why would you use battery power unless there was an electrical cutoff? and, when you do go to battery power, and run low, how do you recharge?

You would use the battery power if there were no electrical outlets such as in the backyard. It comes with a charger so you just plug it in the outlet.

I can only answer for the one that I own. I can plug it in and it runs just fine, especially when battery is low. If your battery is completely dead, with no chance of ever charging again, it probably has a short and it, theoretically, will NOT work when plugged in either due to the shorted battery. I hope somewhere in what I said you find the answer that you were looking for.

If you use a battery tender to maintain your batteries when not in use, then I would imagine you have the pig tail attached. Just plug into the pig tail. However if you are not charging the big battery in some way it will draw it down. My opinion, if you camp a lot, invest in a good quality solar charger.

If it is out of warranty and your battery is dead you can still have it plugged into power and run the speaker. You would only need the battery if you wanted to run it off the grid.

? i use it to there is no charge left in it , then recharge , that takes about 5 hrs to charge , thats why i bought 2 of them , they can run the unit for about an hr , as with all my battery operated tools , i let the battery run out , then completely recharge them , you may have a defective battery , if you get a new 1 , dont try using it , till its completly charged , 5 hours , then use every bit of power left on it before recharging , battery's have memories

It is to power the cordless, I didn't realize this until you asked the question and I checked. I thought the batteries were just in case you havepower interruption, that's not the case. I guess that would be another strike against it.

I don't know. I have never run the battery all the way down. I have always run down first. It takes hours to recharge fully, though, even if you only use it to trim a bush or two.

Or you can buy one of those quick battery pack rechargers for phones and use that. Unfortunately, you'll have to take a break from using it to recharge it.

The battery is a backup in case of power interruption. From a practical viewpoint you need a low voltage power supply.

Most of these have a "low voltage alarm" and the power inverter may automatically stop functioning, but other 12V items (like something plugged into the lighter socket) will not be stopped. So you need to monitor those items and turn them off before it goes too low. FYI, I've seen on battery distributers websites statements like "Draining the battery to 0V just one time can make it no longer hold a charge", so once it seems low stop running things before it gets that bad.

I am having trouble running it off AC power. The plug isn't designed well and it fell out of my power strip, so the battery ran out of charge totally. Now it's plugged in, but it doesn't want to work yet because the battery is not charged. So, it runs off the battery only, but you can try to keep the battery recharging as you use it by keeping it plugged in.

You should have at least a basic charge controller to avoid over-charging your battery and possibly damaging it. The panel has built-in diodes to prevent discharging your battery when there's no light on the panel.

I believe it is the design to merely run off a battery pack. Since it is an emergency radio, the design asumes that electricity is not available for the average radio or television thus engaging this item to usage.

Just be aware of the difference between a completely run down battery attended to immediately, and one that has been totally abused / ignored forever. Attempts to bring zombie batteries back to life are an iffy proposition, and if they don't - don't blame the charger. -grin-

that's what I am doing - here's what i am finding...the control item (using a kill-a-watt) is still drawing .005 amps when everything else is off...i know this is practically negligible and in the scheme of things it's not really gonna matter money wise, just led me to the question that if the most least power consumption device (i.e. -0-) was the control item there would be absolutely no draw whatsoever. Thank you for your replies and if I am completely off base, please let me know

Sam, I am not sure, but it sounds like a battery issue. Mine works from a half block away from my house. I assume you pulled the little battery saver piece all the way out.

That is a good point, but I rarely have a dead battery in my trailer (solar) and I do have a battery alarm when the voltage gets low. And I don't have to worry about changing a battery on the monitor when it goes bad. Good luck with your research.
