12V DC is the most often used LED strip and battery voltage combo. Unless you have a special condition that necessitates a different voltage, 12V should suffice. If you want to utilize ordinary AA batteries, a battery holder that generates a 12V voltage from 8x 1.5V AA batteries may be used.
But then this question also arises, How long will a 9V battery power an LED strip?
A standard alkaline 9 V battery has a capacity of around 500 mAh, so at 5 A, it would be roughly 0.1 hour (if it could attain that capacity at that high of a current draw, which it couldn’t). 21.08.2019
How long will 12ah battery last?

How long do batteries last in LED strip lights?
Standard LED battery light sets with thicker insulation and LED lenses should last around 18-24 hours on a set of 3 AA batteries, while microdrop LED lights manufactured on thin uncoated wire could last over 100 hours with a new set of 3 AA batteries or 2 round C-style batteries. 14.02.2019
How many LEDs can a AA battery power?
You may be possible to have 8 strings of 2 LEDs with 8 current limiting resistors if you run at a low enough current. You may use a switching regulator to raise the 6V from four AA batteries to power two strings of eight LEDs. 18.10.2017
How many LEDs can a battery power?
On a 9 V supply, you can only put two LEDs in series to provide full current throughout a suitable range of battery voltages – 9.5 V down to 8 V. These will decrease around 3.4 V apiece, for a total of 6.8 V. To make up for the 9 V battery voltage, a series resistor will lower the remaining 2.2 V. 25.11.2017
Can I connect a LED directly to a battery?
Never connect an LED to a battery or power source directly because the LED will be damaged if there is too much current flowing through it. If your supply voltage is less than 12V, a resistor is sufficient for most LEDs.
How do you reduce voltage from 18V to 12V?
Two resistors might be used as a voltage divider to lessen voltage variance. The lower shunt resistor (R2 in the circuit below) helps to keep the voltage low under light load while allowing the higher series resistor (R1) to have a lower value, which lowers voltage drop under heavy load. 11.02.2017
Can I use 12V for 18V?
There is a lot of gear that operates on 12V lead-acid batteries since they were originally developed for autos. I wouldn’t attempt to put a 12V gadget into an 18V battery since it would be dangerous. However, if you need 18V for whatever reason, you may always utilize a DC-DC converter. 17.11.2014
