Frequently Asked Questions
How many Wh is 3,631 mAh?
3,631 mAh equals 13.4347 Wh at 3.7V (Li-ion nominal voltage). The exact Wh depends on the battery voltage: Wh = mAh × V / 1,000.
How do I convert 3,631 mAh to Wh?
Multiply 3,631 by the battery voltage, then divide by 1,000. At 3.7V: 3,631 × 3.7 / 1,000 = 13.4347 Wh.
Is 3,631 mAh allowed on a plane?
At 3.7V, 3,631 mAh = 13.4347 Wh. Airlines allow lithium batteries up to 100 Wh in carry-on luggage. Batteries between 100–160 Wh require airline approval. Batteries over 160 Wh are prohibited on passenger aircraft.
Formula: Wh = mAh × V / 1,000. Results assume nominal battery voltage.
