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.
What else can I help you with?
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 released by the battery. So, for a given resistance, more voltage = more power released by the battery. So: more Ah is like having a larger gas tank; more voltage is like having more horse power.
Can you replace a battery that is rated at 4ah with a larger ah battery?
Yes, it mAh or Ah is how long the battery lasts, it does not affect performance.
Can you use a 12v 7.2 ah battery to replace a 12v 4 ah battery in an alarm system?
Yes
What is 135 Ah?
135 Ah (amp-hours) is a unit of electric charge that indicates the capacity of a battery. It represents the amount of current a battery can deliver over a specific period; for example, a 135 Ah battery can theoretically supply 135 amps for one hour, or 67.5 amps for two hours. This measurement is crucial for determining how long a battery can power a device before needing to be recharged. Higher Ah ratings typically mean longer usage times before recharging is necessary.
Can I replace a 12v 33ah battery with a 12v 4.5 ah battery for a motorized scooter?
No, it does not have enough capacity (i.e. ah rating).
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.
Will a 12 volt 75 ah battery charger can be used to charge a 12 volt 150 ah battery?
Yes. In about two to two and a half hours, depending on the condition of the battery.
What type of battery that suits Toyota?
12 Volt 70 AH battery
Can a 15 ah battery can be used to supply 12v to a plc pannel instead of 14 ah battery?
Yes as long as they are both 12 volt batteries.
How many ampere-hours (Ah) is a deep cycle battery?
A deep cycle battery typically has a capacity of around 100 to 200 ampere-hours (Ah).
Would a 36V 230 Ah 6hr 335 Ah 20hr traction battery charge on a DC volts24v DCamps20A battery charger?
NO, in order to 'charge' a battery, the charging device must be at a higher voltage than the battery in order for current to flow to the battery.
What type of battery that suits Toyota innova?
12 Volt 70 AH battery
