcell application.

No, that's ridiculous. I ran mine last weekend for a solid seven hours, with intermittent bursts on full power to get from one point to another. I also run my fish finder off the same battery. When I got home the battery was still 80 percent charged, and that's the most I've ever drawn it down.

I'm not quite sue--I've never used it long enough to drain a charge. My guess would be several hours. Sorry I can't be more helpful.

I'm not sure about the amp draw, but I can tell you a fully discharged battery takes about 2-1/2 to 3 hours to fully recharge.

Like LFM says, put the "Watt's Up" between battery and load. As long as it has some current from the battery, the unit will stay on and keep a running tally of amp hours, max/min voltage, etc.
