1500mAh
The amount of electrical energy supplied by the battery is measured in units called watt-hours (Wh). This value can vary depending on the capacity of the battery, which is typically listed in milliampere-hours (mAh) or watt-hours (Wh).
the 56 wh has a higher capacity and will last about 30 mins longer.
Wh means Watt-Hour. It indicates how long your battery will last. The higher the Wh, the longer your battery will last.
The letters Wh means watt hours. this is how many hours of power the battery can store. The larger the number, the more power the battery can store. This is important for laptops, smartphones, and tablets. or Another way to measure the capacity of the battery is in watt-hours(wh). wh is calculated by multiplying the number of Amps with the battery voltage.
These are two common ways battery capacity is measured. Wh stands for "Watt hours", and it's a measure of the actual energy content of the battery; it measures how much power (watts) the battery can supply multiplied by the number of hours it can do so before it runs out. Most batteries are labeled with a capacity in mAh (milliampere hours). This is a measure of the electric current the battery can supply multiplied by the number of hours it can do so. Example: if a battery is labeled 3000 mAh, it should be able to supply 3000 mA of current for one hour, 1500 mA of current for 2 hours, etc. You can figure out the Watt hours for a battery by multiplying the voltage of the battery by the amp hours (amp hours = millamp hours / 1000).
The equivalent of milliampere-hours (mAh) in watt-hours (Wh) can be calculated using the formula: Wh = (mAh × Voltage) / 1000. To convert mAh to Wh, you need to know the voltage of the system, as it directly influences the energy capacity. For example, if you have 1000 mAh at 5 volts, it would equal 5 Wh.
Only if the battery is rated at 11.66V. mAh / 1000 => Ah (4800 mAh = 4.8 Ah) Ah * V => Wh (4.8 Ah * 11.66 V = 55.97 Wh)
Answer #1:56watt = 56000mw,1000milliamp = 1amp,watt = amp x volt = watt/volt,if the battery is rated 11.1v,so 56000mw/11.1v = 5 045.04505mah==============================Answer #2:Answer #1 has a big ' if ' hidden in it.In general, 56 Wh = 56,000/voltage of the battery mAh and for ANY number of Wh ... call it ' P ' ...P Wh = 1,000 P/battery voltage mAh .
The battery capacity of an iPhone varies by model, but most recent iPhones typically hold between 10 to 15 watt-hours (Wh). For example, the iPhone 13 has a battery capacity of approximately 12.41 Wh, while the iPhone 14 Pro Max holds about 16.75 Wh. This capacity allows for several hours of usage depending on the tasks being performed.
The amount of energy stored in a battery depends on its capacity, typically measured in watt-hours (Wh) or joules (J). For example, a battery with a capacity of 100 Wh can store 100 watt-hours of energy. The energy stored in a battery can be calculated by multiplying the voltage (V) of the battery by its capacity (in amp-hours, Ah).
The difference is an increased battery capacity (hence longer runtime). A batteries capacity is measured in Ah (or mAh) and is the product (ie multiplied together) of the current being drawn and the time the current is drawn for. Thus a 4800 mAh battery can supply a 2A current for 2.4 hours (ie 4800/2000) while a 4400 mAh battery can only supply a 2A current for 2.2 hours.
On the Internet I saw a NiMH battery 12V 50 Wh for about $50 USD so ten times that $500
