Battery upgrade. pavilion gaming 15

[pavilionenjoyer]

Does anyone know where i can find a good battery replacement with higher capacity
 for my hp pavilion gaming 15? Currently the battery last for around 2h of watching 
yt/browsing/writing in word. original capacity was 52500 but not its only 42000 
(i think its 11.55v).Extra 10000 wont give me more than 45min of additional use so i
 dont think its a good idea to buy an original replacement. I tried to change power
 plans and bios to squeeze extra battery life but nothing helps. Never noticed it 
before because i mostly used it stationary. Im going to uni i would like to use it
 more like a laptop than a gaming machine but the battery wont allow it. (i thought
 about buying a pc but for now carrying it for weekends home and back just to play
 for a little seems like a waste of time). It works well for me because its really quiet 
(under small load fans never start). I can only find bigger battery packs for older 
pavilions with removable ones but i have no luck with finding replacements for my laptop.

HP Pavilion Gaming 15-dk10000 Laptop PC (8WQ69AV) is an invalid model/product (too many zeros). The 15-dk1000 machines use same battery which is (3-cell, 52-Wh, 4.55-Ah, Li-Ion, includes cable) part # L48495-005

No higher capacity batteries
