charging with a/c adapter: This may be a stupid question but how do I know when the batteries are fully charged?

I really really really want to flame you but I won't. The adapter whether it be the car plug or anything else is to power the unit and power the unit only. It will automatically turn on when it has power and when it loses power it will then prompt you that it will shut off in 10 seconds unless you tell it to rely on the battery power. So the unit itself is NOT a battery charger and will rely on the external power source first and once that external source is cut it will rely on battery power.

Should start to charge almost immediately either you have a bad battery or a bad charging circuit assuming that the AC adapter is good

When you install the batteries or battery in the charger the light will turn green. This is kind of a gauge that signifies they are connected properly. When you plug the charger in it will turn red and this means it is charging. It will turn green again while plugged in and this means it is finished charging. Best to unplug and remove batteries because if you leave them in the charger while it is unplugged it will drain them slowly.

Hi Thomas Q., I ordered mine and plugged it in and I believe it has charged the batteries. I will check tonight when I get home to see if they were fully charged and let you know. I do know the charger red light came on when I plugged it in which should signify it is working and charging.FD

You should charge the battery until the adapter's light turn blue. When the battery is charging, the light turns red and once it is fully charged, the light turns blue. If you have any further inquires, please contact us back at our customer service email. Thank you.

I've had mine about 40 days. Everything is working fine, better than expected actually. Have charged both batteries twice with no issues. As stated earlier, the charger does get warm. Probably warm enough to 'burn off' dust if it has any. As an HVAC mechanic, I generally get calls in the fall for dust getting burned off ( particularly in gas units), and people think their house is on fire. Can't guarantee that's what you're experiencing, but that would be my first guess. If in doubt, send it back

sir, i am confused by your statement. i would verify the battery is being charged. since it is DC current a simple multimeter will provide this information.i purchased this battery for a back up security system. the system becomes active in the event of a power loss.

I'm not sure. I do know when the indicator light turns green it is fully charged

don't count on any new battery to be fully charged! mine had a charge but I'm sure it was not 100% charged. Once installed your system should start charging it.

I just plugged mine in to make sure. Yes it can be on while it's charging from the A/C plug.

1st -- I suggest that you attach the battery terminals first (make sure of the color coding: red to red, black to black)2nd -- select the setting you wish (low amps for slow overnight charge; higher amps for 1-2 hour charge; start for highest amps).3rd -- plug in the charger to your power source.The meter and the lights will tell you when you have a full charge.

My model doesn't use batteries. its an AC adapter. :( Stopped charging about a week ago.. Was fading for about a month. Lights on base-console no longer light up either.

It depends largely. There are instructions in the box on how to care for the battery, but...basically it has to be charged to aat least 12.6 volts. It would not hurt to charge it fully, that's what I did even though mine read 12.8. As for chargers, use a charger capable of charging an agm battery. I charged mine at 15 amps bit over read lower is better. Not sure, but mine is going strong as has for The 3 months I've owned it

I don't remember if it had any charge when I got it, but I always fully charge the batteries so they are ready for use. I don't want them to die on me when I need them.

All you have to do is plug into the wall and put your batteries in the container. The side bar will let you know once the batteries are fully charged.

When you plug in the battery the little green light will come on to let you know it's charging. When that light has turned off then the battery is fully charged and you can put a new one in.

usually i plug it in and the green light comes up and i can see the battery symbols for the respective slots i put the battery in flash with an indication. if the batteries show up already full, the batteries might either be fully charged or no good.
