FAQ
Frequently Asked Questions
How do you convert Ah to mAh? +
Multiply Ah by 1000. For example, 100 Ah × 1000 = 100,000 mAh.
How many mAh is a 12V 100Ah car battery? +
A 100Ah battery equals 100,000 mAh (delivering 1,200 Watt-hours of energy at 12V).
Why are deep cycle batteries rated in Ah rather than mAh? +
Industrial and solar batteries store large amounts of power. Describing a 200Ah battery as '200,000 mAh' is unnecessarily long.
