10,000 mAH is equal to 10 AH.
Solution: Ampere-hours (Ah) and milliamp-hours (mAh) are two units of measurement for battery capacity.
Because 1 amp hour = 1 amp x 1 hour, 1 milliamp hour = 1 milliamp x 1 hour and 1 amp = 1000 milliamps.
So 10,000 mAh = 10,000 mA
That is, 10,000 milliamp-hours is equivalent to 10 amp-hours.
Detailed information:
1. Classification of battery capacity and its units
Battery capacity is divided into actual capacity, theoretical capacity and nominal capacity and capacity.
Battery capacity refers to the amount of energy stored in the battery. Battery capacity is measured in amp hours and milliamp hours.
And 1 amp-hour = 1,000 milliamp-hours.
2. Test methodof battery capacity
Charge a battery with constant current and voltage, then discharge it at constant current. The amount of electricity released corresponds to the capacity of the battery. For example, if the capacity of a lithium battery is 1000 mAh, then the charge and discharge current is 1000 mA. If the maximum battery voltage is 4.2V and placed at 3.0V, the capacity released is the true capacity of the battery.

Battery comparison is as follows:
Lithium battery
——
Lead acid battery
1. Rechargeable battery
2. Lifespan (500 times
—— 400 times)
3. Specific energy (150W·h/kg——40W·h/kg)
4. ——
6~8h)
5. Discharge energy efficiency (discharge efficiency of lithium battery can be more than 90% - discharge efficiency of lead acid battery is sugreater than 80%)< /p>
6. Price (higher
24V/10Ah price: about 700 yuan
—Lower price
24V/12Ah price: about 180 yuan)
7. Volume
(Small size
The volume of lithium-ion battery is 2/3 of the volume of lead-acid battery
——Large size)< /p>
8. Weight
(Light
Only 1/3 ~ 1/4 of the lead-acid battery< /p>
——Heavy weight
)< /p>
9. Batteries with the same specifications, because lithium batteries are composed of several cells, although the individual discharge efficiency is high, the overall efficiency has decreased, so the mileage of the two batteries is about the same)
10. Pollution in production and use (there is pollution in production - there is a large amount of lead and acid in lead-acid batteries. Afterwards they are thrown away, if not handled properly , they will pollute the environment).
11. Discharge (susceptible to discharges pr(waves and damage from short circuits - vulnerable to damage from deep discharges)
12. Charging and maintenance (complex and high maintenance costs - simple and low maintenance cost). )
