How long will a 12V 2A led light strip work off the fully charged 8 AAs?

Batteries are rated in mAh or milliAmpHours. AA batteries are normally 1500 mAh. This means you can draw 1500mA for an hour or 1.5 Amps for an hour (just removing the milli by multiplying by 1000).If you are drawing 2Amps this would last for 1.5Ah/2A this leaves you with 1.5/2 hours or .75 hours or 45 minutes.

Charge the unit for 24 hours initially. The two red LED lights will be on and the green LED light may be flashing. After that, once the green light starts to flash charge for 1-2 additional hours. Disconnect the extension cord and depress the battery status button. If all three lights illuminate, the unit is fully charged. I do not recommend using the 12 volt DC charging/cigarette receptacle method. It can damage the unit.

This has a fair chance of running those lights, but keep in mind this is a battery with a limited supply of power. The battery is rated as "26 amp-hour" hinting it'll give you 1 amp at 12V for 26 hours, or 2 amps for 13 hours, etc, so for it to last 10 hours means you can't use over ~2.5 amps. When running things off the inverter, the overall power used is about the same but the 12V gets changed into 120V and the amps get changed from 2.5 amps to 0.25. I just tried a string of 26 LEDs (with the 1-2 inch cone on each) that shows 0.04 amp draw, so I could only put 5-6 of those together if expecting 10 hours. You may need to check yours to be sure of what yours needs since they may be different (I used the "kill-a-watt" meter to measure mine that you may want to consider getting to see exactly what yours use).

This is a delayed contact closure, not a power supply. You have to supply power for it to work.From the picture it can handle upto 10A. Your led only draws 2A.

Yes just make sure that you get 12v dc LEDs and think you need mor then one repeter each strip is 16 feet long and can draw 72 watts at 12v each

About any of the led strip supplies will work for this / these. I use the ones that look like PC lap top supplies. Lighting EVER® Power Adaptor, Transformers, Power Supply For LED Strip, 12V, 3A Max, 36 Watt Max . These are about $10.00 each. You will need about 30watts (<3 Amps) per strip. I have found the supplied controller will drive at least 2 strips pretty well. It is recommended not to use more than 2 strips in series (one plugged into the next.

We are using these batteries to power LED lights in a semi trailer, being used to haul Marching Band equipment to competitions and football games. We have very bright LED lights installed (3 strips that consume about 11amps each, and 4 floods that consume another 10 amp hours. With all that, I can theoretically keep all the lights on for about 12 hours. I have not tested this to failure, but have kept all the lights on for roughly 5 hours, with no issues. We have a solar panel that charges the batteries all week (between band and football events), and then we use them on Friday and Saturday events, so far so good! Brent Jensen

I'm not sure. The longest I've left the flashlight on the charger is overnight. It's not good for any battery to be charged constantly.

If you connect it to a 12V battery it should work fine (no need to plug it into an outlet). The whole strip needs 5 Amps or 60 Watts to work properly. If you cut the strip short you can use a smaller battery. A battery pack of 8 alkaline batteries (AA, C, or D) will work also.

Yes, it works great. I have two 20" Diamond White LED strips under my bed cover. Charged the unit when I put them in 9 months ago. Use the lights at least three times a week and have not had to recharge yet. Highly recommended.

The manual says it is a "smart" design, but it also says it takes 14 hours to charge 8 AA cells. It's unlikely the 9V circuit is zdv design, but at 12 hours charge it doesn't matter because the 9V will not be hurt by a C/10 charge rate.

I used a 12v battery ( which is charged from a solar panel,) to power the timer and the led strip lights. Works perfectly. Lights run 4 hours a day, timer is always drawing a small amount of power from the battery.

Should work just fine as long as your 12V LED can plug into a cigarette lighter socket

i haven't had to recharge as of yet. led lights last fairly long, so i can't answer your question yet.

each 21 LED strip takes 1.5 watts and the typical power supply used (12 Volts at 1 amp) is 12 watts so the absolute maximum is 8 but I would not use more than 6 staying at 80% of the power supply rating. It typically looks like the supplier uses between 3 and 5.

7.2V - should last 90 minutes on a charge (one of the reasons why I purchased this)
