What is the meaning of mAh in mobile battery?
The milliampere-hour (mAh) is one-thousandth of an ampere-hour and is a technical term for how much electrical charge a particular battery will hold. As an example, using higher mAh batteries in a device with constant electrical consumption will theoretically give you longer operating times.
If you want to take a Wh rating and convert it to mAh, divide it by the voltage of the battery and multiply that by 1000. For example: A 90Wh battery that has a voltage of 12V. Divide 90 by 12, which gives you 7.5. Multiply by 1000, and you now have the mAh rating of 7,500mAh

thank you now my next question is ...if i understand correctly then there is no reason if my original laptop battery was rated 14.8V-- 45Wh 2800mAh than the replacement they say is one for my laptop shouldn't work. it's rating is 14.8 V--2200mAh 33Wh, right? But when i put replacement in machine it recognizes it but isn't charging and orange lit is blinking HELP

If you labptop was design to use battery 45Wh 2800mAh a much lower battery 33Wh 2200mAh is not going to work.

Toshiba says replacement battery is correct one and do not carry one like original. So now what???

If the laptop is too old, support may have ceased for it and the correct battery no longer available.

If you bought this battery from Toshiba, then it's faulty, return.

If you bought this battery third-party, all bets are off.
