This Lead Acid Battery has a power of 12 V and a capacity of 1.3 Ah. (The capacity is mentioned in the Question itself, no need to repeat it in the Passage)
This does not directly tell you how much energy the battery can store, but can be a more useful value in deciding how long a circuit will run from a battery. For example, a car battery might be rated for 50 Ah. That means in theory it could source 50 A continously for 1 hour and then go dead.
Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
A kiloWatt-hour is therefore 3.6 MJ. Batteries are usually rated in units of current times time. This does not directly tell you how much energy the battery can store, but can be a more useful value in deciding how long a circuit will run from a battery. For example, a car battery might be rated for 50 Ah.
10kWh from 12V batteries -> 833Ah capacity Or seventeen 50Ah car batteries in parallel You forgot the time aspect: your answer assumes the 10kW must be delivered for one hour. A single car battery can deliver 100..200A, so for a short time period 4 batteries might be enough. The question as framed does not have a time element.
However, the amount of current we can really draw (the power capability) from a battery is often limited. For example, a coin cell that is rated for 1 Ah can't actually provide 1 Amp of current for an hour, in fact it cant even provide 0.1 Amp without overextending itself.
How to Measure Battery Capacity
The formula for determining the capacity of a lead-acid battery is: Capacity (Ah) = (RC / 2) + 16 For example, if a lead-acid battery has a reserve capacity of 120 minutes, its capacity would be: Capacity (Ah) = (120 / 2) + 16 = 76Ah It is important to note that the capacity of a lead-acid battery decreases as the temperature drops. At 32°F ...

How Many Watts Is A 100ah Battery?
kWh (kiloWatt-hour) or Wh (Watt-hour) is the unit that measures Electrical Energy. A 12V-100Ah battery can store 1200Wh or 1.2kWh of energy, and therefore could be said to have 1.2kWh of energy capacity. If the 100Ah battery is rated at 24 Volts, such as this Ampere-Time battery, it can store 2400Wh or 2.4kWh of energy.
