The problem here is that "Ah" (ampere-hours) is not a unit of energy. To convert that to units of energy, you need to multiply by the voltage of the battery. The result, of course, will vary depending on the battery type.The result of this multiplication would give you ampere-hours-volts, or watts-hours (watts times hours). Therefore, you can then divide by the number of watts used, to obtain the time (in hours).

How many hours will a 100 Watt light run on a 40 ah battery?
To calculate how long a 100 Watt light can run on a 40 Ah battery, first convert the battery's amp-hours to watt-hours. A 40 Ah battery at 12 volts provides 480 watt-hours (40 Ah × 12 V = 480 Wh). Dividing the total watt-hours by the power of the light gives you 4.8 hours (480 Wh ÷ 100 W = 4.8 hours). However, this is an ideal calculation; actual runtime may be less due to inefficiencies and battery discharge characteristics.
How long will a 12 volt battery last using a 20 watt light?
To determine how long a 12-volt battery will last powering a 20-watt light, first calculate the current draw in amperes using the formula: current (A) = power (W) / voltage (V). For a 20-watt light at 12 volts, the current is approximately 1.67 amps. If you have a typical 12-volt battery with a capacity of 50 amp-hours, you can estimate the runtime by dividing the capacity by the current draw: 50 Ah / 1.67 A ≈ 30 hours. However, actual runtime may vary based on battery age, discharge rate, and efficiency.
Is it all right to replace a 12v 4.5ah battery with a 12v 4ah battery in UPS?
I'll answer my own question since no one answered it. I replaced the 2 pcs. 12v 4.5ah battery w/ 2pcs. 12v 4ah battery. It seems alright since it is now working fine for at least 2 months w/ 1 PC connected to the UPS. What I'm concerned though is that the UPS will overcharge the batteries since the replacements have a lower ah rating. --------------------------------------------------------------------------------------------- The charging will be fine - it is how long the UPS will run for (if you mains cuts out) that has been affected by your replacement.

Can a battery be made of steel?
yes if that steel can carry charge w/o any lose in its capacity due to day light changes.

What does it mean Discharged battery in car?
It means just that, the battery has been drained, has no power left. W/o battery the engine can't crank, w/o cranking it won't fire, w/o fire it won't run.
Why does your battery die when the battery is new and alternator is fine?
Something is on and drawing power from the battery. Dome, trunk, curtorsey, glove box, under hood light are suspect. You can also have a relay stuck closed as in A/C, P/W, P/DoorLock, P/Seat, etc.
Why does the battery light come on when you accelerate?
The alternator may not be able to keep up to the voltage requirement of the vehicle check voltage output of alternator w/mechanical gauge
