I recently bought a new battery for my laptop. Since then it is charging very slowly. About 3-4% in an hour. Last battery charged a lot faster. Old battery was 4400 mAh and new ones lable says it is 5200 mAh. I was hoping someone can help me to understand what is going on here. When I charge this battery Aida64 says that charge rate is 725000 mW which seems to be very high. Also from Aida64 and BatteryInfoView it shows full charged capacity 48840 mWh and designed capacity 48840 mWh. It is a Lithium Ion based battery by COMPAL PABAS0241231 serial number 41167. The battery holds charge pretty well, but charging time is very long. Last battery died on about 95% when my laptop suddenly turned off and wouldn´t start without the charger connected. This new battery has an indicator of its own which shows how much it has charged and it seems that windows battery indicator is showing right charge percetage.

Question is why is it charging slowly and what could I do to fix it or troubleshoot? Updating BIOS? Calibrating battery? How to do those things? Or it might be faulty charger?
I attached a Piroforms Speccy report just in case.
