Is it normal for some extended batteries to not give accurate sensor readings?

I am using this battery Amazon.com: [Aftermarket Prodcut] 3600mAh Extended High Capacity Battery+Back Cover For LG MS770 Motion 4G: Cell Phones & Accessories



On battery apps I have tried, it always gives me a reading of 4.0V-3.9V and 40C temp, but never changes, when the battery is suppose to be a 3.7V battery and the battery runs cool for the most part. Basically the readings are kind of stuck on the same temp and voltage. Now I am assuming it's because it is a cheap battery.


I have fake battery mode on.

I have an app that shows volt and temeperature
I have to close and reopen it to get a fresh reading

All the apps I tried do that. It just says 40C all day and 4.0v or sometimes 3.9v

Yes. It is the biggest bug with the Motion. It doesn't recalibrate when you put in an extended battery.
