How many watt-hours of energy are there in a battery?

Your available energy will be 8 (number of batteries) x 12V (battery voltage) x Battery Capacity (Amp-hours) and this result will be in Watt-hours. Sometimes batteries will list this number. Let us assume you have 8, 1 amp-hour batteries. So you will have 96 watt-hours of energy available.

How many watts are in a battery?

Our lights run on 12 Volts. So if we plug that into the formula we realize one amp is the equivalent of 12 watts of power. Thus, our three batteries actually contain 42 Watt Hours (12 x 3.5), 78 Watt Hours (12 x 6.5), and 240 watt hours (12 x 20) respectively. From here, your total battery capacity in time is pretty easy to calculate.

How do you calculate watt-hours of a 12V battery?

The watt-hours of your battery bank. You said you have eight 12V batteries in your current setup, now you need the capacities (in amp-hours) of these batteries. Your available energy will be 8 (number of batteries) x 12V (battery voltage) x Battery Capacity (Amp-hours) and this result will be in Watt-hours.

Do LED lights work off a battery?

Perhaps you'd do best using some LED lights. LEDs intrinsically work off dc power. You can directly get plain LEDs and power them off the batteries. This is safe, because there are no high voltages at any point in the circuit. According to a Wikipedia article, new white-light LEDs are about as efficient as fluorescent bulbs.
