Buy a "native" battery for a laptop, or a "universal" one?

Question

Iron

There is an HP 6710b laptop - an old one, but quite working - with 3G of memory and an SSD.
The battery is dead AT ALL - it does not hold at all, the laptop does not turn on without a network adapter.
The laptop lives at home, but occasionally you need to use it offline.
Actually questions:
1. What is more rational: to buy a "native type" battery for $ 75, or a universal one (PowerBank) for about the same money?
2. Who has experience with universal batteries? Share your impressions.

Answer 1

Buy a new battery on Aliexpress for $20-30. though he is not "native" but enough for a couple of years.

Answer 2

If I were you, I would take apart the existing one and replace the batteries with the same / similar ones.

Answer 3

LazyFire only "electronics" that are in the battery, you can't fool it, it will consider that the battery is dead and will cut down the laptop :(

Answer 4

Lord, replacing cans, controller firmware ... Buy a battery and don't suffer)) These kulibins will not bring you to good)
