Ah stands for Ampere hours. It is a measure of capacity, how much electricity the battery can hold.
Eg: A 12 volt 5 Ah battery can deliver 12v at 5 amps for 1 hour. Or 12v at 0.5 amps for 10 hours and so on.
Remember. Voltage is supplied by the battery but current/ amps are drawn by the appliance. Power in watts is calculated as volts x amps. So for instance a 12 volt bulb drawing 2 amps is: 12x2=24 so it is a 24 watt bulb. so on a 12v 5ah battery it will burn for about 2.5 hours. This is why car batteries are quite big for only a 12 volt battery, the massive current drawn by just turning the engine would flatten a small battery, and probably still wouldn't start even then.

How much load you can put on the 150 ah battery?
Ampere Hour (Ah)
The capacity of the battery is represented in Ah. It is the
amount of current a battery can give during one hour of charge /
discharge cycle. High capacity batteries (100 Ah, 150 Ah) are used
to power inverters to get sufficient backup time. The formula to
select the battery power (Ah) is Load in watts / Voltage of
battery x Backup hour.
For example if you wants to run 400 watts load on 12 volt
battery for 3 hours,...

Does more ah in a battery mean its stronger?
Depends on what you mean by stronger. Ah stands for ampere hour,
which is a unit of energy. A battery with 1 Ah can deliver a
current of 1 Ampere for 1 hour, or 2 Amperes for 30 minutes,
etc.
The voltage of a battery tells you how much current the battery
will produce through a given resistance; more voltage is probably
closer to what you mean by stronger, since knowing the current and
the voltage allows you to know the power...

Describe the difference of V and Ah in a battery?
V is the batteries rated voltage. Ah is the amp-hour of the
battery. This is a rating of how many amps it can supply for a
given period of time. For example a 600 Ah battery with a 100 A
load means that the battery should last 6 hours.

How long does it take to recharge a battery from dead?
Check and see how many Ah (Amper hours) your battery is. If it
is for a gas/gasoline car, then it is probably around 42 Ah;
batteries for diesel are usually around 72 Ah. Check the power of
your battery charger. It should be something between 4-6 A. You
must divide the battery capacity by the charger strength to get the
time necessary. For example: your battery is 42 Ah and your charger
is 6 A. Then the time needed will be...
